Heavy rain battered the tall gothic windows of Blackwood Manor while Detective Miller knelt beside the cold and lifeless corpse. A single silver dagger protruded from the chest of Lord Harrington, staining his expensive silk shirt with dark crimson blood. Every heavy oak door had been bolted securely from the inside, leaving absolutely no obvious escape route for the killer. Miller carefully examined the shattered grandfather clock nearby, which had stopped ticking at precisely midnight during the violent, fatal struggle. Five nervous guests waited downstairs in the parlor, and Miller knew one of them was hiding a very deadly secret.
