Rain hammered the cobblestones outside the manor, while candles flickered nervously inside the dim drawing‑room as the wind whistled through. The butler, eyes haunted, entered quietly, clutching a trembling envelope stamped with crimson ink, whispering his name: Edward for danger. Lady Marlowe, draped in midnight silk, stared at the candlelit portrait, noticing a trembling shadow where her husband once smiled. A sudden scream shattered the silence, echoing through corridors, as the chandelier swayed, casting frantic silhouettes upon cracked walls alone. Detective Hawthorne arrived, notebook in hand, his mind already assembling fragments, suspecting the night itself might be the killer still.
