First Edition. Charles Pont dustjacket art. Rare novel dealing with the U. S. Border Patrol listed in Hubin as a marginal mystery. Set on the Mexico-California border in the country of Calexico and Mexicali, the Border Patrol squares off against an American fruit grove owner whose "multi-colored hordes of workers" keep his production costs down. "Out every night to break up the smuggling, the Patrol have never landed the wily leader of the gang, one Tranquilino McCoy, an Irish Mexican who repeatedly slips through their fingers". Near Fine in Very Good dustjacket, shallow loss at lower spine end, modest soiling to panels, rubbed at top spine end and some edges.
