I am a huge Agatha Christie fan and am particularly fascinated by her eleven day disappearance in December 1926. I mean, who isn't, right?! The Christie Affair by Nina de Gramont is an interesting take on what happened during those mysterious eleven days. The novel is told from the perspective of Nan O'Dea who is the mistress of Archie Christie, Agatha's husband. Events unfold along the eleven day timeline, but also flash back to different points in time from Nan's past as well as Agatha's. The book also contains an unexpected murder mystery that was rather interesting.

On the whole I feel like this subject is a huge undertaking and my judgment may be clouded by the fact that I read and loved The Mystery of Mrs. Christie by Marie Benedict last year, but I had a hard time really getting into this storyline. The timeline jumps were abrupt and difficult to follow whose story I was reading. It would often take me several sentences before I knew what time and perspective was being conveyed. I also found the connections between Nan O'Dea, the murder mystery, and the rationale and goings on with Agatha Christie's disappearance to be convoluted and reaching. I"m sorry to say I didn't find this as compelling as I had hoped. Thank you to St. Martin's Press for the ARC via NetGalley in exchange for my honest review.

It may just be me, but I did not like Nan O’dea for many reasons. As narrator for Agatha Christie’s life and disappearance, Nan comes off whiny, pompous, and arrogant.

I’m a big fan of Agatha Christie and don’t like the light this painted her in.

Though this story wasn’t one of my favorites, I do recommend you read it for yourself because you may enjoy it.

This is an imagining of then cause and what happened during Ms.Christie’s disappearance.


Nan is a compelling narrator at first but the interjection of her past and her voice becomes grating.The writing style loses steam and had me flipping through the last half of the book.


This isn’t a bad book but it isn’t memorable.

This is a fascinating story. Told mostly from the prospective of Nan O'Dea, the woman who had an affair with Agatha Chrsitie's husband and who eventually becomes his wife.

Throughout the story you realize that Nan planned and plotted the whole relationship. It's the why that really reaches out and grabs you.

This story has so many interesting layers, including the relationship between Nan and Agatha that develops during the time Agatha goes missing.

Not usually the kind of story I like, but I am so glad I took a chance. Very entertaining read!

Thank you Net Galley for allowing me to read an advance copy of this book!

The Christie Affair by Nina de Gramont is an extremely gripping story. I had no idea what to expect and even though I was 75% through the author still had me guessing. I certainly did not see that turn coming. The tale has twists and turns and keeps the reader anxiously reading until the last word.

I will give all of you a caveat. Agatha Christie is not the main character. The story is told from another woman’s perspective. The main part of the story takes place during an eleven day stretch during 1926. I will not divulge any of the story here but suffice it to say it was well done. The characters were expertly crafted. The setting was so well written that you could smell the sea air. I would wager to say that Christie fans would love to read this side of the coin. It is also a wonderful read for readers of historical fiction.

This may be my first book by Nina de Gramont but it certainly will not be my last. While I catch up on what I have missed, I anxiously await her next book.

I would like to thank St. Martin’s Press, Nina de Gramont and NetGalley for the ARC in exchange for an honest review

For someone who loves mysteries, as I do, I have never read an Agatha Christie book and have no inclination. However, I do like to read books about authors, especially historical fiction. The author recreates the missing days of Christie in a creative manner. By narrating from the mistress’s perspective, readers will gain a different insight. It was an imaginable read and very interesting.

I adore Agatha Christie and historical fiction so I couldn't wait to read this one! It's a wonderful imagining of what may have happened during Ms. Christie's mysterious 11 day disappearance back in 1925. I always loved that the greatest mystery writer of all time managed to create her own mystery, which continues to intrigue and baffle all of her fans to this day.
Very enjoyable read!

A wonderful we-written dive into the life of Agathie Christie. However, the narrator is the mistress of Agatha's husband, Archie. I was utterly enthralled by the story and felt like I learned a lot of intimate details about the mistress of suspense. Superb!

This book was an intriguing reimagining of the days Agatha Christie disappeared in 1926. It is told from the viewpoint of Nan O'Dea - the Other Woman - who was Archie Christie's mistress and second wife.

As the story develops, we learn about Nan's past and her reasons for pursuing Archie. Along the way there is romance and murder and revenge for a great wrong. The murders were not center stage and seemed to be almost a throw away detail in the bigger picture when they were first described. I liked the echoes to some of Agatha's stories - very MURDER ON THE ORIENT EXPRESS.

