The body lay face down in the cold dark library. Detective Morris arrived at the scene just after midnight fell. Rain hammered the windows like a thousand tiny desperate fists. No one had heard the gunshot that ended his life. A glass of whiskey sat untouched beside his left hand. The victim was Harold Price, owner of the entire estate. His wife stood in the hallway, trembling but completely silent. She claimed she had been asleep when the murder happened. Morris knelt beside the body and studied the single wound. The bullet had entered cleanly, leaving almost no trace behind. Someone in this house knew exactly what they were doing. Three guests had stayed the night in the east wing. Each one had a reason to want Harold Price dead. Morris pulled out his notebook and began writing careful notes. Tonight would be long, but the truth always surfaces eventually.
