Arthur O. Friel 
Pathless Trail 

After graduating from Yale, Arthur Friel served as a South American correspondent for the Associated Press. Once established in the region, he spent much of his spare time exploring, including a six-month-long river expedition in Venezuela. His travels provided ample fodder for the dozens of action-adventure novels he would pen over the course of his career, including the thrilling Amazon jungle tale The Pathless Trail.
