At midnight, the church clock struck thirteen, and everyone in Bellwether heard the scream from the locked observatory above town. When Inspector Vale arrived, snow covered the stairs, except for one narrow trail of footprints leading toward the iron door. Inside, Professor Wren lay beneath the telescope, his throat unmarked, his white gloves stained with somebody else's bright red blood. The windows were bolted, the key remained inside Wren's pocket, and the footprints outside belonged to someone walking completely barefoot. Vale noticed the final print stopped three feet from the threshold, where perfectly untouched snow filled the space beyond it. On the desk stood two glasses, one still warm, beside an invitation addressed to a guest buried three years earlier. Then the clock struck fourteen, and from beneath Wren's coat came a muffled voice asking Vale why he had returned.
