Ghent Altarpiece
The original lower left panel known as The Just Judges was stolen in 1934. The original panel has never been found.  It was replaced by a copy made in 1945 by Jef Vanderveken.  The stolen panel plays a big part in Albert Camus' novel La chute. In 2010 Dutch journalist Karl Hammer published "The secret of the sacred panel".  He describes the involvement of various religious groups, the Vatican and British intelligence services in their attempt to get back the lost panel.
