About the author

Stephen Ronson

4 books69 followers
Stephen Ronson grew up in Sussex, and spent a large part of his childhood exploring the woods and fields around Uckfield, many of which were still dotted with reminders of WW2 - pill boxes, tank traps, nissen huts, and graffiti left by soldiers awaiting D-Day.

He is a passionate student of local history, and when he learnt about Auxiliary Units - groups of men who were instructed to lay low during the predicted nazi invasion and lead the fight back, he knew he had to write about a Sussex farmer, one with a love of the land, and a natural desire and ability to get the job done.

Many of the locations and characters in the John Cook series are inspired by real places and real people. In particular, Stephen was inspired by his grandparents, Eric, Bessie, Peter and Vera, each of whom did their bit on the home front.

1940’s Sussex Farmer, John Cook, is back for book 3 in the series, and what a pleasure it was to reconnect with him. Although he hates the city, Cook decides to leave his beloved Sussex countryside for a short time, and take his evacuee, Frankie, to visit his family in London for his birthday. On the face of it, not a good idea, as he has watched wave after wave of nightly Nazi bombers passing over his farm on their way to London.

In 1940’s Britain, there was food rationing, blackouts and air raids. Germany began conducting mass air attacks against British cities, beginning with London, in an attempt to draw the RAF Fighter Command into a battle of annihilation, which would allow Hitler’s forces to invade Britain. First World War veteran Cook has been tasked with preparing the resistance effort, should the worst happen. This then is the backdrop for this gripping WW2 historical thriller.

Whilst in London, attempting to just stay alive, Cook is made aware of Ruby, Frankie’s sister, who has gone missing shortly after leaving her job at a Lyon’s teashop. Cook being Cook, can’t help but become involved, but it turns out to be a much more dangerous situation than he thought, because there’s another problem too, is she part of a network of spies?

Cook’s friend, Lady Margaret, is a gift to the German High Command, but is she now a traitor to Great Britain, or will she prove herself to be just the opposite, or in fact, has she a hidden agenda?

Author, Stephen Ronson, transports the reader right back to 1940 and the blitz in London, to feel the tension and fear that comes with a city that is being reduced to rubble, particularly in areas around the docks, where Frankie’s family lived.
Well written and well researched ‘The Blitz Secret’ grips from the start, and with secrets galore and spies in the shadows, it’s difficult to know who to trust.

The bravery and heroism of the population shines through too, and none more so than John Cook. War and its ensuing pain, misery, and hardship, makes one wonder at the fortitude and perseverance required both to live, and to survive it, when every night could be your last. This story brings us a glimpse of what they endured, along with the crooks, gangs and spies that lived among them. Definitely Recommended!

First and foremost, I did not realize that this was the third installment of a series when I requested it. Uuuggghhh!!! I am one of those readers who is very fussy about starting a series from the beginning and this story was a classic example of why I am like that – I was definitely at a loss as to what was going on and who the cast of characters were. This book would NOT make for a good standalone, and I highly recommend reading the first two installments first, which I will definitely do at some point.

Even after reading the book summaries of the first two books, I was still a little confused, from the get-go, about the cryptic references to previous events and individuals, and just assumed that the story most likely started after some cliffhanger in the previous installment. Farmer John Cook is heading into London with Frankie, a kid he is fostering. Frankie was evacuated from London, along with a lot of other kids, out to families in the country to keep them safe from the bombing attacks in London.

There is another storyline of Margaret, who is a British spy as well as Cook’s lover. Margaret has infiltrated a band of German spies but realizes pretty quick that she needs to escape and get back to London before they kill her. There is also another storyline of Ruby, Frankie’s older sister, who survived a bus bombing only to be abducted by a creep who became obsessed with her when she worked as a waitress at a local restaurant.

The story flips back and forth between Cook’s and Margaret’s storylines. Cook starts to come into London regularly to look for Ruby, as a favor to Gracie, Frankie and Ruby’s mother. Margaret is being pressured to complete her mission, even though she has grave concerns for her safety and keeping her cover. By the second half, Cooks storyline of looking for Ruby dominates and it’s a frantic search to find her. The end comes in a gruesome and shocking end. However, I believe the final scene was a lead-in to more of Cook and Margaret to come.

