double agents

Spies serving two

A double agent is a spy who pretends to work for one side while actually serving another—or who has been discovered and turned to work against their original employer.

The term implies active deception rather than mere switching of loyalties: The CIA suspected their informant was a double agent feeding them disinformation.

Extended to any context involving betrayal through false allegiance.
