I liked the book and I think all fans of Jeffery Archer would enjoy it.

The mathematician in the book is portrayed positively, as the smart and resourceful leader of the gang who wants to steal back their money. After the beginning of the book I thought it would portray him according to the stereotype of being unfit to deal with the real world but in fact the book shows him as very clever in that he succeeds in repeatedly con a conster, as well as moral in that he doesn't steal back more than what he lost in the first place.

At one point the image that mathematicians are human calucators is mentioned and it is made clear that the mathematician in fact finds arithmetical calculations boring.
