The Red Circle (1960)

Description

Fear and terror grip London. Anyone who refuses to submit to the extortionate demands of the "Red Circle" is punished with death. A note with a red circle is always found on the bodies. Inspector Parr of Scotland Yard is baffled. To calm the outraged public, London's best private detective, Derrick Yale, is assigned to assist him. Only after another murder do the two find a clue that leads them to an escaped death row inmate whose guillotine malfunctioned at the crucial moment. But who is this unknown man, marked with a red birthmark around his neck?
