I have a tendency to get lost in my research for the book, and yet finding primary sources (Germany newspapers, diaries, or magazines) from 1938 Germany has been a little harder than I expected. Lots of information is available about the war itself, especially from the American viewpoint, but that prewar period in Germany is a bit harder to come by.
Last week, I spoke with the librarian at the Abington Library about finding some additional primary sources for details I need to set up the historical accuracy of my finale. She had a great suggestion for primary sources: video. She suggested going to the US Holocaust Museum website as well as Google videos and use my typical search terms -1938 Munich- and see what kind of hits I got. I tried it and Bingo. I found some actual footage of parades - in color! Amazing.
Seeing a Nazi-era parade in living, moving detail will make my description of it more accurate. It also helps me see how to fit Sophie's climatic scene into it in a way that will be logical and exciting.
