Henri Bencolin

In the smoke-wreathed gloom of a Parisian salon, Detective Bencolin has summoned his allies to discuss a peculiar case. A would-be murderer, imprisoned for his attempt to kill his wife, has escaped and is known to have visited a plastic surgeon. His whereabouts remain a mystery, though with his former wife poised to marry another, Bencolin predicts his return. Sure enough, the detective's worst suspicions are realised when the beheaded body of the new suitor is discovered in a locked room of the salon, with no apparent exit.

A dark shadow looms over the Rhineland, where Inspector Henri Bencolin and his accomplice Jeff Marle have arrived from Paris. Entreated by the Belgian financier D'Aunay to investigate the gruesome and grimly theatrical death of actor Myron Alison, the pair find themselves at the imposing hilltop fortress Schloss Schädel, in which a small group of suspects are still assembled. As thunder rolls in the distance, Bencolin and Marle enter a world steeped in macabre legends of murder and magic to catch the killer still walking the maze-like passages and towers of the keep.

As the thick, autumnal fog chokes the capital, within the fire-lit lounge of London's notorious Brimstone Club a bizarre tale is being spun for Inspector Bencolin and his friend Jeff Marle. A member of the club has been sent a model of a tiny gallows, and the word is that the folkloric hangman Jack Ketch has been stalking the streets for victims by night. The threat of this supposed bogeyman becomes thrillingly real when that same night Bencolin and Marle are almost run down by a limousine with a corpse behind the wheel.

Last night, Mademoiselle Duchêne was seen heading into the Gallery of Horrors at the Musée Augustin waxworks, alive. Today she was found in the Seine, murdered. The museum's proprietor, long perturbed by the unnatural vitality of his figures, claims that he saw one of them following the victim into the dark; a lead that Henri Bencolin, head of the Paris police and expert of impossible crimes, cannot resist.
