The small French town of Concarneau is a summer resort. In winter it becomes the deserted, rain swept scene for a series of murder attempts that attract the interest of Maigret. While his assistant Leroy uses "science" and "deductions" to trace the murderer, Maigret's instincts unerringly guide him to the real killer past a labyrinth of fascinating characters: a paranoid failed medical doctor turned real-estate shark; a passive, working class waitress whose heart secretly burns a torch of passion; an aristocratic politician who pressures Maigret to "make some arrests"; and a snarling stray dog that knows the murderer's real identity.
