The thunder roared fiercely as rain battered the old mansion’s windows. Detective Harris arrived silently, noting the eerie glow inside the study. A body sprawled across the carpet, a dagger wrapped in crimson silk. Stranger footsteps echoed outside, but no one claimed to hear anything. The clock struck midnight as secrets whispered silently through shadowed corners. Lamps flickered ominously, casting strange shadows on the antique walls. A single note lay beside the deceased, words smudged and unreadable. Everyone gathered quietly, tension thickening in the cold, damp air. Unseen eyes watched from darkness, waiting for the truth to reveal itself. The night’s darkness hid more than rain and secrets; it hid lives.
