London,1837. Jack Maggs, raised and deported as a criminal, has returned from Australia, in secret and at great risk. What does he want after all these years, and why is he so interested in the comings and goings at a plush townhouse in Great Queen Street? And why is Jack himself an object of such interest to Tobias Oates, celebrated author, amateur hypnotist and fellow burglar - in this case of people’s minds, of their histories and inner phantoms? A thrilling story of mesmerism and possession, of dangerous bargains and illicit love against the backdrop of Victorian London.
