Thanks to NetGalley and Sphere for the advanced copy of this title in return for an honest review.

I have been so excited by this book, it sounded so much fun.

I love that cosy crime has become so popular recently and I cannot get enough. And I love having older protagonists too, and Margaret was instantly gorgeous and I loved her. I don't like how people treat her, particularly her family, especially her daughter. It's like, just because she's 89, that means she is obviously too old to know what she's doing. No-one (bar her Grandson) seem to believe she could possible know what she's doing, but that made her even more likeable for me.

I read another review that said this was like Elizabeth Is Missing crossed with The Marlow Murder Club and I couldn't have described it better myself. That's exactly what it is - and those other two books are fabulous as well.

This had my attention from the very start to the very end. The pacing was good, the characters loveable, a fun premise; it was easy to read, quick, well written and just a delight.

It is a crime novel yes, with its thrills and spills. But it's also about friendship, secrets, grief, loss, ageing, health, family, loneliness, peer pressure, trying to fit in, and love.

I have found that, generally, with cosy crime I'm able to figure out, or get close to figuring out, the whodunnit, more so than with a thriller. But I had no idea with this one. I had some suspicions but the reveal is so well woven in and hidden.

Occasionally I found the dialogue a smidgeon stilted, but that's a minor point and didn't impact the enjoyment of it, but as this is an honest review, I have to mention everything I thought.

It doesn't really have legs for a sequel or a crime-fighting series but it does bode well for Richard's future work and I'll definitely be keeping my eye out.

I read it in less than 24 hours, it was fantastic, and is a really wonderful debut. Who knew that an 89-year-old and a teenager would make the perfect crime-fighting duo?!

Compassionate, although heartbreaking mystery where the real villain is Alzheimer’s disease. Not cheery stuff, but somehow not depressing—it even managed to offer some hope and humor.

Margaret's neighbour and friend, Barbara, is found strangled to death on her kitchen floor. Who would want to hurt Barbara, and why? Margaret knows that Barbara told her something important the last time they spoke. But unfortunately, that vital piece of information has vanished in one of the many black holes that are now Margaret's memory. When it looks as if the wrong person might catch the detectives' eyes and be charged with something they haven't done, it becomes even more crucial that Margaret remember her last conversation with Barbara. Will she be able to help? Or will Barbara's words be lost to her forever?

To be honest, I found that as the story went on, the mystery surrounding Barbara's murder took somewhat of a backseat for me. I was far more invested in the relationship between Margaret and her grandson, James. It was so wonderful to see how James would try to help Margaret restore her memories, or try to cope with her new reality. He was such a great support to her, and just like him I wanted to find answers. Not necessarily about Barbara, but about the mysterious Uncle Harry, what Margaret was hiding in her desk, and things about her past she seemed so reluctant to talk about.

I must admit that 'The Margaret Code' turned out to be a far more emotional read for me than I had expected. Having witnessed a grandparent with dementia myself, some of the things Margaret goes through hit a little too close to home and there were various moments where I nearly reached for a tissue. Incidents that were all too familiar, like leaving a gas cooker on. The inability to recall something that happened mere hours ago, yet being able to tell you whatever you wanted that happened decades ago. Those who know, know. Luckily for me, as well as for James, there are also many, many fabulous memories to cherish forever.

Obviously, Margaret is one of those characters you just want to wrap up in a warm hug. But I also felt like doing that for her daughter, Shirley. She has so much to deal with, and taking care of Margaret is becoming more and more difficult. There are a great deal of things to look out for and Shirley can't be there 24/7. Did Margaret lock the door? Did she turn off the taps? Is the neighbour Shirley relies on trustworthy? There are countless pitfalls, but there are also only so many hours in the day and Shirley is stretched quite thinly. I appreciate that the author tried to bring that to the reader's attention, as well as the more complex decision on whether or not Margaret should be in a care home.

