Maigret und sein Revolver

During an unusual call at the police station, Madame Maigret informs her husband that a young man is waiting for him at home. However, when Maigret arrives, the visitor is gone, and a sensitive item is missing: Maigret's revolver. Shortly thereafter, a body is discovered at Gare du Nord. Now, the task is not only to solve a murder but also to prevent another one – so the inspector follows the trail of his revolver all the way to the prestigious Savoy Hotel in London.
