To escape, he jumps into the ocean but injures his ankle in the fall. In the caves, Jason subdues the hermit who tells them his story: he was a prisoner on Malo with Jason's father, Adam, where the two devised a plan for one to escape and return to rescue the other. The hermit was the one to escape but fearing for his life having killed a guard during the escape, he never returned. Encouraged to learn his father may still be alive, Jason return with the others to the ship where he informs his mother they are making plans to go to Malo to rescue his father. Aaron's truancy has his schoolmaster, Mr Quilter, upset. He brings his concerns to Mrs Quinn but Aaron cannot be found Ñ he has stowed away on the raft taking the boys to Malo. Arriving at Malo, the boys make camp for the night. In the morning, Jason is gone... setting off by himself to search for his father. He soon returns but Mark has already gone in search of him. Jason returns with good news, he's seen a list of prisoner's names, a list that includes his father's. The boys set off to search for Mark.
