A New York policeman is charged with finding a Jew who is reported to have suddenly appeared in the city decades after all Jews are thought to have been exterminated. There is a reference to a kind of second Wannsee Conference, held at Buckingham Palace in German-occupied London after the extermination of European Jews had been completed, setting up the extension of the Final Solution to the rest of the world; the last few hundred Jews are mentioned as having been discovered and killed by relentless Einsatzgruppen hunters in 1964, having hidden at the ruins of Angkor Wat in Cambodia. There is a Cold War between the former Axis Powers allies, Germany and Japan, both of whom have nuclear weapons and are engaged in an arms race akin to that between the United States and Soviet Union in our own timeline.
