Nobody mentioned the victims, or the terror that had gripped the town. For the last twenty days it had rained and between the usual quiet conversations and card games, only the trickle of water and the air of cold fear could be detected. A serial killer stalks La Rochelle's cobbled streets - and by the most unfortunate of occurrences, Kachoudas, a poor timid tailor and a newcomer to the town, knows exactly who it is... One of Georges Simenon's darkest novels, The Hatter's Ghosts is a riveting portrait of murder and subterfuge, at once a cat and mouse thriller and an acute physiological study of the criminal imagination.
