Can anyone recommend Victorian sensation novels? (See the Wiki entry at
https://en.wikipedia.org/wiki/Sensation_novel.) This was a common genre in the 1860s and 1870s. It was influenced by melodramatic novels; Newgate novels (novels about criminals); and the Gothic novel. William Harrison Ainsworth was one of the famous authors of Newgate novels.
I've read
Lady Audley's Secret by Mary Elizabeth Braddon, which is one of the most famous examples. I have some nice copies of Wilkie Collins books (even print copies!), and he's one of the other famous examples of Victorian sensation fiction authors. I'm also trying to read East Lynne by Ellen Wood (who published as Mrs. Henry Wood). But it's a long one!
There are a couple of Dickens novels considered to be sensation novels, but it might depend on who you ask. Some consider "Oliver Twist" to be a Newgate novel because it is about the lives of criminals.
