Dear Aunt Muriel,
Ron mentioned me recently that you’ve always wanted a House Elf. Since I have connections in that department at the Ministry, I thought I could help you out with your conundrum.
I have an elf looking for employment. Her name is Tuney, and she’s actually charmed not to ask questions, and never to talk about her past or her identity. I thought those qualities might interest you particularly. Ron also mentioned a coat cupboard underneath your staircase? I think it would make an excellent bedroom for her.
Please write and let me know. Since I am connected at the Ministry, please keep this offer a little bit quiet.
PS - thank you for your last card, by the way. The money was greatly appreciated.
