The rain poured heavily as dusk cloaked the small, eerie town. A broken window revealed shadows dancing in the dim candlelight. Detective Harris arrived at the scene, eyes sharp and focused intently. The silent victim's hand clutched a crumpled, bloody note tightly. Footprints led away from the house toward the foggy, desolate street. Whispers of long-held secrets floated through the chilly, midnight air. Neighbors peeked nervously from curtains, wary of the dark night's danger. A single, broken pendant was found near the bloodstained wooden floor. The sound of distant thunder echoed ominously through the deserted alleyways. Harris deduced quickly — tonight’s crime was more than just murder.
