Need recommendation for historical novel for research

Hi, I'm looking for some recommendation from you guys favorite third person historical novels. I need to do some research from the 18th or 19th century. I'd love a few that includes mystery. I'm writing a short story with a blend of historical, mystery and paranormal.

 

Novels about the 18th/19th century, or novels written in the 18th/19th century?

 

Novels about the 18 or 19 century, please.

 

Here's a link that might be a great deal of help. You can choose your 'period' and a few other things as well. I'm not sure, but I think most of these are contemporary novels, written about historical periods ...which seems to be what you're looking for. Good luck!
