The Hardy Boys Casefiles #17
The Number File
Hot water in the Bermuda Triangle
Frank and Joe are soaking up the sun in Bermuda and doing a little sleuthing on the side. Their father wants them to check out a shady character named Bernhard Kruger, the suspected kingpin of a big credit card scam. But the brothers aren't making any headway--so far Kruger is clean.
When the Hardys spy on Kruger's villa, one of his thugs spots them. Before they know it, they're being tailed by a black sedan and run off the road into the ocean! This is not the act of an innocent man. Their vacation shot, Frank and Joe resolve to nail Kruger. But he's on to them, and he has other plans--like arranging for the brothers to vanish in the Bermuda Triangle.

About the author
Franklin W. Dixon
763 books997 followersFranklin 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.

The Hardy boys are in Bermuda to aid their father in a credit card fraud case. simple surveillance turns deadly and this time it's Frank who nearly dies multiple times. Also, they know who the criminal mastermind is, the problem is proving it.
Like most of the Casefiles books, there is plenty of action, adventure, and narrow escapes for both the Hardy brothers, especially Frank (though Joe also gets in scrapes) before the entire gang is caught with help from a semi-retired British Intelligence officer and his beautiful daughter. Fenton arrives at the end to take custody of the gang leader and his New York contact.
I enjoyed this one a lot - plenty of action made the story fast-moving and the setting, including various boats, was fantastic. Recommended.

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.

In this hardy boy's mystery the brothers are in Bermuda and are trying to enough proof of who the leader is of a credit card scam, how their system works, and just how many people are involved. They keep hitting a lot of dead ends, but they know they are close to uncovering the truth because they know that they are being followed as well as threatened.
This was the first book in the case files series that I read and I really enjoyed it! I thought it gave a slightly different spin with the story went and I look forward to reading more of these in the very near future.

When I was 10, all I would ever read were the Nancy Drew and Hardy Boys books I could find at the school library. Revisiting The Number File brought a wave of nostalgia, reminding me why I loved these stories so much.
Once again, Joe and Frank embark on a risky journey, and the thrill of following them through hell and back on this case was as gripping as ever.

This book was perdictable but had shades of the normal hardy boys survive death but pure luck or happenstance. Trying to hunt down a credit card stealing organization leads the hardy boys to Bermuda.
