Rain polished the station windows. Inspector Vale arrived before dawn. Inside, every clock showed midnight. Someone lay beneath the timetable. Her throat wore crimson ribbons. Her luggage contained three keys. A porter watched without blinking. “She arrived yesterday,” he whispered. Vale examined her unused ticket. Its destination had been erased. Across the back: his signature. He had never seen her.
