Which book is being reviewed here by the editor of the London Sunday Express?

” … the most infamously obscene book in ancient or modern literature … All the secret sewers of vice are canalized in its flood of unimaginable thoughts, images and pornographic words. And its unclean lunacies are larded with appalling and revolting blasphemies directed against the Christian religion and against the name of Christ — blasphemies hitherto associated with the most degraded orgies of Satanism and the Black Mass.”

I’ll post the answer in a few days.
