Patronus spellbook

"*Cupboard door opens as Lupin looks at it* What I want you to do is to go in there and bring back the spellbook containing the Patronus Charm."

- Lupin mentioning the book and what he wanted Harry to do.

The Patronus spellbook is a book with instructions and information on the Patronus Charm. Remus Lupin owned one, which he used during his Anti-Dementor lessons with Harry Potter. He placed the spellbook within a secret passageway accessed through the cupboard in Professor Cuthbert Binns's History of Magic classroom, and put a Boggart there also, knowing it would become a Dementor. Harry took the book with him and presumably gave it back to Lupin afterwards.
