The cold rain hammered against the broken window pane while shadows danced across the bloody floorboards of the old manor. Detective Miller stepped carefully over the shattered glass, his gloved fingers trembling as he reached for the cold silver pistol. Blackwood lay in his leather chair, a cruel smile frozen upon his face, a playing card tucked in his pocket. Somewhere deep in the dark corridor, a grandfather clock struck midnight, echoing through the silent halls like a funeral toll. Miller pulled a magnifying glass, eyes narrowing as he noticed the faint smell of bitter almonds lingering in the air.
