About the author

Franklin W. Dixon

740 books992 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.

Perhaps some false advertisement on the title - there's little to do with vampires, but vampire bats do play a minor role.

A better title might have been "Danger in a Tent Trailer". It's quite astounding how much abuse the Hardy Boys' tent trailer takes in this novel.

But... since each chapter must end on a cliffhanger note, and since there are 20 chapters in this book, it's possibly easier for the author to end a chapter now and then with some damage to the trailer.

Some really bizarre characters - the Prince is realy strange, and Pick seems a bit weird too.

Worth a look if you enjoyed these as a youth and want to reminisce with an offbeat Hardy Boys tale that you missed the first time around. Or... if you're a young reader, this has got to be better than other YA Vampire books.

Hardy Boys with Chet and Biff and his dog too! I really liked reading this one to my boys after camping with my boys in the west of the United States. Great fun and a few GRE words to work through for my boys - which is always good. Not really expected with book number 50, like I expect it with earlier numbers. Favorite GRE word in this book was lugubrious. :)

The Hardy boys are chasing Whip Lasher, a practical joker. When Lasher leads them to vampire trail, the brothers have to get past the dangers that await them, but can they also get past Lasher too?
This is one of my favorite Hardy Boys so far because it involved one of my favorite animals, Bats!

It was a good short book to read.
There were a lot of times when I was reading and thinking to myself that they could have solved it earlier or easily, but the end was so good and unexpected!
Also I loved Biff, prince cuthbert and Fritz!

This one was a little all over the place and the lot meandered, and lost it's way from the original story, and yet, it was still enjoyable. The endless trouble that followed the boys and their friends on this cross country camping trip kept me engaged, even if the plot became somewhat.muddled.

First book I ever read of the Hardy Boys series, and I might say it was good enough to read the rest of the books, but, once I started reading the other books I found out that I had switched Frank and Joe around! The action was good, the mystery one that was quite interesting and they went out of Bayport. Compared to the other books in the series though, this one I remember quite a bit of, while others I can barely think of what was going on.

The Hardy Boys series is more for an audience that isn't looking for a deep read, but an enjoyable read that focuses more on the action instead of the knowing.

Frank and Joe bring along two of their friends on a camping trip in an effort to track down a gang who have been counterfeiting credit cards! Dixon will have readers cheering and gasping with every chapter in this entry!

So, like the trademark of the series, there are two mysteries going on simultaneously, however, this time the Hardy boys are chasing just one, and accidentally stumble upon the other.

The villainous characters got a little mixed up. There was just too much going on with very little explanation. Too many plot holes. The ending was very drab and trivial. Where did Fingers and his gang fit in? Till the end, Lasher was the main guy, and all of a sudden, he is working for an altogether different fella Pick. Pick is avenging Burn, but in the end he orders Burn around! So, what exactly was the chain of command? The ending didn't really make sense. Through the entire book, the story stretched on and on and on, with clues dropped here and there, and in one last chapter, it was all wrapped up (not neatly, if I must say). You realise that the characters you are reading about are actually inconsequential, and some new racketeers are running the whole show, characters introduced in the last chapter! So, needless to say, character development was also lacking.

The Hardy boys, Chet and Biff are camping and trying to solve two r is it three mysteries at once. There are jewel thieves and credit card counterfitters to find and put to justice. There are so many players involved it's hard to keep track and know who is part of what gang and who is on the up and up. Luckily they have Sherlock, Biff's bloodhound along as he can track people giving the boys a good start to finding the men they're after. They encounter a strange man who believes he is a Prince, descendant of royalty from King Arthur's time. They also befriend a rock climber, mountaineer man as they work to catch the bad guys and solve the mysteries that are piling up. They don't get much time to enjoy the camping experience in their tent trailer but they do get other kinds of excitement.

A good entry into the series, this one taking the boys out of Bayport and into Colorado. Chet is here to do the cooking and introduce the Hardys to a character that proves quite valuable later. Also in attendance is their pal, Biff, and his bloodhound, Sherlock. Biff gets his time to shine here as well.

There are two mysteries that accidentally cross into each other, with one of the criminal gangs trying to catch and get rid of the other. Not the usual cross-mystery subplot, so it made for a nice change.

My problem with the book is that Sherlock was treated more as a nuisance than as a valuable asset. He proved his worth at the end, but that was as much of an accident as anything else. Sorry folks, mistreat a dog, even a literary one, and you lose a star.

Recommended for fans of the series, YA mysteries, and young detective novels in general.

Find it. Buy it. Read it!

I found the book at an antique shop on the courthouse square in Goliad, TX last November. It once belonged to the Smithville Public Library, about two hours away in Bastrop County. The due date stamps range from April 18, 1978 to June 1, 2002.

It’s my 2nd Hardy Boys mystery I’ve ever read. It was copyrighted in 1971, but the writing and concept feel even older than that. The dialog and character actions seem downright absurd and unbelievable to me, but it is a dated youth/YA novel.

This was really good for Hardy Boys! Even though it's from the 70s and we have credit cards now, it felt like one of the classic older books. Nothing was too weird (except for Cuthbert, lol, who was lovable in a way) and the Hardys weren't too stupid. For once it didn't get dumb at the end!

HOWEVER. The author clearly does not know Western geography. East of Denver is NOT mountains, it's plains. Boring, wide-open, flat, very non mountainous plains.

They were really mailing it on this one. The boys were heading west with a camping trailer to investigate credit card fraud; but the boys didn't need to look for the baddies, the baddies kept coming to them.

The baddies were hidden in a forest, the only trail to the secret location was protected by imported vampire bats.

The Beat-a-thon continues, but not as bad as in the previous books. Only Joe gets taken out for the count, and then only once.. The KO Count is now up to 64!

This time the Hardy Boys and their friends are on a cross county camping trip to catch some crooks. Not so many kidnappings this time, except for the mass kidnapping and what was almost a mass execution at the end.

This is a well written series, very suitable for the era in which they were first published and still okay today for a boys adventure tale, though simplistic and, of course, crime-solving details are quite outdated.

Such a nostalgic read. Most of my friends had Nancy Drew, but the Hardy Boys was all I ever had. It wasnt astounding or anything but still a fun little book to get through quickly.

I feel like the early ones must have been better? This was verging on unreadable. Also, the Hardy Boys are cops.

An interesting story that is a bit more entertaining than some of the previous volumes.

The vampire bat angle has an interesting resolution to it.

Young people may find this an interesting read.

A decent adventure though one of many books that feel like it was named beforehand and the author didn't know what to do with it.

It was neat to read about the Hardy Boys coming to our state, but the plot was meh. Also, why is Chet always the one cooking and cleaning?
