Rain polished the empty platform. Inspector Vale arrived before dawn. A porter guarded something pale. Beneath newspapers, Lady Winter waited. Her jeweled throat showed bruising. Nearby, the station clock trembled. Its hands pointed toward midnight. Yet midnight had never passed. Vale counted footprints beside hers. Five approached; only four departed. Then somebody whispered his name.
