When Stetson Jeff Stetson takes some time to think about a clue he picked up in Pennsylvania Dutch Country, he realizes that his hero, Ranger Johnstone, may have hidden some kind of precious cargo that he stole from the Russians in Havana somewhere in Belize. Precious... and potentially lethal. Could it be nukes? Of course it could. But what if the shadow organization A.S.P. beats him to it? Between encounters with sharks and agents from the counter-shadow organization R.A.T.S., will Jeff survive long enough to get out of sunken submarines and a cave with the bones of a male Mayan princess? Will he be able to jump the sharks? And who could possibly come to his aid when he's been betrayed? One thing is for sure, A.S.P. has raised the bar and threatens global security unless Stetson Jeff can beat them to the punch.

In the fourth book in the Stetson Jeff Adventures, the authors have taken a silly story and turned a corner. Jeff has become nothing less than a Modern American Tall Tale.
