Rain hammered the deserted platform. Eleanor Vale arrived after midnight. The midnight train stood silent. Its carriage doors gaped open. Inside, a gentleman sat motionless. Blood blackened his white waistcoat. A dagger pinned his ticket. Eleanor recognized the dead man. He had proposed yesterday morning. Behind her, leather soles scraped. Every carriage door slammed shut. The train began moving west. His ticket bore Eleanor’s name.