The story was not fast paced but unfolded in a leisurely manner that still managed to be intensely gripping. Revelation after revelation build a strong picture of Nan and, peripherally, Agatha Christie and Archie Christie who doesn't fare well in this story.

The story also illuminates the time period between the first and second world wars when mores are changing and there is more than a social revolution going on. Nan's history includes horrific details about the fates of unwed mothers and their babies during that time period and in that place. Agatha's own growth, as depicted in this story, is also an example of social change.

This story was an interesting imagining of those missing days in Agatha's life told by a woman who is just a footnote in Agatha's story but a strong main character here.

At times this book was intriguing, creative and interesting but the constant changing of narrator and points-of-view within a chapter was quite annoying and distracting. While the author has provided a well-written narrative, I thought the Agatha Christie part of the story, the mystery of her disappearance, took a back seat to the life and secrets of Nan O'Dea, Archie Christie's mistress.

Despite some short-comings, I did enjoy reading The Christie Affair and am glad that I took the time to read this book. Thanks for St. Martin's Press and NetGalley for the opportunity to read this advance copy.

An entertaining fictional exploration of Agatha Christie's 11 day disappearance in December 1926, although it doesn't really seek to try to explain said disappearance. I enjoyed how the novel contained a tiny murder mystery, much like an actual Christie novel. While Nan O'Dea, the narrator, is fictional, she is an interesting character. And while the disappearance of Christie is the linchpin around which the novel is centered, it is really the story of Nan, and what it means to love and lose.

"'A long time ago, in another country, I nearly killed a woman. It's a particular feeling, the urge to murder. First comes rage, larger than any you've ever imagined. It takes over your body so completely, it's like a divine force, grabbing hold of your will, your limbs, your psyche. It conveys a strength you never knew you possessed. Your hands, harmless until now, rise up to squeeze another person's life away. There's a joy to it. In retrospect, it's frightening, but I daresay in the moment it feels sweet. The way justice feels sweet.'

So begins The Christie Affair, told from the point of view of Miss Nan O'Dea, a fictional character but based on someone real. In 1925, she infiltrated the wealthy, rarified world of author Agatha Christie and her husband, Archie. A world of London townhomes, country houses, shooting parties, and tennis matches. Nan O'Dea became Archie's mistress, luring him away from his devoted wife. In every way, she became a part of their world--first, both Christies. Then, just Archie.

The question is, why?

And what did it have to do with the mysterious eleven days that Agatha Christie went missing?

The answer takes you back time, to Ireland, to a young girl in love, to a time before The Great War. To a star-crossed couple who were destined to be together--until war and pandemic and shameful secrets tore them apart.

What makes a woman desperate enough to destroy another woman's marriage?
What makes someone vengeful enough to hatch a plot years in the making?
What drives someone to murder?"

Thanks to NetGalley for the free ARC in exchange for my honest review.

As a lifelong Agatha Christie fan, I was so excited to read anything that includes her. I found this book to be very interesting - I had no idea that Christie's husband Archie was in an affair. The story is captivating, and the plot twists were somewhat predictable, but still satisfying.

Trigger warnings: war, suicide, rape, infants taken away from mothers

"A long time ago, in another country, I nearly killed a woman."

Nina de Gramont's novel begins with this sentence that sucks the reader in and takes off running. Although the sentence is true, the story unfolding is not at all what the reader would expect.

Nan O'Dea is Archie Christie's mistress and is biding her time until Archie divorces Agatha. Mrs. Christie is not a household name yet but has a few mystery novels published. When she disappears after Archie tells her that he's leaving her, the entire country is captivated by the story of her disappearance.

Was the disappearance an elaborate publicity stunt? Christie's next novel would be published the following January. She becomes a household name and is still known as Agatha Christie despite her divorce from Mr. Christie.

The story that unfolds is told by Nan and is mostly her story, but she shares what she's gleaned from Agatha and Archie. The narrative switches back and forth between Nan's childhood in pre-WWI Ireland and the time her life intertwined with Archie and Agatha.

Nan O'Dea is a fictional character but is based on a real woman. Through her narrative, the reader finds a desperate woman who will do anything to get what she wants -- which surprisingly isn't Archie Christie.

The reimagining of what happened during Agatha Christie's disappearance -- and why -- is a plot worthy of one of Christie's novels. I enjoyed this version of the story more than The Mystery of Mrs. Christie by Marie Benedict.

Highly recommended for fans of women's historical fiction and Agatha Christie.

