Rain mercilessly polished the windows of Blackthorn Manor before midnight. Inside, twelve guests waited beneath the chandelier's trembling amber light. Colonel Vale announced dinner, smiling despite thunder raging wildly outside. Nobody noticed the butler locking every door with deliberate care. At midnight, the lights vanished, swallowing laughter, music, and certainty. A scream rose upstairs, sharp enough to silence even thunder. When lamps returned, Lady Harrow lay dead beside spilled roses. Her pearl necklace glimmered, though blood darkened the ivory carpet. Detective Morrow arrived smiling, carrying no umbrella, only questions tonight. He studied the body, then glanced toward the silent guests. Each face reflected grief, but one concealed a private triumph. Outside, rain erased footprints leading from the garden entrance completely.
