Detective Mara Quinn arrived at Blackwood Manor precisely as midnight rain hammered the crumbling gothic windows relentlessly tonight without mercy. The butler opened the massive oak door, his trembling hands betraying years of loyal, terrified silence within these cursed walls. Upstairs, Lord Ashford lay sprawled across his study, a silver letter opener embedded in his chest still warmly bleeding quietly. Mara knelt beside the body, noting the shattered brandy glass and muddy footprints leading toward the balcony outside despite storm. Someone in this house murdered him, she whispered, and that someone still listens from the shadows just beyond our hearing.
