Operation Greylord by Terry Hake, Logo

The True Story of an Untrained Undercover Agent and America's Biggest Corruption Bust

A Gripping True Story of Corruption & Betrayal

Operation Greylord was the largest undercover public corruption investigation in FBI history. For 3½ years, Terry Hake (Terrence Hake) worked undercover in Chicago's court system, posing first as a corrupt prosecutor, accepting bribes from attorneys, and later as a corrupt criminal defense attorney paying off judges for the dismissal of cases. During the investigation, a judge's chambers were bugged for the first time in the United States and Hake became an FBI agent while undercover, another first. The operation resulted in charges against 103 judges, lawyers, and court personnel. The story has never been told by an insider — until now.

Operation Greylord is a detailed account of Mr. Hake's experiences as an untrained undercover agent at the center of the biggest corruption bust in American history. The book is published by Ankerwycke, an imprint of The American Bar Association.
