In 1993, two men hoist themselves down through a sawn-off hole in the roof of Moderna Museet in Stockholm. The men will receive eight works of art by, among others, Pablo Picasso and Georges Braque worth half a billion kronor.

At the home of one of the thieves' little brothers, three of the works are soon found and the three men are convicted. But five works are still gone. Moderna Museet's then head of security, Kjell Hestrell, and the dismissed national crime chief decide to use some unconventional methods to find them. Among other things, the famous bank robber Clark Olofsson is contacted.

Olofsson: "Know who had it last"

Eventually, the men get a tip and can pick up the paintings in a rental car. But one is missing – "The White Screen" by George Braque.

Today, Olofsson claims to have both stolen the painting from George Braque (twice) and sold it (three times).

"I'd give a damn about being able to find it if I put my mind to it, because I know who had it last," he told the SVT program "Sweden's largest art coup".

Kjell Hestrell, for his part, believes that Olofsson is making things up, but he himself has not let go of hope of finding the painting.
