The rain fell hard on the cobblestone streets below. A single streetlamp flickered weakly in the cold night. Detective Clara Voss adjusted her damp overcoat carefully. Her breath formed small clouds as she exhaled slowly. The victim’s body lay sprawled near the alley’s edge. Blood pooled darkly beneath the pale moonlight’s glow. A crumpled note clutched tightly in the stiff fingers. Clara knelt down, her gloved hand trembling slightly. The words scrawled hastily read, *"You should have stayed away."* She stood abruptly, her instincts screaming danger was near.
