What is season 5 about?
Season 5 adapts Mick Herron’s London Rules, the next novel in his Slough House series. Apple’s synopsis begins with suspicion among the team after resident tech specialist Roddy Ho gets a glamorous new girlfriend. As increasingly bizarre events unfold across London, the Slow Horses try to work out how the incidents connect. Jackson Lamb’s stated rule is to “cover your back.”
The story’s starting point is Roddy’s relationship; the larger mystery is how the strange events across the city fit together. The source novel is identified in Apple’s season announcement.
