River’s still reeling from the aftermath of jumping on his dad’s car the appearance of his father at the funeral on Slow Horses Season 6 Episode 2, “Daddy Issues.” It’s unclear what exactly Frank is doing back in town, but it definitely was not to pay his respects to River’s grandfather.

Meanwhile, another slow horse has turned up dead, prompting even more suspicion from Lamb and Slough House. Our favorite spies need to work quickly because it is only a matter of time before the killers take out their next target.
