About the author

Franklin W. Dixon

764 books997 followers
Franklin W. Dixon is the pen name used by a variety of different authors who were part of a team that wrote The Hardy Boys novels for the Stratemeyer Syndicate (now owned by Simon & Schuster). Dixon was also the writer attributed for the Ted Scott Flying Stories series, published by Grosset & Dunlap.
Canadian author Leslie McFarlane is believed to have written the first sixteen Hardy Boys books, but worked to a detailed plot and character outline for each story. The outlines are believed to have originated with Edward Stratemeyer, with later books outlined by his daughters Edna C. Squier and Harriet Stratemeyer Adams. Edward and Harriet also edited all books in the series through the mid-1960s. Other writers of the original books include MacFarlane's wife Amy, John Button, Andrew E. Svenson, and Adams herself; most of the outlines were done by Adams and Svenson. A number of other writers and editors were recruited to revise the outlines and update the texts in line with a more modern sensibility, starting in the late 1950s.
The principal author for the Ted Scott books was John W. Duffield.

What can I say about this book except that it was a total letdown. The charm of the Hardy Boys was replaced by a long tedious article. That is how this book is written. The only saving grace was The sci-fi convention description. Having never been to one it held my interest and the mechanics of the hovercar. Chet, the one person that might have added some much needed humor to the dry writing had his role cut to the bare minimum. Brian was too fake and how the accident happened was unbelievable. These boys are pros and yet one fell asleep only to find an elephant foot about to bash his head or falling down an elevator shaft... Like right in the middle of a discussion where everyone and everything is suspicious. I only read the book as I am a fan but to be honest the Hardy Boys lost its charm under certain writers. The premise was good but just not very believable.

My love of reading started when i was young, and it gives me immense pleasure to provide books to Spread the Word Nevada, an organization that passes them on to children in the community. They are a terrific organization supporting an important cause. If your local I encourage you to check them out. For those living further a field, look in your own community, their may already be a similar program in place. And if not, you can always help start one.

Myself, I go out on the weekends and
shop thrift store and bulk book lots to rescue books and donate them. Sometimes I'll find a book I remember reading when I was young and will read it again before passing it on.

I don't rate these books using my normal scale, instead I give most of them three stars. This isn't a Criticism of the book, simply my way of rating them as good for children.

When I first read Hardy Boys, I think I was in class 5, I had such a crush on Frank Hardy. I liked the brainy one over the brawny one and that sums up my first impression of Hardy Boys.
In their late teens, Frank and Joe Hardy take after their detective father Fenton Hardy. Frank is the older of the two and has more breakthroughs in the cases because he is the brainy one. Joe is the younger brother who more often than not is useful when things get hot and they need to fight their way out.
Like Nancy Drew, the books in the The Hardy Boys series re written by ghostwriters under the collective pseudonym Franklin W. Dixon. And yes, the earlier books were better than the latter ones.

This book's setting is mainly in Bayport's BayCon (science fiction convention).

The genre is realistic fiction.

I think that you should read this if you are a fan of mystery and like a real page turner. You really cannot predict what will happen next, like when the arrow comes out of the movie screen.
