Art critic Alastair Sooke delves into the murky world of art theft. Despite the high stakes - and often daring - involved, many cases are shrouded in mystery and go unnoticed by the media. Around 47,000 works of art are reported missing each year, yet it is only the heists involving the world's most valuable paintings that hit the headlines. But high-profile or not - once gone, the works are rarely recovered. Alastair meets one of America’s most notorious art thieves, Myles Connor. Connor was one of the FBI’s earliest suspects in the Gardner heist – but he had the perfect alibi: he was in jail in Chicago on the day of the heist. Nevertheless, Connor claims inside knowledge of the heist and Alastair is keen to hear what he has to say.
