It is known that one of A, B, and C is a Knight; the other is a Knave while the remaining one is a Liar. Nothing definite is known about the fourth inhabitant. A, B, and C, say:

A's statements:

1. The fourth person is a Knight like me.

2. Both B and C have been known to speak falsely.

3. C is less truthful than B or myself.

B's statements:

1. The fourth person is a Knave.

2. He (the fourth person) is not like me.
