Edvard Munch's "The Scream" was stolen from Norway's National Gallery in 1994. The Norwegian police turned to Scotland Yard's specialist art and antiques squad for help, who set up a complex sting to retrieve the painting. Undercover detective Charley Hill posed as a representative of the Getty Museum, who arranged a series of meetings to buy back the picture. While it was finally retrieved and the thieves captured, they were later freed on a legal technicality : Hill had entered Norway with a false passport, and his evidence was inadmissible.
