Trouble in Triplicate tells a trio of tales in which the murder victim comes to Wolfe before being killed. In "Before I Die" a crime boss brings a blackmail case to Wolfe, never expecting to die. But just in case, he makes Wolfe the executor of his estate, thereby making Wolfe and Archie Goodwin the prime suspects in his murder. Wolfe's task: solve the crime boss's murder before he and Archie are erased by the boss's vengeful hit man. In "Help Wanted--Male" Wolfe blows off a prospective client who has received a death threat mere hours before the man's brutal murder.
