Midnight fog clung to the desolate manor grounds in silence. Lord Blackwood was found lifeless in his study, murdered mysteriously. Detective Morgan entered, rain dripping from his dark trench coat. A single bloodstained letter lay on the mahogany desk alone. The butler claimed innocence, yet his trembling hands betrayed guilt. Outside, thunder roared, echoing the mansion's dread and hidden secrets.
