The Book Finder, an historical novel, is the third part of the Berlin Trilogy. Thomas Rost and his companion Ingrid had to leave the capital in a hurry. Traveling to Dresden for information on the lost diary results in more trouble, so on to Prague and into even greater danger. Finally, Munich beckons with the promise of the prize, but can they then escape or will they face imprisonment or death in wartime Germany? Some of the answers are found in a follow-up to The Berlin Trilogy: Stella by Star Light.
