Im trying to find a spy game that I can't really remember that well but I want to play again. I believe it was a free game that you could download. It was very short. The game started at a party and you had to read a card, I think, and put some sort of bug in a drink and poison someone. After a while in the game you had to chase another spy by going through a tunnel and over air ducts (I think that's what they were) and after a while she shoots you and you fall to your death.
I'm not sure most of this information is correct but this is what I remember.
