Afirst look at the highly anticipated fifth season of Apple TV+’s hit espionage drama Slow Horses has been unveiled – and it looks dramatic.

Gary Oldman leads the cast in the hugely successful spy thriller, which is based on Mick Herron’s Slough House novel series and was first released in 2022. The award-winning actor plays Jackson Lamb, the talented but cantankerous leader of Slough House, the dumping ground of MI5 for spies who have made career-ending mistakes.

Alongside first look images, which includes one of a serious-looking Jackson Lamb in the midst of a phone call in a cafe, and another of a fearful looking Shirley Dander (Aimee-Ffion Edwards) and Catherine Standish (Saskia Reeves) standing in a dimly-lit street, Apple TV shared the release date for the new season.

Fans can tune into the first two episodes on Wednesday, September 24. New episodes will air weekly after that until October 22.

So, what can fans expect? Keep reading to find out more.
