The death of J.K. Coe in Slow Horses Season 6, Episode 4, titled “Lost and Found,” brought a definitive and brutal end to one of Apple TV+’s most enigmatic spies. For actor Tom Brooke, who played the socially withdrawn MI5 agent since Season 4, the character’s final sequence was the result of a multi-season collaboration with the creative team to properly honor Mick Herron’s source material.
From the moment Brooke joined the hit espionage drama, he knew how he wanted Coe’s arc to conclude. Long before cameras rolled on Season 6, the actor had approached the production team to pitch adapting Coe’s final book scene from Joe Country. During his very first conversation with former showrunner Will Smith in Season 4, Brooke made his intentions clear.
“The first conversation I had with Will Smith in Season 4, I said, ‘I want to do the scene in the book when he dies,’” Brooke recalled. “And he said, ‘You’re going to have to wait, because that’s not going to happen now, but thank you for your interest.’ I was like, ‘That’s cool, but if there’s going to be an arc, if there is going to be a journey, it has to end with that.’ And he was like, ‘It will. So I’ve always had that scene in my head… It was so cool, and it was so Coe.’”
Shaping the Bathroom Showdown With Jim
In “Lost and Found,” that long-awaited vision comes to life during a tense encounter in a public restroom. Coe finds himself face-to-face with Jim, a Russian GRU assassin played by Kyle Soller, who is hunting the remaining Slow Horses alongside his partner Jane (MyAnna Buring).
Rather than cowering in fear, Coe approaches the confrontation with eerie calm. He accurately identifies Jim’s military background, questions his hit list, and eventually flashes his signature push knife-a prop Brooke originally campaigned to introduce back in Season 4. What follows is a messy, destructive tile-smashing brawl that wrecks the restroom before Jim delivers a fatal stab wound to Coe’s stomach.
Unlike the original novel where Coe kills his opponent, the television series chose to let Jim survive, creating a different emotional weight for the sequence. Co-executive producer Gaby Chiappe praised the collaboration behind the scene, noting that Brooke had a clear idea of how the interaction should feel. He treated the two killers as professional peers who shared an unspoken, companionable understanding before violence broke out.
Before the episode concludes, River Cartwright (Jack Lowden) discovers Coe slumped against the wall with his headphones blasting underground hip-hop. It is a fittingly stoic farewell for an agent defined by his silence and his reliance on music to cope with severe PTSD.
Reflecting on Coe’s Silence and a Potential Prequel
Reflecting on his time in Slough House, Brooke admitted that what he will miss most about playing Coe is the lack of dialogue. Coming from a theatrical background filled with long speeches and complex language, the challenge of conveying inner turmoil through minimal lines and physical stillness proved uniquely rewarding.
“The not talking. I really, really loved not talking,” Brooke said. “I’ve always wanted to do a part where you don’t say much… So to get to play the opposite was really, really special.”
With Coe officially written out of the narrative, speculation has naturally turned toward whether the character could return in some fashion. Since author Mick Herron has explored Coe’s life before Slough House in novels like The List and Nobody Walks, Brooke expressed enthusiasm when asked if he would consider reprising the role in a Better Call Saul-style spin-off.
“It would be an absolute blast,” Brooke said. “It would be so cool to show pre-Coe.”
While no official prequel has been greenlit by Apple TV, Brooke’s dedication to the role-evidenced by his real-world immersion in Coe’s underground hip-hop soundtrack and meticulous attention to book details-ensures that the quiet misfit will remain a standout figure in the Slow Horses legacy.
