This was a really interesting book within a book.
The "outer book" is that of an author writing to an American, getting help on making sure that her book reads like it was written by a native of the United States. While initial letters are helpful, later letters prove to be less than.
The book our author is writing is that of four strangers meeting in the Boston Public Library. Initially, they all sit at the same table. When a scream rings through the library, everyone is asked to remain where they are and the four begin talking to each other. That one experience brings them together again and again. Well, it's the scream coupled with the fact that a woman is found underneath a table in another room of the library.
The characters are well-developed and we even get to see some of the development through the letters exchanged. The mystery is also well-developed though it got a little over-involved for my taste.
Overall a well-designed book that keeps readers engaged and enjoying the story.
