The structure of this mystery/thriller is very intriguing. Hannah is writing a novel about 4 strangers who meet in a reading room in the Boston Public Library, and then hear a scream from a woman is later found murdered. One of the characters is writing about these events, so this is a book about someone writing a book about the same mystery. Is one of the 4 the murderer? A delicious plot with a slow reveal of information – very impressive.
