What saves Huck from being accused by the king and the duke of stealing money?

The dauphin nearly strangles Huck out of anger at his desertion, but the duke stops him. The con men explain that they escaped after the gold was found. The duke and the dauphin each believe that the other hid the gold in the coffin to retrieve it later, without the other knowing. They nearly come to blows but eventually make up and go to sleep.
