John Bently stars as detective Paul Temple and Patricia Dainton is Steve, his wife.
A serial killer known as "The Marquis" is terrorizing London and the police are having a time solving the case. Scotland Yard warns Temple to stay out of the case, but he and his wife get involved anyway.
This was originally known as "Paul Temple Returns" but the title was changed as Americans had no idea who Paul Temple was. It is a standard mystery film with all of the usual trappings, but it does move along well, and the actors know their roles.
Christopher Lee has a role in the film as Sir Felix Raybourne, and one could tell in this early role he was going to be a huge star. I liked the flavor of the British scenery and I always find film noir from England to be very entertaining, albiet different.
It's a rare film and if you like mysteries I think you'll enjoy this.
