Making some assumptions, Beat began to simplify.
"Of drinks we have tea, faerie wine, poison, holy water, and presumably the potion we need or else this is a very cruel riddle. Don't look, I might do it," Erin admitted chipperly. "The ghost doesn't drink poison, because he does not live in the green house. He doesn't drink holy water because that is in the middle house. He doesn't drink faerie wine because he tells parables, not stories. He doesn't drink tea because the spirit drinks tea."
"Therefore!" Erin said, walking over and knocking on the first cask. "He has the potion, presumably."
"Now we just have to find the cat."
First Door: Ghost, Yellow House, Parables (Fox?) <--"It's more a matter of organization than intelligence, I feel," Erin said, examining Beat's notes, and on occasion murmuring corrections of her own, though these were directed towards Sergei. "The ghost is the the first house, and is next to the blue house, so the blue house is the second house by virtue of being the only one next door. The ghost can't live in the red house, because the saint lives there. He can't live in the ivory house, because that house in next to the green house. He likewise can't live in the green house for the same reason. He therefore lives in the yellow house. It says that parables are told there, so the ghost tells parables."
