What if Hitler had won the war?

It is April 1964 and one week before Hitler's 75th birthday. Xavier March, a detective of the Kriminalpolizei, is called out to investigate the discovery of a dead body in a lake near Berlin's most prestigious suburb.

As March discovers the identity of the body, he uncovers signs of a conspiracy that could go to the very top of the German Reich. And, with the Gestapo just one step behind, March, together with an American journalist, is caught up in a race to discover and reveal the truth - a truth that has already killed, a truth that could topple governments, a truth that will change history.
