Why I Reread This Book: I was lucky enough to find a hardcover edition a few weeks back and decided to reread it as a comfort when I and my wife were sick.

The Three Investigators was easily my favorite detective series as a kid, and two or three of the books had a huge impact on me. I don't think I read The Mystery of the Moaning Cave until I started collecting the books a few years back.

The series was created, and set up, by Robert Arthur. I'd thought he wrote the first ten in the series, but t...more

Fans of The Lost Boys will recognize the city of Santa Carla in this 1968 young adult thriller by William Arden. For readers who know California, Santa Carla is roughly Santa Cruz with a little bit of Santa Clara thrown in.

In The Mystery of the Moaning Cave, the three investigators decide to solve the mystery behind a recently moaning cave rumored to be the resting place of El Diablo, a Zorro-like figure. The cave sits on the property of the Crooked-Y Ranch.

The three investigators use a number...more

This is the very first 3I book I ever read. After 37 years, it's still a firm favourite. The boys go to the Crooked Y ranch, where the cave in Devil's Mountain has started to moan again after 50 years. They come upon a diamond mine, eccentric old prospectors and a 19th century Mexican bandit. This was the first of several books for the series penned by William Arden, but he emulated the original author's style so well that few readers noticed the difference. A very good story.

An old cave, rumoured to be the resting place of a famed bandit called El Diablo, has suddenly begun to moan and no-one knows why. There by accident - Pete’s dad knows the ranch owners - the boys decide to investigate and came up against legends of the Old One, a scar-faced mystery man, two old prospectors and a gripping mystery. The first non-Arthur book (he gets the credit, William Arden wrote it), this is well-written, clever and full of atmosphere - well worth a read.

Reviewing this series for my older boy, since it was one of my favorites when I was his age. It's striking how much freedom these boys took for granted at 12-13 (I've never been able to decide how old they really are; all I know for sure is that in none of them are they old enough to drive or care that much about girls).

The first book of the series not written by Robert Arthur, it's a decent mystery and story with some downsides.

The boys are suddenly scuba diving and horse riding experts? This really bothered me, especially the scuba diving part. In the books by Robert Arthur the boys were much more believable as average adolescents who were great at solving mysteries. The whole thing with the navy was another unnecessary, unbelievable part of the story.

The mystery itself was pretty decent and while parts of i...more

I don't know why these books never "made it" bigger than they did. I sure enjoyed them as a child. The mysteries seemed...reachable somehow to me. Like they were something that if I had been part of the team, I could have contributed to solving them. And yet they weren't boringly predictable (at least at my then younger age). I'm considering collecting these now as an adult in hopes that my kids may become interested in them. -And I guess because I'm sentimentally geeky that way about the books...more

I think this one might have been the first of this series that I read. It was soon after my "Western" phase, and the Mexican outlaw had enough western flavor to interest me at the time. After that I was hooked on the Three Investigators and quickly devoured all of the series that the local library had. I read mysteries for a while after that.
Scott
This is the first of the series with a different author and you can tell. Just not as good as the previous books, not as exciting, plot not as well developed, characters just a little bit flat.
I enjoyed it but wouldn't recommend it unless you either have excess time or already own the book.
Janice
I loved these as a kid and still own them.loved the era and a lot of connections to movies.
I have original hardback editions, 1-22, missing book 3 I think. I'd love to find a hardcover of this.

It turns out it was haunted by bootlegging vicars from San Luis Obispo. No, really.

I think this is still my favorite of all the 3 investigator series
