I appreciate your desire for privacy. Do you wish to avoid St Mungo's involvement altogether, even to consult on her care, or is it rather that you wish to avoid your daughter's being admitted there?

If you wish, I could ask Professor Slughorn to send Miss Lestrange to me and keep her here when she is not sitting exams. That way she could remain in school until the usual end of term and avoid calling the attention to her circumstances an early departure would surely attract. Keeping her here would allow me to oversee her meals, if not treat the source of her condition.
