I adore Michel Faber's 'Crimson Petal and the White' : sumptuously dark poetic detail and wry wit. He paints Victorian London like no-one else.
I'm looking for recommendations in this historical genre, with the plot focus on sexuality/double-standards: intelligently written.
I read 'Gentlemen's Club' recently - by Emmanuelle de Maupassant - and also enjoyed that (more explicit than Faber but a similar feel to the writing).
I'm finding it difficult to locate other works of the same quality (rather than 'romantic fluff').
