Rain hammered relentlessly against the stained glass of the manor. Lord Harrington lay stone cold upon the expensive Persian rug. A silver letter opener protruded sharply from his frail chest. Blood pooled slowly around an overturned glass of dark wine. Detective Miller adjusted his wet coat and scanned the room. The grandfather clock chimed midnight with a slow hollow tone. Nobody had entered this locked study since the evening meal. Yet a fresh muddy footprint ruined the clean hardwood floor.