I didn't quite figure out the final reveal or solve Barbara's murder. One aspect in particular I thought was very well done, although, in hindsight, I also felt I should have picked up on it. I would have liked to have learnt far more about Margaret's past, her marriage to Arthur, her life in general. I hope she told her grandson all about it. He can be her memory keeper, and maybe tell her story some day. In the meantime, I'm keeping Margaret safe in my own memories and I'll be sure to remember her "famous" words : mustn't grumble.

This one touched close to home as I know someone who is dealing with dementia. I loved having a glimpse into Margaret’s mind and her frustrations with her slipping memories. The story held me captive. I wish there was another book!

This was a little different murder mystery book. An elderly woman and her grandson are determined to solve the murder of her beloved friend and neighbor. It contained some comedic relief and some detective work. The concept of it was intriguing but overall it was just an average read for me.

Another novel where our main character is an elderly lady - very much in the ‘Elizabeth is Missing’ vein. Margaret is 89. She has been widowed for a year and still lives alone in the house that she shared with her husband, Arthur, in a street where most of her neighbours have also lived for many years. This is a street where everyone seems to know everyone else and there are close friendship but there is also the nosiness and fallings out. Sadly, however, Margaret is beginning to lose her memory. When Margaret’s close friend, Barbara, is murdered, Margaret knows that on the day of her murder Barbara told her something important, but she cannot remember what it was. We meet Margaret’s daughter, Shirley, who is trying to cope with the worry that Margaret’s illness is causing. The constant anxiety wondering if her mum locked the door, turned the gas off etc. This is a well written exploration of the effect of early-stage dementia on the family and is almost a second plot as Shirley considers what is best for her mum. Margaret’s grandson, James, is 15 and the relationship with his gran is super. He supports her, he encourages her, he tries to help her to remember what Barbara told her and is a vociferous ally when the question of care homes is raised. These two together, gran and grandson, set out to investigate the murder because they know that police have the wrong suspect in their sights. Margaret talks to her late husband constantly and in this way she talk to us - we see her thoughts. And we also see other threads in this tale because Margaret is keeping a secret. We learn about Margaret’s past which makes her illness even more sad. We learn about her brother, Harry, who no one ever talks about. These threads all knit together perfectly. There are some humorous moments but there are also some sadder moments and you really feel for Margaret when her memory fails her and she becomes lost. The author tells us that his own grandmother inspired this novel and you can see that in the way Margaret is fleshed out, that relationship must have been very close. This book, as well as being a bit of a murder mystery, is also a book about getting old. It makes you feel so sad for Margaret as she struggles to hold onto her memories, as she fears losing them and forgetting. It also explores the effect on families when a parent becomes ill, when the child has to become the parent. An excellent debut.

A soft story about an old woman, apparently a code breaker in the war although this is never made clear, who fancies herself a detective and along with her grandson starts investigating the murder of a lady friend. Slow to read and simply written, a disappointment of a story.

"Elizabeth is Missing" meets "The Marlow Murder Club" in this endearing crime tale set in England. I loved both books, so the description of the plot immediately grabbed my attention. The story follows Margaret, an 89-year-old woman with early-stage dementia, and is told from her perspective as she shares her thoughts with her late husband and us, the readers.

Margaret Winterbottom has a secret she hasn’t shared with anyone, not even her family. She has lived on Garnon Crescent her entire life and believes she knows her neighbors - until she’s proven wrong. When her best friend next door, Barbara, is found dead in her house, Margaret’s world is turned upside down.

With the help of her 15-year-old grandson, Margaret tries to crack the case, as the police seem to be focusing on the wrong suspects. But as her memory starts to fade, the lines between past and present blur, and she’s unsure of what’s real. Misplaced objects only add to her confusion. As the duo digs deeper into the mystery, secrets come to light, and emotions flare.

The story captivated me from the very beginning and held my attention until the last page. I loved the book, and Margaret, in particular, got under my skin. Her reminiscences of World War II, her moments with her late husband, and her bond with her grandson were incredibly touching.

