Rain fell on Blackwood Manor. The clock struck eleven times. Nobody heard the butler scream. Blood stained the marble floor. A candle flickered then died. Lord Ashford lay perfectly still. His eyes stared at nothing. A dagger pierced his chest. The guests stood in silence. Nobody moved toward the body. Detective Cole entered the room. He surveyed each frozen face. Someone here knew the truth. Tonight nobody would escape questioning.
