An Alfred Hitchcock and the Three Investigators Mystery. Book 26 in the series.
If you've never read any of these, they are, in my opinion, the *best* of the young adult mysteries. Beginning in 1964 and the last in 1987. Regular stories, find-your-fate went to 1990.
These stories really incorporated all that we love from from cartoons like Scooby-Doo and movies like The Goonies and detective work inspired from the Hardy Boys.
Stories of haunted castles, treasure maps, hidden treasures galore, mummies, ghosts and more.

In The Mystery of the Headless Horse, the boys make friends with a Mexican American boy, Diego Alvaro, and his older brother Pico, at their school. Their ancestors were the first land holders in California and their history goes back to Cortés.
Over the years, their many thousands of acres of land has been whittled down to one last ranch.
But now their greedy neighbor, and father of the Three Investigators' arch nemesis "Skinny" Norris, is set on getting their last piece of land - by any means necessary!
The Alvaro's only hope is to find a priceless family heirloom, a Jewel encrusted sword, a present from the King of Spain to Cortés and then from Cortez to the Alvaro ancestors.
This relic would bring enough money to save their land. But it's been lost since 1846! Can the Three Investigators find it?
Adventures in historical societies and libraries pouring over old dusty maps, diaries, and documents, discovering intriguing stories and finding more questions than answers. But always finding more clues!
An excellent mystery, one quite deserving of the Three Investigators!
