Blood Orange (aka Three Stops to Murder) (1953)

In Terence Fisher’s elegant British crime mystery, a fashion designer becomes entangled in blackmail and murder when a priceless diamond disappears during a photoshoot. Stylish and brisk, Blood Orange blends postwar noir intrigue with Fisher’s early flair for suspense — long before his Hammer Horror fame.

Hollywood favorite Tom Conway – famed for playing Sherlock Holmes, The Falcon, Bulldog Drummond and Simon Templar – stars in this sharp-edged crime thriller from director Terence Fisher. Co-starring Naomi Chance as a model hiding dangerous secrets and Richard Wattis as a grumbling police inspector, Blood Orange has been painstakingly restored by Hammer in 4K from the original film negatives.

Ex-FBI agent turned private eye Conway is called in to investigate a jewel robbery at an exclusive London fashion house. But when murder enters the frame, the catwalk becomes a crime scene – and the killer is still at large.
