, a double agent is an employee of a secret intelligence service for one country, whose primary purpose is to spy on a target organization of another country, but who is now spying on their own country's organization for the target organization. Double agentry may be practiced by spies of the target organization who infiltrate the controlling organization or may result from the ''turning'' (switching sides) of previously loyal agents of the controlling organization by the target. The threat of execution is the most common method of turning a captured agent (working for an intelligence service) into a double agent (working for a foreign intelligence service) or a double agent into a ''re-doubled agent''. It is unlike a defector, who is not considered an agent as agents are in place to function for an intelligence service and defectors are not, but some consider that defectors in place are agents until they have defected. Double agents are often used to transmit

Double agents

Re-doubled agent

A re-doubled agent is an agent who gets caught as a double agent and is forced to mislead the foreign intelligence service. F.M. Begoum describes the re-doubled agent as "one whose duplicity in doubling for another service has been detected by his original sponsor and who has been persuaded to reverse his affections again". * Vitaly Yurchenko

Triple agent

A triple agent is a spy who pretends to be a double agent for one side while they are truthfully a double agent for the other side. Unlike a re-doubled agent, who changes allegiance due to being compromised, a triple agent usually has always been loyal to their original side. It may also refer to a spy who works for three opposing sides, such that each side thinks the spy works for them alone. Notable triple agents include: *
