Clark says Bob is not a normal, which could be true, but someone has to be a Knight. If Bob was a normal, Clark would be lying which means he couldn’t be a Knight or a Knave. Since we know someone has to be a Knight, this means that Clark is a Normal, and Bob is a Knight. Bob is a guilty Knight, the
