Fans are eagerly awaiting news about the fifth season of the hit Apple TV+ spy series “Slow Horses” after its gripping season 4 finale. The season conclusion delivered a shocking revelation: Frank Harkness, played by actor Hugo Weaving, is revealed to be the biological father of River Cartwright, portrayed by Jack Lowden. While not confirming his involvement, Weaving has offered some intriguing insights about the potential return of his character, Frank Harkness.
When asked recently about a comeback, Weaving remained coy but noted that those familiar with the source material – Mick Herron’s novels – may have clues about what’s ahead. “I can’t really talk about that,” Weaving stated, “but suffice to say people who have read the books knows that Frank does return.” His comments imply Harkness’ story isn’t over, aligning with his character’s depiction in Herron’s later novels where he makes another appearance.
Weaving went on to praise Lowden’s performance as River and expressed interest in further exploring the developing relationship between their complex characters. “It was a real pleasure working with him,” Weaving remarked of Lowden. The finale saw Harkness successfully blackmail British security services for his release, opening the door for future showdowns. With a newly revealed familial tie to River now established, viewers can expect season 5 to delve deeper into themes of loyalty, betrayal and moral ambiguity within the world of espionage.
When asked about a potential Harkness spin-off, Weaving responded enthusiastically. “I’m excited about the prospect of revisiting Frank, and in whatever guise that is,” he stated. As fans await news of season 5, it’s clear the introduction of Harkness’ connection to River raises the stakes for the acclaimed series. “Slow Horses” continues to adapt Herron’s novels through compelling character stories set within the tense realm of international espionage.
