◆ A genius physicist's lifelong secret "Yukawa Manabu, I forgive your sins!" A man's body, shot in the back, washes ashore in Chiba Prefecture near Tokyo. As his identity is confirmed, the cohabiting woman who reported him missing disappears. Detectives Kusunagi and Utsumi discover Yukawa's name during the investigation. Kusunagi seeks help from his long-time friend, but Yukawa flatly refuses his request. However, as he sees Kusunagi off, Yukawa suddenly offers to assist in the investigation in another way. After visiting the crime scene with Utsumi, she senses that this physicist is hiding something. Yet, the investigation makes little progress, and the police repeatedly miss clues. Finally, Yukawa reveals a long-held secret himself... Yukawa frowned and turned his head towards the sea, then opened his mouth heavily. "How many years have we known each other? Ten years... or more?" "I was in my twenties then." Yukawa nodded. "Is that so? I was going to confide in Kusunagi, but I don't think my friend would be angry if I told you first. Anyway, I said I came as Kusunagi's representative today." (Page 291) What truth has Yukawa been carrying alone for so long? How is it related to this case? Why did he involve himself in the case? The author describes "The Transparent Spiral" as "a work that cannot be explained in one word. It is a story that the author has kept for a long time, finally unveiled. Fans of Galileo will surely be surprised, and fans of Higashino will be even more astonished." The truth revealed through the coincidence of two entirely different cases. Can this be explained by science alone? ◆ A stable detective who is cool but not cynical A work that finally discovers the human 'Yukawa Manabu' The immense popularity of the Galileo series is largely due to the protagonist Yukawa Manabu's role in solving impenetrable mysteries, focusing on the 'how' rather than the motives or backgrounds of the cases. Yukawa, a university professor and physicist rather than a police officer or detective, reluctantly gets involved in the case at the request of his college friend, Detective Kusunagi. He must solve problems through reports and circumstances rather than field investigations, yet he consistently unravels difficult puzzles with his unique coolness and brilliance. Although he seems to have little interest in the motives behind crimes or their resolutions due to his fastidious and stubborn nature, he is willing to lend a hand when he is needed. "The Transparent Spiral" retains the structure and strengths of previous works while revealing Yukawa's past and secrets, deeply portraying his human side. Yukawa's line, "You know nothing about me," may be what the author wanted to convey to the readers. The translator Kim Sun-young stated that "The Transparent Spiral" is a work that "finally discovers the human 'Yukawa Manabu,'" establishing a unique presence. Yukawa Manabu, who has steadfastly maintained his perspective and logic over the years. I am confident that this book will deepen readers' love for him even more. ◆ Special project for the first time in the series Includes the short story "Overlap" The special project short story "Overlap" is also unmissable. This is the first time that a long and short story are intertwined in the Galileo series. It depicts the story following the major incident encountered in "The Transparent Spiral." It will be a special gift for all readers who are reluctant to close the book. ■ Warm tributes from Japanese readers ★★★★★ A work that can only be written by Keigo Higashino. ★★★★★ Contains the secret of the human Galileo, and more. ★★★★★ Can it be read so smoothly? ★★★★★ I never expected to shed tears while reading the Galileo series. ★★★★★ The maturity of the novel and the sharpness of the short story are both present. ★★★★★ I realized that only Yukawa Manabu could have done this at the end. ★★★★★ The Galileo who resurrected from "the house where I died long ago."
