Hugo also discovers he has a long lost sister, Thomas gains a Rolls Royce, and Jeremy is sent on a life changing and life threatening journey, into the depths of the Congo. The reward at the end of his journey is threatened by outsiders who intend getting hold of the valuable diary, which has been passed down to him.
