It's closing time at the Gai Moulin, and Jean Chabot and Rene Delfrosse are planning to rob the till to pay of their debts. To their surprise, they stumble upon a dead body. What at first seems to the police an open and shut case proves more complicated when the body turns up next at the zoo, stuffed into a wicker basket. Into the puzzlement steps Maigret, who makes one of the most dramatic and colorful entrances of his career as he sorts out the tangled web of deceit.
