Several years ago, there was a murder mystery game show called Whodunnit? that ran for a season. It was entertaining to watch, but it was far too removed from actual detective fiction to provide much satisfaction as a mystery. As it turns out, two tie-in books written by show creator Anthony Zuiker were released at about the same time: Murder in Mystery Manor and Murder on Mystery Island. They are... pretty much the exact same as the TV show, down to format and flaws.
