I'm aware of no business either for the Ministry or the Lord Protector that might require you to be absent from Hogwarts.

Moreover, it seems that several of your charges, including my son, have as a result of that absence ventured into danger.

You will return forthwith, Minerva. I am on my way and I sincerely hope you have a suitable explanation.

For your sake, Draco had better be less injured than that chit of a mudblood makes it seem.
