Exiles Return

 
The novel begins with Professor Kuno Adler, who is Jewish and fled Vienna after the Anschluss (the events of March 1938 when Hitler's troops marched into Austria). He is returning from New York to try and take up his old life as a research scientist. We realise through his confrontation with officialdom and with the changed fabric of the city (the lime trees are there no longer, it is hard to know who behaved well during the war and who was a Nazi sympathiser) that a refugee who goes back has a very difficult time.
