Considering all the answers, your answer seems right too. Thank you again!

Toogam, that's exactly what I'm trying to say. But mkennedy's answer seems right.

Barmar, you are quite right. I won't do it again. Sorry. Thank you for the warning.

Thank you. Could you give me an example, please? I couldn't find any horse racing expression like that.

Let me give you an example from the book that I really liked: "This putrid filth, molded into human shape, made only to fawn on the rich and beslaver them, thinking no foulness too foul if it were done in honor of those in power and authority; and no refined cruelty of contempt too cruel if it were contempt of the poor and humble and oppressed; it was to this obscene and ghastly throng that he was something to be pointed at."

Actually, the main character is hating the Victorian society. The author is merely showing the corruption of society here. I think according to the book, the people talking in this scene are evil.

There is nothing about a character named Lotty in the book. There is not much information about the old lord either. That is why I get confused. But I think you might be right. She must be the old lord's daughter or something. Thank you!
