I read the book “Double Cross” by Ben McIntyre. That’s gives the full story of Garbo and all the other double agents who helped the British fool the Nazis about D-Day. The British tried to convince the FBI to use double agents, but Hoover was more intent on throwing spies in prison or having them executed. The Brits, who were better than Americans at spy intrigue, thought it was more worthwhile to have double agents and try and fool the Germans. It was a risky plan, because at any time a double agent could become a triple agent. But in the end it worked.

There was a time when America took pride in not engaging in European treachery. If you dealt with us, you knew what to expect. A lot to be said for that. Not so much today,,,
We have lost a lot as a nation because of a century of deep engagement and alliance with the UK and Europe. That dogs, fleas thing.
The Germans had a bigger and better “double cross” system than the Brits. “ A life of secrets: Vera Atkins and the missing agents of WWII”- Sarah Helm
