Heavy rain washed against the mansion windows while Detective Miller stared down at the cold, lifeless body on the rug. A shattered glass of expensive whiskey lay near the victim's hand, spilling amber liquid across the polished dark wood floor. No signs of a struggle existed anywhere in the room, suggesting Lord Blackwood knew his ruthless murderer quite well indeed. The antique silver pocket watch tucked neatly inside the dead man's velvet suit jacket had stopped abruptly at midnight sharp. Outside the locked study door, five terrified houseguests waited nervously for the detective to reveal who held the bloody key.
