Rain stitched the midnight streets. A bell tolled inside Blackthorn. Inspector Vale found the door. It stood open without sound. Candles burned beside cold porcelain. Lord Ashcombe lay beyond them. His signet ring was missing. No footprints crossed the marble. Yet roses scented the study. Someone had wiped the glass. Vale pocketed one black feather. Outside thunder named the hour.
