Meanwhile, Mr. Whiteside's spinster assistant Maggie, played by Bette Davis, finds herself attracted to local newspaperman Bert Jefferson (Richard Travis). Maggie announces she is going to marry Bert, but Mr. Whiteside realizes he can't lose her, and thus tries sabotaging the relationship. Mr. Whiteside exaggerates the extent of his injury in order to remain longer at the Ohio home. He suggests that Lorraine Sheldon would be a perfect co-star in a play hoping she will steal Bert Jefferson away from Maggie.

Maggie, catching on to the conniving Mr. Whiteside, quits her job. Mr. Whiteside tries to get Lorraine out of the picture by trapping her in an Egyptian sarcophagus and shipping her off to Nova Scotia. Finally, the Ohio homeowner, realizing Mr. Whiteside is faking his injuries, orders him to leave. But as he walks down the steps, he slips again on the ice and goes back into the house to convalesce.
