I have read all of Silva's books, most of them more than once. I am not sure what to make of this one. In his notes at the back , Silva claims that this is all a work of fiction, and maybe so. But Silva has also used it a a platform on which to editorialize on the historical failings of the Roman Catholic Church, a faith which he himself was born into. He also makes some not-so subtle criticisms of the current US administration. If he was so intent on writing a book like this, he should have considered writing it as a separate work of non-fiction, and not rolled it under the banner of a Gabriel Allon novel. He is a character than I and many, many readers enjoy very much. Let's hope that this is not a new trend by Silva, and simply a one-off. The Prince of Fire deserves no less.
Lets hope his next one brings back some of his great characters like Christopher Keller, Sarah Bancroft, Julian Isherwood, Graham Seymour , Adrian Carter and others.
