Another one of Higashino-sensei's must-read if you're a fan of the Galileo series. My overall review is a 3.8/5 star. It's nothing to be considered a page-turner, nor was it a bad read to be considered a complete skip. My criticism was mainly on the writing towards the second half of the book, where it had great potential for more significant plot twists and details. The storytelling for each character's back story seemed a bit too straightforward for my liking. For context, my favorite books from him are Journey under the midnight sun, and Namiya.
I enjoyed learning more about professor Yukawa's upbringing, his deep bond with detetctive Kusanagi, and also the typical family-oriented theme from all of sensei's novels.
Pardon me for a simpleminded review. It's been quite some time since I've last constructed a somewhat decent paragraph.
I'm definitely looking forward to perhaps rewatching the Galileo series while waiting for some new content.
This year I've read: Newcomer, A death in Tokyo, The final curtain, and Invisble Helix. It's a good Keigo book to end the year with, reaching my goal of 20 books for 2024. I'm excited to read more of sensei's books in 2025 alongside other Japanese novels ;)
Thank you NetGalley for providing me with an advanced ebook, I'm eternally grateful <3

I hadn't read any Detective Galileo mysteries before, so I think I might have enjoyed this one more if I had a bit more background on the characters. I still read through without stopping as the mystery held my interest though.

The body of a murdered man has been found, shot in the back. His abused girlfriend has gone missing, but the man is such a universally unliked character that there are a host of others who might have killed him. The brilliant Physicist Manabu Yukawa assists detectives Kusanagi and Utsumi in their investigation, connecting the complex threads and people involved, including eventually himself.

We don't really get to know any of the characters in depth, just sort of superficial overviews of several women who have faced unfortunate circumstances along with various investigators working on the case.

I enjoyed the twists and turns in this one, along with all the unexpected connections that came together. I don't know that I'd call it cozy but it was sort of a low-stress version of a thriller except for the glimpses of domestic violence. The story held my interest fairly well; it started slowly but gathered steam as it went.

Thank you so much to Minotaur Books for this book to review!

Thank you so much to NetGalley and Keigo Higashino for providing me with a complimentary digital ARC for Invisible Helix coming out December 17, 2024. The honest opinions expressed in this review are my own.

I’ve read a few books by this author. I really love Japanese police procedural and murder mystery books. I thought it was really good. I enjoyed the story and characters. There were some serious topics, so it’s not quite like a cozy mystery. There were some things that I didn’t enjoy as much. I wanted more of a murder mystery. I would definitely check out more books by this author!

I would recommend this book to anyone who enjoys Japanese stories!

A crime which is more about the "why" than the "how".

When the body of Ryota Uetsuji is found in Tokyo Bay it is clear that it is a case of murder. When his girlfriend Sonoka had earlier reported him missing she didn't set any alarm bells off with the police who took her information, but now that he has been discovered dead she is nowhere to be found. No one who knows her thinks that she is capable of having killed him (and in fact she has a strong alibi for the time of the murder) but her disappearance is disturbing. As police detectives Kusanagi and Utsumi delve deeper into the lives of Ryota and Sonoka they are led to an orphanage, a respected children's book author, the owner and head of a hostess club and a physicist who has often helped the police in the past (in his own way, following his own rules). How have the paths of these people crossed, and what about them is and is not relevant to the case at hand? If the detectives can discover why Ryota was killed (apparently many had reason to want him dead) they will be better able to figure out who did it. When no one is being completely truthful and long-buried secrets are woven into the fabric of the mystery, it may take the intellect of a gifted scientist to unravel the many threads and identify a killer.
A helix is a complex arrangement of angles and tangents that form a curve and it plays an important role in the field of biology, which makes it an apt image for this story of intersecting lives, the long term consequences of actions and matters of biological relationships. The characters are complex and flawed, but with few exceptions I found myself understanding and sympathizing with their actions. This is the latest in a series, and although I have not read any of the preceding titles I was able to read it easily as a standalone. There are relationships between the recurring characters which I had to glean as I read along; someone who has read earlier installments would not need to do so. The mystery to be solved in Invisible Helix is not only why Ryota was killed, but also why Sonoka has disappeared and who else is involved in this puzzling case. With plot twists developing just when the reader thinks they have things figures out, this is an entertaining read that harkens back to authors of the Golden Age of Mysteries like Agatha Christie and Ngaio Marsh and their contemporary equivalents like Elizabeth George and P. D. James. i have read several books in another of author Keigo Higashino's series and been very impressed by the plotting, characterizations and writing. This story fell a little bit short in my opinion when compared to those I have read, primarily because the character of Manabu Yukawa aka Detective Galileo seemed to withhold some of the information he discovered not only from the official detectives whom he was helping but also from the reader, making his deductions offscreen to a degree. It is still an excellent story that I highly recommend, covering topics like domestic violence and the pain of surrendering a child to the adoptive process along the way. My thanks to NetGalley and St. Martin's Press/Minotaur Books for allowing me access to an early copy of this book from one of Japan's. bestselling novelists.

