Heavy rain battered the tall windows of the gothic mansion. Detective Vance stood silently over the cold, lifeless millionaire’s body. Crimson blood stained the expensive Persian rug beneath his feet. A shattered teacup lay discarded near the heavy velvet curtains. Someone had poisoned the bitter tea just before midnight struck. Three nervous suspects waited quietly inside the dimly lit hallway. Every single person in this house held a dark secret. Vance adjusted his wet trench coat and grabbed his notebook. Nobody would leave the locked estate until the killer confessed. Outside, a sudden flash of lightning illuminated the dark grounds.
