RADIX: A CJ Hawk - FBI Origin Story

by F.X. Regan

According to Merriam Webster, the Latin word for root is RADIX. It’s often used to describe origin, or beginning, usually in mathematics, which makes it the perfect title for this book - CJ Hawk’s origin story. The book is for everybody, those who have read one or all the CJ HAWK – FBI Thrillers; DEPARTMENT ECHO, ZULU CENTER, and WASHINGTON FIELD. Or if you haven’t read any of these thrillers, it is an introduction that maybe brings you to these stories.

CJ Hawk was an Alexandria, Virginia police sergeant who became an FBI agent. Five years into his FBI career he was “Removed from the Rolls” for his part in a bank robbery takedown that resulted in the death of a fellow agent. Despite inheriting a hundred million dollars from his father, he quickly became bored and started a high end private investigations firm. As a PI, Hawk would go on to solve several complex investigations in DEPARTMENT ECHO, ZULU CENTER, and WASHINGTON FIELD.

But there is more to the CJ Hawk story. How an upper middle-class kid abandoned his father’s plans for him to take over the family business and go into law enforcement instead. And how he worked to keep himself grounded with his fellow officers and agents when in many ways they had nothing in common.

Ryan Steck, best selling author and "The Real Book Spy," said of F.X. Regan’s writing, "Written by a former FBI Agent who knows this world inside and out, his thrillers are the FBI books you don't want to miss."
