Zigoto et l'affaire du collier

The film begins with the Count giving an actress a necklace. However, after her performance, the valuable necklace is missing and so the actress goes to hire some detectives to find it. I loved the strange detective agency in the film. The place had a sliding door, chains on the wall and detectives seem to magically appear out of the floor. It was very kooky but fun. (imdb)
