Rain hammered Blackthorn Manor as Detective Mara Voss climbed the marble steps and found the great doors standing wide open. Inside, candles guttered along the empty hall, and a silver clock above the staircase struck thirteen without making any sound. At the far end, beside a toppled chair, Lord Ashcombe lay beneath his portrait with one hand pointing stiffly upward. A crimson thread crossed his lips, vanished beneath his collar, and reappeared around the key clenched inside his cold fist. Mara knelt, touched his cheek, then noticed the portrait showed the same room, except its painted doors were firmly shut. Behind her, the open doors slammed together, though no wind stirred the candles and no footsteps crossed the empty hall. Then the clock began again, and every candle died, leaving Mara alone with the corpse and footsteps beneath the floor.
