The Hollow

Lucy Angkatell invites Hercule Poirot to her estate for a party.  As a lark, she stages a mock murder for the detective.  By the end  of the evening, everyone is surprised to discover a dead body in the pool.

Doctor John Cristow, husband of Gerda, is having an affair with sculptress Henrietta Savernake.  The beautiful Veronica Cray, a former flame of John's staying at a nearby cottage, appears at the party looking for matches.  John walks Veronica back to her cottage and returns at 3 am.  The next day, Gerda Cristow stands at the edge of the pool next to her husband's bleeding body, a gun in her hand.  Lucy, Henrietta and Edward, a cousin of Lucy's are also present at the scene of the crime.  After uttering one word "Henrietta", John dies.

It would seem obvious that Gerda is the murderer.  However, no one actually saw her pull the trigger.  Henrietta takes the gun away from Gerda and it falls into the swimming pool, destroying the evidence.  Lucy kept a pistol in her basket of eggs, but it is of a different calibre than the one used to kill John.  Henrietta looks suspicious after a strange doodle is found in her sketchbook.  The murder weapon turns up in Poirot's hedge, but with fingerprints not matching any of the suspects.

It turns out Gerda had two pistols, one to shoot John and the other to use as a decoy.  Henrietta assumes that john's appeal to her is to help Gerda.  She takes the pistol out of Gerda's hand and later hides it in the hedge.

Midge Hardcastle is in love with Edward.  However, Edward is in love with Henrietta who has rejected his countless marriage proposals.  Realizing Henrietta has changed, and realizing that Midge is no longer "little Midge", he proposes to the latter.  However, still believing Edward is in love with Henrietta, she turns him down.  Distraught, Edward attempts suicide, but is saved by Midge.  Realizing he really loves her, she agrees to marry him.

Gerda and Henrietta are about to sit down for tea when Poirot arrives.  The detective, concerned that once Gerda is cornered she will murder Henrietta, switches the tea cups.  Gerda drinks from Henrietta's cup and dies.  Distraught, Henrietta visits one of John's former patients for closure.  She decides to make a new sculpture named "Grief".

The Moving Finger

Jerry is injured in a plane crash after which he and his sister, Joanna, take up residence in Mrs. Burton's country house in Lymstock.  They receive an anonymous letter accusing them of being lovers while they are simply siblings.  It turns out many people in town are receiving poison letters.  Mrs. Symmington receives a poison letter claiming that her husband is not the father of her second son; later she is found dead.  Beside her body is a glass containing potassium cyanide and a note stating:  "I can't go on."

Her 20 year old daughter, Megan, stays with the Burton's for awhile.  The Burton's maid receives a call from the distraught maid of the Symmington's.  They plan to meet, but the former never shows up.  The next day her body is found in the cupboard under the stairs by Megan.

An investigator from Scotland Yard concludes that the poison letter writer/murderer is a middle aged, prominent Lymstock resident.  The vicar's wife calls her own expert, Miss Marple.  Elsie Holland, governess to the Symmington boys, receives a poison letter. The police catch Aimee Griffith typing on the same typewriter used by the murderer and arrest her.

Jerry heads to London to see the doctor and takes Megan along.  They stop at the dressmaker to get Megan some clothes.  Jerry realizes he has fallen in love with her and proposes, but she turns him down.  Jerry then asks Mr. Symmington if he can woo Megan.  Megan blackmails her stepfather by saying she has proof that he murdered her mother.  Mr. Symmington pays her off, but does not admit his guilt.  After giving Megan a sleeping drug, he tries to murder her, but Jerry and the police are waiting for him.  Jerry rescues Megan and Mr. Symmington is arrested.

Miss Marple explains that the letters served as a diversion.  Mr. Symmington, in love with Elsie Holland, wanted to get rid of his wife.  He modelled the letters on a case that he worked on as a solicitor.  Miss Marple, knowing that it would be hard to prove his guilt, had Megan lure him into a trap.

Megan realizes she is in love with Jerry who buys Miss Barton's house for them.  His sister Joanna marries a doctor from Lymstock.  Emily and Aimee go on a cruise together.

The Body in the Library

There's a dead body in the library at Gussington Hall.  The woman is flashily dressed and heavily made up.  The owners, Colonel Arthur Bantry and his wife, Dolly, do not recognize the woman.  Colonel Bantry phones the police while his wife calls Miss Marple.

Suspicion is cast on the neighbour who makes movie props and whom the Colonel dislikes.  Blake has been dating another platinum blonde, but his girlfriend is still alive.  The autopsy reveals the woman was drugged, died between 10 pm and 12 midnight.  Despite her appearance, she was still a virgin.  She is identified as Ruby Keene, a dancer at the Majestic Hotel.  A fellow dancer, Josie, and had had Ruby fill in for her as an exhibition dancer with Raymond Starr, the hotel's tennis star and dance instructor.  However, when Ruby went missing Josie still had to perform, despite her ankle.

