Manabu Yukawa, the physicist known as "Detective Galileo," has traveled to Hari Cove, a once-popular summer resort town that has fallen on hard times. He is there to speak at a conference on a planned underwater mining operation, which has sharply divided the town. One faction is against the proposed operation, concerned about the environmental impact on the area, known fo ...more

Sorry Adrian, but I beg to differ, if indeed you felt "Journey under the midnight Sun" was disappointing

Upfront let me tell you that I'm ok for others to disagree with one's opinion. It is natural and bound to happen. But I personally felt JUTMS (sorry for abbreviation) was one of Higashino's best in terms of mystery and plot building

Imagine the two main characters never openly (in front of the reader) meet ever during the novel, yet there is a connection deep and you feel the events and circumstances are driven by them until the very end

I just loved that novel. Perhaps even more than Devotion of Suspect X or Salvation of a Saint(less)

Higashino is a popular Japanese author who writes mysteries emphasizing character and culture. Though by the time I reach halfway through the book, I'm fighting my usual urge to peek at the denouement, there is still something kind of restful about the story. (Besides, I've learned with Higashino that that's ultimately unsatisfying, due to the build of the relationships that make the resolution so hard-hitting). It is the clear prose? The exquisitely polite mannerisms of the characters? The emph ...more
A Midsummer's Equation is the 3rd Higashino novel I've read in 2016. To say AME's not as strong as The Devotion of Suspect X and Salvation of a Saint is akin to pointing out that The Man Who Knew Too Much is not as great a Hitchcock flick as The Birds or Rear Window. AME remains superior to much of what is sold in the crime/detective/thriller category, is an enjoyable and accessible read, and here's why I recommend it:

The story begins with Manabu Yukawa, a physics professor, known as ‘Detective Galileo’ traveling to Hari Cove, a beautiful town with a rich seabed that the company wants to exploit for mining in order to find rare metals but there’s a protest from the locals and environmentalists, arguing that this would harm the oceanic life.

In the scorch of summer, while the sea is illuminated in a million jewels, there still lies darkness after a man is found dead on its shores.

A Midsummer's Equation is a gentle but involving mystery set in a crumbling tourist town by the ocean. The state of decay alongside great beauty mirrors a story of fortunes and good acquaintances turning sour.

I like the main character, eccentric physicist Yukawa, but I do agree with the criticism that his character can be lacking or borderline robotic at ti
After reading a couple of books by Higshino, I know what to expect, and this book was just upto expectations. If not for the cute kid and his homework issues and the way Yukawa dealt with him, it would have been a 3 star read for me.,

I have now finished all three books that are available in English of this series and I gave each of them four stars. That is a testament I think of the overall quality of these books as all three are all superb mysteries. Still even all at the same rating there has to be a favorite book in the series (even if only by a marginal point) and with a favorite also comes a least favorite. So where does this one rank?

Honestly, depending on the day this could be my favorite or least favorite in the seri

The last sentence of this book left me breathless.
Everything I had read throughout this book culminated in this very last sequence yet the author intentionally left out the answer to the equation for his readers to speculate.
Gorgeous prose and the lingering ambiance. I fell - once again - with this book.

Although this book is pigeonholed into the mystery/suspense genre, it reads more like a human drama with the theme of 'devotion' at the forefront.
This book does include a mystery plot that i
This was the first time I felt really close to Detective Galileo. He was there since the earliest chapter, involving indirectly with the case-- unlike the previous Keigo I read, Yukawa only appeared later in the middle of the investigation when Kusanagi and Utsumi came asking for advise. How I love Yukawa a lot to the level I don't want to finish reading this (and at some point I'm afraid to read further cause too afraid Kawahata might done something to him). His friendship to Kyohei in here so ...more

This is so far my favourite book by Keigo Higashino. Perhaps because of the location, a coastal town with wonderful views, or because of the characters a curious preteen and his family. The role Detective Galileo played seemed to be more compassionate than in other books as well.
The mystery in this novel is slowly unravelled and the reader will find it as intriguing and complex as in Higashino's previous novels.
It is all in all a very nice summer read.

I do not get the hype behind Higashino's books. They are by all account good books, well written, and provide an interesting look into the contemporary Japanese culture as it is very well-weaved with the tradition whodunnit. However, I do not find anything path-breaking or spell-binding in them. I would rather read a Murakami book which does a better job at it.

The book is a pretty fast read, it does hold your attention a fair bit but could have been edited better to chop off a good 50-70 pages

I give this a 3.5. With a crime scene by the beach in a small town, this sent a different vibe than Higashino's previous books. It doesn't make it less interesting or slow, as people like to associate country's life to city life, rather it just gives this book a different vibe than the one one usually associate with Higashino. In the book, Higashino finally focused on Yukawa's role in 'investigating' a crime, rather than the opposite in previous books; where he assisted in solving crimes lead by ...more

Reading Higashino thrillers have always been a ride and this book was a ride though less spine chilling.
The mastery of intricacies of the plot and the execution of murders are always the highlights of Higashino thrillers. To add spice to these factors, there are always ulterior motives.
This book have all these, however I found it bit lacking compared to his previous works. Salvation of saint was his best work and compared to that this book is lacking at many places. So if you guys are expecting

The 3rd book featuring Detective Galileo and Kusanagi is a pretty average fare. For one - the crime is neither compelling by motive nor ingenious in execution. And we have too many lucky breaks and backstories to distract from the mystery.

Professor Yukawa is in Hari Cove as an expert at a DESMAC hearing where the locals are voicing their concern for the cove in the face of proposed underwater drilling. He stays at a local inn run by a family with secrets and a visiting school boy who strikes a f

Not only a mother who's willing to go to hell and back to protect her children, a father is also willing to do the same.
The movie made me weep and the book made me feel agony. The thing about Keigo's books is that they're anguishing, tear jerkers and in the end I'm left bereft, sad and couldn't help but think about the stories.

