Special thanks to Bob Berkel, Jan Buchholz of the Minnesota Department of Corrections, Special Agent Michael G. Goergen of the Federal Bureau of Investigation (Ret.), Mark Hausauer, Keith Kahla, Douglas M. Mock, CFP, Alison J.

I also would like to express my debt to the crime writers who came before me, specifically Carroll John Daly, Dennis Lehane, and the late, great Mickey Spillane, to whom I pay homage in these pages (you’ll know where).
