Let me begin by saying that I am a fan of the CASTLE television series. It is a cheeky, and sometimes cheesy bit of fluff that is pure entertainment. The viewer is not supposed to examine the "facts" of each weekly offering too closely nor try to utilize logic. This is just a show where you sit back and enjoy the silly banter of the cast and the sexual tension exuding from the two protagonists as they attempt to solve their latest case.
HEAT WAVE capitalizes on the popularity of the television show and follows the same formula that made the show a success. Unfortunately, what plays well on the small screen does not necessarily translate to the page with the same panache.
While the book does have a couple of amusing exchanges between our two protagonists, I believe if one has never seen the show and has no point of reference, this story of the murdered real-estate tycoon and his trophy wife would have found its way to the "remainders" bin within a month of publication.
My recommendation: If you want to be entertained for an hour, sit back and watch the show, pass on this book and devote your time to more informative and interesting reading material. If you feel compelled to read this offering, save your money and get it at the library.
