20 September 1894,Dear Professor Lissington,My name is Hermia Bonnaccord. I was a student in your NEWT class that graduated in 1892. I have continued my education at Flint Institute. In my research, I have discovered a few things that makes me interested to reengage with the Patronus charm. It is my sincerest hope you would have time for a refresher on the subject.
Sincerely,
Miss Hermia Bonaccord
