The rain fell hard against the pavement, washing away the sins of the city but not the blood spilled tonight. Detective Miller looked down at the body lying cold in the alleyway, casting a silhouette of tragedy and dark despair. A silver knife protruded from the victim's chest, glistening under the flickering streetlamp that buzzed with a dying electric hum. He crouched low to inspect the strange symbol carved into the handle, knowing this case would haunt his weary soul. Shadows danced along the brick walls as a sudden clap of thunder announced the arrival of his young rookie partner. Miller sighed deeply, pulling his coat tighter, because murder was the only constant thing in this godforsaken, lonely, dark town.
