Alan, Barry and Carl (each either a Knight or a Liar) were rounded up by the cops yesterday, because one of them was suspected of having stolen money from the bank. The three brothers made the following statements under very intensive questioning:

Alan: I'm innocent.

Barry: I'm innocent.

Carl: Barry is the guilty one.

If only one of these men is a Knight, who stole the money?

Since Barry contradicts Carl,one is a knight and one is a liar.
In either case,Alan is lying and guilty.
By the way,Barry is a knight.
