Heavy rain battered the tall gothic windows of Blackwood Manor while thunder rattled the antique porcelain teacups on the table. Lord Harrington lay motionless beside the cold fireplace, a crimson stain slowly spreading across the front of his silk shirt. Detective Miller knelt carefully near the corpse, shining his bright silver flashlight over the shattered glass scattered across the rug. A golden pocket watch lay smashed beneath his pale lifeless hand, its delicate pointers frozen forever at precisely eleven fifteen. Five nervous guests stood huddled together near the heavy oak doors, watching the silent investigator with wide and terrified eyes. Miller knew without any doubt that the ruthless killer was still hiding somewhere inside this locked and shadowy country estate.
