Cold rain poured endlessly over the dark, sprawling Blackwood estate. Detective James Thorne stepped through the heavy, grand oak doors. A bloody body lay motionless upon the expensive Persian rug. Lord Harrington had a silver dagger sticking from his chest. The grandfather clock chimed midnight as terror filled the room. Four nervous guests stood quietly near the crackling marble hearth. Everyone possessed a dark secret worth killing to protect tonight. Thorne noticed a torn silk glove resting beside the corpse. The murderer was undoubtedly still waiting inside this locked house.
