Now my track record with Jo Baker isn't great, so why did I read this...because I have a disturbing obsession with books about the Blitz? And this started off as just that, a sort of slice-of-life war novel and I was doing pretty well with it. Then it started to veer off in a weird way. Is this about a serial killer? Then suddenly our main character is in the looney bin, and that was most unpleasant to read. Was everything that happened before imagined or something? How unreliable is our narrator, anyway? Wait, is it a SPY novel? Huh? I have no idea what this book wanted to be. But at least it only had one timeline, I guess we can be thankful for that.
