Maigret at the Gai-Moulin
 Jean Chabot and René Delfrosse plan to hide in the cellar and rob the till at the Liege nightclub, Gai-Moulin. After the nightclub closes for the night, they venture out of the cellar and stumble on the body of a Greek man. Frightened and in shock they run away from the nightclub. Jean, who has been taking money from the petty cash at the office where he works, needs to return the money before the books are closed and so René steals cash from the till at his uncle's chocolate shop. When they find that they are being followed, they decide to throw the money down the toilet but Jean is arrested before he can do that. He insists he is innocent but the stories of Adèle, a dancer at the Gai-Moulin, Victor, a waiter at the Gai-Moulin, and Gennaro, the proprietor all seem to point at the guilt of the two boys. However, some suspicion also centers on a Frenchman who arrived in Leige on the same train, was staying at the same hotel as the murdered man, and who was at the Gai-Moulin at the same time. Inspector Delvigne does not know what to think when Maigret makes a surprising appearance on the scene.
