Whilst moving into her new Paris apartment, Madame Dumont discovers a dead body in her wardrobe. Soon more corpses pile up near the metro station Picpus and the eponymous street: a clairvoyant, a blind man, a doctor, a real estate agent. These people have certainly got something in common, but what can it be? Maigret is summoned to investigate in this thrilling whodunit from director Richard Pottier (Fanfare d'Amour).
