Invisible Helix by Keigo Higashino

First published in Japan in 2021; published in translation by Minotaur Books on December 17, 2024

As American crime fiction once did, Japanese crime novels focus on mysteries that must be solved. Modern American crime novelists tend to focus on the elements of a thriller — fistfights, shootouts, chases — with less attention paid to unraveling a mystery. When American writers try to incorporate detection into their thrillers, they too often make a botch of it by favoring sensational reveals over credible puzzles.

Keigo Higashino has become one of crime fiction’s best mystery writers. His books move quickly but they aren’t action novels. Higashino writes traditional mysteries, planting clues that the reader will see in a different light after investigators piece them together.

Invisible Helix begins with a desperate mother who leaves her baby and a handmade doll at the gate of an orphanage. The baby’s father died during Hidemi Negishi’s pregnancy. Without the father’s income, Hidemi felt she had no choice but to give up the child.

In the present, Sonoka Shimauchi works in a flower shop. Her mother, Chizuko Shimauchi, was raised in the orphanage that later employed her. Chizuko raised Sonoka as a single mother. Chizuko met her best friend, children’s book author Nae Matsunaga, while working at the orphanage.

After Chizuko dies, Ryota Uetsuji comes to the flower shop to order floral arrangements for videos he’s shooting. Ryota begins to woo Sonoka and soon they are living together. When Ryota notices that Sonoka always sleeps next to a handmade doll, Sonoka explains that it belonged to her mother. If the doll seems like a Dickensian plot device, never expect the obvious from Higashino.

Things seem to be going well for Sonoka until Ryota begins to abuse her. When Ryota’s body is recovered from Tokyo Bay with a bullet hole in its back, Sonoka becomes the chief suspect. Sonoka promptly disappears with the help of a friend who knows that the police are coming for her. Sonoka’s disappearance hours before the police want to question her contributes to suspicion that she is a murderer.

The investigation of Ryota’s death falls to Chief Inspector Kusanagi, the co-protagonist of this series. He is assisted by his old friend, Professor Manabu Yukawa, whose ability to piece clues together until they form a solution earned him the nickname “Professor Galileo.”

One of Ryota’s most recent outgoing cellphone calls was to Hidemi Negishi, mama-san of a hostess bar known as VOWM. Kusanagi is assigned to interview Hidemi because he is “an aficionado of hostess clubs.” He brings Yukawa, who quickly discerns the true origin of the club’s name. A working knowledge of both Chinese and Japanese is required to figure it out. Fortunately for those of us who lack that knowledge, Yukawa explains how the odd name is relevant to the story.

As is customary in these books, Yukawa solves the mystery of Sonoka’s disappearance and of her husband’s murder in his own way, even if he has to go behind Kusanagi’s back to assure that his own version of justice is done. Yukawa even solves a mystery that changes his life, one that is tangentially related to the murder investigation. Maybe that’s a bit much, but the plot is otherwise nice and tidy, as a reader might expect of Japanese crime fiction.

Events unfold in ways that are different from those the reader will likely imagine. Higashino skillfully inspires erroneous conclusions about the identities of and relationships between key characters. The reader won’t learn the truth until the plot has twisted multiple times. Paragraph by paragraph, Higashino constructs the clever plot that his fans have come to expect.

Hostess clubs are an aspect of Japanese life that tend to fascinate Americans. The “Darwinian world of nightlife” in Japan isn’t explored in much depth, but it adds atmosphere to the story. The ending is in some respects a little sad, a bit touching, but the story is never marred by melodrama.

The Final Curtain by Keigo Higashino

Published in Japan in 2014; published in translation by ‎ Minotaur Books on December 12, 2023

In The Final Curtain, the play’s the thing. The play in question, The Love Suicides at Sonezaki, was first performed in Japan in 1703. Saying that it holds the key to the mystery probably won’t spoil anything for American readers, although it might provide a clue to readers who are more familiar than I am with the history of Japanese theater. In any event, the mystery extends well beyond the play.

Keigo Higashino is the current master of Japanese mystery novels. His plots are intricate but credible. Embedded in the plot of The Final Curtain are troubled relationships between a father and daughter and between a mother and son. As is often the case, the affected children are too young to understand the difficult lives of their parents.

The novel begins with the story of Yuriko Tajima, a woman who finds a job in a small-town bar and stays there for years. She confides to the bar’s owner that she failed as a wife and mother. Perhaps she has found her niche as a waitress/hostess.

