Rain hammered the cobblestone streets as the town's clock struck midnight, casting shadows over the abandoned manor and whispered secrets. Detective Elise Marlowe arrived, her trench coat soaked, clutching a crumpled note that read, 'Meet me tonight' at the lighthouse. The lighthouse's lantern flickered, revealing a bloodstained dagger lying beside a shattered glass bottle and a torn photo of child. Footsteps echoed from the manor's attic, where a hidden door creaked open, exposing a spiral staircase descending into darkness below. A distant owl hooted, while the wind whispered the victim's name, sealing the night with ominous anticipation for the inevitable.
