Quotes on Espionage

In civilizations without boats, dreams dry up, espionage takes the place of adventure and the police take the place of pirates.

Espionage, for the most part, involves finding a person who knows something or has something that you can induce them secretly to give to you. That almost always involves a betrayal of trust.

All warfare is based on deception. There is no place where espionage is not used. Offer the enemy bait to lure him.
