I finally finished " The Partridge Family # 14 - Thirteen At Killer Gorge . " ( I had put it aside for a good long while . ( As you can see by the disparity of time between when I started the book until the day that I finally finished the book !! ) It was a good story , but the mystery was FAR too easy to solve !! ( I mean , even easier than in the rest of the books in the series !! ) There was really only one conclusion to make the whole time that I read the book !! The plot deals with a skyjacker ( Skyjacking was a major problem in those days !! ) that may have landed somewhere near Reuben Kincade's Aunt Polly's old boarding house ( Now empty !! ) Then , along comes this guy with a pretty unbelievable story about throwing his bicycle , complete with his money , ID , and other items at a snake . The bike and all of his possessions then went sailing off of a huge embankment !! The ladies of the Partridge Family are offered the chance to appear in a feature film . The catch ?? They will have to take Dulcimer lessons !! Each female Partridge in turn ends up leaving the movie . There is also the mystery of just why Reuben's Aunt Polly despises the gorge so much . All is revealed , cleared up , and finished by the end of the book , as always . There is one fairly dark moment in the end . The skyjacker meets his death at the hands of a Panther that has been prowling around throughout the story . I usually give the Partridge Family books five stars , and I thought about doing the same with this novel as well . But , due to the incredibly easy mystery , I could not . ( Sometimes , I admit tat nostalgia does play a part in my rating of these and other books from the era . But , that is a part of my enjoyment , so it is an honest rating regardless . If you are a fan of the Partridge Family , then by all means , you should read this book !! I have read all of the books in the series up to this one . I will be reading # 15 next . I can recommend these books for fun and light reading . ( Because that is precisely what they are !!
