Slow Horses star Christopher Chung revealed a huge change for his character, Roddy Ho, in the upcoming fourth season of Apple TV+'s hit espionage drama. 

For those unfamiliar with the show, which is based on Mick Herron's Slough House novel series, it follows a group of misfit intelligence agents who have all committed career-ending mistakes and subsequently banished to the dumping ground department of MI5.

"It's a great storyline for Roddy. He gets a girlfriend," revealed the 35-year-old, adding: "That's all I'll say."

As for the plot, season four will open with "a bombing that detonates personal secrets, rocking the already unstable foundations of Slough House". 

The new episodes, which have already been filmed, will draw on Mick Herron's novel, Spook Street. In the book, River's grandad, retired agent David Cartwright, becomes a target when he forgets that secrets are supposed to stay hidden.

"Now, far from joining the myths and legends of Spook Street, River Cartwright is part of Jackson Lamb's team of pen-pushing no-hopers at Slough House," the book synopsis continues. "Which doesn't mean he won't ditch everything and go rogue when his grandfather comes under threat.

"Lamb worked with Cartwright back in the day, and knows better than most that this is no innocent old man. So when a panic button raises the alarm at Intelligence Service HQ, it's Lamb who's called on to identify the body. And it's Lamb who'll do whatever's necessary to protect an agent in peril."

While a release date has yet to be announced, it's thought that the series will return before the end of 2024.
