Fans of the Apple TV+ spy drama Slow Horses were left reeling following the October 7, 2026, episode, which depicted the death of fan-favorite character J.K. Coe. Played by Tom Brooke, the enigmatic agent was killed during a violent knife fight in a service station bathroom, a departure from his fate in the original novels.
A Final Confrontation at the Service Station
The fourth episode of the sixth season, titled Lost and Found,
saw the conclusion of J.K. Chiappe noted that the characters shared a sense of camaraderie in those final moments, acknowledging that both understood the necessity of the fight.
While readers of Mick Herron’s Joe Country were aware that Coe’s death was a possibility, the onscreen execution differed from the source material. The show opted to maintain the broad story beats while changing the specific circumstances, providing the television adaptation room to create its own version of the character’s final moments. The death is definitive, and River later discovers his body with the music still blasting from the deceased agent’s headphones.

Tom Brooke’s Reflection on the Character’s Arc
Tom Brooke, who joined the cast in 2024, admitted he had complex feelings about the character’s exit. It was such a good death scene in the book that it was the first thing I talked about with the showrunner,
Brooke told Town & Country. I was like, ‘As long as we’re heading to that and we get to do that, this is great.’
I thought I was all right about it until I picked up Clown Town at the airport and I read two pages of it. I wouldn’t want to say I burst into tears, but I was like, ‘I can’t read this. I cannot engage with this world again because I’m not part of it.’ And then I was like, ‘Oh, maybe I’m not alright about it.’
Tom Brooke, Actor
Brooke also revealed that he contributed specific character details to the script. He proposed the idea of having Coe ask about pensions, and he suggested the use of a “push knife,a weapon he described as a
horrible, horrible thing,” which creator Will Smith incorporated into the script. Brooke noted that he saw Coe as a man who was finally beginning to open up and engage with others just as his story came to a violent end. He also expressed a personal sense of loss regarding the character’s relationship with Shirley Dander, played by Aimee-Ffion Edwards, suggesting that their connection was a dynamic that could have been explored further.

The Aftermath for Sid Baker and the Slough House Team
The episode’s fallout extends beyond the loss of Coe. River, who watched helplessly as they drove away with her, is now left to pursue the assassins alone. Meanwhile, Jackson Lamb, played by Gary Oldman, continues his own investigation, using Reece Nesmith as bait to draw Frank Harkness into a meeting. The high-stakes cat-and-mouse game between Lamb and Harkness—the latter portrayed by Hugo Weaving—was described as a standout moment for the series.
The Slough House team is reeling from the loss, a sentiment echoed by cast members who have seen several colleagues depart over the show’s history. Christopher Chung, who plays Roddy, noted that while losing a castmate is “devastating,” it is par for the course
for the ensemble. He emphasized that the presence of former actors, such as Kadiff Kirwan (Marcus) and Dustin Demri-Burns (Min), remains a part of the show’s “tapestry.”
As the series moves toward its final two episodes, with new installments debuting on October 14 and October 21, the future of the remaining Slough House members remains uncertain. The investigation into the connection between the assassins, Frank Harkness, and media mogul Damien Cantor continues to drive the narrative, leaving the team to mourn the fallen while facing an opponent who seemingly holds the upper hand.
