Maigret is called to the home of professional gambler Felix Nahour, who has been found shot dead by his chambermaid. Maigret is shocked to recognise a photo of the man's wife, who becomes the main suspect. All signs point to her guilt, but Maigret suspects there might be more to this complicated affair.
