BURIED TREASURE was a reprint anthology of various Golden Age stories prepared by Greg Theakston for Caliber Press. A few issues had some Simon&Kirby reprints.
This story was from the Hillman book REAL CLUE CRIME COMICS v2#7, 1947, and claims to be based on a true story (in fact, it's "so amazing because it's true!"). I have my doubts.
The story features an island off the coast of Australia, where the natives had chased off a white garrison and threatened the mainland. In response, one man is sent in (with his wife and a doctor) to dominate the tribe, which he's able to do until things inevitably go wrong.
As I said, I doubt the truth of most of these "true story" comics, and this particular one is more unlikely than most (and perhaps a bit politically incorrect 50+ years early). It has some great S&K action from the era, and the black and white reproduction is sharp (though some of the greyscales are a bit dark).
