Who's the thief? A theft was committed by one of the 9 people (called One to Nine) but the police don't know who did it. Here are their answers when questioned: One: Five is the thief. Two: No, it's not true! Three: I did it. Four: Either Three or Eight is the thief. Five: Two said the wrong thing! - Six: Three is the thief. - Seven: No, Three is not the thief. Eight: I'm not the thief, and Three is not, either. – Nine: What Eight says is correct, but Five is not the thief, either. If only 3 out of 9 statements are true, who could be the thief?
