Ah, I'm so pleased by the detail that not only might Grandmother Matilda have been a fairy, she might also have been rather wicked.

The little jolts of humor throughout are delightful - Segundus's possible reaction to cold iron, the conveniently disappearing mother-in-law, and so on.

And that little dig Segundus makes near the end about Childermass's employment with Norrell seems like exactly the sort of reaction he'd still have, even if he were trying to be more charitable.
