In the thriller, Deadly Codes, Daniel Cormac Gallagher, Jr., a Boston private eye, is hired to investigate the death of Jennifer Clark, tragically killed in a car bombing in her own driveway.

Gallagher has been commissioned by Jeanne Campbell, Jennifer’s twin sister, to find a mysterious woman-Jennifer’s secret lesbian lover who vanished immediately after the bombing. While the authorities continue to pursue their suspicions that the terrorist act may have been intended for Jennifer’s husband, Bill, who holds a top-secret position in the counter-intelligence division of the National Security Agency, Jeanne reveals intricate details to Gallagher that intrigue him enough to take on the case. While Gallagher begins searching for the missing woman, he has no idea that a bounty has been placed on his own head-two hired gunmen are plotting to kill him. Gallagher’s search takes him to Washington DC, where he discovers that the car bombing is only a backdrop to a complex, treasonous scheme to sell code-breaking formulas to a hostile enemy nation.

As the violent mystery unravels, Gallagher finds himself under deadly attack from two shocking but powerful forces-one he knows and another he never expects.


This book is a great mystery with lots of twists and turns . Right from the beginning the author grabs you with his suspenseful story telling , and till the end will keep you guessing. Deadly Codes is fast moving and fun with a good cast of characters to keep you interested and entertained.

This  book is the second in the Gallagher novel series, the first one is “Fatal Gamble”, though I never read the first one (I want to , after reading this one), “Deadly Codes” can be read as a stand  alone too. The author has done a fantastic job of keeping the reader intrigued throughout while taking  us , readers, on a  thrill ride with our favorite detective Gallagher. O’Donnell has a gift for well-paced story-telling and a perfect sense of timing that effectively delivers all the hair pin twists and turns that you would expect from a suspense thriller.

I highly recommend this book as a must read and even worth buying!!! Can’t wait to read the first one and the third to come out……

Thanks Paula from Author Marketing Experts Inc. for this wonderful book.
