https://theintercept.com/2015/12/25/gchq-play-a-british-spy-game/ British intelligence releases a Christmas puzzle every year. This is one from 2006, released in the Snowden Docs. I thought y'all might enjoy a real bonafide spy puzzle. Answers will be published in January. I'll post the followup link then. Enjoy!
Lol, yes I should've been more clear. This is an internal one that is not released to the public, ie for real spies only.Supposed to be a little harder and I found it pretty interesting.
