What's the biggest thing you've ever stolen? An office biro? The extra change you were accidentally given by a shopkeeper? In the audacity stakes, art thieves don't mess around with the small stuff, and this series uncovers some of the world's most audacious and expensive art thefts. All of a sudden those Post-It Notes won't seem so bad.

Heard the one about the raid where masterpieces by Renoir and Rembrandt worth around $80 million were stolen in broad daylight from the Swedish National Museum in Stockholm? Or the one about the thieves who made off with $500 million worth of art from a gallery in Boston, in just one single night?

These might sound at best like the plots for high-octane films, or at worst, the opening lines of very bad jokes, but they are all true stories of daring and audacious art robberies.

The Art of the Heist is a revealing series which examines some of the greatest art thefts of our times, re-stages the robberies, and follows the story to find out what happened in the end. While a surprising number of works of art are traced and recovered in elaborate sting operations over the years, many are not, which has led in turn to intriguing - and occasionally ludicrous - conspiracy theories...
