The 2-minute-14-second video exhibits Lamb's dialogue deliveries, his dark humours, and his intelligence. The trailer reveals that the team will be investigating a shocking case after discovering 11 dead bodies, making the city go under lockdown.

The video hints that as the team digs deeper, they realise these seemingly unrelated dead bodies might be connected in a surprising way to a new woman who has entered their espionage world as the alluring lover of one of the Slow Horses spies, Roddy Ho (Christopher Chung). The season follows Lamb and his team as they try to unravel this mystery.

The show's writers clearly know that nothing amps up the suspense theme quite like a betrayal from within, proving that some classic spy games never go out of style!
