At midnight, Detective Mara Vale arrived at Blackthorn Manor, where the front door stood open beneath a flickering porch lamp. Inside, the grandfather clock had stopped at eleven, and muddy footprints crossed the carpet toward the locked study at dawn. When Mara forced the study door, she found Lord Blackthorn dead beside his desk, clutching a silver key in hand. His daughter claimed the key opened nothing, but Mara noticed fresh scratches around the locked cabinet beside the cold fireplace. From somewhere upstairs came three slow knocks, though every guest stood behind Mara, watching the cabinet swing open without warning.
