Nick comes across the final pages of Catherine's book in which the fictional detective finds his partner's body in an elevator. Catherine then breaks off their affair, causing Nick to become upset and suspicious. Nick later meets his partner Gus Moran, who has arranged to meet with Catherine's college roommate at an office building, hoping to reveal what really went on between Catherine and Beth. As Nick waits in the car, Gus is stabbed to death with an ice pick in the elevator. Recalling the last pages of Catherine's book, Nick runs into the building, only to find Gus' body in a manner similar to the scene described. Beth unexpectedly arrives and explains that she received a message to meet Gus. Nick suspects Beth has murdered Gus and, believing that she is reaching for a gun, shoots her, but discovers that Beth was only fingering an ornament on her key chain.
