The ingenious plots of Agatha Christie's mysteries continue to intrigue readers decades after they were written. How did she do it? Drawing on her unpublished notebooks, personal papers and letters, this book offers a unique insight into the mind and working methods of one of the world's most popular authors. Among the gems in these pages are Christie's own essay on Hercule Poirot, a chapter deleted from The Mysterious Affair at Styles, and a previously unseen Miss Marple story.
