The Watsons

The Watsons is an abandoned novel by Jane Austen, probably begun about 1803. There have been a number of arguments advanced as to why she did not complete it, and other authors have since attempted the task. A continuation by Austen's niece was published in 1850. The manuscript fragment itself was published in 1871. Further completions and adaptations of the story have continued to the present day. (This summary is from Wikipedia.)
