Your last correspondence has left more questions than answers. I would meet with you to discuss it. Midnight at Britain's most haunted home, if you would. I don't suppose that I need to say that you should come alone. I will want your word in writing on the subject. Again, notice the parchment being used.
Along with the owl is a set of parchment from Dumbledore's effects, charmed so that lies written on their pages will disappear.
