After some questioning, Karasawa and Officer Takagi left the Katori family.

After running around for a whole morning, it's now time for lunch.

The two drove back to the Metropolitan Police Department first, took the fur off the coat at the entrance of Mrs. Matsushita's house, and handed it to the Forensic Science Division for testing, and then went to the cafeteria to eat.

Although the testing also requires patience and a period of time, after all, they are not the only one to teach forensic science courses, and there are physical evidences from other cases that need to be tested. In addition, the testing also takes some time, so we can only wait patiently.

Fortunately, the two were not in a hurry. After lunch, they went back to rest for a while.

These "physical evidences" were collected secretly by Tang Ze without consulting their owners. After all, he didn't want to make things look so ugly as soon as he entered the house.

If you ask the other party whether you can collect evidence, it means you are clearly saying "I suspect you are the criminal". It is strange that they will not be happy with you. After collecting the evidence, they will probably kick you out, not to mention the subsequent questioning.

So although these "physical evidence" have no legal effect and cannot be used as evidence to identify the criminal, Tang Ze just wants to confirm it.

If there really is something made of the same material as the deceased, then Tang Ze can directly apply for a search warrant, collect evidence openly, and then wait to arrest the person.

After all, no one can calmly assist the police in solving a case after being suspected of being a suspect. The other party may miss out on important evidence.

Therefore, in order to solve cases, criminals often enjoy secretly collecting evidence even though they know it is useless, because it can reduce conflicts with "important reference persons."

As is common in TV dramas, criminals carefully keep their business cards in handkerchiefs when exchanging them, or use cups that have been used by the other party. These are all examples of this trick.

Even when encountering "big shots" in society, such secret investigations can avoid pressure from the other party and bring unnecessary trouble to your investigation.

After a short lunch break, the two of them set out again.

The afternoon was filled with purposeful running around and visiting. After learning from Mrs. Katori about the deceased's greedy behavior during his lifetime, Officers Karasawa and Takagi visited the other two wives.

When they met alone, they finally told Tang Ze and the other what they knew.

As expected, they all knew about Mrs. Mitori's situation. Later, based on their memories, Tang Ze made a count of how many items Mrs. Mitori had taken from Mrs. Matsushita.

Thanks to this, the two have now confirmed a fact, that is, the deceased was indeed an extremely greedy guy.

There were almost ten items that the three of them remembered alone. They took so many!

In this situation, let alone ordinary friendships, except for your wife, parents or lover, even relatives generally won’t give you so many things!

And I heard that it was Mrs. Mitori who asked for it shamelessly, and Mrs. Matsushita was really good-tempered and gave it to her.

This situation really made people feel that something was wrong. Even Takagi, a good-tempered old man, looked at the dozen or so items on the notebook and couldn't help muttering, "It's a pity that Mrs. Matsushita can endure this."

This transition of demands did indeed lead to Tang Ze and his partner being confronted for the first time by a suspect with a motive for murder - Mrs. Matsushita.

Anyone would feel dissatisfied when faced with such a greedy person who demands too much.

Not to mention that when he asked for it, he looked sarcastic.

And there was another place that made Tang Ze feel strange.

Looking at it from another perspective, Mrs. Mitori's greedy demands have never stopped, proving that Mrs. Matsushita has never stopped this behavior.

On the other hand, Mrs. Matsushita's "giving" is also excessive.

After summarizing this information, the entire afternoon passed.

As for any other important clues or major discoveries, there were none at all. The two of them spent most of their time on the road, but this was also necessary.

To confirm a piece of evidence, one needs to be down-to-earth and make a concrete confirmation. The afternoon visit was a supplement and confirmation of Mrs. Katori's testimony.

Early the next morning.

Tang Ze and the other person came to the forensic class and bought breakfast as usual and brought it over.

"Oh, thank you so much for breakfast. Here is the test report you asked for." Deng Mi handed the document to Tang Ze.

"It seems that there is no gray rat hair in it." After taking it, Tang Ze found that the hair on the three sets of clothes collected yesterday was of a different material from the hair that fell from the deceased's body.

"Thank you, Uncle Dengmi. We'll leave first." Tang Ze had already considered this result, so he was not too disappointed. After seeing it, he planned to say goodbye and leave.

"Ah, wait." At this moment, Tomi, who was eating breakfast nearby, called out to Tang Ze and the other man, turned around and handed them two bags of coffee from the desk drawer. "You always treat me to breakfast when you come here. This is my return gift."

"Thank you very much. I'm really sorry for your trouble." Tang Ze expressed his gratitude.

"No, no, it's my wife."

Deng Mi, who was eating breakfast, waved his hand and said, "A few times when I went back, I told her that you treated me to breakfast and that there was no need for her to prepare breakfast. After she knew it, she asked me to prepare this as a return gift for you.

In my wife's words, this kind of interpersonal communication is also something that needs to be taken seriously. It is right for both parties to interact with each other.

After all, I always eat the breakfast you bring me. I can't enjoy it without showing any gratitude. But I don't understand these. My wife helps me make it.

In my wife's words, I'm a blockhead, a typical science guy."

Although they said so, anyone could see the happiness and full of showing off on the other person's face.

"I see…"

Tang Ze did not eat dog food because of Deng Mi's "show of affection". Instead, the other party's words reminded Tang Ze that "the one who receives thinks more than the one who gives."

"Thank you, Uncle Tomi. We'll be leaving first."

After Tang Ze finished speaking, he pulled Officer Takagi straight out of the forensic class. He couldn't wait to verify what he was thinking.

…

When they arrived at Mrs. Matsushita's house again, Tang Ze and his companions had just gotten out of the car when they saw Mrs. Matsushita just going out.

"Mr. Criminal..."

Seeing the two people appear again, Mrs. Matsushita asked with some confusion: "What's going on?"

"Thank you very much for your cooperation yesterday. I came here today to ask you a few questions." Tang Ze smiled and said, "But it seems that you are going out?"

"Well, my daughter's piano class is about to finish, I'm going to pick her up."

"Then, can we go together?" Tang Ze made this somewhat abrupt request politely with a smile on his face, without any embarrassment.

"ha?"