The less stellar cousin of the Higashino books, A Midsummer's equation did contain most of the elements that made the other 3 books of his that I've read masterpieces. But what it missed was a definitive punch of "I did not see that coming" the way they did. The characteristic winding loop that Keigo takes us through before he reveals who did it or how it was done is still there though. And there was definitely one moment when the slam of "I can see it coming. I make the connection" hit me and t ...more
A teenage boy Kyohei is sent to visit his aunt, uncle and cousin (Narumi) in coastal Hari Cove, a once popular summer resort, famous for its crystalline ocean floor, but sadly in decline. On the train, Kyohei meets the physicist Yukawa (a/k/a Detective Galileo), who stays at his family's inn. There is planned mining, which will help the economy but risk damage to the place's unique beauty. Things go wrong quickly when the other hotel guest is found dead on the rocks, a suspected accident or suic ...more

It is not common to feel a sense of peace and tranquility while reading a crime fiction novel. But somehow Keigo Higashino’s A Midsummer’s Equation provides exactly that. Limited bloodshed, no chasing cars, no cops running in pursuit of criminals, no conspiracy to threaten global peace. A Midsummer’s Equation begins and ends in Hari Cove, a small seaside town in Japan, that would make you want to immediately pack your bags and go there (oh, how badly I want to do that now!).

Unfortunately for me, both my Japanese and Chinese was so rusty that I have to wait a long time just to read this in English. I've already watched the movie adaptation years ago and I'm quite satisfied with both medium. The novel did add a lot of nuances that the movie skimmed.

One of them was the relationship between Yukawa-sensei and Kyohei. I know that Yukawa never like children so it does felt strange at first when he immediately bonded with the boy. The novel provide occasional narrative fro

I don't exactly know what it is about Higashino's writing that I like so much but I always enjoy his books. I like reading about the different culture and his books always have some good surprises in them. This is not my favorite of Higashino's books but it was still very entertaining and well worth reading. I would like to see a little more character development of Yukawa and Kusinagi (spelling? I usually listen to Higashino on audiobook). I don't feel like I "know" them as much as I would like ...more
Professor Yukawa flits about in the background in this murder at an aging declining seaside resort. The book's focus is on the bumbling local police, the professionals from Tokyo and the background behind a 15 year old murder.
The book flows slowly along and the cases are wrapped up with 100 pages to go. But the denouement based on ethics and respect of people's future saves this from being a bit of a bore.
This book took me awhile to finish mostly because my audio "read" was from the library. Midway through my loan expired and I had to wait back in hold hell to finish it. I started it from the beginning and made it my constant companion. Now that it is finished I am lost.

I discovered Higashino last year and he quickly shot onto my favorite authors list. This book had me from the beginning. Was it one mystery or two? Manabu Yukawa, the physicist known as "Detective Galileo" or in this book " the p

Kind of predictive.

But before I put down the review, I have a question for the publishers.

"What is this putting, 'Stieg Larson' of Japan on every cover of the books by this author?"

I've read Stieg Larson and this is my second book by Higashino. They are nowhere close, when it comes to plot and writing style. They both are unique and has their own unique style. And Both are good. But someone up there is comparing lemons with melons.

It’s easy to see why Keigo Higashino is one of Japanese top mystery writer. This man never let me down. Having read 4 of his book, this was very good but it is not quite “there”. A Midsummer’s Equation revolves around the murder of a former detective, whose body had turned up in a small seaside town, Hari Cove. A whodunnit, whydunnit and howdunnit brilliantly riddled together that took awhile for every piece of the puzzle to come together.

While giving the readers the thrill of the murders, Keig

Never say never. And yet, I feel that this is where I draw the line for now.

Keigo Higashino's style is attractive. But it gets repetitive. Partially my fault for finishing four books by him within a span of a month or so.

Keigo Higashino has a knack for getting crime stories right, and this book is no exception. What's special about this book is how carefully the motives are explored, unlike how mainstream crime novels throw open the curtain a bit abruptly.

“There are some mysteries in this world," Yukawa said suddenly, "that cannot be unraveled with modern science. However, as science develops, we will one day be able to understand them. The question is, is there a limit to what science can know? If so, what creates that limit?"

Kyohei looked at Yukawa. He couldn't figure out why the professor was telling him this, except he had a feeling it was very important.

Yukawa pointed a finger at Kyohei's forehead. "People do." he said. "People's brains, to be more precise. For example, in mathematics, when somebody discovers a new theorem, they may have other mathematicians verify it to see if it's correct. The problem is, the theorems getting discovered are becoming more and more complex. That limits the number of mathematicians who can properly verify them. What happens when someone comes up with a theorem so hard to understand that there isn't anyone else who can understand it? In order for that theorem to be accepted as fact, they have to wait until another genius comes along. That's the limit the human brain imposes on the progress of scientific knowledge. You understand?"

Kyohei nodded, still having no idea where he was going with this.

"Every problem has a solution," Yukawa said, staring straight at Kyohei through his glasses. "But there's no guarantee that the solution will be found immediately. The same holds true in our lives. We encounter several problems to which the solutions are not immediately apparent in life. There is value to be had in worrying about those problems when you get to them. But never feel rushed. Often, in order to find the answer, you need time to grow first. That's why we apply ourselves, and learn as we go."

Kyohei chewed on that for a moment, then his mouth opened a little and he looked up with sudden understanding.

"You have questions now, I know, and until you find your answers, I'll be working on those questions too, and worrying with you. So don't forget, you're never alone.”