The character development of Cook, Margaret and a couple of other primary characters, especially Reynolds, was well done. The pacing steady to fast and the storyline was interesting once I got passed the initial confusion; the same can be said for the writing too. I haven’t decided if I’ll continue with the series or go back and read the first two installments. Maybe. I’m looking at an overall rating of 3.9 that I will be rounding up to a 4star review. I want to thank NetGalley and Hodder and Stoughton for sending me this eARC in exchange for my honest review.

'The Blitz Secret' is the third instalment in the John Cook series and things feel somewhat different this time around. John finds himself in London, not exactly his favourite place in the world. And Lady Margaret is ... well, somewhere else. On a mission. This marks the first time the "team" has been split up and, to be honest, it felt off to me from the very beginning.

John is taking Frankie, an evacuee he's been looking after, to London to see his family. But boy, did he choose a really, really bad time to go to the city. Hitler is angry and London is bearing the brunt of it. Bombs are flying all over the place and nowhere is safe. Not even in some of the shelters, as it turns out. The "keep calm and carry on" attitude is incredibly weird, but also wonderful to observe. Sure, parts of London may be burning but people are still going to work, or to the pub, and some are still committing crimes.

A young girl has gone missing during an air raid. It is assumed she died when a bus was hit by enemy fire. Even if it means having to stay in the city longer than he planned, John would quite like to find out what happened to this girl. Obviously in his case that means getting on the wrong side of people. War or no war, crime pays and what happens in the dark alleys stays in the dark alleys.

Meanwhile Margaret is there, and then somewhere else. A prisoner there, a prisoner of sorts here. I found it rather confusing and wasn't quite sure as to what it was she was doing exactly. Her chapters felt somewhat distracting and drew away the focus of the story, which in my mind was the missing girl. That being said, she still kicks serious behinds, and fronts, and woe to anyone who underestimates her.

It all seemed slightly chaotic, the going back and forth, the switching between Margaret's work and John's search. It felt like there was a lot of running around from here to there, and back again. I never really became invested in the goings-on or the characters, and I would have preferred staying in London as that is where the excitement was. I didn't feel Margaret's chapters brought much to the storyline, apart from a Meanie McMean moment at the end which was quintessential Margaret.

For the most part, I think I just missed John's life in Uxbridge and his work with the resistance, his wee community doing their bit for the war effort. Somehow I feel that's where he shines the most, with Margaret by his side. Splitting them up didn't strike the right chord with me, even though initially the idea of them being off doing different things seemed rather exciting. The spy angle is definitely something that intrigues me, and the question of which side Margaret is on will keep anyone guessing. Including John.

'The Blitz Secret" might not be my favourite book in this series but it is still well-written, well-plotted and very descriptive. Even though some things didn't quite work for me, I did enjoy it and I look forward to finding out what's next in store for John and Margaret.

John Cook returns for the third installment in this WWII historical adventure series. Cook decides to take Frankie, his ward/evacuee from London, into London to see his family for his birthday. Bombing raids are occurring sporadically at night in London so he plans to make it a quick trip and return to the relative obscurity of the countryside. While there, Cook becomes aware of a missing young woman named Ruby. Ultimately, he decides to try to find Ruby and determine whether she is alive or dead. His investigations in London among spies, gang thugs and prostitutes expose him to deadly danger.

From the quiet and darkness of the Sussex countryside to the spy-ridden menace of wartime London, this third novel in the series brings all the usual vivid depictions and meticulous research of Ronson’s two prior novels. Bombing raids are reducing swathes of the city to rubble, anyone could be a spy and therefore untrustworthy, and the ARP (Air Raid Precautions) are protecting the homefront with varying degrees of success. Against this adrenaline-filled backdrop, John Cook launches his own investigation into a missing girl case. To anyone familiar with Ronson’s first two novels, it is not surprising that the novel is well-written and filled with careful details. It is action-packed and full of adventure, although I must admit to being somewhat confused at times, with the abundance of characters and secret agendas. That isn’t a fatal flaw however and the confusion could just be mine. A solid addition to an exciting series.

