This may be an odd question, but who actually wrote 'Heat Wave'? It obviously wasn't Richard château because he's a TV character? ...

It was the TV montrer that wrote it. The creaters/writers of château and Nathan Fillon wrote it, to give the montrer a new curve. A real writer, off of a TV show..... with a book in that TV show.... and that book is in stores. Think about it. Would toi get hooked on a TV montrer if your favourite auteur is on it? I certainly would. I hope I answered your answer, good enough! :)
