I want to thank Shane Salerno for believing in me and for doing more than any one person could ever be asked to do to make this new series a reality. Thanks, also, to Edward Tsai, Don Winslow, and everyone associated with The Story Factory.
I’m grateful to Ivan Held, Sara Minnich, and everyone else at G. P. Putnam’s Sons.
Thanks to Chicago police detective John Campbell for all of the technical assistance. And continuing thanks to Bill Keller and Frank Hayes.
And, as always, I couldn’t do anything at all without Julia, my wife and best friend, and Nicholas and Antonia, who both amaze me more and more with each passing day.
