The first section of this book is a bio of Christie's life that includes a lot of info I'd never heard before and does go into the infamous 11 day disappearance. The rest of the book is sectioned into places that either factored in Christie's personal life, such as her homes or the church where she worshiped, while many locations are places she placed her characters, such as doing their shopping in certain stores or staying in a London hotel. Each section also has a listing at the end with which of her novels addressed in that chapter, so, if you wanted to hunt for the Brown's of At Bertram's Hotel, it's easy. ( )
