Fog clung to Alderwick Pier. The lighthouse blinked, slow, indifferent. Marian Vale arrived before dawn. Her boots whispered on planks. A gull screamed, then vanished. She found a lantern burning. Beside it lay Colonel Strath. His throat wore a ribbon. The ribbon was navy silk. Marian pocketed it, trembling slightly. Footprints circled, then stopped abruptly. Someone watched from misty shadows. A clockwork locket ticked nearby. It carried her name inside. Marian exhaled, counting suspects silently.
