Enclosed herein are the requested salve and what I could spare of my supply of healing potions. You should have enough of both to last you through Sunday, just in case, and I have already presented the illusion for my family that I am focusing on the review and further study of healing potions. If you should find yourself in need of more, simply send word and I will have more.
Although you are perfectly free to consider that you 'owe me one,' all I will ask in return, for the time being, is that you aid in preserving my secrecy. I have already removed things that could trace the potions, the salve, and their containers back to me; when you have finished with this letter, please kindly destroy it, and, should you find yourself in need of more potions or salve, please ask through a private ward on the journal. For these two measures, you will have continued access to my healing potions, as well as my heartfelt thanks.
Sincerely,
[Enclosed are the aforementioned potions and salve. The parchment is charmed to self-immolate ten minutes after the letter has been opened, if Fenrir hasn't already destroyed it by then.]
