ACKNOWLEDGMENTS

Grateful thanks to Stephen Morrow at Dutton for his astute and careful work on the manuscript, which turned this labor into a pleasure. And to my agent, Patrick Walsh, whose enthusiasm and energy got the project off the ground. Rohin Francis, Andrea Sella, Hugh Devlin, and Stéphane Burtey offered obscure diagnoses and other specialist expertise, which was much appreciated—as did my wife, Jenny, who endures my queries with heroic forbearance. Thanks to all of you.
