One agent alone will not do!
You are the brains of competing nongovernmental secret agencies in post-war times around 1950, steering your agents on the streets of Vienna. Your agents are looking for top-ranking whistle-blowers and their secret information on culture, administration, religion, nobility, and science.
In each round, you play cards that support your chase for secret information in one way or another. The player with the most points at the end of the game is the winner!
