ANSWER

Matt is the mole. Both Alex and Nick are telling the truth.

When Alex said, ”Matt is a mole” he was telling the truth, and giving the correct answer.

When Matt said, ”Nick is a mole” he was lying, as he himself is a lying mole.

When Nick responded, ”Matt is lying” he was telling the truth and also affirming that Matt was lying.
