Night descended on Marrow Lane. Rain drummed softly on rooftops. Streetlights flickered in eerie sequence. A scream shattered the cold silence. Blood pooled near the garden gate. Footsteps echoed, hurried and uneven. A figure crouched beside shadows. Gloved hands searched for hidden evidence. Sirens wailed in the distant background. Detective Maren arrived, trench coat fluttering. She surveyed the chilling crime scene. Neighbors gathered, whispering in anxious clusters. No one saw the murder. But everyone felt its sharp presence. Maren knelt, studying faint footprints. Some secrets waited in the darkness.
