This book is now my third Lisa Jewell, and in my eyes she can do no wrong. This book, like her others are immediately engaging. I read this as part of a buddy read where we parsed it into 4 parts, to read each week, but I just bowled right over that - I had to keep going! This is true even though I figured out whodunnit by the halfway point, there were still plenty of twists that I didn't guess, and I wanted to know what happened. Set in a relatively posh subdivision in the UK, you are introduced to a motley crew of characters, and true to the book's title, everyone seems to be watching everyone else's moves...Then someone turns up dead, and you don't even know who it is, much less who did it, until the end! You can finish this in a single sitting and be highly entertained!
