I've long lauded "Slow Horses" as being one of the best shows on TV, if not the best. So "Slow Horses" season 5 has a high bar to clear to live up to my expectations for the Apple TV Plus British spy thriller. Unsurprisingly, not only did it clear that bar, but the season 5 premiere might be setting up the show's best season yet.
For those of you who haven't seen the "Slow Horses" premiere yet, here are all the details I can give you before getting into spoilers. Season 5 adapts Mick Herron's 2018 novel "London Rules," the fifth novel in the "Slough House" series. It centers around a series of terrorist attacks, including a mass shooting we see discussed in the official season 5 trailer and MI5 second-in-command Diana Taverner (Kristin Scott Thomas) has put Slough House in lockdown. The reason for this lockdown? Both she and Jackson Lamb (Gary Oldman) are suspicious about Roddy Ho's (Christopher Chung) dating life (namely, that it exists), and they both think his new girlfriend could be involved in the terror attacks hitting London.
