Ah, the good old days when sexual sin incorporated "adulterer, sodomite, lesbian and rapist" all in one category. The book was written in the 1980s but has a much more old fashioned feel to it - and not in a good way. With its combination of a slow moving plot, a not particularly appealing detective who, it seems, is meant to be an ordinary bloke but at times comes across as merely vulgar, and the heavy-handed treatment of its "deviancy" theme, it wasn't one for me!
