A collaboration of giants!
So I just happened across this short story/novella by searching Elizabeth Gaskell on Project Gutenberg ... it's called "A House to Let" and it's a Dickens/Wilkie Collins/Gaskell/Anne Proctor collaboration. It was so good! Really a perfect combination of what each of them do very well. I'm now ISO other collaborations and writing from any of them about how their process worked.
Everyone should read it!
