Slow Horses author shares a major update about the series' future after the surprise Season 7 renewal this week.

Of Down Cemetery Road, Herron said: "It stars Emma Thompson and Ruth Wilson. Morwenna Banks has written the series, and she's done a wonderful job. There's quite a lot of overlap in the teams that made Slow Horses and Down Cemetery Road, and what I've seen of it, which is only little bit, is looking absolutely tremendous."

The critically acclaimed thriller, which also stars Jack Lowden, Kristin Scott Thomas, Jonathan Pryce, and Saskia Reeves, has released a logline for season seven, revealing that Lamb and his Slow Horses will be "on the hunt to find and neutralise a mole at the heart of British Government before they can bring down the state."

Hailed as “undoubtedly the best spy series on television", the Apple TV+ hit drama is adapted from Mick Herron’s best-selling books - and series 7 of Slow Horses is based on Herron’s Bad Actors, the eighth book in the award-winning Slough House series.