The author mentioned that the story was inspired by his own relationship with his grandmother, and his love for her shines through in his portrayal of Margaret. She is a well-rounded, fleshed-out character, and it was easy to become invested in her struggles and her life. When she forgot her way home, my heart truly went out to her.

The book explores themes of loss, the role reversal between parents and children, memory, aging, and the effects of illness on family relationships. The author paints a realistic picture of a woman on the cusp of amnesia and its impact on her family. It was heartbreaking to read about the illnesses of aging, and the desperate need to hold on to the present.

The writing is richly detailed, and I could easily picture each character, place, and scene. I loved how Margaret spoke to her late husband throughout the story, sharing her worries and reflecting on her life. Her relationship with her grandson was heartwarming, and I appreciated his care for her. Margaret’s daughter irritated me at first, but as the story unfolded, I came to understand her better.

By the last section of the book, I had my suspicions about the identity of the perpetrator, but I was still pleasantly surprised by the twists. I also appreciated how the second plotline regarding Margaret’s past was woven into the present-day mystery. The pacing was moderate, which suited the story of an aging heroine.

The style of writing is easy to follow, but the book could benefit from another round of editing. Some chapters start without capital letters, and in a few words, the letter “O” appears randomly in uppercase. Despite these minor issues, I’m giving the book full stars. It’s a compelling debut, and I thoroughly enjoyed it. I recommend it to fans of the genre and anyone who loves crime stories solved by elderly amateur sleuths. I look forward to reading more from this author.

When a neighbour is murdered elderly Margaret Winterbottom, along with her grandson, decides to investigate. Margaret's memory may be failing but she's convinced she knows something that can help her solve the murder - if only she could remember what it is.

I love books featuring aging protagonists and in The Margaret Code author Richard Hooton has created a classic. I just wanted to scoop Margaret up and protect her. Widow Margaret is eighty-nine and fiercely independent, she has lived in the same house for sixty years. The vast majority of her neighbours have lived in their homes for quite a long time too. Everyone seems to know everybody else's business, although some people are a little too nosey.

The murder of long-time neighbour and friend Barbara is a shock to Margaret and when the police appear to be clueless she decides to find the murderer herself. She remembers talking to Barbara the day she was murdered and can recall a fragment of a conversation she had with her that she's convinced is a vital clue, unfortunately, her "senior moments" are becoming more frequent, hampering her from pinpointing exactly what the clue means.

To the reader, it's obvious that Margaret is in the early stages of Alzheimer's. Some of the situations she found herself involved in because of the disease are heartbreaking. We also get a glimpse of the emotional pressure that is placed on families. There are little hints as to Margaret's background. I guessed pretty early on what the background was, although I didn't figure out how it fitted into the plot, and knowing her background makes Margaret's illness even more poignant and cruel.

Refusing to accept defeat, and ably assisted by a grandson who is equally determined, Margaret works her way through a suspect list that involves neigbours, local youths and the window cleaner. If only she could remember her conversation with Barbara! When the puzzle pieces finally fall into place Margaret finds herself in danger but still refuses to give in.

The Margaret Code by Richard Hooton
April 30 — May 2 (Book Review Pages: Facebook | Instagram)

Calling all fans of British mysteries! This is a book for you! I love the way the author wrote this to honor his own grandmother, who he was very close to and suffered her own cognitive decline in her later years. He touches on some subjects that are almost taboo and yet it’s done with such sensitivity. While the mystery is what grips you in the beginning, it’s everything else that keeps the story moving and engaging. I give it a rating of 4.5⭐️ and being his first novel, I look forward to what Hooton comes up with next!

What makes this book so very unique is how the story is told by the 89-year-old protagonist telling the story to her late husband. So it is very much like Margaret is telling you, the reader, the story too. It’s a lovely cozy mystery to curl up with on a rainy day and just get sucked into the English village that I could easily picture. I will warn you, at times, it is kind of sad…Margaret is a widow, lonely, deteriorating physical as everyone does and most heartbreaking of all, her memory isn’t the same as it once was. No one—not even her own daughter—truly believe Margaret when she tells them she saw something. The only person who does is her 15-year-old grandson, James, and he’s determined to help his gran remember in anyway he can.

