Interesting. I looked up Clarence Rook and found he is known for the "Hooligan Nights" series.
This article debates the likelihood that it was Victorian slum reportage, rather than Victorian fiction, but the author insisted it was rooted in fact. I think it seems like a mix of the two.
I'm guessing something this old may be available at Project Gutenberg or something like it.
