Dédé

In Jeux de glaces, the TV film adaptation of Agatha Christie's They do it with Mirrors by France Télévisions, Dédé is an inmate of "La Main Tendue", the rehabilitation centre run by Etienne Bousquet and his wife. Early in the episode, another inmate, Marcel, had been found dead with his throat slit. Dédé is seen sitting by the body with blood on his hands. It seemed obvious to everyone that Dédé is the killer. However Commissaire Swan Laurence, who arrives on the scene, clears him. He notes that Marcel had been killed by someone who is left-handed whereas Dédé is right-handed. Etienne Bousquet tells the police that Dédé is a gentle creature and prison would destroy him.

The character of Dédé is played by Jean-Marie Paris. There is no parallel character to him in the original novel.
