Rain lashed against the tall, dark windows of the manor. Lord Blackwood sat silently in his heavy leather wingback armchair. A single crimson stain slowly spread across his white shirt. The grandfather clock struck midnight with twelve loud, booming chimes. Detective Miller stepped carefully into the dimly lit study room. He adjusted his damp coat and inspected the bloody corpse. An expensive glass of scotch lay shattered on the floor. No weapon was left anywhere near the dead old man. The heavy wooden door was locked securely from the inside. Somebody in this isolated house was a very clever killer.
