Spy vs. Spy pre-RPG

[ProfessorLizzard]

Do you know "Spy vs spy"? (if don't here is wikipedia link about it: en.wikipedia.org/wiki/Spy_vs._spy) If yes, and you like it, then we should make a "Spy vs spy" RPG! Sadly I don't have much ideas about how to adapt it into an RPG. Can you help me?

My ideas so far:

• A Spy Master who controls the game.
  
• Some Spies would have to do mission, and other's should try to prevent it being done.
  

I would like to hear your ideas.

BTW here's my agency idea:

B.A.S.A (B. Ákos Special Agency) or P.A.S.H.A. (Prof. Ákos Special Hiding Agency)
Leader: Prof. Ákos
Sub-leaders: Cyrill, Cyrill's Moose, Small Sister
Uniform: Brown Coat and Baseball Cap, Black Sunglasses, Gloves and Boots
Speciality: Gadgets, Pscyhology
Government: None.
Cause: Good, and everithing else.
