ゼロの焦点 (Zero Focus) is a mystery novel by Seichi Matsumoto, interesting enough, but not great.
Teiko marries Kenichi Uhara, who works for an advertising agency, through a 見合い (arranged marriage) and start living together. She is 26, he 36. Before marrying he worked between Tokyo and Kanazawa, in the North of Japan. For their honeymoon, she wanted to go to Kanazawa and she the environment in which her husband worked, but he decided, to her disappointment, they should go somewhere else. During that trip, she feels he loves her but that, at the same time, is comparing her to another woman. But of course, he is 36, so it's normal he had a previous relationship.
When they come back, he asks for a permanent post in Tokyo, and his requirement is accepted. But before settling in Tokyo, he has to go North with the new manager, Honda, to finish some business and teaching him everything necessary.
And he disappears.
Teiko decides to go to Kanazawa after a couple of days, where she teams up with Honda and search for Uhara around town. From here on we have quite the straight mystery, with lots of talking, surprising plot developments, etc. etc.
Matsumoto's writing style is not bad, but the novel is just talk talk talk, with not much deep in it. You may have 20, 30 pages of meaningless conversation, and he has the bad habit of repeating the information every chapter. Of course, this novel was serialized in a magazine, but still, it makes the novel repetitive. Teiko, and every other character, keep going around the same idea for pages, and you will be feeling the novel should have been trimmed, at least, one third.
On the other hand it is interesting to read about the post-war Japan, how people saw the new situation, and how Matsumoto uses the new society that was coming up for his plot developments. And the atmosphere, the mood of the novel is quite good too. But this doesn't save a cheap mystery and lots of filling.
