The mist clung to the cobblestones like a shroud. A single streetlamp flickered, casting long shadows. The victim’s body lay twisted beneath the dim glow. Raindrops tapped urgently against the cobblestones, echoing sharply. Detective Harlan adjusted his coat, eyes scanning the scene grimly. Blood pooled dark and glistening on the wet pavement. A torn glove lay abandoned near the outstretched hand. The victim’s scarf fluttered weakly in the chilling breeze. Neighbors’ whispers echoed from shuttered windows, muffled and afraid. Harlan knelt, examining tire tracks leading away silently.
