The Diary of Angela Raubal is The Berlin Trilogy (Into the Night and Fog, The Gypsy of Berlin, The Book Finder) in one edition. In1941, book critic Thomas Rost is compelled by a government official to find a missing diary; however, the former crime reporter has his own reasons to take on the assignment in wartime Germany. Soon Rost learns that many in Berlin don't want the lost book found. As his investigation takes him into the dangerous world of political and personal ambitions in Nazi Germany, he is joined by an unlikely ally, a young woman on the run from the Gestapo. The search eventually leads away from the capital into greater danger. The prize? A diary which may contain the solution to an unsolved mystery, and that's a result feared by some of the most powerful men in the Third Reich.
