Thanks to MSF for the following.
In the LOST Season Three DVD boxset, there is an insert for the LOST video game telling users to go to lostgame.com/dvd for a tip on the game. Well, that address does not work and results in a 404 error. However, if you go to lostgame.com, you get redirected to http://lostgame.us.ubi.com/. If you add on 'dvd' to that (http://lostgame.us.ubi.com/dvd), a screen pops up with a tip: Find the Turn of the Screw and Receive a Reward.
Here is a brief summary on 'The Turn of the Screw' by Henry James, courtesy wikipedia:
An unnamed narrator listens to a male friend reading a manuscript written by a former governess whom the latter claims to have known and who is now dead. The manuscript tells the story of how the young governess is hired by a man who has found himself responsible for his niece and nephew after the death of their parents. He lives in London and has no interest whatsoever in the children. The boy is at a boarding school whilst his sister, Flora, is living at the country home in Essex where she is cared for by the housekeeper, Mrs. Grose. He gives the governess full charge of the children and makes it clear he never wants to hear from her again regarding them. The governess travels to her new employer's house and begins her duties. Shortly thereafter, the boy, Miles, turns up after being expelled from his school. The governess infers that the headmaster feels that Miles is a threat to the other boys.
The governess begins to see and hear strange things. She learns that her predecessor, a Miss Jessel, and her lover Peter Quint (another former servant of the household), a clever but abusive man, died under curious circumstances. Gradually, she becomes convinced that the pair are somehow using the children to continue their relationship from beyond the grave. The governess takes action against the perceived threat, eventually culminating in the death of Miles.
So the next question is, what influence/parallels does this book have on LOST?
