Hi, I don't find out a copy of Permutations, DABA, so I use The Third Mind(1978) instead. Although I know the phrase needed for the shopkeeper in game, I'm not sure about its source. The short story "The Death of Mrs. D" of The Third Mind seems close to the original text or the written time 1970. If you can indicate the corresponding page number in The Third Mind, I would appreciate it.
