For the first time in Apple TV+’s SLOW HORSES series, two Mick Herron books are being used in Season 6 episodes. Joe Country (2019) and Slough House (2021) show the threats to the spies of Slough House both from evil mercenaries and bureaucratic enemies.

I thought SLOW HORSES, Season 5 was the best of the series. Could Season 6 be better? We’ll see. Apple TV+ releases one of the six episodes per week so it will take until the end of October to judge how good this new series is. GRADE: Incomplete but trending towards an A.
