If any of the Chinese workers do manage to escape, they will find themselves on an island, far from home, among people who do not speak their language, and who do not especially like them. The fact that Filipino workers will soon be arriving gives them a lot to think about. They will be up all night whispering to each other, trying to reconstruct their theories.