Conway Jefferson, a hotel guest who had become fond of Ruby, phoned the police when she went missing.  Several years before, Conway had lost his wife, son and daughter in an airplane crash in which he had also lost his legs.  He is now accompanied by his daughter's widower, Mark, and his son's widow, Adelaide, who are now his heirs.  Conway planned to adopt Ruby and leave her as sole heir to his fortune, which would leave Mark and Adelaide with nothing.  However, they were accounted for, playing bridge in the hotel ballroom with Conway and Josie.  George Bartlett was Ruby's last dance partner that night.

The police suspect that Ruby sneaked off to meet someone who strangled her.  Bartlett's car is found with the corpse of another girl, Pamela.  She had been approached by a director offering her a screen test when she disappeared.  Basil confesses that after quarreling with Dinah, he went home and found the body and dumped it in the Bantry's library.  Conway plans to change his will and leave his money to a dance hostel.  At 3 am an intruder tries to murder Conway in his bedroom.

Miss Marple discovers that Mark was married to Josie.  They murdered Ruby so that she would not inherit Conway's money.  The two were also responsible for Pamela's murder.

Evil Under the Sun

Hercule Poirot is holidaying in Devon.  Also at the hotel is a beautiful actress named Arlena, a known flirt.  She is vacationing with her husband, Kenneth, and teenage stepdaughter, Linda, who hates her stepmother.  Arlena flirts with the handsome Patrick Redfern, angering his wife, Christine, a former schoolteacher.  Other guests at the hotel include Sir Horace Blatt, a braggart, Major Barry, an Anglo-Indian military officer, Rosamund Darnley, a dressmaker and former girlfriend of Kenneth, Carrie Gardener, an American tourist, and her husband Odell, Reverend Stephen Lane and Emily Brewster, a quiet spinster.

Arlena, known for sunbathing, is found face down in the sun, dead.  Poirot collects alibis.  Linda drops a parcel of candles when Christine asks her to Gull Cove.  Arlena paddles to Pixy Cove for a rendezvous.  Both Kenneth and Patrick look for her.  Patrick asks Emily to join her daily row.  He finds a Arlena's limp body lying face down, arms outstretched.  He stays with the body while Emily fetches the doctor who concludes it is death by strangulation, likely a male.

Police questions the suspects.  Kenneth was heard typing letters responding to figures in previous mail.  Linda lies and says she was fond of her stepmother.  She and Christine went to Gull Cove at 10:30  and didn't return until 11:45.  The Gardeners were with Poirot the entire time.  Emily and Patrick saw Rosamund reading at Sunny Edge.  Reverend Lane and Major Barry went out.  Sir Horace Blatt spent the morning sailing.  Christine Rosamund, Kenneth and Mr. Gardener went to play tennis at noon.  Earlier in the day, Miss Brewster narrowly missed being hit on the head with a bottle tossed from a window.  Someone ran a bath at noon but no one is admitting to it.

At Pixy Cove, Poirot finds a new pair of scissors, a pipe fragment and heroin.  Poirot also smells a perfume only used by Arlena and Rosamund.  Poirot invites everyone on a picnic to test their vertigo:  Christine, who claims she has vertigo, easily traverses the bridge.  Linda overdoses on six sleeping pills, and almost dies.  Linda admits to the murder, but Poirot finds her library book and realizes she thinks that piercing a voodoo doll qualifies as murder.  Christine made her sleeping pills availabe and Linda took them.

Poirot investigates any local strangulations and discovers that Alice Corrigan was strangled.  Her husband, Edward, was too far away to have committed the crime.  Police identify Patrick Redfern as Edward Corrigan.  They identify the deceased as Christine Redfern, then known as Christine Deverill, Patrick's true love.  Patrick simply used Arlena for her money.  While Arlena did not suspect anything, if her husband discovered she emptied their bank account, he would be suspicious.  Patrick and Christine decided to get rid of her.

Patrick told Arlena to meet him that fateful day at a cave.  Christine set Linda's watch ahead by 20 minutes to give her an alibi.  Christine put on some tan makeup and pretended to be Arlena.  Emily was fooled by her.  Christine returned to her hotle room to wash off the suntan makeup, the bath that no one had admitted to.  She threw the empty bottle out the window, the one that narrowly missed Miss Brewster.  Meanwhile, Patrick called the unsuspecting Arlena out of the cave and strangled her.

Rosamund gives up her career to marry Kenneth and Linda ends up with a loving stepmother.

The Incredible Theft

Lord Mayfield, a rising politician and a millionaire, hosts a house party.  In attendance are Air Marshal, Lord Carrington, his wife Lady Julia, his son Reggie, Mrs. Vanderlyn, a beautiful American woman, and Mrs. Macatta, a forthright MP.  Joining them for dinner is Mr. Carlile, Lord Carrington's secretary.

