Wee spoilers for Snuff and Feet of Clay
I'm super-excited about this one, because I've actually written a YA novel (unpublished) about a tosher in an alternate Victorian London, so it will be fascinating to see what Mr Pratchett has done with similar material. I'm just a massive Victoriana geek in general, and particularly when it comes to Victorian London, and particularly
particularly when it comes to the various underground worlds of Victorian London. If anyone's interested in some background reading, I can recommend a couple of really fascinating non-fiction books on the subject.
As for scatalogical content...well, it's going to be pretty unavoidable given the subject matter, yes? I did notice a lot more scatalogical references in Snuff than in previous books, but I saw that as deliberate, particularly in terms of characters like Young Sam, Felicity Beedle and Harry King, who see something worthwhile or interesting in things other people consider to be disgusting waste, with the obvious parallels to the goblins.
Terry Pratchett has always thought poo is funny - he's English
In Feet of Clay, for example, there's a memorable scene with a whole city full of panicked animals doing...what comes naturally to panicked animals. Not to mention Colon's trip down the "river". And sexual content is nothing new either - the entire concept of the Seamstress's Guild is one long nudge-nudge wink-wink.
IMO, one of Mr Pratchett's many charms as a writer is that he appeals on so many different levels, from the incredibly clever and nuanced to shouting "Underpants!" and running away.