I loved the relationship between Margaret and her grandson. It was truly precious and makes me want to hug my own 89-year-old Nana then maybe solve a crime with her! Just kidding…but seriously, the relationship between the two of them was just one of the many things that made the book special. Not to spoil anything but as a historical fiction lover, I loved the added details of Margaret remembering her days working as a codebreaker at Bletchley Park during WWII. The mystery element is made even more cryptic due to Margaret’s memory being unreliable and even when I thought I figured it out, the ending left me shocked.

This was an exception debut novel and like I said, I can’t wait to see Hooton’s next book! I think he has a promising career as a novelist ahead of him!

Already the winner of several short story prizes, Richard Hooton is the Master of storytelling. The beginning of each bite-sized chapter catapults the reader into the centre of the action, leaving us wanting to turn the page to the next chapter, and the next one. It’s a well-worn cliché to say I couldn’t put this book down. In truth, I rarely feel that strongly about a novel. But I read this one into the night, unable to wait to find out what happens next.
The book is skilfully written in the second person, from the point of view of 89-year-old Margaret talking to her dead husband, telling him in the present tense what is happening. The use of the second person present tense pulls us right into the action, and into the inner workings of Margaret’s mind – which makes it all the harder to witness this highly intelligent woman losing her mental faculties. The moment when she finally accepts that she will continue to lose objects and forget recent experience, eventually forgetting even who her loved-ones are, is heart-breaking.
The characters in this novel are expertly drawn. No one is two-dimensional. Margaret is stubborn, insightful, caring, and opinionated. Her grandson James is almost pathologically optimistic, with criminal tendencies and a warm, caring streak. Together, they solve the murder of Margaret’s best friend and neighbour, largely thanks to Margaret’s willingness to take risks, and her long history of cracking codes.
This is a gentle crime novel, and so much more. It is about families, about older age, and about declining health. It pulls no punches. This is a novel for all age groups. I’d like to see The Margaret Code make it into the school curriculum. Anyone working with people who live with dementia should also read this book. If that was to happen, I’d like to see 89-year-old Margaret’s face when she found out how she is still making a difference to people’s lives.

4* Sad at times, loving in parts, and also quite poignant and emotional.

What makes this a refreshing tale for me is its believability due to its setting being plain old England. There's no faux gloss, no zooming police cars, nothing cliché or deja vu, just a murder and a some sleuthing, some decent but flawed people that felt real, and of course, a bad guy. Or perhaps, plural, though 'bad' may be a bit strong to describe some characters.

It made me smile in parts and made me sad in others. What was lovely was the love that James had for his gran, despite his mum and dad thinking her a burden and a danger because she was sadly becoming senile. It hit home with me, as I suspect it will with people with parents of a certain age.

Margaret had periods of lucidity that helped her and James solve the murder, but sadly, she was in decline and wasn't in denial during these periods. It was sad to see her struggle and mix the past and present and miss her late husband so much, but it was lovely to see ger constant conversations with him and how vividly she still saw him. Her estrangement from her son was sad, and the reveal about her brother was such a betrayal and shock. But, by the sound of it, he didn't profit from his crimes, so well done, author.

The end is poignant and sad. Margaret's been alone for a year now and it's clear that she's ready to see her husband again, and both she and I thought it'd happen soon. I'm glad I read this book, despite it not being my usual choice.

The Margaret Code by Richard Hooton is a captivating mystery, a story that charmed me with it's unlikely detective duo, tugged at my heart-strings with it's discussion of the elderly's memory challenges, and intrigued me with it's whodunnit.

