(Dutton via AP) Riley Wolfe has surely met his match in “Fool Me Twice,” the second novel in Jeff Lindsay’s series about the self-proclaimed world’s greatest thief. This time, his target is Raphael’s “The Liberation of St. Peter.” The priceless work of art is a fresco. A fresco doesn’t hang on a wall. It is part of a wall, the paint embedded in the plaster. The wall in question, part of the Apostolic Palace, is more than 18 feet long. And the palace is located in one of the most heavily guarded places in the world – the Vatican.
