London, 1888. The nightmares arrive before the murders—visions of lightning, ink, the mark VI, and laughter in the dark. After tragedy, John Pepo is drawn to Whitechapel’s fog-choked streets, where a man calling himself Jack the Ripper steps from the shadows with an impossible proposal. Bound to a killer and hunted by unseen hands, John is pulled into a gaslamp dark fantasy horror of demons, witches, and whispered bargains—strings tightened by a puppeteer known as Old Nick.
