Lily shook the thoughts out of her head. She was not supposed to be a part of this scheme. So there was no way that someone around her would be acting as a double agent.
Fourth were the Doomed Spies. These were the people who are openly declaring themselves as the enemy to deceive the other side. Some would openly act as a spy, while some would openly provoke the enemy or show the enemy some false plans and tactics. This person could be Pierre Weber as he was openly opposed to the Duke, and he was not actually trying to hide it.
Then the last one is the… Surviving Spies. This is the Spy that will bring back the information in the enemy's camp. They were quiet, and no one would think that they were involved in any spying. Some would see them as weak and cowardly and would laugh at them. These are people who are like bamboos… they bend and adjust to the strong wind. Then they would secretly deliver the information to the enemies.
