ABSTRACT
Espionage is commonly defined as “that part of the total intelligence designed for the surreptitious inspection of the activities of foreign countries to ascertain their strength and movements and to communicate such intelligence to the proper authorities.” If only for security purposes, all nations feel the need to discover, by their own concealed methods, the guarded secrets of others. Or as Winston Churchill once wittily remarked: “Sometimes liberty requires a bodyguard of lies.”