A great surprise! I didn't know what to expect, and this was really good! I realised this novel is part of a series but one can read it as a standalone without any problems. I loved the plot enjoying the fact that I couldn't guess anything. A good writing style has enabled me to smell, see and experience London during the blitz. I loved Cook and his calm, Margaret and her courage as well as the people of Wapping, the island. The conclusion was brilliant, intriguing and now I can't wait for the next book! Highly recommended!
I received a digital copy of this novel from NetGalley and I have voluntarily written an honest review.

5 ⭐️⭐️⭐️⭐️⭐️ review of #TheBlitzSecret by @stephenronsonauthor which is out now.

This is book three in the Farmer John Cook series, and having loved the previous two ( The Last Line & The Berlin Agent ) I had great expectations for The Blitz Secret, and i was not to be disappointed!

We are transported to London 1940 when Hitlers Blitz began with avengence and let me tell you,I actually felt like I had been taken back in time! Stephen Ronsons talent at writing a novel set during WW2 is just amazing, it is so atmospheric and immersive!

Cook and Frankie the evacuated boy, return to London to visit his Sister for his Birthday after being away from home for many months,and what transpires begins an enthralling and gripping tale of murder, kidnap, assault and in the underbelly of the London Docklands where hard working but poor Londoners do what they must to make ends meet.

With a surprise return of Lady Margaret which again is just sublimely written, we see how London was full of spy's and where trusting people could be at your peril.

The Scenes that Stephen has written during bombings and air raids were like watching a film,they are SO realistic! The attention to detail to historical fact is wonderful, and put together with a gripping thriller of a story means The Blitz Secret is an unputdownable page turner!

Stephen Ronson is one of the best historical authors specialising in the wartime period, and this book is the best yet, I dare anyone NOT to be immersed in wartime reading it! I love this series as I love John Cook, a fiesty, brute of a man whose heart is ultimately in the right place but who will use his skills from the last war to fight those in the wrong, to great effect!

Superb novel for fans of WW2 Thrillers, if you haven't read the previous two books, I urge you too as read in order there is a backstory to John and Margaret!

Huge 5 ⭐️⭐️⭐️⭐️⭐️ read for me!! I loved it and cannot wait for book 4!

I have read all of Stephen's books, and they keep getting better; the storytelling gets richer every time. You don't need an interest in historical wartime novels (I certainly am not generally interested in them) to enjoy them; they're great character-driven books. They focus on the human impact of conflict, and that makes them warm and engrossing even when dealing with terrible situations.
The change of setting, from the countryside to London, worked really well to keep the series interesting. The experiences of those in the capital are so different to those in rural parts of the country, so this gave a new insight to be shared. The descriptions of the hotels and Lyons teahouses were excellent, and I could see it all so clearly. Also, being able to include that amazing community spirit, that 'we're not going to let them get us down' approach that Londoners had, to the story was fantastic to read.
As always, Lady Margaret stands out as my favourite character...what a broad! I imagine there was a whole host of women like this whose contribution to the war effort was incredible. She is so three-dimensional in the way Stephen has created her.
Another great instalment in this brilliant series.

After a difficult start, young evacuee Frankie is making good progress at John Cook’s farm, but like most of these children he still a little homesick. A party for Frankie’s birthday provides the perfect opportunity for him to return to London for the day to see his folks, but Cook quickly discovers all is not well.

A nice bit of variety in the series as Cook and Margaret follow different story threads than never come together. Running two entirely separate stories works well and allows for a comprehensive snapshot of life then, but without ever feeling forced. It is a fictional story that manages to capture the social realism of the time like a good history book.

Margaret’s life is now the world of espionage. She has been tasked with gaining the confidence of high-ranking detainees and prisoners of war and setting up her own network of double agents. She’s a woman who can take care of herself but now she faces hidden enemies. Internment appears cruel and paranoid now, but then there was a genuine fear of ‘the enemy within’ with the country facing disaster. These feelings are conveyed with sensitivity and balance by the author.

Cook faces the reality of bombs falling on the capital, a world away from the safety of his farm in Sussex. There are some great graphic scenes of the air raids and their aftermath, which inject a sense of danger, the terror of those caught up in them and the horror of the personal cost. A sense of inevitability is creeping in; London is going to be destroyed. They also provide an outlet for Cook’s selfless heroism.

