A hatter in a provincial town (Michel Serrault) leads the life of a respectable citizen but is in fact a serial murderer. The only person to suspect this is his neighbour the tailor (Charles Asnavour).
The Hatter's Ghost is a 1982 French crime film directed by Claude Chabrol. It is based on the 1947 story Le Petit Tailleur et le Chapelier by Georges Simenon. It takes place in Brittany and was shot in the towns of Concarneau and Quimper.
