The old manor house sat silent and still on the hill as the autumn wind began to blow very strongly. Detective Inspector Marlowe stood at the tall iron gates and stared up at the dark windows of the old mansion. A single yellow light burned in the attic window, flickering like a dying candle in the very deep thick gloom. Three guests had arrived for dinner but now only two remained alive inside the drafty dining room this cold night. Blood had stained the Persian carpet crimson, pooling beneath the antique chandelier that hung like a spider way up overhead. The victim lay sprawled across the mahogany table, his eyes wide open and his throat cut from ear to ear. No one had heard the scream because the storm outside had swallowed every single sound with its angry howling gusts. Marlowe pushed open the heavy oak door and stepped into the room, his shoes crunching on the broken crystal glass.
