Haven of Vipers

Mason Collins investigates a rash of murders only to discover a web of co-conspirators more dangerous than anything he's ever encountered, in a case that will take him from a Hollywood-style nightclub and a speeding train, to the icy slopes of the Bavarian Alps. When the Third Reich collapsed, the small town of Garmisch-Partenkirchen became the home of fleeing war criminals, making it the final depository for the Nazis' stolen riches. There are fortunes to be made on the black market. Murder, extortion, and corruption have become the norm.
It's a perfect storm for a criminal investigator like Mason Collins, who must investigate a shadowy labyrinth of co-conspirators including former SS and Gestapo officers, U.S. Army OSS officers, and liberated Polish POWs.
As both witnesses and evidence begin disappearing, it becomes obvious that someone on high is pulling strings to stifle the investigation-and that Mason must feel his way in the darkness if he is going to find out who in town has the most to gain-and the most to lose...
