Arg fisk drikke
Yes, even the crack agents of Sweden’s C-byrån intelligence agency hate the taste of the arg fisk drikke (‘angry fish shake’). …What, you’ve never heard of C-byrån? Yes, well, that would be the idea, wouldn’t it? The Swedes did an excellent job of sanitizing what little public history there is of the group, which is impressive. Normally you’d think that a World War II spy agency that was top-heavy with art historians and other academics, and who had Abwehr head Wilhem Canaris as an intelligence source, would trip the radar of certain researchers in the modern era. Then again, there were a lot of WWII and Cold War archives that got thoroughly sanitized before the Internet showed up and made copying things an exercise in triviality.