All the guests leave the table except Lord Mayfield and Sir George, to discuss a new aircraft that will give Britain supremacy over the skies.  Lord Mayfield invites Mrs. Vanderlyn, a spy, to tempt her with the plans for the new fighter jet.  Everyone goes to bed except Lord Mayfield and Sir George.  Mr. Carlile heads to the safe to retrieve plans for the new aircraft where he collides with Mrs. Vanderlyn searching for her handbag.  Lord Mayfield spots a figure leaving the study by the French window.  In the study, Lord Mayfield quickly discovers that the plans for the fighter jet are missing.  Mr. Carlile says he definitely left the plans on the table.  However, he was distracted by a scream which turned out to be Mrs. Vanderlyn's maid, claiming she saw a ghost.

Poirot is called in the middle of the night.  He examines the grass outside the study but finds not footprints.  Therefore he concludes that the theft of the plans was done by someone inside the house.  He questions everyone and discovers that the maid did not see a ghost; she was startled by Reggie who snuck up on her to steal a kiss.  Lady Julia believes her son stole the plans as he is short on money and was unaccounted for at one point in the day.  She promises Poirot that the plan swill be returned in 12 hours if no further action is taken.

Poirot explains that Mrs. Macatta was snoring in her room, Mrs. Vanderlyn called for the maid from upstairs and Sir George was with Lord Mayfield on the terrace.  But what about Mr. Carlile and Lord Mayfield?  Mr. Carlile had access to the safe and therefore could have taken a sketch of the drawings at any time.  Poirot is convinced Lord Mayfield pocketed the drawings.  Lord Mayfield, not wanting to reveal that he was involved with a belligerent foreign power a few years before, was blackmailed into handing the plans over to Mrs. Vanderlyn.

Appointment with Death

Map of where mystery takes place courtesy https://en.wikipedia.org/wiki/Appointment_with_Death#/media/File:Christie_Appointment_105_back-1.jpg.

On vacation in Jerusalem, Poirot overhears a brother and sister conversing about their evil stepmother:  "You do see, don't you, that she's got to be killed," Raymond Boynton tells his sister.  On a trip to Petra, the stepmother is found dead, a needle puncture in her wrist.  Poirot offers to solve her murder in 24 hours.

Sarah King, who relays the tale along with Dr. Gerard, is attracted to Raymond Boynton.  Jefferson Cope wants to take Nadine Boynton away from her husband, Lennox Boynton, and the influence of her mother in law.  Confronted with her strategy to take the young Boynton's away from their mother in law, Sarah confronts Mrs. Boynton who replies:  "I;ve never forgotten anything -- not an action, not a name, not a face."

Poirot sets out to interview all the suspects.  He establishes a timeline which seems impossible.  Sarah King places the time of death well before various suspects claim to have seen the deceased alive.  A hypodermic needle was seemingly stolen from Dr. Gerard's tent.  The poison administered to the victim, digitoxin, was something she already took medicinally.  Poirot calls a meeting explaining how each member of the family discovered Mrs. Boynton's victim, but in turn didn't report the crime, suspecting another member of the family as the murderer.  No one in the immediate family would have needed a needle to commit the crime; they simply would have given her a bigger dose of the medicine already prescribed.  Therefore, Poirot suspects an outsider.

Lady Westholme is revealed as the murderer.  A former inmate at the prison where Mrs. Boynton was a warden, she had it in for the woman.  It was to Lady Westholme, not Sarah, that Mrs. Boynton had addressed her threat.  Disguised as an Arab, she had administered the hypodermic needle.  Eavesdropping in an adjoining room, and not wanting her criminal history to be revealed, Lady Westholme commits suicide.

Happier times ensue for the family as Sarah marries Raymond, Carol marries Jefferson and Ginevra marries Dr. Gerard.

The 1930's were the golden age of Nile River cruising.  Diplomats, businessmen and archeologists paid to ride on boats like the S. S. Sudan.  In 1933, Author Agatha Christie, along with her archeologist husband, took this boat.  Refined ladies with parasols and gentlemen with pipes would stroll its decks.  Fine Egyptian cuisine was served in the charming dining room.  The wooden panelling, gilded and copper bed frames and parquet floors in the cabins kept the passengers coming back. The five day cruise aboard the S. S. Sudan, still running today, follows the Nile River from Luxor in the north, to Aswan in the south.  Highlights include the Giza Pyramids and the Sphinx.  The ship boasts 15 cabins and 8 suites, including the Agatha Christie Suite and Hercule Poirot Suite. It was here that the bestselling novelist penned her famous book Death on the Nile.

Dumb Witness

Emily Arundell writes to Hercule Poirot complaining that someone is trying to kill her.  She fell down the stairs, an accident attributed to her fox terrier's rubber ball.  However, by the time Poirot receives her letter, she is dead.

