New York Times best-selling author Nelson DeMille returns with another heart-pounding John Corey thriller—this time including Corey’s FBI agent wife Kate Mayfield...and their mission is to catch an elusive terrorist mastermind before he catches them.

Anti-terrorist Task Force agent John Corey and his wife, FBI agent Kate Mayfield, have been posted overseas to Sana'a, Yemen—one of the most dangerous places in the Middle East. While there, they will be working with a small team to track down one of the masterminds behind the USS Cole bombing: A high-ranking Al Qaeda operative known as The Panther. Ruthless and elusive, he's wanted for multiple terrorist acts and murders—and the US Government is determined to bring him down, no matter the cost. As latecomers to a deadly game, John and Kate don't know the rules, the players, or the score. What they do know is that there is more to their assignment than meets the eye—and that the hunters are about to become the hunted.

Filled with breathtaking plot turns and told in John Corey's inimitable voice, The Panther is a brilliant depiction of one of the most treacherous countries in the world and raises disturbing questions about whether we can ever know who our enemies—or our allies—really are.
