If you enjoy Le Carré and haven't checked out the Slough House series (novels and mini series on Apple TV) you're in for a treat. It's not exactly Le Carré, but it's definitely Cold War caliber spy fiction set in the present day with a very Smiley-esque old spy master and a budding young spy who is learning to think like a Smiley rather than act like the Bond he's been trained to be.
