Acknowledgments

In writing this book I have had some distinguished helpers, including Steve Band, who was the chief of the FBI Behavioral Science Unit from 1998 until 2005, and its newly appointed chief Harry Kern. This book also owes a major debt to Robert K. Ressler, and to FBI Agent Gregg McCrary.

I also wish to thank Sondra London for reading and making suggestions for the sections on Gerard Schaefer and Danny Rolling.

My friend Wilton Earle, the chronicler of the crimes of “Pee Wee” Gaskins, has also contributed his own invaluable insights into the case.

Finally, I also owe a debt of gratitude to Britain’s first and still its most distinguished criminal profiler, Professor David Canter.
