Perhaps you have started eyeing your thermostat, thinking about inching the heating up. Possibly you’ve seen the green of tree leaves becoming tinged with brown. Maybe you’ve noticed Halloween decorations in Tesco or seasonal favourites returning to Starbucks. Or, among all these perennial harbingers of autumn’s return, it’s conceivable that it is the reappearance of Slow Horses, Apple’s beloved adaptation of Mick Herron’s spy novels, that tells you that summer is over.
Remember Struan Loy (Paul Higgins), the sad sack agent who was fired by Jackson Lamb (Gary Oldman) in the show’s first series? Returning – briefly – at the start of the sixth season, Loy meets his maker in a manmade inferno that raises a few questions. “It seems somebody is killing Slow Horses,” observes Catherine Standish (Saskia Reeves). What have these off-the-books misfits done to attract the attention of two Russian assassins? And why does it seem like Diana Taverner (Kristin Scott Thomas) has scrubbed all trace of their existence from the records? They face a race, against both time and foreign powers, to save their former agents and uncover the truth.
