- "He's a spy, Captain. He's THE spy. His secrets have secrets."

A secret agent, or spy, is a Sneaky McSneakerson who is always up in your stuff. Spies may be employed by the governing body of a country who uses them to ferret out sensitive information about threats to the country or to its people. Since people generally don't like it when someone is all up in their bidness, being a spy tends to be a fairly dangerous vocation. To make their jobs easier, spies will often employ a variety of fake identities, weaponry and an ongoing assortment of cool gadgets and gizmos.
