Posting on the back off another thread. And it prompted me to post.
A fiction book about an old brother and sister, both bachelor and spinster. Sad lonely lives. They live by the sea. And I think the brother one strikes up a pen pal relationship with someone. Which bring happiness and joy and eventually love. Then the twist of the book at the end. Is that he finds out the pen pal is infact his sister!!!!
Can anyone help?
