The rain fell hard against the old mansion's dark windows. Detective Mara Quinn arrived precisely at midnight, soaked and silent. Inside, a body lay sprawled beside the overturned mahogany desk. Blood pooled slowly across the marble floor toward her boots. No weapon gleamed anywhere within the locked, silent study room. Seven guests waited upstairs, each hiding secrets behind pale faces. Someone among them had killed Lord Ashworth before dinner ended. Mara knelt carefully, noticing ash scattered near his right hand. A single match rested there, still warm, smelling faintly sweet. Outside, thunder cracked, and somewhere upstairs, a woman began screaming.
