Les vampires: L'évasion du mort

The examining magistrate from Saint-Clement-Sur-Cher relocates to Paris and is assigned to the Vampire case and the Moréno affair. After being summoned to the magistrate, Moréno commits suicide using a concealed cyanide capsule. His body is left in his cell, but during the night he wakes up, very much alive. He kills the night-watchman and takes his clothes, escaping from the prison. He is noticed by Mazamette, who is suffering from insomnia. (wikipedia)
