This has nothing to do with the Wallace films per se, but back the original source, the novels.
When I was a kid I hit library book sales, all the way up to Ebay, to get the old books from the 1920's & 30's.
Now with Kindle it's easy.
Most are free, due to public domain. Got one edition with 25 novels for $1.99. People in Germany have tons to choose.
Also got a lot of Sax Rohmer's and Conan Doyle's for free too.
These books are cool to see how London was almost a hundred years ago.
