*a grey-and-white school owl comes bearing a message
Mr. Daemon Sadi,
Despite the recent, fortunate return of Sirius Black, his death only throws the precarious situation of this mansion into sharper relief. I would prefer to prevent any such deaths in the future, and I believe we may be the more successful with your help. At your convenience, I would like to meet with you to discuss the events surrounding Black's death, as well as possible strategies to contain similar threats. Merely send this owl back to me with any times at which you will available for a meeting, and I will also try to make myself available.

*the message sent, McGonagall also wouldn't mind running into Sam Spade; his post for Prewett on the bulletin board has been immensely helpful, but unfortunately, she's never met him before*
