I'm a huge fan of the Jack Reacher series and have avidly read all of the previous ones: he'd normally get 5* from me. But I found this one disappointing - in fact it's so much so that I wondered if it's a collaboration with another less accomplished writer. Not so apparently. There's too much detailed description of driving through London and building layouts and too little action. I hope this is just a blip and Lee Child will return to his usual exciting story telling.