Margaret has lived on Garnon Crescent for much of her life, it's where she raised her family and spent many happy years married to her husband. But she's finding herself forgetting things lately, and when her friend is found dead Margaret finds herself frustrated with trying to remember what it was that she told her that was important.

Margaret teams up with her grandson to try uncover the clues and retrieve her memory to help solve the case. But with her failing memory, her longing for her husband who has passed, and a daughter who believes she needs to move into a home to be cared for, she's facing more challenges than just finding a killer.

I find myself enjoying the formula of elderly folk being the protagonists and helping to solve the crime. While this particular story was imbued with the very nature of growing old as your memory begins to fade, it is both this aspect of the book which appealed to me and also frustrated me because it made Margaret both a reliable and unreliable protagonist.

The Margaret Code is a thoughtful and at times heartbreaking mystery centered around 89-year-old Margaret, who begins to question everything around her—especially herself—after the sudden death of her best friend and neighbor, Barbara. With the help of her grandson James, Margaret dives into an investigation, even as her memory falters and her family begins to doubt her version of reality.
This book was an emotionally layered read, especially if you’ve experienced a loved one suffer from Alzheimer’s. Margaret's confusion, scattered thoughts, and sense of urgency are written in a way that feels deeply authentic, though at times this also slows the narrative and makes it harder to follow—an intentional choice, perhaps, but not always an easy one for the reader.

I found myself incredibly frustrated with her daughter Shirley (wanted to throttle her, honestly), and suspicious of Matthew—maybe too suspicious, but that kept me turning the pages. There are definitely plot holes and moments where the story drags, but the uneven pacing does mirror Margaret's declining memory in a clever way.

This was a book I could easily put down—but also found easy to pick back up again. The pieces eventually click into place, and while it may not be a fast-paced thriller, The Margaret Code is a solid and poignant slow-burn mystery that sticks with you.

A cozy mystery featuring an older protagonist with memory issues. I knew this one had the potential to gut me, but I had to pick it up. If you've ever had a family member with dementia, you'll be able to identify with Margaret Winterbottom. She's absolutely endearing to the reader, even if her daughter finds her memory issues frustrating. Margaret's neighbor, Barbara, is found dead in an apparent murder. Barbara wasn't just a neighbor, but also Margaret's best friend. When the police question Margaret, she's sure that there is something important Barbara said the last time they talked, but Margaret can't remember what it is. When Margaret's grandson James is implicated in the murder, it becomes even more important that she remember what Barbara told her. 
My favorite thing about this novel was the heartwarming relationship between Margaret and her grandson James. Even though teenaged James is trying to fit in with the boys at school and be tough, he unconditionally loves his grandmother and tries to help her maintain her independence and recall her memories. He chooses her to be the subject of the life story he has to write for school and as they investigate Barbara's murder together, James learns his grandmother had quite an amazing youth and in many ways is still very astute. The author was inspired by his own relationship with his grandmother who died of Alzheimer's, and he captures the love between Margaret and James perfectly. The author has Margaret narrate as though she's relating everything in her confusing world to her late husband, thus giving the reader a chance to see how her mind is putting things together. This novel has moments that are heartbreaking, but it can also be funny and downright thrilling as the plot thickens. Highly recommend it!

Can you call something a cosy crime if the story revolves around a woman's struggle with dementia? It's a tricky one to call, I think. The story does have humour and warmth, yet at the same time there is the awareness that Margaret is struggling more and more with her memory, and it's only going to get worse. But I enjoyed reading this, mostly because I liked Margaret and her relationship with her grandson, so I wanted to see how things would resolve.
From the crime side of things, I was disappointed that it wasn't more clever - when you find out Margaret's history, and where she worked with her husband during the war, I hoped that the puzzle would be difficult, and she would be the only one who can solve it, because of her experience, and it would be marvellous when she did! So from that point of view I felt there was a waste of what could have been a really interesting, tricksy potential storyline. But still, I was interested enough in Margaret to commit to the story, and I enjoyed the ride, even if the murder side of things wasn't all that.
With thanks to Net Galley and the publishers for my advanced copy.

