When Arnold was fourteen, members of his immediate family (at least he and his mother) went on holiday with Uncle Frank and his two daughters, Sarah and Alice. Arnold was convinced that one or both of his cousins fancied him, so was very surprised when he awoke in the night to find Uncle Frank kissing him. Frank had entered the wrong room looking for Arnold's mother, with whom he was having an affair.
Arnold's brother Frank may have been named after their uncle.
Behind the scenesEdit
It is reasonable to assume that Uncle Frank was the brother of Arnold's father, otherwise he was having an affair with his own sister!
