Here ya go: The Sheriff of Nottingham had rounded up three suspects in the theft of a horse. (To the Sheriff’s dismay though, none of them were Robin Hood!) His informants from the local hamlet market all told him that each of his suspects was either a Knight, a Liar or a Knave, but the information conflicted and he couldn’t be certain just who was who, let alone who actually did it. He did know, however, that a Knight was honour-bound to always tell the truth, a Liar was, well, always a liar, and that Knaves always alternated between telling the truth and a lie. In order to sort this all out, he put the suspects (A, B and C) in the same room, and told them to each make, in turn, a total of 3 statements, from which the Sheriff hoped to deduce the truth. The suspects stated the following: A. B didn’t do it! B. I’m always truthful! C. A’s the Knave! A. I didn’t do it! B. A’s last statement was a lie! C. B’s last statement was a lie! A. C’s last statement was a lie! B. I didn’t do it! C. Well, I didn’t do it either! Hm-m-mm!! Who was which, and who did the Sheriff conclude actually did it, thereby saving the poor serfs of the Shire the expense of a long and completely unnecessary trial?