This was a really good book, and I enjoyed it a lot. It wasn't even about the mystery which was still interesting (though I figured it out pretty quickly, though not the stuff surrounding it!), but it was more about the other things. And old woman coming to terms with the fact her memory is failing her, wanting so badly to remember important things. The illness playing tricks on her and only bringing her more fear and uncertainty. But she never gives up, doesn't let it define her or stop her. The relationships in the book are really interesting too. Especially the relationship between Margaret and her grandson James who never gives up on her, never thinks she can't do anything, including solving the mystery and restoring the memories that will help to do that. It was really beautiful to read. There's sadness in reading what the illness of Alzheimer's slowly does to someone, seeing the confusion and fear it can bring in moments. How relationships are affected. But happiness in the good moments, the bonds that are still there. A definite worthwhile read.

“The Margaret Code” by @rjhooton.

⭐️⭐️⭐️⭐️⭐️

Firstly what an incredible book! In my opinion this book has a really good representation of Dementia/ Alzheimers. My granny had it so I know what it’s like somewhat from a personal experience. Seeing the person you love go through it. So knowing that Richard inspired this book by his relationship with grandmother was really lovely.

The story was beautifully written. There were some really funny and light moments breaking up the murder, grieving and darkness. Loved this detective duo trying to solve the murder of Barbara. What secrets and twists that unravel because of her murder was so good and kept me wanting to read more and more. It was interesting seeing how different the characters were dealing with Margaret’s Alzheimers.

The characters were fantastically written. I really enjoyed Margaret talking and asking questions to her husband Albert, who passed away not so long ago. It was sad but really sweet. Margaret and James’ relationship was one of my favourite parts, he’s a nanny’s boy like myself.

The last few pages and lines… WOW 🥹
One of my favourite books this year.

One of my favourite things about the murder mystery books I read is when an older (elderly) character(‘s) who’s not really a detective/police.. whatever, is one of the main characters solving the crimes…

I love them that much maybe that’s who will be a main character in my murder mystery book I plan on writing 🤫.

Great book! Interesting premise and very readable: 'cosy crime', but with just the right amount of real life edge and a loveable and memorable protagonist.

The book is narrated by 89 year old Margaret. I loved spending time with her - finding out about her interesting past, her love for her late husband Albert, and her cutting wit. She felt realistic, especially as her memory issues progress and she's never quite sure what is and isn't real, and those around her (apart from grandson James) become more and more patronising.

Her age and everyone's assumption that she was muddled due to this increased the mystery but never felt like a plot device - her denial and fear felt very real.

If I had one criticism it would just be that the crime felt too neatly wrapped up at the end, though it was a satisfying resolution after I'd galloped through the book and I'll be looking out for other books by this author.

The Margaret Code is a heartfelt mystery that blends memory loss and the complexities of lifelong friendship. When Margaret’s neighbor and closest friend is murdered, the police struggle to piece together what happened—but Margaret may already know the truth. The problem? She’s battling dementia, and her fragmented memories make her an unreliable witness. As her grandson James steps in to help, he finds himself uncovering more than just the details of the crime—he’s also unraveling long held secrets from Margaret’s past.

This book had cozy crime/mystery vibes, but what really stood out was the emotional depth. Margaret’s struggle with dementia made for an interesting perspective, keeping me engaged as she drifted between lucidity and confusion. And her relationship with James? So heartwarming. At its core, this is just as much a story about grief, family, and the impact of memory loss as it is about solving a murder. A compelling and bittersweet read—solid 4 stars!

Margaret is eighty nine, she has been living in her house for many years and it holds the memories of her beloved late husband. She knows that her memory is not what it was and there are getting to be more senior moments than she is comfortable with but she is fiercely independent and wants to stay in her home among her memories and her neighbours who have also been there many years. When friend & neighbour, Barbara, is found strangled in her kitchen, it is a dreadful shock. She knows that before her death Barbara told her something important - if only she could remember what! Along with her grandson the pair attempt to find out who killed her friend.

