Casal,
This is Draco Malfoy, also known as your new Master. The Dark Lord is back, and he's planning a siege on Azkaban. Few will survive if he has his way. They're planning on rescuing you. You'll probably be required to Apparate away as soon as they give you a spare wand. Instead, this is what you will do.
You will pretend to leave, but actually go and find my father, Lucius Malfoy's cell. You'll open the cell, tell him of what is happening and then you'll create an opening for him to escape through. Then you'll transfigure him into an animal that can survive and escape the carnage. You choose what would be most appropriate. I don't care if it's a dung beetle, as long as he's guaranteed to survive.
Then you'll escape as planned, and you'll not breathe a word or a thought of this to anyone. I know you have no choice but to try and obey me, but here's a little added incentive: if you fail, I'll have you killed. Don't think I won't do it.
Give this letter back to the guard once you've read it over. He'll dispose of it. Don't expect to see him anymore either. He'll be taking a vacation shortly before the raid takes place.
Regards,
Draco Malfoy.
