N or M? (Tommy & Tuppence #3), Agatha Christie
N or M? is a work of detective fiction by Agatha Christie first published in 1941. After the outbreak of the Second World War and many years after they worked for British intelligence, middle aged Tommy and Tuppence Beresford feel useless and sidelined. Then Tommy is approached by a secret agent named Grant to go undercover once more. Grant tries to find German spies and fifth columnists but is hampered by traitors within British intelligence who

A highly enjoyable spy thriller set during the outbreak of World War Two, the now middle-aged Tommy and Tuppence are soon thrust into action.

I much prefer Christie’s puzzle box mysteries, but there’s something about the Beresford’s that instantly appeal.
I like how they have aged to reflect the 1940’s setting.
My favourite of Christie’s thrillers.

To be honest, this book didn't feel so good at the very beginning. But, as the things went ahead, I kept on guessing. Even with obvious fact my belief dangled, and I couldn't be sure of the decisions I made about the antagonist. And by the end I truly loved this story. Its everything you want from a Christie story. There is misdirection, suspense and proper explanation of the facts.

Normally I try to be critical about mystery novels, but I have absolutely no complain about this one. So, a full ra
As light reading between more demanding literary works, Agatha Christie never fails. Although Tommy and Tuppence were always my least favourite sleuths of Agatha Christie’s, the detective formula largely follows the same formulas as in the Hercule Poirot and Miss Marple stories.

This one has a bit of Fawlty Towers about it. It’s on the eve of World War II, and T & T go sleuthing in a sleepy seaside boarding house. There they meet the usual suspects: a retired major, a strange foreign woman, a
***2018 Summer of Spies***

A fast, fun expedition into espionage! I liked the fact that Christie allowed her main characters to age and change a bit. As is true for most of us, they retained their basic characteristics which turned them into spy hunters to begin with, but they are dealing with details that afflict us all as we age. Younger folk (including the Beresford children) no longer see our relevance and no one wants the skills that we have on offer—just ask anyone who is over 40 and unem

This novel sees the detective duo of Tommy and Tuppence in the midst of World War-2. N and M are the initials given to two of Hitler's agents whom Tommy and Tuppence hunt for. A character in the novel Major Bletchley is a former Indian army officer who claims to know the secrets of Britain's wartime efforts. During World War-2, the code breakers at Bletchley Park in Buckinghamshire under Dilly Knox had broken German Enigma machine cyphers giving British military to Germany’s secret plans. Knox w ...more

This fantastic mystery kept me guessing till the very end. I never did figure out one of the suspects before the big reveal. The narrator, James Warwick, did a marvelous job, doing various voices and accents -- including a toddler's murmurings and another character's stammering -- which, I suppose, shouldn't come as a surprise since he's a television and movie actor (often working on Agatha Christie stories, by the way). The leads, Tommy and Tuppence, were funny, clever, and very entertaining. I ...more

That plot summary doesn't even bear a passing resemblance to this book. Whoever wrote it should be fired. Also, the cover of my edition is insane - I get the shoelace, the hammer and the note wound around the rock, but the vaguely racist imagine of a Native American in full headdress holding a shot gun? I can literally remember NO references to either of those.

The book itself wasn't Christie's worst, but it was far from her best. I mean, it wasn't a Passenger to Frankfurt/The Big Four level di

This was such a heartpounding, thrilling, World War 2, spy who-dun-it! I was constantly on the edge of my seat the whole time and read this in just over a day!
Probably not the best Tommy and Tuppence book to start with though, as I was, because they're imitating another personality and it's hard (at first) to determine which personality is actually theirs. But Tuppence is amazing. She's such a strong female heroine, and though To

Another excellent Christie read. First and foremost, this one reaffirmed my love for Tuppence; she really is a fantastic character. It's great that Christie has allowed us to see the progression of her and Tommy over time; the duo having grown from ambitious youngsters to middle-aged retirees with their own grown-up children. This in turn allowed for a great thread throughout this book about society being dismissive of people and their worth as they age.

The plot itself was as intricate and deftl
A rather, but amusing novel about Tommy and Tupence during wartime. While trying to find the spies, They have lots of adventures. Enjoyable book, a real cozy mystery.

Recommended to Anna by: T&T series
If I am remembering correctly, Tommy and Tuppence are the only major characters in Christie's works who age through their series ...

