You'd have to be mad to steal from the feared International Patent Office. But that's what Elizabeth Barnabus is about to try. A one-time enemy from the circus has persuaded her to attempt a heist that will be the ultimate conjuring trick.
Hidden in the vaults of the Patent Court in London lie secrets that could shake the very pillars of the Gas-Lit Empire. All that stands in Elizabeth's way are the agents of the Patent Office, a Duke's private army and the mysterious Custodian of Marvels.
Rod Duncan returns with the climactic volume of the Fall of the Gas-Lit Empire, the breathtaking alternate history series that began with the Philip K. Dick Award-nominated The Bullet-Catcher's Daughter.
