Points for creativity because I found the device of a "book within a book" kind of fun. The first few notes from the American reader to the Aussie author highlighting cultural differences and local details that might need to be edited for accuracy was also fun. As someone who has spent a lot of time in Back Bay Boston, I enjoyed all the details related to the setting. Once the novelty of this approach wore off, I was left holding a clumsy whodunnit with strangers who bonded too quickly to be realistic and were all too eligible to ride the Suspect Carousel. As a beach read thriller, it did the trick, but don't go looking for a complex mystery here.
