Not a certainty + no direct evidence from the pianist. So, I wouldn't rush to accuse Haven.

No, there's no other option here. Moreover, Haven is indeed Dungeon. Right now, there's no murder of bandits, and on the first night, a clue related to the murder of those bandits pointed towards him. This means the clue was deciphered correctly, and we were simply being overly cautious.
