I don’t quite know how to begin this, I know you are grieving, but father had something important to discuss with me when I visited him in Azkaban. I need you to find a book and send it to me, please. It is in the Manor library, near the celestial bodies section in a glass case. Father said blood is required to open the case. Inside is a tome, Sanctissimus. It is old– likely worn. Please send it as soon as possible, it is urgent. I would explain more if I could.
