Secrets from the Agatha Christie Archives

by Jared Cade

The untold story of how Agatha Christie conquered the serial market with her thrilling mysteries.

Dame Agatha Christie reigns supreme as the ‘Queen of Crime.’ Numerous books have been written about the legendary crime writer, focusing on nearly every aspect of her craft. But until now no one has carried out an in-depth investigation into how she conquered the serial market with her thrilling tales of murder and intrigue.

In the UK and US, Agatha Christie’s work was serialized in the most prestigious magazines and newspapers of the day, often under an array of different titles, prior to being published by Collins and Dodd, Mead and Company. Second serial rights could result in a single title being syndicated to over 40 newspapers. Over the decades, numerous records have been lost or destroyed and keeping track of her literary legacy has proved a major challenge for her publishers, literary agents and others until now.

Jared Cade, author of the ground-breaking biography Agatha Christie and the Eleven Missing Days, has unearthed a huge plethora of hitherto unknown facts about the timeline of her publishing history that will delight her devotees and enable future generations to write about her work with far greater authority and accuracy than ever before, especially when correlating her publications to the parallels in her life.

Illustrated with rare pictures, Secrets from the Agatha Christie Archives is destined to become an essential reference tool for fans, librarians, scholars, antiquarian booksellers, broadcasters and others interested in the making of one of the 20th century's most beloved writers.

Definitely one for the Agatha Christie fans as it is a discourse on each of the titles from date of publication, inspiration and transition to the screen.

Nearly fifty years after her death Agatha Christie remains the unrivalled 'Queen of Crime'. Her novels are as widely read today as when they were first published. New stage and screen adaptations continue to appear. Hercule Poirot and Jane Marple are as immortal as Sherlock Holmes.
The amount of research Jared Cade has put into this book is phenomenal. It is clearly a labour of love by a devoted fan.
The first 'adult' book I ever bought was 'The Moving Finger' - a bargain for sixpence in 'old' money in Tavistock market. I've since read all the novels and short stories but Jared Cade proves there is still so much more to discover and cherish in Dame Agatha's works.
This is an essential additional volume for Christie's legion of fans to savour.

Secrets from the Agatha Christie Archives by Jared Cade is the only book containing the most comprehensive biography and chronology of Christie's writing and her life ever written. Cade's meticulous research into original sources for serializations and publications really shines. Having all this invaluable information in one volume is priceless!

Agatha Christie is one of our most beloved authors, the Queen of Crime. As a teenager I was introduced to her books and was immediately smitten with her one-of-a-kind ingenuity, red herrings and characterization. I have read each of her mysteries multiple times as well as her Mary Westmacott stories. As a rabid fan, I have read books about her and books written in her manner by others (still seeking those which completely capture her). As Cade says, she earned and kept her readers' trust and always gave the same clues her sleuths and detectives were supplied with. No wonder her mysteries such as The Murder of Roger Akroyd remain the best-selling mysteries ever.

In this book, Cade explains in chronological order the reasoning behind different title names and covers of all her works (if known), publication and publishing history, the amount of money Christie earned, book stats, inspiration for titles (which book would have been The Man Who Grew Vegetable Marrows), serialization, trivia (such as a deleted scene and the beautiful story of a fan in a German labour camp), the widest book published, her mutual admiration of another treasured author P. G. Wodehouse, and forgotten works including articles written by Christie. This is quite the book!

This book is for you whether you are new to Agatha Christie or a lifelong fan.

My sincere thank you to Pen & Sword and NetGalley for providing me with an early digital copy of this entrancing and much-needed reference for those like me who need Agatha Christie as a constant in our lives.

This is a great treasure trove of purely archival information for anyone who is looking for the ultimate guide to Agatha Christie's works, published or otherwise.

Part One: The Classic Full-Length Masterpieces
This section goes through all the full-length novels in order of publication date, and there's so much info regarding newspaper serialisations of the novels around the world, various other printings (if available), plus some lesser-known trivia facts about certain titles.

Part Two: Masterpieces in Miniature
This section is set up the exact same way as the previous, but for all of Christie's official short stories and the short story collections that followed.

Part Three: Other Gilded Volumes
This section is in reference to other reprints of her works by various publishing houses, even up until quite recently. It features things such as omnibus writings, continuation cases, and a quotable Christie portion. For example, I did not know that in 2009 a volume of the complete Miss Marple cases was printed as a single book by HarperCollins in the UK and is now entered into the Guinness World Records as the world's widest book ever published. It weighs over 8 kilograms!

Part Four: Additional Jewels in the Crown
This sections is basically a catch-all for any other writings associated with Christie through her archive. Poetry, published and unpublished radio and stage plays, articles written by Christie herself, recipes, parodies and tributes by other writers including novels and other non-fiction works that feature Christie as her own character. I found this part of the book particularly fascinating since I was unfamiliar with many of the other works that revolve within the Agatha Christie universe.