Yuriko befriends a customer named Shunichi Watabe. The nature of their relationship is a bit of a mystery to the bar’s owner. When Yuriko is found dead in her apartment, the authorities decide she had a heart attack. Her employer takes possession of her ashes. Watabe gives the bar owner the information she needs to track down Yuriko’s son, to whom the ashes rightly belong. Her son turns out to be Kyoichiro Kaga, the police detective who stars in a series of novels. The Final Curtain is the most recent, both in the original series and in translation.

Kaga isn’t much interested in the mother who walked out on him, but he is dutiful and so agrees to pick up the ashes. When he goes through his mother’s possessions, he finds a note that lists twelve Tokyo bridges, each written next to a month of the year. He doesn’t think much about it. Life moves on.

About ten years later, a woman’s body is found in a Tokyo apartment. Michiko Oshitani was strangled to death. Neither the cleaning company that employed her nor her parents know why she came to Tokyo. The apartment’s tenant, Matsuo Koshikawa, has gone missing.

Detective Shuhei Matsumiya is tasked with investigating the murder. He wonders if the murder is linked to the murder of a man who died by strangulation before his body was set on fire. The murders took place a few kilometers apart but within days of each other.

Michiko managed client relations for her employer. Matsumiya decides to interview all the businesses where Michiko had recent contacts before she traveled to Tokyo. At a retirement home, Matsumiya learns that Michiko believed she recognized an older resident as the mother of Hiromi Asai. The woman insisted that Michiko was wrong, but Hiromi lives in Tokyo, which might have given Michiko a reason to travel there.

Hiromi Asai seems to have had a tragic life. Her mother, Atsuko, felt deceived by the matchmaker who set her up with Tadao Asai. Atsuko remedied the bad marriage by walking away from her family while Hiromi was still in junior high school. As Matsumiya follows the trail of clues, he learns that Tadao jumped from a tall building, leaving Hiromi to be raised in an orphanage. Yet Hiromi Asai went on to become Hiromi Kadokura, an actress and a successful theater director in Tokyo.

When Matsumiya relates all of this to Kaga, who happens to be his cousin, he mentions a calendar on the wall of Koshikawa’s apartment. On each month, someone had written the same of a bridge. Kaga realizes the bridges and months match the note he found in his mother’s possessions.

From those roots, the mystery blossoms. It is a story of assumed identities, missing persons, and a dubious relationship between a teacher and student. Kaga is forced to confront and reconsider unpleasant memories of his childhood as he learns the truth about Michiko’s decision to leave her husband.

Kaga methodically assembles clues as he pieces together the relationship between the two strangulation victims and his mother’s possession of a list of bridges. As is customary in Japanese mysteries, the eventual solution to each puzzle makes sense. And unlike too many American crime novels, Higashino’s plot does not depend on an abundance of unlikely coincidences.

Kaga’s troubled childhood has been a collateral issue in earlier novels. This one brings the issue into focus while helping Kaga come to terms with it. Higashino always makes the drama of human existence important to the story without allowing it to overshadow the mystery. Crime novel fans who prefer the purity of a murder mystery to mindless action and shootouts might want to fill their shelves with Higashino’s novels.

A Death in Tokyo by Keigo Higashino

First published in Japan in 2011; published in translation by St. Martin’s/Minotaur Books on December 13, 2022

A police officer finds a man with a knife in his chest on the Nihonbashi Bridge, leaning against a parapet below two statues of kirin. The artist who created the statutes added wings to the mythical beasts. The man is rushed to a hospital where he dies without identifying his attacker.

The stabbing victim is Takeaki Aoyagi, an employee of Kaneseki Metals. As the police search a nearby park for suspicious persons, Fuyuki Yashima flees from an approaching officer. He is hit by a truck while running across the street. Yashima has Aoyagi’s wallet, making him the leading suspect in Aoyagi’s murder. Although Yashima’s wife isn’t particularly forthcoming with the police, the reader knows that he called her shortly before he died and said that he had done something awful.

American cops would have congratulated themselves for solving the case without exerting themselves. The Tokyo police are tempted to close the case with a finding that the killer is deceased. Fans of Keigo Higashino’s stories about police detective Kyoichiro Kaga will know that Kaga is never satisfied with circumstantial evidence. He wants everything to make sense and he’s not willing to close the case without discovering a sensible motive for the murder. He would also like to find a witness who saw Aoyagi and Fuyuki together before the murder occurred. To that end, Kaga and Shuhei Matsumiya repeatedly walk through the neighborhood where the crime occurred. The search brings them to a shrine in the Nihonbashi Seven Lucky Gods shrine group and the discovery that someone regularly left one hundred origami cranes (all the same color, but each set a different color) at the shrines. Kaga eventually realizes that the cranes are a clue.

