Heavy rain battered the frosted windowpanes of Blackwood Manor while the grandfather clock in the dim hallway struck midnight loudly. Lord Harrington lay slumped motionless across his mahogany desk, a silver dagger protruding neatly from between his rigid shoulder blades. Dark crimson blood soaked through his expensive silk waistcoat, dripping slowly onto the antique Persian rug below his leather chair. The heavy oak door remained securely locked from the inside, and the only brass key rested beside his untouched drink. Detective Vance extinguished his damp cigarette, stepped over the shattered glass, and quietly whispered that the killer was still inside.
