This was written 2 weeks after Orion wrote to Sirius.
Dear Andromeda
Firstly, I know that Bellatrix and Mother and Father and Aunt Walburga and Uncle Orion will kill me if they know I am writing this to you, as you have been disinherited. Secondly, the subject of my letter is urgent. Sirius has been sorted into Gryffindor, and our entire family is furious. Please write to Sirius and tell him to apologise to his parents. He'll listen to you, even if he does not listen to me. Also, do not reply to this letter. Thank you, Andi. I'm sorry this letter is so short. I must go now. Lucius (you remember him, he's in my year at Hogwarts) is calling me.
Your sister, Cissy
PS:-Bella is getting married! Mother and Father are so excited. Her fiancé is Rodolphus Lestrange.
