After listening to the fairy tale roughly told by Miwako Sato, this idea flashed through Karasawa's mind and he blurted it out.
The first time I put myself in Mrs. Matsushita's shoes was from the perspective of Mrs. Matsushita. It was incredible that she could tolerate a greedy and demanding person.
So naturally, the only candidate with the motive for murder became the key investigation target of Tang Ze and the others.
At the beginning, the direction of their investigation was Mrs. Matsushita to see if there was anything in the other party's hands.
Mrs. Santiao's constant greedy demands aroused the other party's murderous intention.
But as they investigated, Karasawa gradually discovered some "abnormalities" about Mrs. Matsushita.
Just like a mental illness like obsessive-compulsive disorder (Note 1), Mrs. Matsushita's inability to refuse what the other party wants seems to be a symptom similar to obsessive-compulsive disorder.
In fact, Tangze can almost understand the other party. He also had obsessive-compulsive disorder about light switches in his previous life.
And there is a reason why he has obsessive-compulsive disorder about light switches.
The original cause was that Karasawa failed to press the switch properly one day and the light switch got stuck in the middle.
Then the light flashes back and forth between "on" and "off" states.
The result, of course, was that the light bulb burned out.
Although his parents said that after the light bulb broke, it would break naturally over time, but from then on, Karasawa often had to click a few more times every time he turned off the light.
As time goes by, it gradually becomes serious, requiring you to tap the switch many times.
Although after traveling through time, this problem no longer existed for some unknown reason, he still understood this psychology very well.
According to his guess, Mrs. Matsushita may have experienced certain things, which is why she has developed the "alternative obsessive-compulsive disorder" of giving things to others when asked for them.
What happened to her daughter in the piano class downstairs before May, as well as May's words when she asked Tang Ze to help keep her hat, also truly prove this point.
But such anomalies actually weakened the opponent's murderous intent.
Because obsessive-compulsive disorder is such a painful disease, you know it is wrong, but you still can't help but do it.
Mrs. Matsushita may be dissatisfied with Sanae Sanae's demands, but she knows that part of the reason is because of herself.
Instead of having the courage to kill someone, she could just end it by falling out with the other person. The conflict between the two was not enough for Mrs. Matsushita to take the risk and kill someone.
Maybe the other party is waiting for her husband to come back. Presumably the other husband also knows about the wife's problems. Maybe Mrs. Matsushita is just temporarily patient.
When the husband comes back, whether he comes out to warn Sanae Sanatori not to come to her house again, or directly takes his wife and daughter to the embassy to escape abroad, he can stop all this.
Therefore, Karasawa felt that there were other factors influencing it, at least to intensify the conflict and make Mrs. Matsushita "impulsively kill".
I was confused by Mrs. Matsushita's "abnormal" question before, so when I put myself in someone else's shoes, Karasawa always thought from the other person's perspective.
But now, after more than half of this doubt was solved, he suddenly realized that he did not seem to be looking at the problem from Mrs. Santori's position.
Just like the prince in the fairy tale who gives gold coins to the poor, he will be grateful by the poor as a matter of course.
But what if the "poor people" who accepted it didn't get "happiness" as the prince thought?
We always habitually stand on the higher side, unilaterally thinking that it is like the title of the fairy tale "The Happy Prince", a happy story.
But what if the person receiving the charity actually feels "humiliation" instead of "thank you"?
"What will the person to whom it is given think?"
Hearing Tang Ze's words, the three of them looked at each other. They had never thought about this problem, everything just went so smoothly.
But after thinking carefully about Tang Ze's words, I couldn't help but understand the meaning of Tang Ze's words.
"Karasawa-san, are you saying that Sanae Sanae is actually dissatisfied with Mrs. Matsushita's gift of items to her?"
After all, Takagi was Tang Ze's partner in investigating the case, and he quickly clarified his thoughts and understood the meaning of Tang Ze's words.
"Well, during our investigation, Mrs. Mitori probably got a lot of things from Mrs. Matsushita, including even expensive items like necklaces."
Karasawa touched his chin and said, "But how did Mrs. Mitori handle these items that Mrs. Matsushita asked for?"
"Well... I think most people will keep it safe, right?" Yumi Miyamoto interjected: "After all, it was something she shamelessly asked for."
"In that home?" The messy room flashed through Tang Ze's mind, and he couldn't help but frown, "The minds of both the giving party and the receiving party are in a fog."
"Ah...well..." Takagi smiled bitterly. From the meaning of Karasawa's words, it was self-evident that the two of them were working this afternoon.
Although Mrs. Matsushita knew about the "abnormality" of the other party, her psychology was still unclear, and there was no way of knowing what Mrs. Mitori thought.
Karasawa is currently unable to determine whether Mrs. Matsushita is the murderer. Judging from the current situation, the other party does have this motive, but it is only a motive.
At this moment, the investigation has reached a bottleneck. Now that there are other ideas and clues, Tang Ze can only follow this clue to continue to delve deeper, even if it is troublesome.
There may be gains later, but it may also be nothing, but it is better than being unable to do anything.
After finishing the meal, Takagi, who seemed to have recovered from the "love", felt the countless murderous eyes around him, and pulled Tangze to escape from the cafeteria in embarrassment.
Arriving at the office, Takagi breathed a sigh of relief, "What should we do next? It's lunch time, so it's not a good time to visit..."
However, after waiting for a long time, Takagi did not receive a reply from Tang Ze.
When he turned to look at Tang Ze, he found that Tang Ze was holding the hat given to him by May and looking at something intently...
……….
After the lunch break, the two of them drove all the way to the Santori family's home in Qiu.
The male owner of the Santori family is not at home at the moment. After all, it is such a drastic change that his wife was murdered at home. Even if the body cannot be retrieved for the funeral for the time being due to the case, he still needs to contact his mother's family.
When the two contacted each other, Mitori Shuji was at his father-in-law's house discussing matters such as the future funeral.
Fortunately, a cordon was set up outside the house, and there were police officers standing guard outside the door, so the two of them successfully entered the room after showing their IDs.
But it became very embarrassing after that. When he came to the crime scene again, the messy room in front of him still made Tang Ze frown.
It feels like it will take a lot of time.
ps: Obsessive-compulsive disorder is a psychiatric disorder rather than a mental illness in medical classification.
