I owe many debts in the creation of this work, some more obvious than others.
My wife, Kristine, as always was my reader of first resort; with this book, however, she was joined in this labor by our oldest son, Geoffrey, who proved himself to be a reader of great insight and an editor with a good eye for detail. The world has too few good editors. I'm proud to have found another one.
I must also thank the many friends working with me on other projects, who waited patiently until this book was finished, so that I could return to other labors too long delayed. And thanks, again and always, to my agent, Barbara Bova, who proves that it is possible to do good business with a good friend
