Book Reviews: Prank?

I need your opinion. Click here to see a book at Amazon.uk and scroll down to the Customer Reviews. There are three reviews by "A reader" from three different towns. All three are in a similar style (possibly fitting the description Pooterish). I suspect that the three reviews were all written by the same person and are tongue-in-cheek. Or do English people really, seriously write things like "My family know me as a man of few words and modest means", "they had given the Germans what they deserved having started the war in the first place" and "Imagine the authors implore us, you are over the Third Reich, land of evil, and it is dark" ?
