A single white shoe lay abandoned beneath the gaslamp tonight. Detective Marlowe arrived with rain darkening his tweed shoulders again. She lay on cobbles, eyes open, mouth whispering unspoken secrets. A bloodstain mapped a slow and terrible cartography across pavement. Neighbors gathered like curious moths arranged around the lamplight quietly. Someone had scrawled a name on the doorstep, hurriedly tonight. Footprints led away, muddy prints vanishing toward the river bridge. The postman swore he heard shouting, then a stifled scream. Clocktower chimed three; witnesses glanced at wrists, unwillingly confessing time. In the alley, a crimson handprint outlined a final clue.
