This isn’t something that happens very often, but the TV series was a hell of a lot better than the book. Neither Villanelle or Eve were particularly well written. There seemed to be a lot of descriptive filler which made it a tad boring and it ended on a pointless cliff hanger. The main plus is that it’s a short read so I got through it pretty quickly. I'd definitely skip the book and just watch the show though if I was you.
