#1 NEW YORK TIMES BESTSELLING AUTHOR

A heart-stopping new FBI thriller from New York Times bestseller Catherine Coulter.

After Special Agent Dillon Savich stops a crazy man from harming a pregnant woman, the man unexpectedly falls into a coma. Doctors discover a drug in his blood that they can’t classify. And his only identification is a yellow wristband marked E 2. Did this John Doe escape from a psychiatric hospital? And why was he at the pregnant woman’s house? When her newborn baby is kidnapped from the hospital, Savich realises there’s a connection between the kidnapping and the unconscious John Doe. DNA tests uncover a startling fact: his cells are unlike any other – he’s an enigma.

Agents Savich and Sherlock and an FBI team of experts must find the kidnapped baby, discover the link, and determine what bizarre drug was used on John Doe and, most importantly, why.
Meanwhile, Liam Hennessey, aka Manta Ray, a convicted bank robber, escapes from the federal marshals during his transport to a penitentiary. He and his ‘handlers’ are seen going into the Daniel Boone National Forest. Savich sends Agents Cam Wittier and Jack Cabot after them. Why break out this violent criminal? Or did the safe-deposit box he stole and hid before he was captured contain something critically dangerous? Wittier and Cabot are in hot pursuit.

What they discover turns the case sideways. Enigma will keep you guessing in this race against the clock until the shocking conclusions.
