Camillo De Carlo, The Flying Spy
“ The most important part of our espionage system is conducted in our own territory, by sharpening our own spirit of observation, by seeking to gather everywhere all the many scattered rumors heard about the enemy. Details which at first may seem insignificant, may become extremely useful when compared with other details, collated with other observations and completed by detailed, careful investigations. The service of espionage is merely the application on a broad scale of a vast study of analysis and synthesis. ”
