‘That Devil’s Trick makes a valuable contribution to the history of nineteenth-century mesmerism and medicine. In focussing on the non-medical press, Hughes has greatly expanded our appreciation of both the range and longevity of contemporary debates on mesmerism. In doing so, he presents us with a rich and nuanced history of a pseudoscience that, for all its fluidity, ultimately remained fixed at the fringes of medical respectability.’Karl Bell, University of Portsmouth‘I would thoroughly recommend the book to anyone working in this area since Hughes’s new research method has uncovered a host of original new materials and done a massive job of synthesis. He is to be commended for a serious and weighty volume of research that nuances our understanding of this aspect of nineteenth-century culture.’ Roger Luckhurst, Birkbeck, University of London, Victorian Studies (issue 60.1) Autumn 2017
