The autumn wind howled through the skeletal branches of the ancient oak tree as darkness descended upon the quiet village. Inside the grand manor house, Lady Blackwood adjusted her diamond necklace while staring at the portrait of her late husband. The grandfather clock in the hallway struck twelve precisely as a scream pierced the silence from the old east wing. Servants rushed through the marble corridors carrying candles that flickered wildly in the sudden draft from the dark open window. In the library, Detective Inspector Mills discovered Lord Ashford slumped over his desk with a smoking pistol lying right there.
