Dear Professor Lupin
Firstly, I would like to express just how well of a job you are doing.
The method in which you teach your students is both inspiring and informative. I hope you received the card I sent you after you became ill when we were going to track down the werewolf that the students have been spreading rumors about. We of course did not find anything that would suggest the presence of a werewolf during that expedition, however, it was very fun.
Secondly, I would like to formally invite you to a weekly card game between myself and Professors Flitwick and Snape. I know we are rather late in asking you to join us, but quite honestly it only occurred to us last week, when we wanted to play a certain game but it required four players. In the end, Professor Flitwick had to charm the cards so they would play themselves, but I have the suspicion enchanted cards have a tendency to cheat.
Would you be interested? We meet every Thursday evening at seven (7:00PM) in the staff room. I do hope you will join us.
Thirdly, although I found no proof of a werewolf on the grounds, I have become increasingly worried that a werewolf may be in the castle itself. When I go inspecting at night I hear scrabbling, not odd in and of itself but as a inspector I have a variety of detection spells in my arsenal and when I cast them it told me that it is very likely a werewolf has been in this very school in the last month alone!
When I spoke to Professor Dumbledore about it he simply said that it wasn't his place to tell me about the private lives of those in this castle. You know sometimes he makes me wonder if he is part Goblin with how cryptic he likes to be.
You being a topnotch Defense Against the Dark Arts teacher I thought maybe you could help me with determining what this is all about. But I of course understand if you are too busy being a excellent teacher to help me with this particular problem. Which of course is quite alright, I am sure that Professor Snape would be willing to step in again to help if I asked him.
