Rain poured down on street. Shadows moved beneath dim lights. A scream pierced the silent night. Detective Blake arrived, coat damp. Footsteps echoed near dark alley. A body lay cold, still. Blood pooled beneath pale face. No witnesses dared to linger. Blake knelt, eyes scanning clues. Someone had planned this carefully. A single shoe lay nearby. Something shiny caught Blake’s attention. He pocketed it, mind racing. Who wanted this victim dead? Answers hid within city’s secrets.
