What to expect in Slow Horses Season 5 Episode 6?

In the previous episode of Slow Horses, the terrorist plot to adopt UK’s own destabilization strategy against them is uncovered. Tara Younis, who was Roddy Ho’s girlfriend, is arrested by MI5 for her role in collaborating with the Libyan terrorist group. During the interrogation she initially reveals that she assisted them to keep herself safe.

However, Lamb is suspicious of Tara. When Emma Flyte pushes for more answers, Tara divulges that it was she who had given the idea of destabilization to the men, who turned out to be terrorists. Claude Whelan believes that Tara is just a pawn and insists on using her as a bait to catch the terrorists.

Tara agrees to help and a plan is set in motion. She wears a jacket with a tracker and microphone to meet them. However, she suddenly vanishes revealing that she was in fact a key member herself and managed to fool the MI5. Not just that, the code that she gave MI5 has shut down all the systems, making the department go blind. But Slough House is working to uncover every link possible to the impending attack.

Slow Horses Season 5 Episode 6 will see the investigation finally finding the mastermind orchestrating the destabilization plan against the UK. Tara’s history and her actual role in the whole plot will be unveiled. A larger conspiracy is in play, which will come to light in the finale episode with the Slough House and the other MI5 agents working together.
