Affiliate Marketing Secrets

So I am writing a story based in the Victorian era….I don’t want a lot of romance…I want it to be a dark comedy macabre genre….I know there were a lot of horrible things going on in the Victorian Era in England such as the black market, child prostitution, the occult, secret societies, freak shows and even incest and pedophilia….but I want my plot to tie in with one or all of those things….does anyone have any ideas?
