The Stetson Jeff Adventures Vol 2

The second paperback volume of the Stetson Jeff Adventures includes three books: Book 4, Danger in Dangriga; Book 5, Combat on El Camino; and Book 6, Denouement in Dallas.
Our hero Stetson Jeff Stetson has found his way home, but a copy of a letter sent by his hero Jeremiah P. Johnstone sticks in his craw. What was Johnstone doing in Cuba during the missile crisis, and more importantly, what did Johnstone do with what they found aboard a Russian sub? Follow Jeff as he pursues the shadowy organization known only as A.S.P. to the reefs and jungles of Belize, and on to Iberia. Stetson Jeff even spends part of a semester at Oxford University in pursuit of an honorary degree. But will Stetson Jeff be able to save the world, or at least, the most important part of the world: Dallas Cowboys Stadium? And what's going to happen with his sweetheart Daisy May Cook?
