To answer your question, Jackie, yes and no. Or should it be yes? Well, you decide.
The first CD, "The House of Dispair" was written by Stuart Manning, who runs the
www.collinwood.net website (which is awesome btw), and if I remember correctly has been a fan for about 10 years or so? Feel free to correct me if I'm wrong there.
The next two, "The Book of Temptation" and "The Christmas Preseance" were written by Scott Handcock, who was introduced to the show by Stuart and became a fan before writing the scripts, or, to be more precise, he got into to get some background to writing the scripts and then perhaps became a fan? Hmm. I don't know.
The last CD, "The Rage Beneath" was written by Scott Alan Woodward. I don't know his story. Maybe if Stuart of Scott H. are lurking around here somewhere they can help clear up anything I may have gotten wrong.