A 5-star premise with a 3-star plot

“Authors created problems, they didn’t solve them.”

The Christie Affair is a mystery centered around the sensational and scandalous chain of events that led to Agatha Christie’s disappearance for 11 days in 1926. Told through the eyes of Agatha Christies’ husband’s mistress, a story of secrets, revenge, and lust emerges, resulting in a startling murder.

The day after Agatha's husband Archie Christie tells her he is divorcing Agatha and leaving her for his mistress, Agatha Christie disappeared without a trace for 11 days. Her car was found abandoned by the side of the road with her possessions left inside. Thought to be dead, a nationwide search was launched to find the missing mystery writer. What happened to AC during this time is imagined by Nan O’Dea, Archie’s mistress, and the woman who caused it all.

Told from Nan’s point of view, I didn’t enjoy the narrative style. Relying on her imagination, Nan tells the reader what happened to AC. She rationalizes by speaking to the reader and explaining why this is ok. She paints an almost cartoonish picture of Agatha Christie, who comes across as an eccentric, borderline obsessive, and hysterical woman with no regard for her child or others in her life.

I love the idea of this book. What happened to AC and why she left is a compelling storyline. However, this book focuses on Nan and her rationale for stealing Archie away from Agatha. Nan’s story is both interesting and horrifying; however, the two storylines don’t meld. The two parts are competing against one another.

There are a lot of unanswered questions and plot holes. Pieces come together in the end and paint a picture of how the events connect in an AC-style mystery. However, to get there, one has to overlook many coincidences and unexplained events. The Christie Affair is an ambitious undertaking with potential, but it left me wanting more.

I received an ARC of this book from NetGalley and the publisher in exchange for an honest review.

I have yet to actually read any Agatha Christie books but the premise of this caught my attention. I read some reviews that were bothered by Nan’s version of the story when she wasn’t even there. But I actually enjoyed the unreliable narration. A few plot holes and one character I didn’t care for. But overall an entertaining read!

While this book is interesting and well written, it's just not for me.
I read and read and just didn't enjoy it at all. I do not like leaving poor reviews and won't if at all possible. I wanted to love this one. I honestly did. But that being said, I found it to be a tad boring. I was never into the Agatha Christie books or anything Agatha. That is obviously just me from the reviews I have read.

I'm truly sorry.
Thank you #NetGalley for this ARC. This is truly how I feel.
3/5 stars and that is because I did finish but still didn't enjoy it at all. I recommend you read it for yourself. You may love it,

This was an interesting premise. I have always loved the disappearance of Agatha and wondered what really happened. I thought that this was a very interesting idea of what happened, but I do wish it would have been Agatha's story and not her husband's mistress telling it. The overall story had some great mystery to it, which made it a compelling read.

I absolutely loved this book - the author creates a whole story about what may have happened during the 11 day disappearance of Agatha Christie in 1926, after her husband told her he had fallen in love with a younger woman.

Interestingly, the point of view is from her husband's mistress. She describes her life as a child, spending summers in Ireland and falling in love with a boy there. I wondered at first, how this had anything to do with the plot of the book, but later felt that Nan O'Day's life was more interesting and compelling than Agatha Christie's disappearance.
I won't go into any spoilers, but the way Nina de Gramont ties events in Miss O'Day's past with Mrs. Christie's present is very enjoyable, similar to an Agatha Christie murder mystery novel.
It is a heartbreaking visit to the past and a place in the present where things can be imagined into being as one wishes them to be. Highly recommended!

Agatha Christie as a fictional character is having a moment, as are books that speculate on what happened during the author's 1926 disappearance, and The Christie Affair stands out. This story fictionalizes the woman Christie's husband was having an affair with as Nan O'Dea, and in a remarkable feat makes Nan the story's most interesting and complex character. Nan's reasons and her backstory are heartbreaking and fascinating, and readers might be surprised at how much they sympathize with "the other woman" by the end of this story.

For starters, I love anything to do with Agatha Christie and this premise was so intriguing.
The story was very compelling. The idea to have the POV from the mistress was a unique twist on narrating the story. I think it worked for the most part but could get a little confusing until I got used to the writing style.
I went into this thinking it was going to be mostly about Agatha but it’s not really. As the reader, we learn more about Nan and what lead her to be entangled into Agatha’s life.
I would definitely recommend this book to any Christie fan. I think it will also appeal to readers who enjoy mystery and historical fiction.
