理由

「事件」像磁石般,
把受害人和凶手吸在一起,
事發的「理由」,就藏在那股引力之間……

第120屆直木賞得獎作品、
與《模仿犯》、《火車》並列日本現代推理小說金字塔的傑作!


「有的屋子不能安心住人,來到的住戶原本打算長久定居,卻總是因為某些事情接二連三的冒出來而不得不搬走,二○二五號就是這種屋子。」

東京荒川區的千住北美好新城是一座設計新潮、形象高級的超高層大廈型住宅社區,西棟二十樓的二○二五號卻在大雨之夜爆發了一樁命案──一家四口同時喪生,三人陳屍於屋內,一人墜樓身亡。刑警趕到現場、聯絡親屬認屍,竟發現死者全都不是登記在二○二五號的住戶小糸家成員,而是四名身分不明、彼此毫無血緣關係的男女老少。其他鄰居曾在日常生活中和他們擦身而過,但渾然不知他們的背景。

真正的屋主小糸夫婦身在何方?原本應該管理妥善、門禁森嚴的豪華社區,為什麼能夠神不知鬼不覺地住進一群陌生人?

曾經也是千住北美好新城準住戶的中年男子石田直澄,在二○二五號大門內側留有指紋,案發之後便行蹤不明,警方和媒體都視他為頭號嫌犯。經過四個月的逃亡生活,他終於主動投案,因為他的現身,「荒川一家四口命案」的謎底與黑幕即將露出曙光──

命案為什麼發生?從社會上不同角落聚集到這戶住宅裡、又共同遭逢死亡的四個人究竟是「誰」?「誰」又是凶手?命案之前發生了什麼?之後又留下了什麼?

「宮部的推理小說,的確極清楚的從當下日本社會現實著眼,寫的是日本宛如太平盛世當前社會底下流漾的不安和隨時可能爆發的暴戾。但做為一個後來的、基本社會問題已被寫盡的社會派推理作家,宮部並未被逼往更幽黯更乖戾、更人性邊界、更心理概念的宿命方向走,她奇特的回轉到更平實的家常世界來。」
──唐諾(摘自推薦序《平成國民作家宮部美幸》)

This is definitely a social critique more than anything else. Part of it felt too encyclopaedic and it disrupts the narrative. But overall impressive to see the author connecting so many different dots together. The ending feels somewhat underwhelming, but the I figure the point is not to solve a murder mystery but to expose the various social issues. Ultimately it's about the different meanings of family and cohabitation, and how each person navigates them.

I got about half way and got bored. It started out interesting with a murder case, but then it just went on and on about so much details. Reminiscent of how Stephen King has so much details. Feels like she could have written this in about 1/4 the length.

故事算蠻流暢的,挺好看。
不過角色很多,容易忘記名字跟之間的關係,哈!

This book was amazing. This book, Riyu (which means, the reason) a mystery book by Miyuki Miyabe. This book concentrates on about 5 different family, each having their own trouble. The story is told through an interview. Telling a story about how the 5 different dead bodies each not having any connections to each other, ended up in a new modern apartment. It was amazing how the author connects the five completely different family. And I will like to recommend this to all mystery lovers.

The book is not a traditional detective fiction. Rather than intensively discovering the murderer, It depicted the life related to the terrible murder and thus triggered thoughts about family and self. The language can be plain sometimes, but it pertinently reveals people's struggle and common problems.

 家族とか、死ぬこととか、現代の日本の社会状況とか、いろいろと考えさせられた。ミステリーとしてのおもしろさは、もうひとつ。

在最後, 小系弘思想問"我也會殺死阿姨他們嗎?"
作者說有一天一般人都知道這個答案時期會來臨
而此時, 八代就可以瞑目了...

完全不瞭解為什麼有一天一般人都會知道
是表示答案是肯定的, 社會上的悲劇一再重演?
但這跟八代瞑不瞑目有什麼關係?

和先前第三人稱觀點(有一個人一直辦案)不同,這篇除了綾子家以外,都是用一個報導文學的口吻在寫,相當特別,而故事取材自相當貼近生活的法拍屋。雖然法拍屋是表面的故事,但看完整本之後會發現其實這本書在寫不同的家庭的故事,而且作者還寫了很多不同的家庭互相對照。婆媳之間、親子之間、姊弟之間都有好幾組,有血緣是不是家庭?沒血緣是不是家庭?

“無處可去和無處可回,這和自由完全是兩回事。”

“現在的年輕人都有八代佑司這種心理,認為父母只是方便的金主,是和自己住在一起的用人。年輕人能理解八代佑司的心情吧”

“所以,如果我一直和阿姨住下去,長大以後覺得阿姨他們妨礙了我時,也會殺了他們嗎?”

我明白作者想要通过这本书表达的社会问题很多,但结构太臃肿,而每一个方面又不能像手术刀一样精确的切开,写透。结果就造成拖拖拉拉的剧情,失去紧凑和精彩感。

ฆาตกรรมหมู่ยกครัว ไม่ได้ให้น้ำหนักที่ตัวคดีมากนัก แต่มุ่งตีแผ่ชีวิตของผู้เกี่ยวข้องอย่างมีมิติและลุ่มลึก จนเหมือนยำรวมมิตรปัญหาสังคมนิยมวัตถุ เทคนิครีพอร์ทเทจทำเราเกือบจมข้อมูล ชอบการสร้างเลือดเนื้อให้ตัวละครภายใต้ความคิดที่ว่า คนๆ หนึ่งจะมีตัวตนขึ้นมาก็ต่อเมื่อมีอดีต เติบโตมาอย่างไร กับใคร ฯลฯ
