The manor stood in fog. Its iron gate hung ajar. A single light burned upstairs. Detective Mara pulled her coat. Her boots crunched wet gravel. The front door opened slowly. The grandfather clock ticked loudly. A candlestick lay near steps. Dark droplets marked the floor. She knelt beside the body. His silver watch was missing. No weapon rested in sight. The room smelled of cinnamon. A torn letter lay nearby. Someone left a red thumbprint. Mara heard a floorboard creak.
