Escape to the Thirties
This is a good time to examine the 1930s, even in novels.
A good start is the work of Alan Furst. One example of his ability to create an ominous atmosphere is The Foreign Correspondent. Great escape reading.
[BTW: I recently read an economic writer who dismissed concerns about terrorism as foolish. Hmm. Should Daladier have worried more about French unemployment or about Germany?]
