How it works

Every witness is either honest or a liar. An honest witness only says true things, and a liar only says false ones, like the knights and knaves in Raymond Smullyan's puzzles. Each of them makes one statement below. Your job is to mark every witness honest or liar so that all the statements hold up together. Exactly one way of doing that works, and you can reach it by reasoning alone: try a guess, follow what it forces, and drop it the moment two statements clash.

The statements

1. The StokerThe Tanner is a liar.
2. The JewellerThe Butler and the Stoker are the same kind.
3. The ButlerThe Stoker is a liar.
4. The MasonThe Stoker is honest.
5. The TannerThe Butler and the Mason are the same kind.
