Netflix smash Behind Her Eyes: Sarah Pinborough on writing 'that ending' | Books | The Guardian

Now the novel is a hit Netflix miniseries and Pinborough is still boggled by her own twist. "I finished watching it and then I had a shower and went to bed and I was still thinking, ‘That ending, man!' - and I made it up!" she says, speaking from her home near Milton Keynes. "But it's different seeing it."

Behind Her Eyes is the story of Louise, played by Simona Brown, a single mother who has a one-night stand with a man in a bar, only to discover that he is her new boss, David, played by Tom Bateman. Louise's new friend Adele (Eve Hewson) also happens to be David's wife. As Louise gets to know the couple, she sees the cracks in their marriage widen. So far, so run of the domestic noir mill. But Pinborough made her name in horror and science fiction before she turned to thrillers - so when the big reveal comes, Behind Her Eyes is genuinely #WTFthatending.
