of the eponymous Italian ambassador to the Holy See of the late 1930s, for allowing me to use a photograph of the ambassador from the family archives.
Wendy Strothman, my friend and literary agent, deserves special credit. Her deep knowledge of books and publishing, her literary judgment, and her strong support have meant much to me. I am also fortunate to have had David Ebershoff, of Random House, as my editor. It is rare to have an editor who is also such a talented and accomplished writer himself, and I feel deeply grateful to have had the benefit of David’s keen literary eye and his belief in the importance of this book. He has made this a much better book. Thanks as well to David’s talented assistant, Caitlin McKenna, for all her editorial efforts. I am grateful as well for all the other support I received at Random House and would like to thank especially Dennis Ambrose, Michelle Jasmine, Susan Kamil, Michael Gentile, and Lani Kaneta for all they have done.
Finally, to my wife, Susan Dana Kertzer, who has lived with this book for many years, sharing in the pleasures of life in Italy. She has never let me forget the goal of writing a book that not only the experts but people who know little of this history will want to read. If I am lucky, one of her book groups may even read it.
