- James Callis says “the jury’s out” on Claude Whelan’s fate in Slow Horses season 6.
- Whelan was forced out as MI5’s First Desk at the end of season 5.
- The character reappears in Mick Herron’s eighth novel, but the show may take a new direction.
- New writers Gaby Chiappe and Ben Vanstone could change the tone of upcoming seasons.
Fans of Slow Horses are already buzzing with theories after the dramatic finale of season 5. James Callis, who plays the sharp yet often flustered MI5 boss Claude Whelan, has teased that his character’s future in the Apple TV spy series remains uncertain. Despite his departure from the top job at the end of the season, Callis believes there may still be more to come.
Claude Whelan’s Fall from Power
Season 5 closed on a tense note for Claude Whelan. After several chaotic missteps in handling a wave of terrorist incidents, he was removed from his position as First Desk. It marked the second time a leader of MI5 has been ousted, following Ingrid Tearney’s resignation back in season 3.
Whelan’s exit was both dramatic and telling. For a character once seen as a polished bureaucrat, the finale stripped away his authority, leaving him vulnerable and defeated. Yet in true Slow Horses fashion, where every downfall hides another layer of intrigue, viewers are left wondering if that really was his last appearance.
The Books Hint at a Return
Those familiar with Mick Herron’s bestselling Slough House novels, which inspired the series, know that Whelan’s story doesn’t end here. The character resurfaces in Herron’s eighth book, Bad Actors. However, the show has never been a direct adaptation of the novels. Instead, it uses them as a framework while carving out its own storylines and rhythms.
This creative flexibility means there’s no guarantee Claude Whelan will reappear in the same way he does in the books. The uncertainty has only grown with behind-the-scenes changes. Screenwriter Will Smith, who helped shape the tone of the series, is stepping aside. Gaby Chiappe will write season 6, while Ben Vanstone takes over for season 7.
Such changes could bring new directions and interpretations, making Claude’s potential comeback even more unpredictable.
James Callis Speaks on Claude’s Future
When asked about his character’s fate, James Callis kept things mysterious. “The jury’s out,” he said, adding that while he knows what happens in the books, the TV version might chart a different path.
“I know what happens in the novels, but the television show isn’t necessarily the books,” he explained. “One imagines a very different person emerging from all this. I don’t quite know if it would be a phoenix rising from the ashes, but there are certainly a lot of ashes.”
Callis’ words suggest that if Whelan does return, he won’t be the same man we last saw. His experience in season 5’s finale could leave him scarred, changed, and possibly seeking redemption, or revenge. That transformation could be fascinating to watch, especially in a series known for its mix of dark humor and moral ambiguity.
New Writers and New Directions
With two more seasons already confirmed, Slow Horses is showing no signs of slowing down. Apple TV’s decision to greenlight both season 6 and season 7 suggests confidence in the story’s longevity. Yet the arrival of new writers could shift the show’s tone in subtle ways.
Gaby Chiappe, known for her sharp dialogue and character-driven scripts, may bring a more introspective lens to the next chapter. Ben Vanstone, who takes over for season 7, could lean into the political and emotional fallout left in Whelan’s wake.
Whether Claude returns or not, his shadow will likely loom large over MI5’s corridors. His downfall might even serve as a cautionary tale or a setup for another power struggle within the agency.
Fans Await the Next Move
For now, Callis insists he has no inside information. “Future Claude? I can’t talk about, because I don’t know,” he said with a grin. That statement has only fueled speculation that the actor might be keeping secrets to preserve future plot twists.
Fans have grown attached to Claude Whelan’s mix of charm and incompetence, and many are hopeful that he’ll reappear in some form. After all, Slow Horses thrives on the unexpected, and characters rarely stay gone for good.
Until Apple TV releases more details, viewers will just have to wait to see whether Claude rises again or remains buried in the ashes of his downfall.
