Sam Fisher- Casino Smoke

  I reach for the pocket on my right outer thigh and remove a smoke grenade, one of the more harmless ones. I carry a couple of different types of smoke grenades—one that only produces dark smoke to cover my tracks, and another one filled with CS, or what tongue-twister lovers call O-chlorobenzalmalononitrile gas. That stuff is nasty. Exposure to CS gas causes violent respiratory seizure, and prolonged contact produces unconsciousness. I pull the ring and toss the grenade behind me and wait for the loud pop. The thing works surprisingly fast. Black smoke fills the gaming room in less than five seconds. It’s almost as if someone simply turned off the lights. With my goggles on I’m spared the eye irritation and can also see the archway out of the room.

  I run into the casino’s main lobby and past a couple of frightened patrons. The entrance guards must have left their posts to chase me in the gaming room, because I’m home free.
