Whatever else is going right or wrong with a TV show, it helps if we know immediately which series we’re watching. A shimmering brutalist landscape, “Russia”written in giant pastel letters, retro-reverb beehive pop on the soundtrack and a woman in biking leathers breaking into a government building wielding a gun and silencer? This can only be Killing Eve (BBC iPlayer).
This is season four. If you didn’t catch seasons one to three, what have you missed? Well, there’s a diffident but determined intelligence agent called Eve (Sandra Oh), and a fearsome yet brittle assassin called Villanelle (Jodie Comer), and they’re obsessed with each other because … actually we’ve never fully established why. Anyway, since Eve began tracking Villanelle, what has happened is … do you know, I’m not properly across that either? A criminal network called the Twelve keeps murdering beloved minor characters, and Eve plans to destroy it, but what the Twelve wants or why we might care has remained murky.
