IF ALL GOES WELL, by the time you’re reading this, Phoebe Waller-Bridge will find herself at a creative standstill. A self-imposed one, that is. When we meet in London, summer is drawing to an end, and Waller-Bridge is two days into filming the second season of Fleabag, the word-of-mouth TV hit whose first season elevated the 33-year-old writer, actor and producer to comedy prominence in 2016. (Fleabag was released on BBC Three in Britain and on Amazon Video in America.) Work on season 2, Waller-Bridge explains, will take her through the middle of autumn, after which, she says, she is going to take a break and spend time with her friends, “who have just been so supportive over the last four or five years and not minded that I’ve been under a duvet most of the time.”

Her words suggest a blue funk of inactivity, but in fact, Waller-Bridge means the precise opposite. Hers is not the Duvet of Indolence: “My bed is my office. That’s where I write. And the middle of the night, under my duvet, is when I think I write my best stuff.”

What’s emerged from beneath the duvet is some of the best television of the past three years, in an impressive quantity. Immediately before Fleabag, there was Crashing, another British comedy series she created, its six half-hour episodes featuring a group of twentysomethings who test one another’s nerves while bunking together in a disused London hospital. And this past spring, via BBC America, came Killing Eve, a mordantly funny espionage thriller for which Waller-Bridge served as head writer and showrunner.
