Spoiler: Deirdre McCoy
A bit disappointed at first, Deirdre nevertheless perseveres and says, "Um, hi. I'm Deirdre McCoy, part of the little club Professor Jones presides over. The Society. He should know what I'm talking about. Anyway, yes, could you leave this message for us? We are trying to get into contact with Mr. Knott. Just, if he could give us a phone number to reach him, or an address, that would be great. We're at the Parker House Hotel in Boston, and he can just leave a message for us with that information too, if he misses us. Got it?"