Emily's doctor says she died of chronic liver problems.  Emily's companion, Minnie Lawson inherits the deceased's house and fortune.  In a previous will, the inheritors would have been Emily's nephew, Charles, and nieces, Theresa and Bella.  Upon investigation, Poirot discovers a nail with varnish and a string attached to it at the top of the stairs.  "Bob...dog...picture...ajar." had been the message that Emily had given before her death.  Poirot concludes that Bob the dog, who was outside that night, did not leave the ball on the stairs and that Emily was tripped by the string.

Emily's nephew and nieces talk about contesting the will, but it is not pursued.  The gardener reveals that the nephew, Charles, talked to him about his arsenic based week killer.  The bottle is almost empty.  Minnie Lawson says that on the night of Emily's death she saw someone through her bedroom window wearing a broach with the initials T.A. (possibly Theresa Arundell, Emily's niece).

IN the meantime, Bella reveals her husband Jacob is bullying her and she moves with her children to a hotel, with the help of Minnie.  However, for more security Poirot recommends she moves to another hotel.  The next day Bella is found dead due to an overdose of chloral, a sleep aid.

Poirot reveals his theory on the murders.  Theresa stole the arsenic but could not bring herself to use it.  She and her brother suspected each other.  Emily, fearing that Charles might be trying to kill her, revealed that she had revised her will.  He was satisfied with just stealing some of her money.  The brooch which Minnie had seen was really Bella's.  The initials TA, reversed in the mirror, stood for Arabella Tanios.  She hated her husband and wanted to separate from him and keep the children, but she had no means to do so.  Her first attempt with the ball and string failed.  Her second attempt involved inserting elemental phosphorous in one of Emily's liver capsules, which succeeded.

Emily was unaware that her aunt had revised her will.  When Poirot explained the murder, she took her own life and her children went back to their father.  Emily's husband is upset as he did love his wife.  However, he finds out she obtained the chloral to kill him.  Minnie decides to share her wealth with Charles, Theresa and Bella's children.  Theresa marries Dr. Donaldson,  Charles squanders his wealth.  The terrier goes to live with Poirot but he prefers Captain Hastings.

ABC Murders

Poirot receives typed letters from a serial murderer, ABC, explaining where and when the next murder will be.   Alice Ascher is a tobacco shop owner killed in Andover.  Betty Barnard is a flirtatious waitress killed in Bexhill.  Carmichael Clarke is a wealthy man killed in his manor in Churston.  ABC leaves a railway guide with each victim.  Poirot wonders:  "Why would ABC write to him instead of Scotland Yard or any reputed newspaper?" and "Why did a meticulous man like ABC misspell Poirot's address on the Churston letter?"

The murder mystery is unravelled by Captain Hastings who talks about Cust, travelling salesman and Great War veteran, who suffered from epilepsy due to a war injury.  He is prone to memory blackouts and headaches.  Also involved in the investigation are Inspector Crome, who doubts Poirot's investigative abilities, and Dr. Thomson who profiles the serial killer.

Poirot notices a similarity among all three murders.  A stockings salesman visited each home before the murder, selling a pair of stockings to the first two victims, but being turned away by the third.  ABC sends a fourth letter, this time directing everyone to Doncaster where a famous horse race will take place.  But ABC strikes in a cinema where he kills George Earlsfield, instead of Roger Downes, the logical victim sitting only two seats away.  The salesman, Cust, who had suffered a blackout, later slips out of the theatre unnoticed.  Cust finds the murder weapon in his pocket and blood on his sleeve.

Cust, tipped off that the police are after him, flees but collapses at the Andover police station.  Cust, who can't remember the murder, fears that he is guilty.  Cust's room contains many incriminating items:  silk stockings, lists of clients, the fine paper used to type the letters to Poirot, an unopened box of ABC railway guides, and in the hall lies the bloodied knife from the most recent murder.  It is revealed that Cust was never hired by the stocking company and that the letters to Poirot were indeed typed on Cust's typewriter, the one he claimed the company gave him.  Poirot meets with Cust who has no recollection of any of the murders.  He has a solid alibi, however, for the Bexhill murder.

Poirot categorically explains how Cust could not have committed the murders.  Then he points the finger at Franklin Clarke, the brother of Sir Carmichael Clarke, the third victim.  Sir Carmichael was heir to a fortune and a member of Cust's legion.  The third letter, which contained an error, was meant to lead the reader astray.  Franklin had feared that, with Lady Clarke's death imminent, his brother would marry his young beautiful assistant.  When Sir Carmichael died, his wealth would go to his new wife and any children they had.  Franklin's meeting with Cust in a pub served as inspiration for his serial murder plot, with Cust serving as the stalking horse.

