Rain battered the shuttered windows. Inside, thirteen guests awaited dinner. The fourteenth lay upstairs, dead. Detective Mara Vale arrived uninvited. Her coat smelled of seawater. Nobody asked about the blood. Lord Ashcombe had summoned everyone. His letter promised an inheritance. Now his solicitor was missing. The butler refused her handshake. Instead, he offered a key. “This was beneath his tongue.” Mara climbed without another question. Behind her, someone started laughing. The laughter stopped too quickly. Ashcombe’s bedroom smelled of oranges. His throat bore purple fingerprints. Every mirror faced the wall. A letter rested beside him. Mara recognized her own handwriting. She unfolded the brittle paper. Only five words appeared inside. “You should have stayed buried.”
