Peacock's Ponies introduced a multitude of twists and turns - but how did the show end after the mole was revealed and a character's death was walked back? The show, which premiered earlier this month, follows two secretaries in 1977 who are working at the American embassy in Moscow before becoming CIA operatives after their husbands die under mysterious circumstances. Emilia Clarke and Haley Lu Richardson star in the series, which also includes Adrian Lester, Artjom Gilz, Nicholas Podany, Petro Ninovskyi and Vic Michaelis.
