They built their own treasure maps from scraps and hints: the diary of a Louvre curator who secretly tracked Nazi plunder through the Paris rail yards; records recovered from bombed out cathedrals and museums; overheard conversations and behind-enemy-lines interviews; a tip from a dentist while getting a root canal. They started off moving in different directions, but ended up heading for the same place at the same time: the Alps near the German-Austrian-Italian border in the last two weeks of the war, where the great treasure caches of the Nazis were stored: the artwork of Paris, stolen mostly from Jewish collectors and dealers; masterworks from the museums of Naples and Florence; and the greatest prize of all, Hitler's personal hoard of masterpieces, looted from the most important art collections and museums in Europe and hidden deep within a working salt mine - a mine the Nazis had every intention of destroying before it fell into Allied hands. How does the Greatest Treasure Hunt in History end? As is often the case, history is often more extraordinary than fiction.
