A scowl slowly grew on Severus' face as he read Draco's letter but when he reached the name and description he swore, loudly and with a great deal of creativity. He knew the man. A disgusting little healer by the name of Mortimer Thanatos who had a chip the size of a forest on his shoulder in regards to the Muggleborn. What the hell was Rodolphus planning? There were some very nasty theories coming to mind with the combination of an unknown spell being used at the ball and a vaccines being required.
Draco,
I know the man Miles met. He is an unpleasant Healer by the name of Mortimer Thanatos who despises the Muggleborn with passion that would make most Death Eaters look conservative. His involvement combined with the news of some kind of vaccine and what Miles did at the ball fills me with a great deal of dread. I have many theories, none of them good.
Lock down the manor as much as you can and given that I was at the ball, I think I shall stay away until we have more information on what has happened. I do not want to place any of you at risk.
