Dear Rev. Lewis Bigler,
We have received intelligence that a Patronus Charm was used in your place of worship this morning at fifty-two minutes past ten. We would ask you to remember that any magical activity that risks notice by members of the non-magical community (Muggles) is a serious offense under section 13 of the International Confederation of Warlocks’ Statute of Secrecy. Further spellwork may lead to your incarceration in Azkaban Prison.
Yours sincerely,
Mafalda Hopkirk
