Michael Wolf, a member of the stellar Morris-Jumel Mansion docent crew, alerted me recently to a potentially significant episode in the pre-Revolutionary history of the house. I say "potentially significant," because there may be a fly in the ointment: it is not yet clear whether the episode took place in the real world or only in someone's imagination.
