The rain stopped just as Inspector Vale reached Blackthorn House. One upstairs window glowed, though the family claimed nobody remained. Inside, a grandfather clock ticked beside the untouched dinner plates. Then Vale noticed wet footprints crossing the carpet toward nowhere. At the staircase, Mrs. Wren held a bloodstained silver key. She whispered, “You’re early,” then vanished before he could answer. Vale followed, finding one door locked securely from the inside. Behind it, someone laughed once, then begged for silence again. Vale raised his old revolver; the downstairs clock suddenly stopped.
