Return Owl to Hermione
Dear Hermione,

Well, my offer still stands if you ever need a guide, but I'll admit that exploration can be much more fun.

I'm afraid that I don't really know much about time travel, though. I would suggest talking to Madam Pince about it. I think she probably knows every book there is in the library, and then some. I'm sorry that I can't be of any better help, I've just never really thought much about the subject.

Sincerely,
Alice
