Model response

AI
At midnight, Detective Mara Vale arrived at Blackthorn Manor, where the front door stood open beneath a flickering porchlight. Inside, a grandfather clock struck thirteen, and someone upstairs whispered her name before the final chime faded into silence. She found Lord Blackthorn in the library, slumped over his desk, his fingers curled around a small brass key. Beside him lay a fresh newspaper, dated tomorrow, with its headline announcing the detective's own murder before dawn arrived.
