'Satan's Bedchamber' is a horror novel by Arthur Leo Zagat. It was set in an ominous, shadow-infested old castle that Elise's Russian husband had brought her to. But she never guessed the grisly, mind-shattering secret it harbored—until the gates of hell yawned wide, and the maimed and ravished form of her dearest friend became the mute, terrible omen of what was in store for her own horror-shaken body.
