I took this as tongue-in-cheek when I first read it, but the idea has
really grown on me in the past few days.  It's not just the anagram.
(which has a precedent) It's the books.  Snape lives in a house lined
with bookshelves from floor to ceiling--like a library.

If Madame Pince really is Snape's mama hiding out at Hogwarts in
Dumbledore's witness protection program, maybe that's the reason Snape
came over to the good side (or a condition of Snape's coming over to
the good side).  Maybe that's why Dumbledore "trusts Severus Snape".
And maybe that wasn't really Madame Pince behind the long black veil. ;-)
