Buster Crabbe #7 (1952)

Buster Crabbe and his sidekick Whiskers race into the heart of Jivaro territory to stop a doomed expedition led by the deceitful John Brown, who may be the outlaw Henry Madden in disguise. As they follow clues through the jungle, they encounter wary tribesmen, hidden dangers, and a growing sense that time is running out—before the next move is made, it could be too late.

In the dusty frontier town of Buster Crabbe, retired detective Calvin Carlson—still very much alive despite being 107 and a billionaire—entertains his bodyguard Jo with tales of his own murder, which he solved posthumously. When a mysterious riddle tied to his will is revealed, only the true murderer can answer it, setting off a tense showdown where the solution hinges on a single, unexpected word.

When Gold Rush Gus sets up camp, his clumsy attempts to pitch a tent lead to a comical tangle with his partner Lightning, who’s quick to mock his lack of frontier know-how. Amid the chaos, a sudden burst of excitement comes from a promotional flyer touting a "Miracle Skin Doll" with magical hair that curls, waves, combs, and washes—right as Gus’s antics take center stage.
