At midnight, Detective Mara Voss arrived at Blackthorn Manor, where every clock had stopped beside its murdered owner's body. The victim lay beneath a chandelier, clutching a white chess knight that had belonged to his missing youngest daughter. Outside, fresh snow covered the grounds, but one set of footprints began at the locked library door and ended nowhere. Mara noticed three wineglasses on the desk, though the butler insisted his master had spent the evening entirely alone. Then the grandfather clock struck thirteen, and someone behind the wall whispered that the wrong person had been killed.
