At midnight, the manor clock struck thirteen above the harbor. Inspector Vale found the library door standing strangely wide open. Inside, Lord Ashcombe lay face-down beneath his shattered grandfather clock. A silver knife rested beside his still, outstretched right hand. No blood marked the carpet, though his shirt was crimson. Vale noticed wet footprints ending abruptly before the locked window. Behind him, someone whispered, “The murderer is still here now.”