Franklin laughs off the accusations until Poirot states that the former's fingerprint was found on Cust's typewriter key.  Further Franklin has been recognized by Milly Higley, a coworker of the deceased Betty Barnard.  Franklin tries to shoot himself but Poirot is one step ahead of him and has emptied the bullets from his gun.  Poirot reveals to Hastings that the fingerprint on the typewriter key was a bluff.  Cust, meanwhile, has an offer from the press to sell his story,

Three Act Tragedy

At a party in Cornwall, the mild-mannered minister, Reverend Stephen Babbington, chokes on his cocktail, goes into convulsions and dies.  Investigation of the glass finds no poison.  Hercule Poirot is baffled; there appears to be no motive.  The party, hosted by Sir Charles Cartwright, also included:  Dr. Strange, Lady Mary Lytton Gore and her daughter Hermione, Captain Dacres and his wife Cynthia, Muriel Wills,Oliver Manders, Mr. Satterthwaite, and Mrs. Babbington.  Sir Charles mixed the drinks.

Another party is hosted in Yorkshire with many of the same guests, except Sir Charles, Mr. Satterthwaite and Poirot.  Oliver Sanders' motorcycle breaks down right in front of the manor. Sir Charles new butler serves port to all of the guests.  Dr. Strange collapses and dies.  His glass is tested and it is determined he died of nicotine poisoning.  Reverend Babbington's exhumed body reveals the same substance.

Mr. Satterthwaite and Sir Charles investigate the two deaths.  It turns out Dr. Strange gave his usual butler a vacation just two weeks before his death.  After his murder, his temporary butler disappeared.  In Ellis' room papers are found indicating he was blackmailing Dr. Strange.

Poirot receives a telegram from Mrs. D at the sanitarium.  Later, Mrs. D is discovered murdered as a result of nicotine poisoning.

It turns out that Sir Charles murdered all three victims. Charles had wanted to marry Hermione but couldn't because he had a wife in the insane asylum.  British law forbade him from divorcing her.  He murdered Dr. Strange who was the one person who knew about his wife.  The Cornwall party was a dress rehearsal for the real murder.  Reverend Babbington was the guinea pig.  Sir Charles managed to switch Babbington's tainted glass with an untainted one.

Sir Charles then convinced Dr. Strange to let him play the role of the butler.  When Muriel spoke up, Sir Charles was prepared to kill her too.  However, Poirot told her to go into hiding.  Mrs. D was silenced because otherwise she would have told Poirot she did not send the telegram and was unconnected to the crime. Sir Charles is arrested and Hermione matches up with Oliver Manders.

Why Didn't They Ask Evans?

While playing a round of golf with his friend Dr. Thomas, Bobby Evans swings his golf ball over a cliff.  At the bottom of the precipice he finds the crumpled body of man whose last words are;  "Why didn't they ask Evans?"  Bobby finds a photograph of a beautiful woman in the dead man's pocket, but without identification.  Another man who comes upon the scene, Roger Bassington-French, offers to stay with the body while Bobby leaves to play the organ at his father's church.  The dead man is identified as Alex Pritchard and the beautiful woman in the photo is his sister Amelia Cayman.

Bobby rejects a job offer from Buenos Aires.  In the meantime he drinks from a poisoned beer bottle.  Bobby discovers that Amelia Cayman is an imposter.  He figures that the stranger at the scene of the crime must have switched the photo in the dead man's wallet.  Bobbie and his friend Frankie search for Bassington-French and find an address in Hampshire.  There, they stage a car accident hoping that Frankie, injured, will be invited into the home.  Inside, Frankie meets Roger's brother, Henryk, and sister in law Sylvia.  Frankie shows the couple a newspaper clipping of the dead man.  Sylvia says he resembles a man who was good friends with a big game hunter, Alan Carstairs, who killed himself after being diagnosed with terminal cancer.

Frankie meets Henry and Sylvia's neighbours, Dr. and Moira Nicholson, who run a sanitarium.  Bobby investigates the sanitarium where he runs into the beautiful woman from the photo.  Moira turns up at the local inn where Bobby is staying and says her husband is trying to kill her.  Frankie asks Roger if he took the photo of the beautiful woman and he admits that he dead, wanting to avoid scandal for her.  In the meantime, Henry is found dead in his home, an apparent suicide.

Frankie asks a solicitor about Savage's will and finds out that he was staying with Mr. and Mrs. Templeton when he first discovered he had cancer.  One specialist, however, said he was perfectly fine.  When he died, he left 700,000 pounds to the Templeton's.  Bobby is kidnapped and Frankie is lured, along with Roger, to an isolated cottage.  Badger Beadon arrives to find a drugged Moira in the cottage.  When the police appear on the scene, Roger has vanished.

