Alan is the spy; Barry is the knave and Cole is the knight.
Explanation:
- None amongst Alan and Barry could be the knight because if they were, then they would be lying.
- In this situation, Cole has to be the knight and this also approves that Barry is not the knight.
- Now, someone is the spy and the knave among Alan and Barry, which implies either one or both of them are lying.
- As Alan declares that he is not the knight which we know is correct and hence, divulging him to be the spy and Barry, the knave.
