If Death Ever Slept is a Nero Wolfe detective novel by Rex Stout, published by the Viking Press in 1957 and collected in the omnibus volume Three Trumps (Viking 1973). Plot introduction Millionaire Otis Jarrell retains Nero Wolfe to get a snake out of his house – the snake being his daughter-in-law, whom he believes is ruining his business deals by leaking information to his competitors. Since Archie and Wolfe are in the midst of one of their periodic squabbles, it is decided that Archie will move into Jarrell's Fifth Avenue penthouse apartment, posing as his new secretary. While he's away, detective Orrie Cather, who lusts after Archie's job, tests out Archie's desk. Plot Millionaire Otis Jarrell offers to hire Wolfe to get his daughter-in-law Susan out of his house. He is convinced that she has ruined several of his business deals by leaking confidential information to his competitors, and he suspects her of infidelity toward his son Wyman. Wolfe refuses to get involved in what he sees as a marital disagreement, but accepts a $10,000 retainer from Jarrell to hire Archie as a live-in secretary. Taking the alias "Alan Green," Archie is to replace the previous secretary, whom Jarrell had fired one week earlier on suspicion of being the source of the leak. Arriving at the Jarrell penthouse on the following Monday, Archie meets the rest of the family and associates, including Jarrell's wife Trella; his grown children, Wyman and Lois; Wyman's wife Susan; Trella's brother, Roger Foote; and Jarrell's stenographer, Nora Kent. Over the course of the week, Archie learns from Trella that Jarrell had made a pass at Susan but was rejected; he also encounters James L. Eber, Jarrell's former secretary, having a private conversation with Susan. Nora explains that he had visited the penthouse in order to retrieve some papers from his desk. Shortly after Archie sees Eber, Jarrell discovers that someone has sneaked into his library and stolen a .38 revolver from his desk, holding up a rug to foil a security camera at the doorway. Jarrell believes that Susan is responsible for the theft, but Archie reports to Wolfe the next day and is dispatched to investigate Eber's apartment. There he finds Eber's body, shot in the head; news of the murder reaches Jarrell the following morning, throwing him into a panic that the police may begin digging into his private affairs.