This story begins with a similar scene to the previous book, "Partners in Crime".
It's about 20 years later and the war is in full swing. With a nod to the opening of the previous book, Tommy and Tuppence are lamenting that they are not contributing to the effort -- except for Tuppence's knitting -- because they are considered too old for the action and even their fo

Really enjoyed this book by the prolific and entertaining Agatha Christie. This book N or M? is a fun ride even with it being set in 1940 England, WWII. The main characters are spies Tommy and Tuppence (husband and wife) sent to the coast to find and capture the male (N) and (M) female spies that were the leaders of the Fifth Column-German infiltrators-some sent years before the war, carefully placed to do the most damage when German invasion began. Many were politicians, police, military, intel ...more

The next installment in my quest to re-visit Dame Agatha's works: N or M? follows the adventures of Tommy and Tuppence during the war.

Full review posted at BookLikes:
Oh, Tommy and Tuppence I do love you two! And reading about your WWII adventures was just as fun and exciting as reading about your adventures during the 1920s.
Such fun! Spies, espionage, and patriotism! I loved Tommy and Tuppence and their relationship. I can't wait to read more about them!
As much as I love Tommy and Tuppence, the plot or mystery in this one was rather too easy to unravel. I figured out who the German Spy ensconced at the hotel was early on and was a bit disapointed it took Tommy and Tuppence so long to catch on. But it was still fun to go on another jaunt with T & T.
Where this book really shines for me is that it was published in 1940 and really gives the modern reader a little peak into the prejudices, thoughts and predictions about the war in its early day
All of Tommy and Tuppence mysteries are above all the rest; this one was, perhaps, a little more tragic, but with a pleasing ending-and the only thing that I really didn't like, was how their children were so uninterested in their parent's Great War stories, and thought they were past doing anything!

I really enjoyed this book which gives us Tommy and Tuppence in their 40's during WWII. Of course they want to help their country but it seems people of their age aren't needed. How they get involved with 5th columnist (spies working inside England) makes a quick, fun tale. It's unlikely the reader will figure out all of the twists and turns in this story, bu even when I remembered who did what and why I still thought the story held up well. Their kids are unnecessarily dismissive of our pair, b ...more

The author’s purpose in writing this book was to entertain readers. The author did this by writing a mystery. The author also provided information about the Fifth Column which was a group of German spies that had infiltrated all of Europe during WWII.
The theme of the story was that even middle-aged detectives can be as sharp as young detectives. The two protagonists had a hard time finding work during the war because they were considered too old to be of any use. However, they were brought in

Tommy & Tuppence are so witty and adorable; I love them. This book had me guessing the whole time, but I did suspect the right person for a while. (Then Agatha was too smart for me; I abandoned my suspicions!) It's set in 1940, with the middle-aged Beresfords frustrated at their country's lack of desire for their obviously invaluable help in winning WWII. (What could Churchill have been thinking!) The proposition to hunt out two top Fifth Column leaders from an assortment of seemingly-normal ...more

A Feb 2019 re-read confirms the review below.

Good old Tommy and Tuppence, up to their old undercover tricks to help prevent fifth-columnists sabotaging the British efforts in repealing an expected German invasion after Dunkirk. Well-written adventure mystery, with some interesting and humane thoughts about the nature of war and the demands it makes on protagonists on both sides. What a good writer Christie was!

I enjoyed this one, but not as much as I otherwise would have had I not guessed several plot twists... and then realized this was all vaguely familiar because I had, in fact, read this book before. I don't remember doing so, but halfway through the book I suddenly sat back with a deja vu feeling, and by the end I was definitely sure that I must have picked this one up at some point in my novel-filled past.

It's still a jolly good time when all is said and done, though. Honestly, who wouldn't want
This is a-m-a-z-i-n-g. I love how husband and wife work together to find a spy for the Germans during WW2. I will guarantee you probably won't guess who's the bad guy! One star off for some swearing.

We last saw Tommy and Tuppence in 1929’s Partners in Crime, which ended with the announcement that Tuppence was ready to enter their biggest adventure yet, having a baby. Now, in 1941’s N or M?, the duo faces a much more serious adventure than before in serving their country by seeking out a spy.

The Second World War is just beginning to gain momentum, and both Tommy and Tuppence keep getting turned down for any forms of war work in the basis that they are too old, though their twins have no trou