Frankie’s sister Ruby appears to have gone missing, so Cook promises to investigate. At first, they believe that she was killed when the bus she was on was hit by a bomb. Cook is unconvinced and is drawn into the world that takes place in the blackout. A world of prostitution, exploiters, the black market and crime. Whilst the Blitz drew people together, it was also a chance for others to exploit and make a ‘quick buck’. The position of ARP warden becomes coveted, as Cook is later told being able to display those letters on a car is like having the keys to the city.

Despite having so much in story moves briskly and is always engaging. The concluding scenes are a surprise (well they were to me) and introduce a classic ‘race against time’ scenario with all its fluctuating emotions. It ends with a cleverly planted seed for books to come in the series, which is going keep readers engaged in the series, though I think many will be hooked now already.

I was very much looking forward to reading The Blitz Secret having really enjoyed books one and two in this series.
John Cook is a brilliant, no-nonsense character. A bloke I would definitely want on my side. He reminds me of Reacher. I picture Alan Ritchson when I read these books.
In this book we see Cook spending most of his time in London. Now, I didn’t live through the blitz, but I feel like I did after reading this book. I’m glad I really didn’t. It must have been terrifying. I was particularly disturbed by the cutting of corners where building air raid shelters was concerned. I would not be at all surprised if that actually happened!
I was mortified by the behaviours of some of the characters in this book. People who should have been safe to trust. It just goes to show, you never know what might go on behind closed doors. What Ruby goes through is nothing short of horrific!
I’m impressed by Cook’s determination to succeed in everything he does. He’s like a dog with a bone who won’t let go. I admire this so much, as so many other people would take the easy way out and just give up at the first hurdle. He will not rest until he gets satisfactory results. A man on a mission!
Lady Margaret is brave. I couldn’t do what she does. I’d be useless!
There is so much tension throughout this book, I don’t think I relaxed once. Fast paced and full of suspense it kept me on the edge of my seat and the ending left me well and truly intrigued for book four!

Really pleased to see the return of John Cook and Lady Margaret, I’ve been looking forward to seeing what happens to them next.

John Cook is on the way to London, not his favourite city, with Frankie, his evacuee, to see Frankie’s mum as it’s his birthday and there’s a party for him. Worryingly, Frankie’s sister, Ruby, doesn’t come home from work and then there’s news that a bus has been blown up during a German bombing raid, a bus that Ruby could have been on. John, being John, gets involved in in looking for Ruby and uncovers more than he bargained for!

Meanwhile Lady Margaret is in France, masquerading as Lady Miriam, is she a traitor or a spy? Once her true identity is uncovered, she escapes back to England but is she now a spy for Germany or a double agent?

Another thrilling read by this author, full of twists and turns, blind alleys and red herrings, with vivid characters jumping off the pages. Another thing I really like about these books is the fascinating insight into how people tried to live as normally as possible during the war. Their lives and the changes they had to adapt to run as a background to the overall narrative.

Although this can be read as a stand alone book, I think the main characters, in particular, will resonate more if you have read the first 2 books, which are just as thrilling as this one.

Thanks to Net Galley and Hodder and Stoughton for an ARC for my honest review.

Thank you to Net Galley for this Arc in exchange for an honest review.

Firstly I am very much enjoying this series and this book was no exception. Although it was a little odd to see Margaret and Cook separated for a large chunk of the story I enjoyed the plot and the elements of the story. I've been inspired to research the history of both World wars and I want to thank Stephen Ronson for the list of books provided at the back of the book. The pacing was good and I found the first chapters very intriguing. The description of the Blitz in London is very raw and real and the characters are still as vivid as ever. I'm always draw in by the descriptive prose in this series. It was interesting to see Cook and Margaret separated but I like this in books as it is interesting to see how the characters engage and interact in isolation. I'm excited to see where the relationship between them grows. A tense and twisty ride to the final chapter. I loved the reference to Ian Fleming in one of the early chapters. I can remember an Agatha Christie quote in another book. A definite book of the year.

Book 3 in the John Cook and Lady Margaret series but I think it can be read as a standalone as it makes sense but better read in order, Cook and Margaret have been through a lot together and you can tell via each book.

