"Booby Trap," one of the first Nero Wolfe novella-length stories, was first published in The American Magazine. It is the second of the two stories that feature Archie, Wolfe's live-in employee in all others stories, as Major Goodwin for the US Army Intelligence. In this, a grenade is used to create a lethal booby trap for an army colonel. "Booby Trap" is vintage Wolfe. It has everything his fans expect of their beloved character: beer, orchids, colorful exchanges with Archie, love (a woman in the brownstone), Wolfe leaving the house, Wolfe riding in a car, and Wolfe attempting to sit in an unsatisfactory chair.
