Detective Vance stared coldly at the bloody corpse on the floor. Rain hammered heavily against the locked study window outside tonight. Expensive art pieces hung crookedly across the dimly lit walls. No signs of forced entry disturbed the pristine antique rug. The victim clutched a gold pocket watch in his hand. Time had stopped permanently at midnight for the wealthy lord. Vance knelt closer to examine the fatal wound very carefully. Someone in this grand mansion desperately wanted the old man dead.
