Mist fell upon the manor. The old house was silent. A maid unlocked the library. She smelled copper and dust. Sunlight cut through the gloom. It illuminated the sprawled body. His eyes were open wide. A letter opener jutted out. Dark blood stained the carpet. Her breath caught in her throat. She finally broke the silence.
