At midnight, thunder rattled windows throughout the silent Briarwood manor. Detective Mara Voss arrived before servants discovered Lord Ashcombe’s body. He lay beneath his portrait, smiling with unfamiliar crimson lips. A silver key protruded neatly from his clenched right fist. Beside him, twelve wet footprints ended abruptly on polished marble. Yet every door remained bolted, and every fireplace burned brightly. Mara knelt, noticing black candlewax beneath the dead man’s fingernails. Then the grandfather clock struck thirteen, startling everyone but Mara. She turned toward the portrait as its painted eyes closed.
