When the stranger of Goodnight Stranger lands on the island, he seems to know too much about the adult twins he befriends, so much that they wonder whether he could be their long-dead brother (why? no one really explains–and it bothered me). He insinuates himself into their lives, until the sister finally goes to seek the truth. In the process, we learn about their parents and family history. It’s all nicely mysterious and nicely told. Too bad I could never get into the delusion of the lost brother.
