In Lebensborn, the second book in The Addlestone Chronicles trilogy, the two English couples are working for the Secret Services sections MI5 and MI6. While in Munich, they rescue Johann Sherman, an economist who had been removed from his position as a university professor for simply being a Jew. Together, they go to London where Johann offers to share his knowledge of the Nazi regime with senior UK cabinet ministers. At the meeting, identifies a number of spies who have infiltrated British institutions.
This is an excerpt from Lebensborn: “Johann says, I expect you’ve heard of Gabrielle Chanel who likes to be called Coco. The owners of her company, Parfums Chanel are the Wertheimer family who are themselves Jewish. As an Aryan, she’s been selected to be the outward face of the company in Nazi Germany. You’re probably aware from the British press, she has a long-established romantic liaison with Hugh Grosvenor, 2nd Duke of Westminster, one of the wealthiest men in the world. The Duke is currently on his third marriage and at the same time, is conducting this very public affair. I have to tell you, Coco is a German spy. The Abwehr has registered her as agent F7124. She passes on information that she is able to obtain from the Duke and his political and business connections.”

So, let’s see…A wealthy, politically well-placed, and thrice married man, while conducting a very public affair, finds himself in a position to pass on sensitive information to the enemy. Anything familiar with this scenario?