This one is set during the Blitz and you can tell how much research has gone into the setting, characters and storyline. Cook is on the hunt for a missing woman named Ruby. A real wild goose chase, looking for clues and people that may know her or that may have seen her.

I really like how Stephen creates likeable characters, ones you care about and want to look out for. The Blitz must have been a scary time, as was other times in the war but never knowing if you'd get home safe. Anderson shelters popping up here, there and everywhere in gardens but quick builds aren't up to standard.

Margaret is on her own mission to uncover secrets of a different kind bur she has to be careful as you never know who knows who.

Looking forward to book 4 and seeing where it takes us! From Sussex in the previous books to London in this one, where to next?

The third book in the John Cook series. Usually set in the Sussex countryside this time Cook finds himself in London with evacuee Frankie. It is the beginning of the Blitz and Cook is looking for Frankie’s older sister Ruby who has disappeared.

Briefly, Ruby was thought to have been blown up when a bus received a direct hit. However, her body hasn’t been found so Cook starts digging into the murkier side of London and in particular East London Docklands which is a scene of utter carnage as the bombing raids wreak havoc and destruction. In the meantime his old flame and spy Lady Margaret, last seen rowing out to sea to meet a U- Boat, returns to the scene but with a different mission.

This is a story which doesn’t try and disguise the horror of the destruction in all its graphic detail but also shines a light on the bravery and heroism of those forced to endure it. I’m enjoying the Margaret character a lot and we are still waiting to find out the truth about her. A another very enjoyable read in this historical/thriller series.

♥️Thank you @stephenronsonauthor for the opportunity to read the ARC of The Blitz Secret. This is my honest review. All opinions expressed are my own.

My thoughts:
John Cook reminds one of Jack Reacher….a Jack Reacher in 1940 Britain.
I have to say author Stephen Ronson gives a wonderful historical research of 1940 Britain. I found myself fully immersed in the history aspect.
But…..I have to say something about the pacing of the story. I am not sure who proofread the story….but, I found myself very surprised in the “disjointness” of the story. Please know, in no way did this take away from me liking the book nor, reading on and on. I just felt a bit confused with the way the chapters DID NOT flow consistently. Maybe its just me 🤷🏼‍♀️
I have read the previous books in the series and feel the flow of those books were more relatable.
Overall, I enjoyed reading The Blitz Secret….the characters, the historical research and plot were quite intriguing. For me, my only critique,the pacing seemed off and confusing at times.

I’d read the authors previous novels in the series and really enjoyed them immensely when the new one was available for a pre-review on NetGalley UK. I had a message from the author who pointed me in the right direction so I could request it.
In this novel, we meet again John Cook the British spy working incognito in a farm in Southern Britain and Lady Margaret his spy friend . very soon after the end of the last novel. This is the time period when Britain was expecting a massive onslaught of bombing from the Germans and potential invasion. There are scenes set in the London blitz which are visual exciting and at the same time horrific. I can’t help thinking that these books would make a fantastic TV series.
There is a very exciting scene pretty near the beginning during the blitz when the main characters are in a small boat on the Thames is highly visual and very enjoyable
These novels are an easy and immersive enjoyable read. I sat down in the garden with my kindle and a cup of tea and gobbled it up thoroughly enjoying it and I can’t wait to see what happens in the next novel. There’s something very British famous five meets Dick Barton and they all go on a thoroughly exciting adventure in the middle of the bombs dropping in central London during the blitz of World War II. What’s not to love about this? There’s a subtle love story buried in there which I quite enjoyed And I loved the addition of the East End gangsters in the story. I also enjoyed the settings in famous London hotels.
I recommend these novels for those who love exciting adventure stories each book works well as a standard line but reading the series has another level to the characters.
I read an early copy on NetGalley UK.
The book is published in the UK fix November 2025 by Hodder and Stoughton

This is the third in the series set during WWII and featuring John Cook, for me is the best so far. This is thriller, gripping in its construct, I was totally absorbed in its compelling character driven narrative. It has a different feel possibly as the action mainly takes place in London.

