The International Spy Museum's Spycast is a podcast which features author interviews and lectures relating to the history of espionage. There are 11 audio podcasts specifically related to World War II. However, for those who have a general interest in espionage, there is plenty of variety. One possible criticism is that it does tend to be OSS/CIA heavy, though there are some podcasts that feature British Intelligence.
