This week in TV sees the return of Anna Friel’s undercover detective and Fleabag's 'hot priest', Andrew Scott, narrates a Kenyan safari.
BBC Two, 6.30pm
A new “electrifyingly fast” quiz show presented by comedian Zoe Lyons sees six contestants compete across six speedy rounds.

A £3000 prize is up for grabs for those who make it to the endgame.
