The Motor Boys After a Fortune; or, The Hut on Snake Island

The three Motor Boys—Jerry, Ned and Bob—are always on the lookout for a new thrill, and this time a curious professor whispers of a hidden cache of radium on a lonely island deep in the Colorado River’s Grand Canyon. Fueled by the promise of a valuable and mysterious metal that can even set diamonds alight, they ready their motorboat for a daring trek into uncharted waters. Their enthusiasm is tempered by the professor’s warning that radium’s invisible rays can burn flesh and warp the mind, adding a palpable sense of danger to the hunt.

The journey quickly turns perilous when they discover that their trusted vessel has been seized by the unscrupulous Noddy Nixon, a rival who will stop at nothing to claim the prize for himself. As they navigate snaking river channels, strange “ghost” lights flicker over the canyon walls, hinting at hidden hazards they must decipher. With quick wits, teamwork, and a dash of daring, the boys race to reclaim their craft and reach the enigmatic Snake Island before the treasure slips away.
