#austen sequel

Have any Austenites heard of this book?

I just discovered it at a local used bookstore. Published in 1914, it really is just what it says on the cover: it's more or less a continuation of Pride and Prejudice insofar as Elizabeth and Darcy are the main protagonists. But it interweaves characters, both major and minor, from Austen's 5 other novels as well; it's a bit like a who-knows-whom, which makes perfect sense since Bath is a common fixture in several novels, and I wonder why the BBC hasn't yet thought to either adapt this novel and/or create an original show with a similar set-up.
