Thriller-starved viewers looking for an exciting show to obsess over, look no further than Slow Horses. According to a story by A.V. Club, the Jon Le Carré-inspired spy series has been renewed by Apple TV for a third and fourth season before the upcoming second season has even premiered. Expected to drop later down the line this year, there is not currently a release date for the show’s anticipated second season at this time.

The series is based on a series of books by author Mick Herron, and draws inspiration from works such as Tomas Alfredson’s (The Snowman) Tinker Tailor Soldier Spy and other more grounded works that feature espionage. Gary Oldman (The Dark Knight), who starred in the aforementioned film, also stars in Slow Horses, which further lends to the desired aesthetic of the series. Aspiring to offer an alternative spy tale to the classic albeit unrelatable James Bond movies, the agents struggle with inhibition and are placed in a defunct agency for MI5 operatives with colossal missteps under their belts, hence the title Slow Horses.

The A.V. Club also summarized the series’ first season, saying:

“Slow Horses’s first season is chock full of characters, lines, and moments that will work brilliantly for fans of spy thrillers—not gritty spy thrillers, not action-packed spy thrillers, but straight-laced, classic, by-the-book ones. There are more episodes on the way (and more books to adapt). But for now, this conventional addition to an already crowded genre counts as a confirmed kill.”

There is no new information regarding the second season’s release at this time.
