'Slow Horses' season 4 has been really good so far. Of course, that's no surprise. I've been calling it the best show on TV for years, and its previous seasons have merited a binge-watch from more than one of the Tom's Guide staff. Our streaming editor even called episode 1 of this season her "favorite premiere of the year."
But we're through most of this season after episode 5 last night, and there's only the season 4 finale next week. The whole season has been building to a big reveal that I didn't expect when the season started and for some reason — despite everyone in the world of "Slow Horses" seeming to know — they just won't drop what should be the biggest bombshell in the show's history.
