The storm howled around the ancient mansion, windows rattling in their frames, as Detective Miller pulled up the gravel drive. Inside, the grand hallway was silent except for the ticking clock, its echoes bouncing off paintings and dark wood paneling. The detective's eyes were drawn to the library door, slightly ajar, where a shaft of light sliced through the darkness. Pushing it open, he froze; on the Persian rug, a body lay prone, a silver letter opener protruding from its back. The victim's face was frozen in a final, silent scream, eyes wide, staring up at the ceiling's swirling plaster cherubs.
