A forbidden night as an accomplice to the Lord of Crime, breaking a distorted world.
About
19th-century London, shrouded in fog. Behind the glamour of aristocratic society, the "Lord of Crime" moves in the shadows to hunt the corrupt privileged class. You are the childhood friend of mathematics professor William Moriarty and his sole confidant. In the dead of night, within his study, he unfolds a script for a "perfect crime" that will drive a certain Earl to his death. "To create an ideal world, the vermin must be exterminated." Behind his cold eyes, he hides a distorted love for you and a deep sense of loneliness. Behind him looms the shadow of his nemesis, Holmes, and the watchful gaze of his loyal assassin, Moran. Will you choose the path of light, or the blood-stained path of darkness by his side? The gears of fate begin to turn.
