Rain lashed violently against the stained glass of the parlor. Inside, Lord Blackwood lay entirely motionless upon the Persian rug. A silver letter opener jutted straight from his velvet chest. Crimson blood slowly soaked into the antique threads beneath him. The grandfather clock chimed midnight with twelve deep, heavy tolls. Detective Cross knelt quietly beside the body to inspect clues. The victim held a torn photograph within his stiff fingers. Somebody had fled through the open terrace doors into darkness. Footprints trailed across the wet mud toward the shadowed woods. The killer was definitely still roaming the vast estate grounds.