Thank you to NetGalley, author Jared Cade, and Pen & Sword publishing for giving me access to a free digital eARC of this book to read. All opinions are my own and are provided here voluntarily.

Just when you thought you knew everything about Agatha Christie, boom! The new meticulously researched book, Secrets from the Agatha Christie Archives, arrives to prove you wrong.

Every published work of Agatha Christie, and a few rumored unpublished ones, are included in this comprehensive guide. Ordered by original publication date, each work includes a brief plot summary (with no spoilers), publisher, and even the selling price at the time. Both UK and US publications are included.

Some interesting tidbits are mentioned like why a book title was changed for US audiences and what was going on in Ms. Christie’s life at the time of publication. Another surprise was how often the novels were serialized in magazines and newspapers both before and after their hardcover release. The author states that Ms. Christie often made more profit on those releases than on the sales of the books themselves.

Secrets from the Agatha Christie Archives is definitely formatted like a research book. Reading it cover-to-cover like a novel is not recommended. However, reading each work’s section while also reading the referenced novel is great fun. It definitely improved the experience of rereading the less famous Christie books.

Secrets from the Agatha Christie Archives would make a great gift for the Christie fan in your life. 4 stars!

Thanks to NetGalley and White Owl for providing me with an advanced review copy.

Jared Cade's "Secrets from the Agatha Christie Archives" is an absolute joy for fans and scholars interested in Agatha Christie's writings and her publication history. Cade (who also wrote "Agatha Christie and the Eleven Missing Days") details every short story and novel that Christie wrote. He discusses the publication histories, the possible name changes, the money she received for the publications and other bits of trivia. Cade is so thorough and impressive in how much information he provides for every text. This is an immense achievement, I was in awe of how much research Cade has done in preparation for this bibliography of Christie's work.

I had no idea that many of Christie's novels were turned into comic strips. We also find out how her novels were often included in an omnibus. Cade includes so many of the original ads/promotional material for her works. This wealth of material is such a pleasure to read and examine for people who adore Agatha Christie. I decided to use the book as my inspiration for doing a complete reading/rereading of all of the work I can get my hands on. That's why this bibliography is a first-rate piece of scholarship because it gives a scholarly look at one of the best mystery writers. Cade makes the case for how integral Christie was to the mystery genre and to publishing as a whole. Wonderful book.

[Anne Morgan · Rating 3 out of 5]

This book is for the true Agatha Christie aficionado, those looking to understand the publishing order of her books, short stories, etc. A bibiography of all Christie's titles, Cade clearly did a lot of research into copyright titles and publishing dates for specific editions by different publishers to sort these out. Included are original prices and often reasons why the titles changed from UK and US editions and what Christie originally intended the titles to be. Occasionally there are bits of trivia, which I would have liked more of. Often you have straight lists of which magazines and newspapers carried the serialization of the stories. This became a little confusing when it got into reprints of short stories by Part 3 of the book.

Readers looking for a story line will want to skip this one, it really is a bibliography with a few tidbits of additional information added. But if you're interested in a complete bibliography of Christie's works and when they were printed in the US and UK, maybe for research purposes, this is a good source.

I received an ARC of this book from NetGalley in exchange for an honest review

Plongez vous dans l'univers d'Agatha Christie, soyez derrière la plume, et voyez l'histoire se construire sous vos yeux !

Pour ce livre, John Curran a eu accès à plus de 70 carnets de notes, dans lesquels Christie écrivait des idées, esquissait des intrigues, et expérimentait des rebondissements. L'ouvrage permet ainsi aux lecteurs d'explorer son processus créatif et de mieux comprendre comment l'autrice arrivait à
construire sous ses mains des chefs d'oeuvres de la littérature.

Ce bouquin contient également deux nouvelles inédites d'Agatha Christie, qui n'avaient jamais été publiées jusqu'à aujourd'hui.

Le Secret des archives d’Agatha Christie est donc un livre fascinant pour les fans de la romancière, car il dévoile l'envers du décor et le génie méthodique d'Agatha, en montrant notamment comment elle façonnait l'intrigue de ses nombreux récits.

Thank you netgalley and the publishers for providing an advance reader copy.This is my honest review.


For fans of mystery and crime, Secrets of Agatha Christie by Jared Cade is an incredible deep-dive into the life and mind of the legendary author. This book is primarily a fantastic resource for those interested in collecting, documenting or simply reading Agatha's works
Cade’s writing is easy to follow, which makes it suitable for anyone, whether you're new to Christie’s world or a long-time fan.

This biography ( more so a glossary of her works ) doesn’t just tell a story—it serves as a companion piece for appreciating Christie’s novels on a new level. Highly recommended for book clubs, academic study, or simply anyone wanting a fascinating read on one of the world’s most beloved mystery writers.

[Rich Portlock · Rating 3 out of 5]

While there’s nothing new in this book, it’s still a very useful book because the author has done a good job in trawling the net and the works of folk like Dr John Curran, Dr Julius Green and the Collecting Christie team.

Not sure about the “secrets” but this is a good book