Although this is the 5th book in this series, I have not read the previous ones and found this one quite easy to enjoy as a standalone. I am not new to this author, however, and I enjoy his clever, "cerebral" mysteries, which are set in Japan. Invisible Helix alternates between several points of view and timelines. In the present, the body of Ryota Uetsuji is found floating in Tokyo Bay. The young man was shot, and as the investigators delve into his history they discover that he is not well liked, abuses his girlfriend, and blames everyone but himself for his failures. Sonoko, the girlfriend, would be the best suspect has a solid alibi, leaving the investigators with little to go on. One thin lead takes them to physicist Manabu Yukawa, who has consulted for the police department in the past (and is known as "Detective Galileo"), and it is Yukawa who ultimately solves the case. The story held several twists but didn't have the depth I have come to expect of a Keigo Higashino mystery.

Invisible Helix by Keigo Higashino is a fascinating mystery filled with complex characters and intricate connections. The story begins with the murder of Ryota Uetsuji, whose body is found in Tokyo Bay, and suspicion quickly falls on his missing girlfriend, Sonoka Shimauchi. As the investigation unfolds, Detectives Kusanagi and Utsumi call on physicist Manabu Yukawa, or Detective Galileo, to uncover the truth.
Higashino weaves a compelling tale of hidden relationships, traumatic histories, and unexpected twists. Sonoka’s struggles and the secrets surrounding her life make her a deeply sympathetic character. The secondary cast, including an eccentric artist and a hostess club owner, adds depth to the story.
While some coincidences felt a bit too convenient, the clever deductions and emotional revelations kept me hooked. The translated dialogue is occasionally choppy but doesn’t detract from the overall impact. Fans of intricate, thought-provoking mysteries will enjoy this book!
Very grateful to the publisher for my copy through NetGalley, opinions are my own

📚 #BOOKREVIEW 📚
Invisible Helix (Detective Galileo, Book 5) by Keigo Higashino
⭐️⭐️⭐️ / Pages: 281 / Genre: Police Procedural
Release Date: December 17, 2024
🥳#HappyPubDay!🎉

Ryota Uetsuji’s body is found shot and floating in Tokyo Bay. His girlfriend reported him missing a week before his body is found and has since disappeared. As Detectives Kusanagi and Utsumi begin working the case, we are treated to back stories of the struggles of single mothers, abusive boyfriends, and family secrets.

This is the fifth book in the series and the first one I’ve read, but was easy to read as a standalone. I thought it was just an OK mystery. None of the characters really stood out for me. I liked that it was set in Tokyo as it’s one of my favorite places in the world but the writing was a bit stilted. You could tell it was translated English and it was weirdly riddled with English idioms.

The other strange thing is the only place that “Detective Galileo” is mentioned in the whole book is in the very beginning under “Cast of Characters.” Seeing how it’s the Detective Galileo series, you’d think that would refer to the lead detective in the book—Kusanagi, but no, it’s his friend Professor Yukawa, who has a key role in this story but he was more of a side character in this book and not even a real detective. Weird.

Thank you, @Minotaur_Books, @StMartinsPress, and @NetGalley for my gifted copy.

This is an intricate tale with a unique story that keeps you captive!

Sonoko broke my heart in so many ways. She has just lost her mother and now she is living with her abusive boyfriend. Luckily, one of her mother’s friends figures out what is going on and works to get Sonoko out of the situation. But that is not the only one that has her back!

