What are the motifs in The Line of Beauty by Alan Hollinghurst?

Henry James is actually a recurring idea. Nick is such a Henry James enthusiast that he is planning to attend graduate school to study the style of Henry James. He shares this information with Lord Kessler, who is genuinely interested. Lord Kessler retrieves his old family albums, which are kept under lock and key. He shows Nick pictures of Henry James at Hawkeswood, where Henry was once a houseguest. Nick is noticeably impressed. When with his friends, Nick quotes Henry James in general conversation. Nick does this as a source of entertainment for friends and acquaintances in social settings. He often considers what Henry James would do in certain situations, before taking action himself.
