Notes
The series title, "Sky Detectives" is most appropriate, for every modern boy is extremely interested in aviation. Our author has chosen Jack Ralston and his pal "Perk" famous air pilots to help "Uncle Sam" unravel baffling problems of the Secret Service. The adventures of these two detective aviators form the complete series, although each book is a complete story in itself.
