The rain hammered against the windows of Blackwood Manor as the guests arrived for the weekend. Their laughter echoed through the grand hallway, masking the tension beneath polite smiles. A sharp gust rattled the antique chandelier, casting eerie shadows on the aged wallpaper. Each guest carried secrets—some heavy, some deadly—though none would admit it aloud. The butler’s gloved hands trembled slightly as he took their coats with exaggerated precision. A clock struck midnight, its chime lost beneath the storm’s relentless howling outside. The host, absent from the foyer, had left strict instructions for their arrival. Shadows stretched unnaturally long in the candlelit confines of the drawing room. Whispers slithered between the guests like serpents through dry grass. No one noticed the absence of one guest until the body was found.
