Roman de Gare

Claude Lelouch's thriller Roman de Gare (aka Crossed Tracks) features a number of characters and a timeline that skips back and forth, keeping the audience guessing as to how these characters all relate to each other. Fanny Ardant plays a novelist named Judith whose famous works might have been ghost-written by a serial killer dubbed "The Magician" for his habit of performing acts of prestidigitation in front of his victims. Early in the film, the police quiz her about her relationship with the criminal. Other characters include a hairdresser (Audrey Dana) who offers to give a ride to a stranger who may be the killer.
