Tom Swift in Captivity

When he went to the caves of ice Tom had bad luck, for his airship was wrecked, and he endured many hardships in getting home with his companions, particularly as Andy Foger sought revenge on him.

But Tom pluckily overcame all obstacles and, later, he built a sky racer, in which he made the quickest trip on record. After that, with his electric rifle, he went after elephants in the interior of Africa and was successful in rescuing some missionaries from the terrible red pygmies.
