With its third season, Apple TV+’s spy drama “Slow Horses,” based on Mick Herron‘s series of spy novels, doles out the smallest revelations about Jackson Lamb, the head of Slough House, played by Gary Oldman. “Another layer of the onion is peeled back,” says Oldman, whose Lamb doesn’t mind that the world sees him as a slovenly, flatulent insult hurler leading a team of failed operatives.
