My spy hero is Bernard Sampson from the Len Deighton Trilogies - starting with Berlin Game, Mexico Set, London Match. He talks about how experienced spies are like frightened old women and avoid risks and it's only the noobs who charge into things bravely. Sampson is the believable opposite of Bond who would obviously not have a long life in reality. Sampson is still extremely brave - just not idiotic - and he's very clever but human so it takes time for him to work out what's going on.
