Rain hammered Blackthorn Manor while Inspector Vale examined muddy footprints ending beneath the library's locked and bloodstained oak door that night. Inside, Lord Ashcombe sat upright beside the fire, a silver letter opener buried precisely between his shoulder blades, gleaming coldly. Every window remained latched, every servant claimed innocence, and the grandfather clock had stopped thirteen minutes before midnight without explanation. Then Vale noticed six untouched glasses, seven damp coats, and one fresh rose petal resting upon the dead man's tongue.