As read it really embodies the feel of London during the war, capturing that sense of looming terror at the thought of the Germans invading our shores, in a tense edgy thriller,

Superbly character driven, you can picture each in your minds eye, so well rounded, you can see how they fit into the narrative and the location, colourfully drawn out.

At first you start to think that the plot as far as Cook is concerned is straightforward a search for missing woman, however, the author blindsides you beautifully here and has created a meticulous and richly layered plot which will throw Cook into situations upon which he seems to thrive upon. Meanwhile for Margaret the dangers and risks are far more real, the quality is in the the layers are peeled back and the plot revealed.

Throughout the book you get a real sense of time and place, the author really captures the little things which give the story that feeling of realism. It deals more with the darker side of the war as London is bombed on a nightly basis, but through the pervading darkness there is a light which shines in the people. There is also plenty of heart and emotion woven into the narrative.

As a read you can take in the sights and sounds of London life almost as though you are there on the page living and breathing it all, such a superbly descriptive read.

Wonderfully paced with plenty of twists and turns along the way, packed throughout with drama and suspense

Stephen Ronson has proved himself to be one of the best thriller writers around writing about this period, there is a vibrancy and richness to the detail and feeling within the books, You can see the research taken into the period and how this is borne out on the page

Highly recommend. A taut and entertaining thriller which had me hooked from first to last

John Cook takes Freddie back on the island, Wapping, for his birthday, so he can be with his family. When his sister, Ruby, can’t be found, Cook takes it upon himself to look for her. With bombs dropping day and night, London is not the ideal place to be.

Lady Margaret is still in Germany, but she knows that the Germans are onto her, will she be able to make it out of there in time?

This is an informative and interesting series. The author’s writing makes you feel as though you are there, I found myself tensing each time a bomb was dropped.

The characters are great, and I have a soft spot for Freddie. I’m looking forward to seeing where Lady Margaret’s character leads. Cook always manages to get involved in things that are nothing to do with him, but it shows how much he cares, even if he doesn’t particularly care about himself.

I have enjoyed the three books in this series and continue to look forward to reading more.

I received a copy of this book from the publisher.

Took a little while to get into probably because I had not read the earlier books in the series.. The author vividly paints a picture of London in the early days of the blitz which is realistic and shows the hardships endured by a population totally unprepared for the harsh realities of a war fought from the air.. Cook, a Sussex farmer, with a history stretching back to WWI is searching for a long women who disappeared during a heavy night of bombing.His search takes him into the criminal underbelly of wartime London and puts his life at risk. An aristocratic spy, once his lover, makes an appearance in a subplot (once again reading the novels would have helped).
Although I found this to be an entertaining read I was not able to fully engage with the mai characters. In my youth this story would probably have been called “ A Rip-Roaring Yarn” and fits that bill very well.
Recommended for readers looking for a WWII historical novel and strong heroic lead character.

Did I miss something? This was one of a number of books in a series, which without reading, makes little sense of the backstory for the main characters; sadly this lack of knowledge clouded the story for me. Cook seemed out of place amongst the inhabitants of London, with his worldly experience whilst he hunted down Ruby in a corrupt and dangerous setting. London was under constant threat from German bombs at the same time evil lurked on the streets. Espionage is rife as too are the gangs and murderers. The author has made good use of his research of the subject, making it an interesting read from a historical perspective.

A disappointing read which didn’t really meet my expectations or the positive reviews of others.

My thanks to NetGalley and the publishers for this ARC for review.

The Blitz Secret is the third book in this series, and NetGalley said it is not mandatory to read the first two books before reading this ARC. I signed up on the review panel hoping to get some good WW2 revision.

To be honest, this story disappointed me. While the author created a good canvas to build his story on, the endless focus on the protagonist and creating that aura around him throughout the book was a bit of a put off. It appeared to me that the author spent more time on the main character than the story itself.

And the incessant reference to the protagonist's surname peppered on every page was annoying at best. 'Cook said, Cook looked on, Cook nodded, Cook didn't answer'. I give up.

This is my favourite John Cook book to date!

It's the third in the series but can be enjoyed as a standalone. It took a little bit to get into and I wasn't as invested in Margaret's parts of the book, which was a surprise since I was desperate to find out more after the end of book 2.

