is a 1960 black-and-white British thriller film directed by Val Guest and starring Claude Dauphin, Diane Cilento and Ronald Lewis.

English racing driver Alan Colby and his wife Denise were involved in a bad accident a year ago.

Alan confesses all of the details of his fantasy, which includes strangling Denise in bed, dismembering her body and dropping the pieces down a disposal chute in their apartment building.

After many sessions, Prade concludes that Alan believed that he had killed Denise at the moment of the crash and has been reliving those feelings ever since.

Prade pieces together clues, all of which resemble Alan's murderous fantasy, and they fear that he has killed Denise while in a psychotic fugue state.

However, Denise finds an estimate for repairs to Prade's car and realizes that he slaughtered his own cat in order to stage the murder scene to deceive Alan.

[3] In a contemporary review for The New York Times, critic Howard Thompson called the film "a snug, tautly-strung little thriller" and wrote: "[T]he dialogue has a nice, cutting edge, the tempo and photography are crisp and the picture seems ready to slope off in suspenseful familiarity.

After the best scene of all (a carbolic couch session, where the camera, from the patient's viewpoint, restlessly whips around the doctor's office), the story flip flops to a surprising new plane.