I loved how this tale twisted around this family. The way this novel begins is with someone leaving a baby at an orphanage. This secret follows the characters throughout and it becomes a guessing game.

Now, since this is translated from Japanese, there were a few places where it was a bit choppy, especially in the conversations. This is minor, just something I picked up on.

I received this novel from the publisher for a honest review.

another excellent mystery by higashino!

thank you to the publisher, via netgalley, for providing me with a review copy

This is the fifth in the Detective Galileo series. I’ve read several of Higashino’s crime fiction books, but I was disappointed in this one.

The body of Ryota Uetsuji is found in Tokyo Bay but a bullet wound clearly suggests a murder rather than an accident. His girlfriend, Sonoka Shimauchi, had reported him missing but then took time off work and has disappeared. Chief Inspector Kusanagi and Detective Inspector Kaoru Utsumi lead the investigation and call upon Professor Manabu Yukawa, a.k.a. Detective Galileo, to assist. It is he who makes connections and discovers that Nae Matsunaga, a longtime friend of Sonoka’s mother, and Nidemi Negishi, the owner of a hostess bar, may be involved.

The title clearly suggests the physical structure of DNA, and DNA does indeed play a role. However, it is the reference to DNA testing that leaves me totally confused. What are the chances that samples from a specific person and a random woman would result in a 99.5 percent probability of these two people being related? Sonoka thinks, “He’d taken samples from some completely different woman and her grandmother and sent them to the testing company” and the result “was a ‘99.5 percent or over’ probability of [their] being related.” Am I missing something?

There are so many coincidences in the book and these definitely weaken the plot. Even the description of the book states, “It's up to Galileo to find the nearly hidden threads of history and coincidence.” The revelations about Yukawa’s family at the end rely on a series on coincidences. Everyone has a lost family and secret background. There are three women who gave up children because they were unable to look after them.

Like previous Higashino mysteries, there are secret relationships among characters and connections between past and present events. The problem is that the books have become almost formulaic.

Another intriguing Galileo tale.

The complex situation of a death that goes from at first glance relatively simple to murder, highly involved, and back to its simple root’s is teasingly intriguing.
All very laid back despite the accompanying twists.
A body is found with a bullet in its back. A young woman has a partner she’s reported missing. Now the woman can’t be found. Chief Inspector Kusanagi and his team explore the angle of domestic abuse.
In the mix is an older woman who’s much struck by the younger woman and as time goes on she’s convinced Sonoka Shimauchi is her granddaughter.
Is this a lie or the truth?
The story’s beginnings lay in the past decades back when a young mother places her daughter on the steps of an orphanage accompanied by a very distinctive hand made doll.
It takes Professor Manabu Yukawa (Detective Galileo) to quietly make sense of it all
So much space and time throughout the story to reflect. A pleasing pace.
The translation is spot on, no awkward syntaxes to make you shake your head.

Many thanks to the author and publisher.

Invisible Helix is book 10 in the Detective Galileo series by Keigo Higashino.
A riveting and enthrallingly suspense novel that had me turning the pages so fast!
This book kept me on my toes. I really liked the way this author wrote, it kept me interested and waiting for the next sentence. I couldn't read this fast enough!
Invisible Helix is another mind-bending mystery from the modern master of classic crime.

Keigo Higashino delivers another compelling mystery in Invisible Helix, a twist-filled, intellectual thriller that keeps readers on edge. The story follows the investigation of Ryota Uetsuji's murder, initially suspected to be committed by his missing girlfriend, Sonoka Shimauchi. However, as the investigation unravels, detectives Kusanagi and Utsumi uncover deeper connections involving eccentric characters and a brilliant physicist, Manabu Yukawa—aka Detective Galileo. What begins as a straightforward homicide case soon reveals a complex web of hidden motivations, traumatic histories, and tangled relationships.

Higashino’s signature blend of psychological depth, intricate plotting, and philosophical exploration of fate and coincidences shines here. The clever mystery is driven by Yukawa’s logic and deductions, leading to a satisfying conclusion where nothing is quite as it seems. The secondary characters, including Sonoka's mother figure and a mysterious hostess club owner, add layers to the story, and the subtle yet poignant connections to Yukawa's own past deepen the emotional impact.

