Maigret's Pickpocket (Inspector Maigret Book 66)

When Inspector Maigret's wallet and badge are stolen on a bus, it sets off a chain of events culminating in a grisly murder case

A pickpocket steals Maigret's wallet only to contact him the following day, returning the stolen items on the condition that he come to the thief's apartment. When the agitated young thief leads Maigret to the body of his wife, dead of a gunshot wound to the head, he implores Maigret to take the case. Unsure whether he can trust him, the inspector becomes embroiled in a most unusual murder investigation.

Putting the detective's knowledge of Paris's underworld to the test, Maigret's Pickpocket is a shocking mystery from Georges Simenon.
