The detective stood quietly beside the body that lay still upon the cold marble floor inside the dim library room. Rain tapped steadily against the tall windows while thunder rumbled through the heavy clouds above the sleeping village last night. A single candle flickered near the broken vase that held wilted roses next to the opened ledger books yesterday evening. The blood stains spread across the Persian rug while servants whispered hushed secrets inside the shadowy hallway outside the door. Every guest wore masks of sorrow while detectives searched for clues hidden beneath the dusty old portraits hanging high there.
