Rain hammered the old manor roof all through the night. Inspector Cole arrived at dawn to examine the dead corpse. Victor Shaw lay motionless down beside the cold fireplace hearth. No one heard the struggle during that long terrible storm. But his secretary discovered the body before that breakfast arrived. She found a bloodstained letter clutched tightly in his hand. The letter mentioned debts, betrayal, and one hidden dangerous secret. Cole pocketed it carefully while studying the locked bedroom door.
