Maigret and the Saturday Caller

Leonard Planchon, a tense man with a harelip, goes to Maigret with an unusual problem. He wants to kill his wife, or perhaps his wife and her lover, who for two years now have been making him sleep on a cot in the dining room. He has even worked out a plan to hide their bodies in concrete. Uneasily investigating a murder that has not yet been committed, Maigret explores the bistros of Montmartre and uncovers a peculiar—and pathetic—menage a trois.
