Publisher's Summary

The highly anticipated 21st FBI thriller by New York Times number one best-selling author Catherine Coulter presents Agents Savich and Sherlock with two baffling mysteries. Working with Agent Cam Wittier (Insidious) and New York-based former Special Forces agent Jack Cabot, they must race against the clock to catch an international criminal and solve the enigma of the man called John Doe.

When Agent Dillon Savich saves Kara Moody from a seemingly crazy man, he doesn't realize he will soon be facing a scientist who wants to live forever and is using "John Doe" to help him. But when the scientist, Lister Maddox, loses him, he ups the stakes and targets another to take his experiments to the next level.

It's a race against time literally as Savich and Sherlock rush to stop him and save both present and future victims of his experiments. In the meantime, Cam Wittier and Jack Cabot must track a violent criminal through the Daniel Boone National Forest. When he escapes through a daring rescue, the agents have to find out who set his escape in motion and how it all ties into the murder of Mia Prevost, the girlfriend of the president's Chief of Staff's only son, Saxton Hainny. It's international intrigue at the highest levels and they know they have to succeed or national security is compromised.

Featuring Coulter's signature "breakneck plot and magnetic characters" (Huffington Post), Enigma is a shocking thrill ride.

[nothing nice]

Embarrassingly bad. Characters seem interesting if the story wasn't so cringe worthy. Dialogue I hope to forget.

Easily distracted

All voices fit the characters which makes or breaks an audible. Would read this author if I happened on a positive review but will not seek out. I did like the complexity of the story.

Enigma! A must read book!

I love Catherine Coulter's FBI Thriller books, as usual I have enjoyed this book as well as the all of the rest I have read. Once again Ms.Coulter you have written another great one ! this was the first audio book service I have ever used, and I must say I have enjoyed it. I listened to it while driving, while crocheting and even cooking diner.

Not my favorite of the FBI Thriller series.

The story did not seem to be as fast past as prior books in this series. I typically like Catherine Coulter but found this one difficult to get through. Hoping the next one will be better. The performance was fair.

Great addition to the FBI Thriller Series

Catherine Coulter has written another great addition to the FBI Thriller Series. As always, her storyline is original with heart-stopping action. I highly recommend this book.

Best in Series in A Long Time

I felt this was the best novel in the series in a long time. Years ago, I fell in love with the characters Sherlock and Savage. And it now seems that they are back. There was no magic, hocus-pocus or anything like that. It was just a good mystery and good relationship book. I really enjoyed the book. Often when I’m listening to a book that has a bunch of goofiness in it, I sit and mimic the narrator by going blah blah blah. I didn’t do that this book. I just enjoyed it and am ready for the next one.
