Synopsis by Hal Erickson
Blood Orange is an early effort from the British "shock shop" of Hammer Films. Hollywood's Tom Conway stars as a former FBI agent, living in contented retirement in London. Conway's quietude is interrupted when gorgeous model Delphi Lawrence is murdered. Ere the "The End" sign looms into view, Conway learns that the girl's death was tied in with a jewel theft. The film's title refers to the most valuable of the stolen gems.
