NEW CADET CHALLENGE

Congratulations to Cadet Shavon Lloyd who was the first (and so far only) cadet to correctly identify Harry as a knight and Dick as a Knave. 

Here's the latest cadet challenge.  This one is about a 6 on the difficulty scale; it's tough, but by no means impossible. 

It is Saturday afternoon. As you walk down the beach, you meet three residents: Tom, Dick and Harry. You know that none are Normals (see below). You ask Tom, "Are you a Knight or a Knave?" He answers, but you cannot make out what he said; so you ask Dick, "What did he say?" Dick responds, "Tom said that he is a Knave." At this point, Harry says, "Don't believe Dick, he is lying." What are Dick and Harry?  


Included below to assist you in your efforts are a list of possible solutions and a list of facts.  Read both carefully. 
Possible solutions

- Dick is a Knight.

- Dick is a Knave.

- Harry is a Knight.

- Harry is a Knave.

Fact list

- Knights always tell the truth.

- Knaves always lie.

- Neither of the men is a Normal.

- Dick says, "Tom said that he is a Knave."

- Harry says, "Don't believe Dick, he is lying."

This challenge will close 0730 Monday 23 January.  Be prepared to explain your answer.  This is a logic puzzler, no trick is involved.  Since this is a tougher than average challenge, there will be some tangible prize for the winner.  Good luck!
