Dr. Pawson was the highly indvidualistic and idiosyncratic magic expert who discovered that Christopher Chant's weakness is the metal silver. He is completely unflappable and does not flinch when Christopher accidentally destroyrs his house. He has a doting old mother who is called Mrs. Pawson in the novel The Lives of Christopher Chant, and he has a patiently efficient servant called Mary-Ellen. All three of them play a distinctly important role in the development of Christopher's magic and character.