They trace the witnesses to the signing of John Savage's will.  They are the former cook and gardener of Mr.and Mrs. Templeton.  The parlourmaid, Gladys, however, was not asked to witness the singing of the will.  In reality, it was not John Savage who signed the document but Roger Bassington-French.  Gladys' last name is Evans, hence the dying man's question:  "Why didn't they ask Evans?" Gladys is now the housekeeper at Bobby's home and the dying man was trying to find her.  

Returning to Wales, they find Moira who claims she is being followed by Roger.  Frankie, suspicious of Moira, spoils the latter's attempt to poison their coffee.  It turns out Moira was really Mrs. Templeton and Roger's accomplice.  Moira attempts to shoot Bobby and Frankie but is overpowered.  Weeks later Frankie received a letter postmarked South America from Roger who admits that he murdered Carstairs and his brother Henry.  Frankie and Bobby get engaged.

Lord Edgware Dies

Actress Jane Wilkinson asked Poirot to convince her husband Lord Edgware to agree to a divorce.  Poirot speaks to Lord Edgware who says he has already written a letter to his wife to that effect.  That evening, Lord Edgware is found dead in his study.  The newspaper reports the next morning that Jane was at a prominent party the previous night.

Inspector Japp informs Poirot of the murder.  It turns out that Jane arrived at Regent Park the night before, announced herself to the butler and was spotted entering her husband's study by the secretary. The prominent dinner party had thirteen guests.  One guest pointed out that a table of thirteen meant bad luck for the first one to rise.  Jane was the first to get up to answer a telephone call.

In the meantime, Carlotta Adams, who liked to do impersonations of Jane, is found dead from an overdose of Veronal.  The butler, along with some money, disappeared on the day of Lord Edgware's death.  Ross is suspicious of Jane when he discovers she demonstrates an unusual amount of knowledge of Paris of Troy.  He phones Poirot to tell him of his suspicions and while on the phone, he is murdered.

Poirot tries to piece together the three murders.  He believes that Carlotta Adams impersonated Jane at the dinner party enabling Jane to take a taxi to Regent Park and murder her husband.  Carlotta and Jane meet up later where Jane has promised her money for her impersonation, but gives her a fatal dose of Veronal instead.  Jane then planted a case with Verona in it on Carlotta's person to make it seem like she was addicted to the drug.  Jane, knowing that Ross was a risk as he pursued Poirot, murdered him.  Jane's motive for killing her husband was that she wanted to marry the Duke of Merton.  The Duke was a Roman Catholic who was permitted to marry a widow but not a divorcee.

Giant's Bread

London's new opera house celebrates its grand opening with a new opera called The Giant.  Carl Bowerman, a distinguished and elderly art critic, does not like the new opera.  He joins the opera house owner, Sebastien Levinne, for a drink.  Bowerman points out that Boris Groen, the composer of the opera, has a similar style to Vernone Deyre, a composer who was killed in the First World War.

Vernon, who grew up in the Victorian era, was the son of a soldier father, Walter, and an emotionally clingy mother.  He was raised largely by his nurse.  While Vernon had no friends, he had four imaginary friends who lived on the grounds, the most important of which was Mr. Green.  Vernon's Uncle Sydney, who has a manufacturing business in Birmingham, makes him feel uncomfortable while Walter's sister, who plays the grand piano in his house, gives him a good feeling.  

Aunt Ninas marriage breaks up making her a single mom to Josephine.  In the meantime, Walter goes off to fight in the Boer War.  Aunt Nina dies and Myra takes in Josephine to the delight of Vernon who now has a playmate.  A new family comes to town named Levinne who are held in disdain because they are Jewish.  However, in time the Levinne's are accepted by the locals.  Vernon and Josephine make good friends with their son, Sebastien.  

In the meantime, Walter is killed in action and Vernon is set to inherit the family estate when he comes of age.  Myra and Josephine, short on money, move to Birminghamm to be close to Uncle Sydney.  Elven years pass in which Vernon and Sebastien remain friends.  Sebastien's father dies and he inherits millions, but Vernon continues to be short on money.  He goes to work at Uncle Sydney's manufacturing firm.  In the meantime, he is invited to a charity concert at Albert where he has a life changing moment:  he starts to love music and decides to become a composer.

Vernon meets up with Nell Vereker, an old school chum from Cambridge, and they fall in love.  However, both Nell's mother and Vernon's Uncle Sydney think that he is not rich enough for Nell and convince him to postpone marriage.  In the meantime, Vernon starts seeing a woman ten years his senior named Jane who encourages him to pursue his music and quit the manufacturing firm.  Vernon's bites the bullet and proposes to Nell who, to spite him, runs off and gets engaged to another man.  Vernon in turn runs into the arms of Jane.  

