The tv show Castle has become one of my guilty pleasures. It's showing on Alibi on Wednesdays at 9pm. It's along the lines of The Mentalist with a (male) outsider coming in and showing the (female) detective and her team how it's done. In this case Rick Castle is a best-selling crime writer.
I recently found out that there are books being published as if they were written by Rick Castle - the ones that he is writing in the show, his Nikki Heat series. (Almost as confusing as how there are Bones books based on the tv series, which are based on the books by Kathy Reichs.)
In the trailer below, Stephen J Cannell and Michael Connelly join in the fun:
Update: You can read the first ten chapters of the first book in the series, Heat Wave, at the Castle website.
