Shortly after midnight on March 18, 1990, two men broke into the Isabella Stewart Gardner Museum in Boston and committed the largest art heist in history. They stole a dozen masterpieces, including one Vermeer, three Rembrandts, and five Degas. But after thousands of leads, hundreds of interviews, and a $5 million reward, not a single painting has been recovered. Worth as much as $500 million, the missing masterpieces have become the Holy Grail of the art world and their theft one of the nation's most extraordinary unsolved mysteries. Art detective Harold Smith worked the theft for years, and after his death, reporter Ulrich Boser decided to pick up where he left off. Traveling deep into the art underworld, Boser explores Smith's unfinished leads and comes across a remarkable cast of characters, including a brilliant rock 'n' roll art thief and a golden-boy gangster who professes his innocence in rhyming verse. A tale of art and greed, of obsession and loss, "The Gardner Heist" is as compelling as the stolen masterpieces themselves.
