Slow Horses season 3 will open in Istanbul rather than London in a major difference from Mick Herron's original novel, "Real Tigers", on which the hit Apple TV Plus series is based on.
While the book opens on a "damp, dark, foggy" weekday morning in London, the TV version will instead begin with a dramatic boat chase in Istanbul. There's no mention of Turkey in the opening of the novel and it will be intriguing to see how many other differences there are between the book and the series. We know, thanks to Herron, there's also a character in the TV version that's not in the book.
