Lightning flashed across the empty street as midnight secrets lurked. Detective Ward stepped cautiously through the shadowed foyer toward darkness. A crimson pool spread beneath an overturned antique oak table. Silence weighed heavily until haunting moans echoed within lonely walls. The victim’s lifeless eyes stared blankly at peeling wallpaper patterns. Rain whispered secrets against broken windows, masking sinister footsteps approaching. Detective Ward inhaled sharply, preparing to confront shadows and danger. He clenched notebook, determined to unravel truth behind gruesome murder.
