Detective Mara Quinn arrived at the gloomy mansion at midnight, her coat dripping, her flashlight cutting through the thick fog. Inside the library, Lord Edmund Blackwood lay motionless beside his overturned chair, a silver dagger protruding from his chest dramatically. Five nervous guests stood silently near the fireplace, exchanging guilty glances while avoiding the detective's sharp, questioning, and relentless stare. The grandfather clock struck one as Mara knelt carefully, noticing a torn photograph clutched tightly within the dead man's hand. She unfolded it slowly and gasped, recognizing her own younger face smiling beside Edmund, someone she had sworn to forget. Outside, thunder crashed violently as the lights flickered, died completely, and a woman's terrified scream echoed through the darkened hallways.
