Rain lashed against the tall stained glass windows of the ancient manor house, drowning out the grandfather clock's rhythmic ticking. Inspector James stood silently over Lord Blackwood’s lifeless body, noting the strange crimson stain blooming across his pristine silk waistcoat. A shattered porcelain teacup lay near the victim's frozen hand, its dark contents slowly seeping into the expensive Persian rug. Every heavy door to the library remained securely locked from the inside, ruling out any simple entry or quick escape. The clever killer was undoubtedly still hiding somewhere inside this grand house, waiting quietly among the frightened, unsuspecting evening guests.