A motive appears when Kaga learns that Yashima had been employed at Kaneseki Metals as a temp worker. Aoyagi was a supervisor who may have participated in unethical conduct that harmed Yashima. But why did Yashima suddenly decide to take revenge on Aoyagi? Did they arrange to meet? If their encounter was a coincidence, why did Yashima have a knife? Kaga refuses to declare the crime solved until he has all the answers. And if Yashima isn’t the killer, who did the deed?

The intricate plot involves several additional characters, including members of Aoyagi’s family and Yashima’s girlfriend. Some of the characters learn lessons about accepting responsibility for bad deeds and having faith in the people we love. Higashino constructs the plot like an origami crane, folding the facts this way and that until they reveal something previously unseen. Higashino leaves no loose ends in this police procedural as each clue eventually contributes to the mystery’s resolution. Even the kirin statues have significance.

In that sense, this is a classic detective story, the kind of thing that Agatha Christie and Rex Stout used to write. Mysteries have grown out of fashion in the US, having been supplanted by plots that feature tough guys who give more attention to guns than clues, but pure detective fiction remains popular in Japan. Hagashino is one of the genre’s contemporary masters.

Higashino’s descriptions of shrines, stores, restaurants, and the Nihonbashi Bridge give the story a strong sense of atmosphere. While he was writing for a Japanese audience, his explanations of Japanese traditions open a window into Japanese culture for foreign readers. Higashino devotes a subplot to a Japanese tradition of honoring the dead. Kaga did nothing on the first anniversary of his father’s death and must deal with family pressure to organize a memorial service for the second anniversary. Kaga doesn’t see the point of memorial services, but the brief skirmishes with family members give Higashino a chance to flesh out Kaga’s personality (or lack of personality when he isn’t doggedly solving crimes). Higashino gives more attention to characterization in his Detective Galileo series, but his Detective Kaga books are equally a must for mystery fans.

Silent Parade by Keigo Higashino

Published in Japan in 2018; published in translation by Minotaur Books on December 14, 2021

American mysteries tend to feature outlandish plots or brilliant but unrealistic forensic scientists or tough guys who solve the mysteries with their fighting skills or self-aggrandizing protagonists who can’t stop reminding the reader how much they care about victims. The age of clever but plausible plots and deduction that doesn’t depend on CSI gadgetry has largely passed. Fortunately, readers who enjoy the challenge of puzzling out the solution to a complex mystery can turn to Japanese mystery writers. Whodunit and how’d-he-do-it plots are plentiful in Japan, where fictional detectives use their wits rather than their weapons or crime labs to solve mysteries.

Saori Namiki is a teenager working as a waitress in her parents’ restaurant when she begins taking voice lessons from Naoki Niikura. His wife Rumi encourages Saori to pursue a career in music. Saori sees the appeal of pursuing stardom, but she also enjoys being pursued by one of the restaurant’s customers, Tomoya Takagaki.

Saori disappears one evening without explanation. Three years later, a house burns to the ground. Saori’s body is discovered in the rubble. The body of the old woman who owns the house is also discovered, but she died years before Saori, who died soon after she disappeared.

The old woman’s son, Kanichi Hasunuma, was a customer at the Namiki restaurant who took an unwholesome interest in Saori. Hasunuma’s ties to the house and to Saori make him the prime murder suspect. Two decades earlier, Hasunuma was suspected of killing a 12-year-old girl. Despite abundant circumstantial evidence, Hasunuma resisted the cultural urge to confess, having learned from his cop father that convictions are difficult to win without the suspect’s confession. True to his father’s teachings, Hasunuma avoided a conviction and even received compensation for his detention.

The investigation of Saori’s murder is led by Detective Chief Inspector Kusanagi of the Toykyo Metropolitan Police. Kusanagi was a young detective when he worked on the first case against Hasunuma. Kusanagi hopes he can bring Hasunuma to justice this time. The novel’s true star, however, is Kusanagi’s college friend, Professor Manabu Yukawa, a/k/a Professor Galileo, a character who first appeared in The Devotion of Suspect X and has solved crimes in three other novels, including Silent Parade.

