Rain polished the empty platform. Inspector Vale arrived before sunrise. A suitcase waited near benches. Blood darkened its brass latches. No body occupied the station. Yet someone whispered her name. Vale turned toward the clock. Its hands pointed straight downward. Beneath it, shadows shifted softly. A porter emerged, trembling badly. “She missed the midnight train.” “Who?” Vale asked, approaching him. The porter swallowed, then collapsed. Inside his pocket, bells chimed.
