Killing Eve really set the bar for BBC thrillers, didn't it? When the first episode aired in 2018, little did we know how obsessed we'd all become with Jodie Comer, Sandra Oh and the rest of the cast - including Harriet Walters.

She joined the show in series three to play Dasha Duzran, one of Villanelle's former mentors and handlers who attempts to regain control of the rogue assassin within the Twelve.

It was a dark and manipulative role, and one that Harriet played brilliantly, taking on the former Soviet Olympic gymnast who had a complex personal relationship with Comer's character with ease.

And if you didn't know, she's also exceptional in another BBC spy thriller called London Spy, which is available to stream on Prime Video. Here's everything you need to know about it, from storyline to wider cast and more.

What is London Spy?

The series centres around Danny, a free-spirited man in London who unexpectedly falls in love with a secretive man named Alex. But when Alex is found murdered, Danny begins to investigate what happened, and in turn uncovers a world full of secrets, lies, cover-ups and the intelligence service.

Harriet plays Clare, which is a relatively small role (she's in three episodes), but she really steals the show, bringing her elevated and commanding presence to the screen.

The Prime Video description reads, "London Spy is a gripping, contemporary, emotional thriller that tells the story of a chance romance between two people from very different worlds: one from the headquarters of the secret intelligence service, the other from a world of clubbing and youthful excess."
