The good news is he knows who did it. But in order to exonerate himself, Harry must first make his escape--and figure out his own identity.

With the authorities hot on his heels, Harry travels from New York and Boston to Paris and the Vatican in search of an elusive stage magician. Eventually piecing together his mysterious past, he descends into the dark world of the occult. And very soon he will have vengeance upon the devil himself . . .
