Harper has that most unenviable of jobs — Private Secretary to John Smith in the Ministry of Defence. A denizen of the Corridors of Power, he has access to (and visibility of) his Minister at even the most delicate and indeed inappropriate of times. Educated at a very expensive private school, Harper is steeped in the arts of diplomacy and tact, subtlety is his byword, discretion his badge of honour. What private thoughts and plans he has he keeps strictly to himself. Well, almost.
