Apple TV+ has announced the order of a fifth season See-Saw’s spy drama Slow Horses, following its season three finale.

In season five of Slow Horses, “everyone is suspicious when resident tech nerd Roddy Ho has a glamorous new girlfriend, but when a series of increasingly bizarre events occur across the city, it falls to the Slow Horses to work out how everything is connected. After all, Lamb knows that in the world of espionage, “London Rules” should always apply.”

Season five will be adapted from the next novel in the CWA Gold Dagger Award-winning Mick Herron “Slough House” book series.

Gary Oldman again stars as Lamb, the brilliant but cantankerous leader of the spies. The ensemble cast includes Kristin Scott Thomas, Jack Lowden, Saskia Reeves, Rosalind Eleazar, Christopher Chung, Samuel West, Sophie Okonedo, Aimee-Ffion Edwards, Kadiff Kirwan and Jonathan Pryce.

The series is produced for Apple TV+ by See-Saw Films and adapted for television by Will Smith. Will Smith, Jamie Laurenson, Hakan Kousetta, Iain Canning, Emile Sherman, Douglas Urbanski, Gail Mutrux, Julian Stevens and Graham Yost serve as executive producers on the series. The director for season five has not yet been announced.

The complete first three seasons of “Slow Horses” are now streaming on Apple TV+. Season four was announced in 2022.
