London 1870. A terrifying place for a young, beautiful woman of limited means. But Eliza is modern before her time. Not for her the stifling if respectable conventionality of marriage, children, domestic drudgery. She longs for more. Through her work as an artist's model, she meets the magnetic and irascible Devil - a born showman whose dream is to run his own theatre company. Devil's right-hand man is the improbably-named Carlo Bonomi, an ill-tempered dwarf with an enormous talent for all things magic and illusion.
