Cold rain battered against the dark glass of Blackwood Manor. Inside the library, a golden grandfather clock struck midnight slowly. Lord Harrington sat motionless behind his heavy mahogany reading desk. A crystal glass of fine vintage wine lay shattered nearby. Dark crimson blood dripped steadily from his pale velvet collar. An ornate silver dagger remained lodged deeply within his chest. The butler screamed aloud when he opened the heavy doors. Footsteps echoed faintly down the distant, cold, shadowy back corridor. Someone had locked every exit before the silent killer fled.
