The room in Hatton Manor is sealed for a reason. It’s where Harvey Thorne went mad and placed a curse on the family. Now his great-nephew Harris wants to open it up, but his brother Brian, a clairvoyant, warns him against the idea. Harris is the first to perish, but there will be others. Each time, the victim has seen something unimaginable from the doorway and each time there has been a wet patch on the carpet in front of the fireplace. And yet it seems such an ordinary room… In this, the thirteenth of Paul Halter’s books to be published by Locked Room International, Inspector Archibald Hurst and Dr. Alan Twist are on the trail of one of the most diabolically cunning murderers ever.
