Before Secret Agent (aka Danger Man) and The Avengers, etc., there was this 1952 TV show. I guess it lasted only one 39-episode season, but it's worth watching, partly for the Cold War nostalgia. At this writing it is streaming for free on Tubi TV. I'm going to record all 39 episodes to my computer's hard drive as mp4 files using my Play On Windows server, that automatically removes the annoying commercials that the ad-supported Tubi inserts.
