Cold rain battered the tall gothic windows while Detective Arthur Pendelton stared silently at the lifeless body on the rug. Lord Blackwood lay face down in a dark pool of crimson blood with a silver dagger protruding from his back. The heavy oak study doors had been bolted securely from the inside before the fatal strike ended his miserable life. A shattered gold pocket watch resting near his pale left hand proved the brutal attack happened right at twelve sharp. Downstairs in the grand parlor, six terrified dinner guests waited anxiously to hear what the famous investigator would say next. Every single person trapped inside this isolated mountain manor possessed a remarkably strong motive to want the wealthy aristocrat dead. Arthur knelt beside the cooling corpse and noticed a tiny torn piece of green velvet clutched within those stiffened fingers. Smiling grimly to himself, the veteran sleuth realized that the clever killer had just made their very first fatal mistake.
