> Hot on the trail of two million in diamonds, Doc is caught in jungle treachery by ruthless thugs, head-hunting natives -- and a lovely lady with cold-blooded murder on her mind.

The Bantam cover of this novel reuses a part of the artwork from the Bantam edition of "The Phantom City."

This one unfortunately is a disappointing end to the first omnibus. I know it's not right to judge a novel against the ones around it, but even on it's own this one is formulaic and dull. Basic plot, throw in some escapes, etc. Not a great Doc by any means. Too bad. Well, they can't all be great and the other three in the omnibus more than make up for this one's shortcomings. The first three are some of the best Doc you'll ever read.
