Superintendent Maigret arrives in the small fenland town of Saint-Aubin-les-Marais after being asked by a friend to help a man accused of murder, only to meet with hostility and silence from the townspeople.
Matters are not improved when he encounters an unpleasant former colleague nicknamed Cadaver, sacked from the police force for corruption and now working as a private sleuth. Cadaver seems to be doing everything in his power to obstruct Maigret's investigations, but who has employed him? Maigret soon finds himself involved in a case that may ruin the very people he has come to help . . .
Told in Simenon's spare, unsentimental prose, Inspector Cadaver is a haunting exploration of provincial hypocrisy and snobbery.
