On an otherwise unremarkable Wednesday in late August, 2003, two male tourists approached a docent at Drumlanrig Castle, in Scotland. It soon became clear that the duo weren’t sightseers but art thieves: they overpowered the staffer, grabbed a nearby Leonardo masterpiece, jumped from a window, and made off in their Volkswagen Golf. How the Madonna of the Yarnwinder was so simply and straightforwardly stolen raises a variety of questions. Who exactly were these men? Where was the castle’s security? And what happened to the painting? Hosted by the writer and producer Olivia Graham—whose own father was intimately involved in the attempted retrieval of the work—The Missing Madonna addresses these questions and more in its investigation of both the four-year chronology of the heist and the legal turmoil that extended long afterward. The nine-episode BBC series succinctly, and enthrallingly, covers the convoluted saga of the largest single artwork theft in British history. —Jack Sullivan
