Solution

(iii) Dunstan was not a good character in the story. He was a liar, a blackmailer, a thief and really an unkind person. His family background was also described by the author which was the actual cause of such personality of Dunstan. His mother died when he was young and his father was not much of a father as he had kept all his sons at home in idleness. The narrator didn't clearly explain his passing away of him but surely he would die because of the evil actions that had taken him down.
