How to think it through (Suppose and check): Suppose the first speaker is a truth-teller: their words are true. Work out what that says about the others. Check every statement. A truth-teller’s words must be true; a liar’s words must be false. If you hit a clash, switch the supposition. The possibility with no clash is the answer.
