Cold rain needled Blackthorn Manor while the midnight bells sounded. Inside, twelve silent dinner guests watched the library doors open. Lord Vale entered smiling, then collapsed beside the roaring fire. A slim silver letter opener protruded between his shoulder blades. Detective Mara Venn arrived before any guest thought to scream. “No one leaves,” she said, turning the old brass key. The library lock clicked, sealing every guest inside with death. On the mantel, a fourteenth place card bore her name.
