Thunder shook the old manor while rain beat against the dusty glass of the grand library on the lonely hill. Lord Harrington slumped lifeless across his mahogany desk, a silver dagger protruding sharply from between his rigid cold shoulder blades. A grandfather clock struck midnight in the dark corner, its rhythmic chime masking the quiet footsteps fleeing down the corridor. Detective Vance stepped quietly into the shadow, examining the spilled red wine that mixed slowly with fresh, dark, pooling blood. The heavy oak door was locked from the inside, meaning the ruthless killer was definitely still trapped in this room.