Though at times the pacing slows as the characters' backstories unfold, the carefully constructed narrative builds a strong sense of suspense and intrigue. Fans of Higashino’s previous works will find Invisible Helix a rewarding read, with its satisfying blend of mystery and human complexity.

Perfect for readers who enjoy slow-burn thrillers with a psychological twist and morally complex characters.

Invisible Helix is the latest translation of a Detective Galileo mystery. Unfortunately, I feel that this book is the worst book in the series so far. Yawn! I’m not sure if it is the translation or just too many Japanese cultural references but I found this novel to be a snooze fest.

A man is found dead. The number one suspect, who has an ironclad alibi, is missing. In the meantime, Japanese historic bias about single mothers is shown through the intertwining relationships between the novel’s characters.

This book is plot heavy and character light. Most of the people contained in this book can be easily categorized into stereotypes. The conclusion requires some knowledge of Japanese culture, which the translator valiantly tries to explain. Just like comedy, I feel that if you have to explain a key part of a mystery’s denouement, it is a flop.

This author’s works are mostly hit and miss for me. Invisible Helix, unfortunately, was a big miss. 2 stars

Thanks to NetGalley and Minotaur Books for providing me with an advanced review copy.

This book initially drew me in by the title. I did not realize the series I was jumping into. Although this is book 5, I can say you will still understand the story without reading the others. I do want to go back and read the others of this series.
Overall, this story was interesting; I did have some difficulty keeping characters and names straight. The culture and how the book is written was different, and I could tell it had been translated by the way some of the phrasing sounded.
The story itself was full of twists and unexpected turns. This story follows Sonoka and her story. It also follows Professor Yukawa and his assistance in the investigation of Sonoka's boyfriend's murder. I enjoyed learning about Japan's culture and the country's geography. I look forward to reading more of this author's books!
Thank you, Netgalley and St. Martin's Press | Minotaur Books for this ARC. This is my honest review.

Thank you to Minotaur and St. Martin's Press for my advance electronic copy via NetGalley. My opinions are my own.

When Ryota Uetsuji is found floating in Tokyo Bay, shot dead, police detectives Kusangi and Utsumi from the homicide department are immediately suspicious when they realize that his girlfriend--Sonoka Simauchi--is missing, as are her personal effects and clothes. Thus ensues an investigation in which physicist Manabu Yukawa ("Detective Galileo") is called in, an owner of a hostess club is interviewed, and patterns of generational trauma emerge. But if Sonaka has an air-tight alibi, then who could possibly have killed Ryota?

I need more! Twist! Then another twist! I thought I had it figured out but it was even better than I thought. I'm not so familiar with Japanese detective fiction (or Japanese works in translation in general) and I'm addicted! I can't wait to read more of this award-winning author's Detective Galileo series, and watch one of the many films based on his work. He mixes in science, genetics, and intimate partner abuse with the perfect level of suspense. The police aren't presented as bungling egotistic morons, but instead are consummate professionals and human beings who have their own successes and blind spots. Also, I was enchanted by the difference between the Western formula (wait until the end for the big reveal) and this plot (we find out who did it and then the big reveal has more to do with motive and the finer details of the case, which are much more twisty than the act of murder itself). Also, I don't know if this is typical for works of Japanese-in-translation, but I also loved that characters did not have omniscience in regards to the displays of emotion of other characters. Instead, other characters' emotions are observed as we as humans observe them (with limited understanding, only being able to read their body language and tone of voice and not their minds). This has whet my appetite and expanded my understanding of what detective fiction can be!

Triggers: intimate partner violence, death, murder, child abandonment, sexual assault and harassment

What an appropriate name for a murder mystery. As the Tokyo police hunt for the killer of an man found floating in Tokyo Bay, they must trace relationships back for generations. Not all the relationships are what they appear to be, and not all the relationships bear on the case at hand.
Its fun to try to stay a step ahead of detectives Kusanagi and Utsami, and their reluctant consultant "Detective Galileo" as they uncover secrets, and possibly conceal secrets from each other.

