In the latest instant New York Times bestseller in the Fox O'Hare series, FBI agent Kate O'Hare and charming criminal Nick Fox race against time to uncover a buried train filled with Nazi gold?from the #1 New York Times bestselling author Janet Evanovich.

Straight as an arrow special agent Kate O'Hare and international criminal Nick Fox have brought down some of the biggest bad guys out there. But now they face their most dangerous foe yet?a vast, shadowy international organization known only as the Brotherhood.

Directly descended from the Vatican Bank priests who served Hitler during World War II, the Brotherhood is on a frantic search for a lost train loaded with $30 billion in Nazi gold, untouched for over seventy-five years somewhere in the mountains of Eastern Europe.

Kate and Nick know that there is only one man who can find the fortune and bring down the Brotherhood?the same man who taught Nick everything he knows?his father, Quentin. As the stakes get higher, they must also rely on Kate's own father, Jake, who shares his daughter's grit and stubbornness. Too bad they can never agree on anything.

From a remote monastery in the Swiss Alps to the lawless desert of the Western Sahara, Kate, Nick, and the two men who made them who they are today must crisscross the world in a desperate scramble to stop their deadliest foe in the biggest adventure of their lives.
