This is a new mystery set in Gunma Prefecture, Japan!

The Ligan police station in Gunma Prefecture received a report of an accident, and when investigators arrived at the ski resort where the incident occurred, they found the body of a man who had bled to death from a stab to the carotid artery. The killer was almost certainly the man who was in distress with the victim, but investigators did not find the murder weapon. The location of the murder was below the cliff, and the snow around the killer and victims was not trampled, so the killer could not have disposed of the murder weapon. So, what did the killer stab him to death with? (Off the Cliff)

Investigators found a right upper arm in the "Xuan grass corridor" at the foot of Zhenming Mountain, and concluded that this was a case of dumping the body. If the killer was just hiding the body, he wouldn't have left his right upper arm in such a prominent position on the promenade. Why would the killer dismember the body? (The Grace of Life)

There's been a series of arson attacks in residential areas of Ota City. County police Officer Gerban is assigned to the investigation, but before he can locate the suspect, the crime stops abruptly. What is the criminal's motive for the crime? Why did you stop setting fires again? The investigation seems to be at an impasse... (Combustibles)

This book will look for the "invisible common ground" of successive arson cases as the theme, connecting five wonderful mystery stories of Ge police Department.

Honobu Yonezawa

He was born in 1978 in the Gifu Prefecture. From as young as he could remember, Yonezawa wanted to be a writer. At 11 years old, he wrote a sequel to H. G. Wells's The War of the Worlds,and started writing original novels in the second year of junior high school. In his second year of Kanazawa University studying literature, he started publishing his works on his site Hanmuden (the website was temporarily shut down after his official debut and these works are currently unavailable[4]). His early work were diverse in genre, but Yonezawa was struck when he read Kaoru Kitamura's Flying Horse and Princess in Rokunomiyawhile in university, and decided to turn his attention to writing mysteries.

After graduating from university, Yonezawa convinced his parents to let him try and attain his dream of writing a novel for two years. He got a job as a bookstore clerk in Takayama while he continued writing on the side. In 2001, he officially debuted with the novel Hyōka, which received an honorable mention in the 5th Kadokawa Gakuen Novel Young Person Mystery and Horror Category Awards. His decision to submit was fueled by positive reception of Hyōka on his website Hanmuden,that he personally saw a future in the combination of light novels and mysteries,and because he was late for the deadline of another award. Hyōka became the first novel in a series dubbed the Classic Literature Club series, to be distributed by the newly established Sneaker Mystery Club within the Kadokawa Sneaker Bunko imprint. Hyōka was soon followed with Gusha no Endorōru in 2002.

However, when Yonezawa had completed the draft for the third and what he intended to be the final book in the Classic Literature Club series, the label was going on hiatus due to changing trends in the market, so he could not get it published. Despite this, he was approached by Tokyo Sogensha who inquired what he was working on, thanks partly to recommendations from writers Kiyoshi Kasai and Kazuki Sakuraba.[9] When he explained the situation to the publisher, they asked to see the draft and after a few days they requested rights to publish it. After discussions between Kadokawa, Tokyo Sogensha and Yonezawa, they agreed to have the novel published, and after changing details such as the characters and the setting, Sayonara Yōsei was published in 2004. It was featured in the magazine Kono Mystery ga Sugoi! in 2005, ranking 20th in the domestic category.

In the same year, he published Shunki Gentei Ichigo Taruto Jiken , the first novel of the Shōshimin series. Around the same time, he moved from Gifu to Tōkyō.

In 2008, when Yonezawa published Hakanai Hitsuji tachi no Shukuen , he states that he started not only paying attention to the riddles present within his works, but also how they appeal to a wider audience. So when he published Oreta Ryūkotsu in 2010, which incorporated some fantasy elements to an otherwise classical mystery story, it won the 64th Mystery Writers of Japan Award for the following year.

In 2012, Kyoto Animation aired an anime adaptation of the Classic Literature Club series under the name of the first novel, Hyōka.

Since 2013, he has been on the selection committee for the Mysteries! Rookie of the Year Award .

In 2014, his short story collection Mangan was selected as one of the best mysteries in the Mystery ga Yomitai! , Shūkan Bunshun Mystery Best 10, and Kono Mystery ga Sugoi! It was ranked the top in domestic rankings and became the first book in history to receive three simultaneous rankings from different publications. It also won the 27th Yamamoto Shūgorō Prize and the 151st Naoki Prize.

In 2016, he was selected by literary magazine Granta in their Japanese edition as one of the Granta Best of Young Japanese Novelists.

In 2024, the first two novels of the Shōshimin Series were adapted into an anime produced by Lapin Track, and released under the name Shōshimin: How to Become Ordinary.
