The original film and television work of the same name starring Xiao Shenyang and Qin Hailu!
Known as the "God of Short Mysteries", he was once a member of the Mystery Novels Research Society of Kyoto University.
He made his debut in 2004 with "Alphabet Mystery" and was highly praised in the reasoning world for his skillful transcendental logic. The following year, he made his debut on the Best 10 list of basic reasoning. Since then, he has successively published "The Collector of Secrets", "Absolute Alibi" and "The Museum of Trickery", repeatedly sweeping the three major Japanese mystery lists and winning many authoritative mystery awards.
"All Suspects" is a new collection of mystery short stories by Oyama Seiichiro, focusing on multiple reversals. This book tells the story of seven cases centered on the "isolated island model" in the reasoning genre. Since the protagonist has a special ability to improve the reasoning power of others, who the detective is besides the murderer also becomes one of the mysteries, making all the cases even more confusing.
Oyama Seiichiro's works are famous for their "fast pace, zero nonsense, and divine twists." At the same time, they constantly introduce new works, and each new work is climbing to new heights in the field of original reasoning.
Reader comments
The hapless murderer is so funny. It's not okay to be bullied by passengers. If you don't have aura, you won't be able to turn around even if you become a robber, hahaha
The setting of this book is very novel and interesting. The "Watson force" and reasoning competition are very interesting. After the protagonist is kidnapped, he recalls the "Blizzard Villa" case he encountered, which also avoids the problem of "the police in mystery novels are too useless".
Since the setting of the novel itself has a sense of humor and humor, so does the style of the entire book, with all kinds of Japanese complaints and Japanese humor emerging one after another. Some readers may find this awkward or slow-paced, but I personally enjoyed it.
The biggest feeling after reading it is: Why is there no 2?
After reading it, I really felt that the reasoning was not particularly reliable, but the comedy was definitely serious, especially in the bus chapter. The driver said: I don't know why, I just want to reason. I had a lot of fun reading it. I felt that this book was more funny than reasoning [face-covering] [face-covering] [face-covering]
Another time when I was on a business trip and had nothing to do, I was browsing TV to see what movies were available, and found that there was a movie in Xiao Shenyang that was a remake of the first story of all the suspects [face covering] [face covering]
It's such an interesting case study, with some funny elements. I couldn't stand it when Watson's force came out. I just pushed it without logic. But after watching it, I realized that it's not metaphysics, it's similar to super powers. The new generation's imagination is quite big.
Watson Li really laughed every time I listened to it, it was so funny hahahahahaha [crying with laughter] Seven or eight cases were crammed into such a short space. Although everyone can more or less crack these familiar crime methods in 2025, it is quite interesting to look at them together. Especially every time someone will say "I also want to reason" [I also want to try to reason], there is always an inexplicable sense of joy hahahaha
The story of this book is fast-paced, not sloppy, and has constant twists and turns, which surprised me very much! I particularly like the author's portrayal of characters, such as Yami, who has sharp eyes. Her character is very distinct. Moreover, the writing style in the book is very delicate, and the description of the environment is also very vivid, which made me feel like I was on that isolated island. It's a bit strange that the boss and his sister are missing. I hope there will be a reasonable explanation later. Looking forward to the movie version!
If you want to watch a slight change of format, you can watch it, because the reasoning content is all original, and it is easy to read, not that scary (thriller), and there is no bitterness or hatred. Because it is a collection of short stories, it will definitely not make the reasoning particularly exciting, but it can definitely make you smile and be amazed. I personally feel that it is still worth watching, and it is much better than the man-eating tree on the dark slope.
After Wado was imprisoned, he recalled the case. The effect of his Watson Force drove the people in the same space with him to start the reasoning mode. Everyone's ideas are wonderful and interesting. Follow them and enjoy the reasoning process. I like this book very much, I like the author very much, and I'm looking forward to the new book (☆∀☆)
It's quite interesting, the protagonist is a real treasure in his own right. The title of the book reflects the content, and the writing method is quite novel. It is worth reading [Thinking] [Like]
The content is on the light side, and even the murders are not scary or bloody. Suitable for everyday light reasoning enthusiasts. The superpowers in the article are not as disgusting as ordinary golden fingers. They are settings that add interest to the article. After reading it, you still have more to say.
Watson's power is so terrifying
Personally, I prefer this kind of light-hearted reasoning story.
Overall, it's good. The kidnapper's deduction seems to be flawed, but it would be great if it could be turned into a book.
This is the first time I read a book by this author, and I have to say that it is very interesting.
I just like this kind of fast-paced mystery novels
Humorous and clever narrative, impressive
It's super good. Dashan's short story is very interesting.
Interesting entry point, read in one go
Awesome. So beautiful.
Light novel mystery
Reasoning logic hard core
This book is quite good
It's okay, but my IQ is a little too low. I hope it can be a little higher.
The charm of this style lies in this!
"I don't know why, I just want to reason about it."
It was a bit hard to watch at first, but once you calm down and watch it, it's quite interesting. I'm still not used to some of the writing tone of Japanese novels, but the short mystery is a bit interesting.
I bought this book when it was on sale. The setting is very interesting. I'll give it a second try.
A very enjoyable book, I feel like I have watched another episode of Conan
It's good to watch, constantly overturning and reinventing the wheel, pure reasoning, very interesting~
A very interesting setting - Watson's force, combined with original reasoning. Be prepared to read all the works of this author.
