Spy Thriller for Noirvember

We are in the heart of Noirvember, so I am checking for potential future reads. And I don't have to stick with crime fiction: once I am done with my current read, I have a few spy novels on my TBR list. One of them is Jack Beaumont's The Frenchman. I know nothing about it, except that the hero works for the DGSE, the French secret service. And I thought it would be a nice to have a thriller where the protagonist isn't from the CIA or MI6, or a mix thereof. And apparently, it's part of a series. If anyone among you read it, or indeed anything from Beaumont, please let me know.
