The detective arrived at the old manor just before midnight. Rain hammered the windows while thunder rolled across the valley. A maid screamed when she found the cold body upstairs. Blood stained the carpet beside the open wooden library door. The victim lay still with one letter clutched tightly nearby. Every guest claimed innocence before the detective asked any questions. Someone inside that quiet house knew exactly what happened tonight. The clock struck twelve and the investigation truly began then.
