As he did in the Edgar®-nominated and Agatha, Anthony, and Macavity Awards–winning Agatha Christie's Secret Notebooks, Christie expert and archivist John Curran once again examines the unpublished notebooks of the world's bestselling author to explore the techniques she used to surprise and entertain generations of readers.

Drawing on Christie's personal papers and letters, he reveals how more than twenty of her novels, as well as stage scripts, short stories, and some more personal items, evolved. Here are wonderful gems, including Christie's essay on her famous detective, Hercule Poirot, written for a British national newspaper in the 1930s; a previously unseen version of a "Miss Marple" short story; and a courtroom chapter from her first novel, The Mysterious Affair at Styles, which was edited out of the published version in 1920; plus an insightful, well-reasoned analysis of her final unfinished novel, based on the author's notes and Curran's own deep knowledge of Christie and her work.

A must-read for every Christie aficionado, Agatha Christie: Murder in the Making is a fascinating look into the mind and craft of one of the world's most prolific and beloved authors.
