Synopsis of Murder Is No Joke
Alec Gallant was a member of the French Resistance during World War II and at that time married another member, Bianca.
After the war, he learned that his wife and her two brothers had been traitors to the Resistance. He murdered both men, but Bianca escaped him.
Gallant came to the United States in 1945 and rejoined his sister Flora, and became a highly regarded couturier.
Then comes Bianca. She has changed her surname to Voss and insinuated herself into Gallant’s operation, making decisions about company strategy, apparently with Gallant’s approval.
Everyone is mystified that Gallant is putting up with Bianca’s odd and counterproductive decisions, particularly because she seems to have no formal title or position at the company.
Fearing for her brother’s career, Flora, who ignores the relationship between Alec and Bianca, calls at Nero Wolfe’s office and asks him to investigate the situation.
Flora suggests that they phone Bianca, and invite her to Wolfe’s office where he can ask questions of her, and then, «We shall see.»
Flora uses Archie’s phone to call Miss Voss, and gives Archie the handset as Wolfe picks up his own phone.
After identifying himself to Miss Voss, Wolfe becomes the target of a string of insults hurled by Miss Voss. Then they hear a thud, a groan, a crash, and a dead phone line.
Archie calls Gallant’s offices back and learn that Miss Voss has just been found dead in her office.
When they inform Flora, she seems stunned, and hurries from the office.
