What are the motifs in All About Love by Stephanie Laurens?

Status is a recurring idea in in the novel. Horatio's murder could be linked with Appleby's insecurity about his status. Appleby is born poor and never gets over the injustice of this. He is provided with an education that is good enough to allow him to become a secretary to a landowner, but he is born with a low enough status that he will never be rich by honest means. While in the infantry, Appleby considers the injustice of this. He has befriended a man who has been born with a little more. Appleby considers himself better, but is angry that he will never have as much. This is where his life of killing, stealing, and lying stem from.