I loved this book! I loved Margaret and mourned with her for the sharp mind that is now getting more clouded. The relationship with her grandson was lovely. They made a great sleuthing pair. I'd love them to have another case to solve. Thanks to Netgalley & the publisher for letting me read & review this book.

This is very much a character based murder mystery set at a gentle pace with Margaret aged 89 (the main character) trying to find out who would kill her elderly next-door neighbour whilst struggling with the onset of dementia especially the memory loss.
It’s a lovely story and one that I enjoyed very much and I particularly loved the relationship between Margaret and her grandson James, and also the reminiscences of her life with her deceased husband who she missed very much and still chatted away to him in her head.
All in all I loved the book it was different and beautifully written and I hope to read more from the author in the future.

The Margaret Code is a thoughtful mystery that gave me strong Elizabeth is Missing vibes, with its blend of intrigue and the exploration of memory, loss, and identity. The writing style is steady and measured, which suits the subject matter well, and I found myself drawn into Margaret’s world.

The central character is engaging and believable, with her perspective adding both poignancy and tension to the unfolding mystery. The supporting cast bring texture to the story, though it is Margaret herself who gives the novel its heart.

This is not a book that races along, but rather one that lingers and encourages reflection, making it a solid and engaging read.

3.5 stars rounded down. This sounded an interesting and character-led mystery novel, and to be fair it did deliver both of those things. It was just that it was very slowly paced for my liking, and Margaret’s constant talking in her head to her recently dead husband and her internal monologues were a little overdone for me. Thankfully the mystery did wrap up by the end of the book in quite a nice way - and I think it would probably appeal to people who like the Thursday Murder Club series, though there are fewer characters here to root for other than really Margaret and Jamie.

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

I got an ARC from our local bookstore.

I found the pace of the book quite slow but that did fit in with the theme of dementia stealing one’s thoughts.

Margaret brought tears and warmth to me as I read her struggles with the change in her life brought about by dementia. I volunteer with our local Alzheimer’s Society and give relief to caregivers by going into the home. I can understand how aggravating it can be to lose one’s words.

The relationship between Margaret and her grandson, James, was delightful. The way they supported each other in their determination to solve the murder was lovely.

I really do love a cosy mystery and 89 year old Margaret and her grandson James really crept into my heart. Their relationship was so sweet and I loved that James tried his best to support his gran in every way. It's also a poignant read because Margaret is dealing with the early onset of Alzheimer's which makes her an unreliable protagonist at times.

I loved her grit though and her back story about being a code breaker and how she and her late husband met was so interesting, I would've actually loved more of that story too. An enjoyable read and one that'll definitely have you rooting for the sleuthing duo that is Margaret and James or Batgran and Robin as James dubbed them.

Well, I read it in one day! The Margaret Code was a twisty little tale. While Margaret's dementia made me stop and examine my own discomfort around her situation, it was a theme that added to the emotion of the story. All the characters and their relationships with each other were well developed, Hooton captured the relationship between Margaret and her grandson beautifully and that bond between grandmother and grandson was very realistic. The plot kept me interested and this was a book I really enjoyed reading.

In this mystery, an older woman is grieving her lost husband when her best friend is murdered in the little courtyard kind of neighborhood in London. She investigates the crime and is mostly sharp doing it, although some of the time her slowly advancing dementia makes that hard. This was not a new kind of mystery theme, and sometimes I was bored. But what kept me hanging on until the end was the woman’s relationship with her teen grandson, which was lovely.

I'm writing this review for my 81 year old mom who's not on GoodReads. She LOVED this book, lovedlovedloved it. Read it one day. And my mom is not a cozy-mystery, loves-everything reader. She's picky. I've never written a review for her before, but really wanted to get the word out about this enjoyable read. HIGHLY RECOMMEND.
