The non-descript letter was delivered in spelled ink so as to avoid direct suspicion if opened by anyone else in the household. The ink will reveal itself in Bea's hand's only, though will remain visible to all after the fact.

Miss Alardice,
It is with regret that I inform you that I have been unable to find a solution to your predicament that I would feel right in recommending as your physician. I have cancelled our appointment for tomorrow, and do urge you to confess your situation to your parents.
With sympathy,
Dr. W. Pomfrey
