Classic George Thompson City Mystery, meaning: lots of salacious prose and teasing nakedness, but the actual sex is all off stage; the rich bad guys pay for their crimes, while the poor often get off; innocent females have horrible experiences but mostly are rescued before being outright raped; and there are lots of females who're sexually avaricious. City Mysteries were something like the pulps -- the plots are over the top, the prose florid, the characters types rather than rounded individuals, and the appeal is not particularly literary, but rather the author's audaciousness and willingness to break rules, both literary and social.
