The rain pounded the glass. Detective Vance entered the room. Shadows danced on the walls. A cold wind chilled him. Blood stained the Persian rug. Lord Blackwood lay perfectly still. A silver dagger pierced deep. His lifeless eyes stared upward. No breath escaped his lips. The killer left no trace. Vance knelt near the corpse. He inspected the brutal wound. This was no random attack. Someone wanted the lord dead. Thunder echoed through the mansion. The long night just began. Every suspect slept right upstairs. Lies would surface very soon. Vance pulled out his notebook. He wrote the first clue. The tall clock struck midnight. Time to find a murderer. A floorboard creaked behind him. Someone else was awake now. Vance slowly drew his gun. The deadly game started tonight.
