We are thrilled to welcome John Dickson Carr into the Crime Classics series with his first novel, a brooding locked room mystery in the gathering dusk of the French capital. In the smoke-wreathed gloom of a Parisian salon, Inspector 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 Inspector`s worst suspicions are realized when the beheaded body of the new suitor is discovered in a locked room of the salon, with no apparent exit. Bencolin sets off into the Parisian night to unravel the dumbfounding mystery and track down the sadistic killer.
