Watching Roger Moore on ITV4, I'm puzzled as to what the Saint actually does. Is he a spy? A policeman? Or does he just drive around in a sports coupe waiting for conspiracies to happen?
In the books (on which the tv is based), ST is a gentleman thief/burgular, robbing and ruining and occasionally killing "bad" people and returning the funds to the wronged people less 10% for himself. Basically Robin Hood taking a percentage.
