Remus Lupin was used to strange stuff. But this was entirely weird. He stared down at the piece of parchment, wondering if the wolf in him had finally succeeded to in turning him mad. ~~~
Remus gets a mysterious note on a piece of parchment which he can't stop thinking about. It doesn't help that his best friend, Sirius, seems to know who has written it. Picture from cemreilgaz (tumblr).