While Saori’s death is the novel’s initial focus, the fun starts with Hasunuma’s death. Was he murdered? If so, how? He appears to have died from natural causes, but Yukawa isn’t so sure. If he was killed, how did it happen? Yukawa propounds one hypothesis after another. Kusanagi dutifully sends officers to look for evidence that confirms or refutes the evolving theory. Many of the obvious suspects have an alibi involving a parade, complete with helium balloons, that the entire community attended.

Once the police settle on a likely means of Hasunuma's death, the mystery requires the killer to be identified. Revenge is the obvious motive, but Saori was beloved by her family, their friends, her lover, and pretty much the entire neighborhood. Just when it seems that the police have identified a killer, Yukawa mentions a fact that isn’t consistent with their theory and forces the investigation to reboot. By the novel’s end, everything the police (and reader) think they know is cast into doubt. The truth is out there, but like any good scientist, Yukawa knows that the truth is found by accounting for every fact rather than jumping to conclusions that are consistent with only some of the facts.

Keigo Higashino’s complex plots are among the best in modern mysteries. Nearly every character in Silent Parade, apart from Yukawa and the cops, is a potential suspect. Higashino gives each character, from Hasunuma to Saori to the various suspects, a sufficiently detailed background to explain why they behave as they do. The unfailing politeness of everyone except Hasunuma makes Silent Parade a relaxing departure from American crime fiction. Mystery fans who appreciate a challenge should appreciate Higashino's work.

Newcomer by Keigo Higashino

First published in Japan in 2001; published in translation by Minotaur Books on November 20, 2018

A woman named Mineko is murdered, leaving behind an ex-husband and an estranged son. The victim was eating rice cakes before she died. Perhaps the person who brought her the box of rice cakes was her killer. The police, however, aren’t sure who brought them, so Detective Kaga begins to ask questions. Kaga is a newcomer, having only recently transferred to the precinct, but his intense curiosity will soon help him discover everything there is to know about the neighborhood.

Naho lives with her father and grandmother, who all work together in the family rice cake shop. The day after an insurance man named Takura picks up a hospitalization certificate from Naho’s grandmother, Kaga comes to the shop to inquire about the time of Takura’s visit. Could Takura have been the killer?

A young restaurant employee named Shuhei bought rice cakes from the shop at the direction of his boss, a man named Taiji. Could Taiji have been the killer? And what about the restaurant manager, Yoriko, who seems to have meddled with one of the cakes? Or Mineko’s friend, who promised to help Mineko get established after her divorce, but suddenly decided to get married and move to England? Are the friend and her fiancé suspects? And why did Mineko move to the neighborhood where she was killed without making contact with her nearby son?

Kaga is Tokyo’s Columbo, trying to add up all the loose ends, make sense of inconsistencies, and annoy witnesses by repeatedly turning up to pose new questions. As he prowls around the neighborhood where the crime was committed, his investigation takes him to a home goods store where Mineko ordered chopsticks, a cutlery shop where she bought expensive scissors, a clock shop where an owner claims to have seen Mineko while walking the family dog, a pastry shop where Mineko was a regular customer, and a handicrafts store where someone bought a top.

Kaga uncovers secrets and lies everywhere he goes, generally involving domestic drama, although the secrets aren’t necessarily relevant to the murder. In his own way, he helps people overcome the burdens of the secrets they conceal. Kaga thinks that finding ways to comfort people in their daily struggles is part of a detective’s job (an attitude that may be unique to Japanese police detectives, or perhaps to fictional Japanese police detectives).

I loved Newcomer’s episodic structure and its atmospheric depiction of a “premodern” Tokyo neighborhood. The story portrays women who are torn between traditional roles and a desire to lead interesting lives in a male-dominated workplace. In a number of the linked episodes, Keigo Higashino also illustrates the family tensions that arise as younger generations depart from Japanese traditions to pursue their own lifestyles.

But this isn’t a social justice novel or a detailed exploration of changing norms in Japanese society. Newcomer is an entertaining version of a Detective Columbo story that weaves Japanese culture in a Tokyo neighborhood into a murder mystery. Kaga is an entertaining character and his self-effacing interaction with a jealous colleague makes him all the more likeable. The plot is equally entertaining. Newcomer is the kind of police procedural that lets the reader follow a chain of evidence while wondering where it will all lead.

I became a fan of Higashino when I read The Devotion of Suspect X. Newcomer cements my fandom. The novel should appeal to fans of crime fiction generally, as well as being a treat for fans of Japanese crime novels.
