While poor Bill's love life is scuppered by another unlikely VIP visit, a blind Doctor is having a While My Guitar Gently Weeps moment in the Tardis. But there's no time to brood: a pyramid has suddenly appeared in a potential warzone involving the Chinese, Russians and Americans.

This doomsday scenario with a dash of Stargate reacquaints us with a monastic monstrosities who nearly excommunicated our trio. It's a tense, zippy tale, which, with its simmering international relations, feels very "now". And even if it makes you shout at the Doctor's maddening behavior, it confirms how delightfully Peter Capaldi, Pearl Mackie(Bill) and Matt Lucas(Nardole) work as a team.
