Annie: Heathcliff, short, long hair, wears earring
Bernard: Sherlock, tall, long hair, wears earring
Carolyn: Romeo, medium, short hair, wears earring
Daniel: Harry, short, long hair, doesn’t wear earring
Since we know each person can be right about only 1 thing, we need to cross out similarities. Starting with Daniel, we know he has to be right about the character not wearing earrings, because he is the only student that had a different answer for that category, and the other 3 students can’t all be right about the same thing. This means we also know the character isn’t named Harry, isn’t short, and does not have long hair. Annie said he was short and has long hair and wears an earring, and we know from Daniel’s answers that those 3 things are incorrect. So, that means Annie is correct about the name, Heathcliff.

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
