In the subrule Doctor, set the text to

If a villager is the Doctor, e may secretly tell the mayor of a villager who is their target. If their target would otherwise have been killed by a werewolf attack, the doctor instead saves the villager from death. The Doctor may not target the same villager more than two nights in a row. If the doctor saves a villager, the mayor shall send a private message to the saved villager and doctor stating that the doctor saved the villager. The mayor shall also send a seperate message to all werewolves who were involved in the attack and state that the attacked happened, but was unsuccessful. Then the mayor may post a public notice stating the events of the night, that an attack happened and was foiled by the doctor.

Does this make Kevan the Mayor a ghost writer?
