In April 1945, the Nazis, reeling and near defeat, frantically work to hide the huge store of art treasures that Hitler looted from Europe. Truck convoys loaded with the cultural wealth of the Western world pour in an unending stream into the compound of the vast Altaussee salt mine high in the Austrian Alps. But with the Allies closing in, the vaunted efficiency of the Nazis has broken down. At Altaussee, all is tumult and confusion. In the commotion a single truck, its driver, and its priceless load of masterpieces vanish into a mountain snowstorm. Half a century later, in a seedy Boston pawnshop, ex-curator Ben Revere makes a stunning discovery among the piles of junk: a Velazquez from the legendary lost truck. But with it comes decades of secrets, rancor, and lies, and the few who know of the painting`s existence have their lives snuffed out by an unknown assassin. Revere must travel back to the grand cites of Europe to unravel the tangled history of the lost truck and its treasures before fifty years of hatred, greed, and retribution catch up with him.
