The cold rain lashed against the heavy oak library doors. Lord Blackwood lay silent upon the crimson patterned Persian rug. A silver letter opener protruded from his stiff velvet waistcoat. The clock on the mantle ticked toward a lonely midnight. Inspector Miller removed his wet hat and sighed very deeply. No one heard the scream over the crashing summer thunder. Only the ginger cat witnessed the shadow leave the room. Broken glass glittered like diamonds scattered across the wooden floor. The scent of expensive brandy lingered in the stagnant air. Someone in this manor house was definitely a cold killer.