Four days after the outbreak of World War I, Nell and Vernon meet again and she admits that she is still in love with him.  They are married later that afternoon after she finds out that Nell has enlisted.  Six months later, Vernon goes off to war and Nell becomes a VAD nurse.  However, later she finds out that Vernon has been killed in action.  As his widow she inherits his estate and sells the property.  Her former flame, George, buys it, proposes marriage and she accepts.

In neutral Holland in 1917, Vernon has escaped from a German prisoner of war camp.  He reads a magazine and discovers that Nell has remarried.  Despondent, he throws himself in the path of an oncoming truck.  He survives, but suffers amnesia.   Vernon becomes a chauffeur and meets a wealthy American who is visiting England.  The American introduces him to a friend who in turn leads him to his wife, Nell.  She gets him professional help and he declares he wants to get back together.  Nell, frightened, lies and says she is pregnant by George.

In the meantime, Vernon and Jane reunite and travel to Russia where he is taken by the avant-garde music.  A telegram from New York stating that Josephine is gravely ill sends them sailing across the Atlantic.  The ship, hit by an iceberg, starts to sink.  In the commotion, Vernon spots Nell who begs him to save her.  Vernon grabs Nell as Jane, with a horrified look on her face, goes "down into that green swirl."  In New York, Vernon confesses to Sebastian that he let the love of his life drown.  Torn by emotion, he puts his heart and soul into a composition and the result is The Giant.

In the morning, despite all of the alarm clocks having rung, Gerry has not risen.  He is found dead in his bed of a chloral overdose.  Tow of the young men, Jimmy and Ronny, drive over to Gerry's stepsister, Loraine's, house to break the bad news.  They return to Chimneys where they search Gerry's room and find only seven alarm clocks.  The missing one is found in the bushes at Chimneys.

Lord Caterham retakes possession of Chimneys.  His daughter, Lady Eileen "Bundle" Brent, puzzled about the crime, writes a letter to Bill Eversleigh.  It turns out that Gerry died in her bedroom.  In her writing desk she finds an unfinished letter from Gerry to Loraine.  In it, he states:  "Forget what I said about the Seven Dials business."  She decides to visit Bill in London.  On the way, a stranger jumps out of the bushes in front of her car.  She gets out as the stranger collapses to the ground, muttering "Seven dials...Jimmy Thesiger."  Bundle manages to get him in her car and take him to the doctor where he's pronounced dead-- not from Bundle's car but from a gunshot wound.

The dead man is identified as Ronny, one of the young men at the party.  IN the meantime, George Lomax receives a warning letter from the Seven Dials district of London.  Bundles gets Jimmy's address in London and goes to break the news to him.  Loraine is also present.  Jimmy and Loraine reveal Ronny could have had ties to the Mafia.  Loraine says that she discovered a list of names and dates together with an adress in Seven Dials.  The three wonder if the missing alarm clock, leaving seven alarm clocks, was a warning left by the killer.

Bundle discovers that the Seven Dials is a seedy nightclub.  She begs Bill to take her there.  At the club, she recognizes the doorman as the former footman at Chimneys.  She questions the doorman who tells her that a Russian named Mosgorovsky offered him three times the pay to work at the nightclub.  Mosgorovsky also supplied a replacement for the footman, a man named John Bauer.  The doorman shows Bundle a secret room with seven chairs.  Bundle hides in a closet and eavesdrops on a meeting among seven people, all with white hoods with slits and clock faces.  One member of the group talks about the upcoming party at Wyvern Abbey where a German named Everhard will be there with a new invention.

Bundle later learns that the invention is one that makes wire as strong as steel.  Everhard is about to present the invention to the British at the party.  Bundle and Jimmy wrangle invitations to the party where the find Superintendent Battle disguised as a waiter.  Jimmy goes to the library to check something out.  Bundle is told to stay in her room, but sneaks out the window and down the trellis to be a part of the action.  Looking for Jimmy she hears a scuffle on the balcony outside the library and two gunshots.

Battle runs to the library where he finds Jimmy wounded and unconscious.  Sir Stanley runs to his room where he finds the invention formula missing.  Sir Oswald Coote arrives saying he was on a walk and discovered the gun.  The next morning Battle searches the crime scene and finds one set of footprints leading up to where the gun was discovered -- Sir Oswald Coote's.  He also finds a charred glove with teeth marks in the fireplace.  Jimmy gets closer to Lady Coote's and receives an invitation from Lady Coote to their new house in Letherbury where he hopes to investigate Sir Oswald Coote.

Jimmy rings up Bundle and Loraine and tells them to meet him and Bill at the Seven Dials Club.  Jimmy arrives, having left Bill in the car.  Bundle shows him the secret room.  In the meantime, Bill is knocked unconscious in the car.  Bundle goes looking for brandy for Bill and is also knocked out.  Mogorsky takes them to a meeting of the Seven Dials where the identity of Number 7 is revealed;  it's Superintendent Battle.  The Seven Dials is a secret group of criminal catcher and included Gerry Wade and Ronny Devereux.

