Consider the story of a deep-cover operative inserted into a transnational drug cartel or a terrorist sleeper cell. The first six months are the most dangerous. This is the "Proving Ground." The subjects of the investigation will test the agent constantly. They will ask about fabricated family histories. They will drive past a "safe house" to see if the agent looks back.
