Which Alice? Which Alice?
ALICE IN PUZZLE-LAND THEN WHO DID STEAL THE PEPPER? Suppose the Gryphon were guilty. Then he lied, which means the Mock Turtle is not innocent (like the Gryphon said) but is guilty, so we would have two guilty ones, which we don't have (as mentioned in the last problem). Therefore the Gryphon is innocent. So his statement is true, hence the Mock Turtle is innocent. Therefore the Mock Turtle's statement is true, so the Lobster is guilty. A METAPUZZLE For those who know the book, the Lobster (unlike the Gryphon and the Mock Turtle) never really appeared in Alice in Wonderland—rather he was a character in one of the poems recited by Alice. THE FOURTH TALE Suppose the Duchess stole the sugar. Then she lied, which means that what she said about the Cook not stealing the sugar was false—in other words the Cook must have also stolen the sugar. But we are given that only one person stole the sugar. So it is impossible that the Duchess stole it. Therefore the Cook stole the sugar. (Incidentally, both must have been lying.) THE FIFTH TALE If the Cheshire Cat ate the salt, then all three are lying, so this possibility is out. If Bill ate the salt, then all three are telling the truth, so this possibility is out. Therefore the Caterpillar must have eaten the salt (hence also the first two statements are lies and the third is the truth). THE SIXTH TALE If the Frog-Footman stole it, then he and the Knave both lied, so this is out. If the Fish-Footman stole it, then 142
