I’m partial to Wilkie Collins, so I’m used to turgid prose. :)
I like Wilkie Collins, too. I have “The Moonstone,” “The Woman in White,” and a collection of his ghost stories.
With writers of this era, it might take the first hundred pages of a novel to adjust to the style. If you give it that, you can enjoy a great story.
For really long works - Anna Karenina, War and Peace - I get recorded books and listen to them in the kitchen while cooking or washing up.
