I loved this book. It was written for teen readers I think, and I read it after I had surgery. It was the perfect book for recovery–light, interesting, and engaging. The story is about an ex-con who rents a room in London and figures out that he can use the London sewer system to rob the houses of the rich. He does so and creates two distinct personalities for himself: one of the rich gentleman and socialite, and the other as a dirty servant. He has to juggle these two personalities and keep up the charade in-order to enjoy the high life.
