From the introduction:
An Officer has abused his position to steal and sell important government secrets. The UIG, fearing their own investigators will arouse too much suspicion have conscripted a group of Agents to find the defector and bring him back; alive is possible, dead if necessary.
Their only clue is a transmission intercepted by the Archon Orpheus which points to a Mental Asylum in northern Russia.
Feigned Insanity is a blend of negotiation, interrogation and action in which Agents will work for the UIG and even travel in one of the Archon-built teleport stations.
