The rain stopped at midnight. Blackthorn Manor held its breath. Detective Mara Venn arrived alone. The front door stood open. Inside, every clock had stopped. A single candle burned upstairs. Mara followed its trembling light. Lord Blackthorn lay very still. His lips were stained blue. A note covered his heart. A silver knife pinned it. Fresh ink spelled Mara Venn. Behind her, darkness softly breathed.