I voluntarily read and reviewed an advanced copy of this book. All thoughts and opinions are my own.

Did Sunoko kill her boyfriend? And where has she gone? Those are the two questions that the Tokyo Murder Squad must answer and they enlist the help of physicist Manabu Yukawa, known as "Detective Galileo" because of a tenuous connection between them. This latest in the series will work as a standalone but fans of the series might find it less engaging that previous installments. It's slow, painfully so in spots and I found the relations between all of the women somewhat confusing albeit as it turns out, critical to the case. There are some intriguing spots and it's very twisty but it's hard to care about the characters. No spoilers from me. Thanks to netgalley for the ARC. I've enjoyed Higashino's work in the past and I'm optimistic about future novels from this and other series that he writes.

Book Review: Invisible Helix, Detective Galileo #10, by Keigo Higashino, Giles Murray (Translator)
Published by St. Martin's Press and Minotaur Books, December 17, 2024

★★★★★ (4.5 Stars rounded up!)

"Invisible Helix" (2024) by Keigo Higashino is the 10th and final book of his "Detective Galileo" series (1998-2021). It is the 5th book of the series translated into English and published by St. Martin's Press and Minotaur Books, - huge gratis indeed to Macmillan.

First published in Japan in 2021, 透明な 螺旋 (Tōmei na Rasen Rasen), Invisible Helix, features Higashino's protagonist, research physicist and fictional Teito University professor, Manabu Yukawa, also known as "Detective Galileo", working on, - and often bringing to conclusion, the cases of the Homicide Division of the Tokyo Metropolitan Police headed by Chief Inspector Kusanagi. Loosely comparable perhaps to Jonathan Kellerman's long-running psychological and police procedural series featuring psychologist Alex Delaware working with LAPD homicide Detective Lieutenant Milo Sturgis, though certainly in different worlds.

// "Invisible Helix" (2024), Detective Galileo #10, by Keigo Higashino, Giles Murray (Translator)
Original version "透明な 螺旋 (Tōmei na Rasen Rasen)" published in Japan in 2021 //

Detective Galileo comes to the rescue when the Tokyo Metropolitan Police is stymied by the death of a man found floating in Tokyo Bay, shortly after he is reported missing by his live-in girlfriend.

When they visit to interview her, they find out she'd left town. Then, they subsequently find out she'd been the battered half of an abusive relationship.

And, as it turns out, the abused young woman was aided by two elderly ladies. One, the rueful mother of an abandoned baby, possibly related to her. The other, the long-lost mother of a research physicist...

-----

Higashino's Detective Galileo series finale (1998-2021) draws parallels to the finale of his earlier police procedural series, "The Final Curtain" (orig. 2013) featuring Tokyo Metro Police Detective Kyoichiro Kaga (1986-2013). In both finales, the author introduces to his readers the biological mothers of both protagonists for the first time, although under drastically different perspectives, one of them having met a tragic end. Both protagonists are popular in Japanese literature and filmdom.

Keigo Higashino keeps it down to earth in his writing, a verisimilitude that many readers can identify with. Vicariously for those in the know, a taste of Japan for others. You could almost slurp the ramen, sip an Asahi Super Dry in the neighborhood izakaya. In the streets, alleys, and under the "shotengai", the ubiquitous Japanese covered markets, as he vividly portrays the privileged, the working class, the marginalized in equal light. The nuisances, the colloquialisms, the daily grind of Japanese life; the good, the hard truths and even the dregs frowned upon in society.

Simply pleasurable reading!

Review based on an advanced reading copy courtesy of St. Martin's Press, Minotaur Books, and NetGalley.

Another great book by this author a cerebral police procedural mystery based in modern day Japan.

There is a complicated set of circumstances that lead up to the murder, beginning with a single mother abandoning her baby anonymously to an orphanage which lead to modern day circumstances. The authors inclusion of Japanese culture and social habits makes for an intriguing experience for those who aren’t aware of the culture or habits.

The translator did an excellent job emphasising the aspect of the story that was important and integral to the twists.　This book will keep you guessing, surprise you and take you on many twists and turns to solve the murder.

Thanks to Netgalley and St. Martin's Press | Minotaur Books for this ARC . This is my honest review.