John in London was a different story and I was absolutely hooked. I kept getting grumpy at life for interrupting my reading as I didn't want to put it down.

Set in the 1940s during the Blitz bombings. Cook, who hates the city, ends up in London investigating the disappearance of a young woman. Meanwhile Margaret is a spy... but for which side?

With the larger picture of the Blitz, spies, food rationing and the war this book is hauntingly powerful. Cook's character shines through once again; he could easily have not bothered searching for Ruby at all. A girl he doesn't even know. But instead he carries on, even though he's risking his own life being in London while the bombings are happening.

One of the many things I love about Stephen's writing is that (judgement allowed but hate isn't 😜) usually when I see the word war on a blurb I put the book back as I tend to find them boring and depressing. But Stephen's are completely different.

The historical detail is incredible and clearly well researched. And although it can be sad because these things happened and it's awful...I also feel like hope shines through. With characters like John who fight for what's right and aren't afraid to get their hands dirty. Hope that even when things are darkest and every day may be your last: hope matters. People and family matter. Love matters. And what you do and the impact you can have? It definitely matters

This is the third book featuring John Cook and Lady Margaret. It's a welcome return to seeing how their lives are now. It is set mainly in war torn London around September 1940. I knew this would be filled of brilliant historical events and you can feel the Blitz Spirit come through the writing. John along with evacuee Frankie go to London to visit his family for his birthday. Meanwhile, Lady Margaret is undertaking a dangerous mission in France. It was engrossing, full of twists and turns, plenty of action, a roller-coaster of ride, and unputdownable. All the subplots wove together seamlessly to an unforgettable conclusion.

The third in the Cook series of books brings us to a war torn London, under attack from the enemy and each other. Known as The Blitz Spirit this book explores the reality of war and the mystery of a missing girl. It was a fast paced read and my love of all the characters continues. Margaret is a complete enigma and I’m loving the web being woven around her. Action packed and also sentimental at times this strikes a great balance for the reader. Thank you once again for inviting me to read on this outstanding series.

4.5 stars, only rounded down for a few scenes I found slightly implausible (Cook on the boat, for example). However, this is an excellent book - clear historical research, good characters, great plot and pacing. I whipped through it in two days, as it really kept my attention and interest. Would definitely recommend for anyone who likes pacy historical crime.

I received a free ARC copy of this via NetGalley and the publishers in return for an unbiased review.

This is the third in the series but can be comfortably read as a stand-alone. I can’t comment on how historically accurate it is but, based on my knowledge from school, it was mostly believable. I could picture the scenes depicted and sense the emotions portrayed, and there were some great suspense moments. Possibly a few too many characters, at times I was forgetting who someone was and their role/place in the story (but I’m used to smaller circles of characters). Overall a captivating read.

The Blitz Secret deserves each and every one of the five points on this five star rating. Stephen Ronson provides, as he has in his prior books: 1) a clever plot, 2) memorable characters, 3) intrigue and suspense, 4) engaging narrative, and - most importantly, IMHO - 5) a sense of what folks living through the Blitz, fearing the imminent Nazi invasion of their island nation must have felt. Highly recommend to all who love the WW2 historical fiction genre . and all who wonder if they might.

I enjoyed The Blitz Secret although I felt as if it was a bit disjointed. This may be due to my not reading the other prior books of the series although it can be read as a standalone.
It has a good plot and is a well researched topic by the author. I think most who have read the other books in the series will enjoy it greatly.

The story line is strong, abuse, attempted murder in the WW11, very descriptive and true to timeline which I loved.
My only dislike was that it chopped and changed every chapter which I found very confusing and challenging to keep the script flowing. But did like the story and what it was aimed for.

This is the first book I've read by this author. The Blitz Secret held my interest throughout. How Londoners coped throughout the Blitz during WW2 and crimes that were still being committed. I hadn't realised this was part of a series, yet it did not spoil my enjoyment , but I'll be looking for earlier books and looking forward to reading further books by this author .

I didn’t realize this was in a series until after I started reading it. I would recommend the books be read in order to fully appreciate the story. It does have a lot of tension as London is being bombed and watching how the characters reacted to that very scary time.