It turns out that the secret formulae thief was Jimmy Thesiger, along with his accomplice Loraine, both of whom have just been arrested.  Ronny was killed when he got too close to the truth.  HIs last words were a warning to the Seven Dials about Jimmy, not the other way around.  Jimmy climbed on the ivy and threw the stolen formula down to Loraine.  He staged a fight in the library where he shot himself in the right arm.  His right arm being disabled, he had to use his teeth to pull off his glove which he tossed in the fireplace.

The police suspect that Ruth's lover, Comte de la Roche is guilty of her murder, but Poirot suspects otherwise.  The detective suspects Derek Kettering, Ruth's husband, who is on board but claims he hasn't seen his wife.  A cigarette case inscribed with the letter K found in the dead woman's compartment casts further doubt on Derek.  When Poirot discovers that the famous jewel thief Le Marquis is on board, he realizes that the murder and the jewel theft may not be linked.

The dancer Mireille, on the train with Derek, reveals that she saw him leave Ruth's compartment around the time of the murder.  Derek is arrested but Poirot remains unconvinced.  He asks Van Alden and Knighton to come on the train with him to recreate the murder.  Knighton is really Le Marquis, the jewel thief, but no one suspected him since he was supposed to be in Paris at the time of the murder.  It turns out that the K on the cigarette case stands for Knighton, not Kettering.

The Murder of Roger Ackroyd

In the town of King's Abbott, a woman named Mrs. Ferrars commits suicide after she can't bear the guilt she feels at poisoning her husband the previous year.  Roger Ackroyd, the town's wealthiest citizen, was expected to marry Mrs. Ferrars.  He invites Dr. Sheppard to dinner, claiming he has something important to tell him.  He also invites Mrs. Cecil  Ackroyd, his sister in law, Miss Flora Ackroyd, his niece, Geoffrey Raymond, Ackroyd's young secretary, and Major Blunt, Ackroyd's friend.  Visibly distraught during dinner, Ackroyd has a private conversation with Dr. Sheppard after dinner revealing that Mrs. Ferrars killed her husband and was being blackmailed for the murder.  At that moment, a letter arrives from the late Mrs. Ferrars which states who the blackmailer is and how she hopes Mr. Ackroyd will seek revenge on him.  Mr. Ackroyd choses not to name the blackmailer.

Dr. Sheppard leaves Fernly Park (Ackroyd's estate) and on the way home bumps into a stranger who asked for directions to Ackroyd's residence.  At home he receives a phonne call from Fernly Park saying that Ackroyd was murdered.  THe next day, Flora Ackroyd suggests to Dr. Sheppard that they recruit Hercule Poirot, the doctor's new neighbour, to solve the murder.  Flora is worried that Ralph Paton will be blamed for the crime since he was spotted at Fernly Park and that footprints matching a pari of shoes owned by Paton were found in the dirt outside Ackroyd's study the night before.  Paton, who was in a lot of debt, expected to inherit a large amount of money upon Ackroyd's death.  Dr. Sheppard points out that after he left Ackroyd's study at 9:30 pm and before the body was found at 10:30 pm, Major Blunt and Geoffrey Raymond overheard someone speaking to Ackroyd in his study.

WHile the police are convinced that Paton is the murderer, Poirot has his own theory.  He fixates on a phone call made to Dr. Sheppard from the King's Abbott train station and on a grandfather chair which was moved into the middle of the study when Ackroyd was discovered.  Poirot assembles Mr.s Cecil Ackroyd, Miss Flora Akroyd, Major Blunt and Geoffrey Raymond together and accuses them all of hiding something.  Mrs. Cecil Ackroyd and Raymond admit that they owed Ackroyd money and his death resolved them of all debts.  It turns out that Parker, Ackroyd's employee, was guilty of nothing more than snooping.  He had heard about blackmailing and thought that maybe he could get in on the act and blackmail his boss.  It turns out that Flora lied about wishing her uncle good night on the night in questions.  She sneaked up to his room to steal money to settle some debts of her own.  Ackroyd's housekeeper Miss Russell explaing that Charles Kent, the stranger found on the grounds that night, cannot be the murderer.  She met Kent, her illegitimate son, at Ackroyd's summer house that night.

Poirot determines that Ackroyd purchased a Dictaphone the week before the murder and therefore that was what people overheard at 9:30 pm on the night of the murder.  He also reveals that Dr. Sheppard had been hiding Ralph Paton by pretending he was a patient in the local insane asylum.  Poirot declares that Dr. Sheppard is the murderer.  He murdered Ackroyd and then programmed the Dictaphone to go off at 9:30 pm.  In the meantime he planted the footprints using Paton's shoes.  He hid Paton so that he would look more suspicious.  Dr. Sheppard's motive was the fact that he was Mrs. Ferrars' blackmailer.
