In Priceless, Robert K. Wittman, the founder of the FBI's Art Crime Team, pulls back the curtain on his remarkable career for the first time, offering a real-life international thriller to rival The Thomas Crown Affair.

Rising from humble roots as the son of an antique dealer, Wittman built a twenty-year career that was nothing short of extraordinary. He went undercover, usually unarmed, to catch art thieves, scammers, and black market traders in Paris and Philadelphia, Rio and Santa Fe, Miami and Madrid.

In this page-turning memoir, Wittman fascinates with the stories behind his recoveries of priceless art and antiquities: The golden armor of an ancient Peruvian warrior king. The Rodin sculpture that inspired the Impressionist movement. The headdress Geronimo wore at his final Pow-Wow. The rare Civil War battle flag carried into battle by one of the nation's first African-American regiments.

The breadth of Wittman's exploits is unmatched: He traveled the world to rescue paintings by Rockwell and Rembrandt, Pissarro, Monet and Picasso, often working undercover overseas at the whim of foreign governments. Closer to home, he recovered an original copy of the Bill of Rights and cracked the scam that rocked the PBS series Antiques Roadshow.

By the FBI's accounting, Wittman saved hundreds of millions of dollars worth of art and antiquities. He says the statistic isn't important. After all, who's to say what is worth more --a Rembrandt self-portrait or an American flag carried into battle? They're both priceless.

The art thieves and scammers Wittman caught run the gamut from rich to poor, smart to foolish, organized criminals to desperate loners. The smuggler who brought him a looted 6th-century treasure turned out to be a high-ranking diplomat. The appraiser who stole countless heirlooms from war heroes' descendants was a slick, aristocratic con man. The museum janitor who made off with locks of George Washington's hair just wanted to make a few extra bucks, figuring no one would miss what he'd filched.

In his final case, Wittman called on every bit of knowledge and experience in his arsenal to take on his greatest challenge: working undercover to track the vicious criminals behind what might be the most audacious art theft of all.
