      About This Book

      El Diablo—The Devil! The very name of the legendary outlaw strikes fear in the hearts of California ranch owner.

      Many years ago, the young El Diablo disappeared into a mountain cave, never to be seen again. But the ranchers think he may still be alive—especially now that an eerie moaning sound is coming from his old hideout.

      The Three Investigators set out in the dark of night to explore the moaning cave—and they soon wish that they were armed with more than a flashlight!
