"I don't know. "Of course, Masuo knows what he will see if he lets Matsuda enter the hall. So what he said was extraordinary, and he had no confidence.

The downed bookshelf was pressed right on his wife, Kayo Masao, who would have a knife stuck in her back, yes, in the middle of her back. Masuwei was very sure, because he had already experimented all night last night, and he had to adjust dozens of times before he could be sure.

Before he could step into the hall to clean it up, he let the policeman named Matsuda completely destroy it. The bookshelves are overturned, which can be explained, but the coils that are wound around the spinning bike have not been recovered. In this way, the carefully planned alibi is completely invalid, and instead becomes the most powerful evidence that he is the murderer.

"Matsuda, what's going on?" Sato and Conan walked into the hall. Of course, Sato didn't forget that the depressed Masuo was still at the door.

"Masuo Kayo has stopped breathing. Matsuda half-crouched next to Masuo Kadai's body, pointing to the bookcase pressed against her back and the spinning bike next to her: "It's clear that someone took advantage of the deceased's habit of moving at a certain time to cleverly set up the crime scene, and then ran elsewhere to do an alibi." And is this alibi more convincing than being in the Metropolitan Police Department, with us criminal police officers in charge of criminal cases? ”

"I, I" Katsura Masuo, who was at the door, opened his mouth several times without saying a word.

"Can't tell, do you need me to help you say it. "Matsuda stood up and pointed to the wall Last night, you designed a simple mechanism there, aiming a knife at the position of the spinning bike, and then using a wire to connect the bookcase to the axle of the pedals, so that whoever rides the spinning bike will be stuck in the back by the knife that fell down. In order not to deviate the position of the bookcase, you also have the bookcase next to it full of books. After saying that, Matsuda pulled the smaller bookcase next to him, and it was full of books to prevent the large bookcase from falling outside.

"I don't know the way, I don't know anything!" Massuo shook his head in horror, making a pointless resistance.

"It doesn't matter if you want to answer or not. Matsuda chuckled, "But don't underestimate us as police officers." As he spoke, he used his white-gloved right hand to weigh the coils on the spinning bike: "The murder weapon is a thing, and there is really no way to find it if it is hidden, but once it is exposed under our noses, we can even find out who bought it at what time and where." Even which manufacturer made it, after several people resold it, there are traces. ”

Zengwei's lips trembled, and he tried to speak several times, but he couldn't make a sound. He wanted to say that the police would not have evidence to prove that he had designed this mechanism, but Matsuda was frightened by the first step. What if I find out?

"What do you want to say?" Matsuda looked at Masuo's expression with interest and continued to put pressure on him: "You have to know one thing clearly, if you say it yourself now, you will turn yourself in, and if we find out, the nature will be different." ”

"This, I" hesitated for a long time, gritted his teeth, and played a scoundrel with the mentality of breaking the can: "That's right, I bought the coil, but it was used to tie things, how did it become like this, I don't know how it happened." If you talk to me like this, do you have to decide that I am the murderer!? Then come up with evidence!

"Yo?" Matsuda raised his eyebrows: "It's really arrogant." It's useless to yell at me for this kind of thing, so let's wait and see. But you have to know one thing, we are professionals, and the murderers, I'm afraid that few of them have received professional training, right? There will definitely be traces left in the places where they don't know the way. ”

"Mr. Masao, you have to remember one thing, as long as you pass by, you will definitely leave a trace. After Matsuda finished speaking, he stopped looking at Masuo: "We are going to conduct the necessary search of this house, please cooperate with us." ”

Subsequently, the forensic division soon came to the scene, and when the investigation and evidence collection were carried out, the search team had already blocked the scene and carried out inter-regional investigations.

Now that there is a clear goal, then things are simple, just search carefully around his range of activities. Of course, this kind of thing is a delicate job, and professional personnel are responsible for it.

Soon, Matsuda got his hands on a photo album with several photos of people circled with watercolor pencils. Several photos are like this, but there are only two people in the circle, and after carefully identifying the figures of the two people, Matsuda "snapped" his hands and closed the album, and a light flashed in his eyes.

"Sato, immediately detain Katsura Masuo and detain him for 24 hours. Matsuda said and handed the album to Sato: "I'll come and see him, and you'll be in charge of investigating the two people in the photo, and you can bring them back if necessary." Pay attention to safety, they are most likely robbers who robbed the bank the other day, armed with firearms. If you are able to recover the stolen money within 24 hours, then it is time for Masutail to give up resistance. ”

"I'll get in touch with the police. Sato glanced at Matsuda: "Aren't you going? That's a big case that attracts attention." ”

"Hey. Matsuda pouted: "It's a big case in the eyes of those leaders." In my eyes, what is a matter of human life is more important. ”

"Mr. Masao, please come back to the Metropolitan Police Department with us to assist in the investigation. After Matsuda finished speaking, he walked up to Masuo: "Of course, you also have the right to refuse, but we will enforce it, it's four o'clock in the afternoon, and we still have twenty-four hours to get to know each other more deeply." ”

Masuo didn't say anything, and now of course he can't say anything, but to exercise his right to keep silent.

Taken to the interrogation room of the Metropolitan Police Department's search section, he sat quietly and Matsuda began to stare wide-eyed.

It wasn't until Matsuda got the on-site investigation report sent by the forensic class and read it carefully that Matsuda began to speak: "The results of the investigation are out, and there are only two traces left in the entire house, one is your wife, and the other is you, Mr. Masao." ”

"The results of the investigation show that there are no intruders, yes, in your home, except for us police officers and Conan's little child, the forensic division has not found any footprints, fingerprints, or dander left. Can you tell me what this is for?" Matsuda tried to find a breakthrough, and if Masuo had been silent for so long, then he would have to find direct evidence to prove his crimes.

"Only the fingerprints of you and your wife were found on the bookcase that was used as a killing agency. Matsuda babbled and said, "If the murderer of the design agency is an outsider, then he will definitely wipe off your fingerprints when he cleans up the traces left by himself, which means that the surface of the bookcase should be clean, and no one's fingerprints exist." Could it be that your wife designed that mechanism herself?"

"Mr. Masao, you can not speak, but now there is more and more evidence against you. Saying that, Matsuda flipped to the next page of the investigation report: "There are many dents on the bookcase caused by collisions, and there are also paint peeling on the surface of spinning bikes, and the forensic class has concluded that there are so many dents caused by multiple collisions. Is this an experiment on the accuracy of the mechanism? Who else can do this in your home multiple times?"

"Just because you're carrying it so hard now doesn't mean you can get away with it, and it seems to me that you're completely challenging us police, as well as future prosecutors, judges, juries, etc. You're challenging our IQ limits. ”

Masuo was said by Matsuda, and licked his lips that were a little chapped: "I, I want to drink water." ”

Matsuda, who "snapped", slapped the table and roared violently: "Let's talk about your motive for killing first!" At this time, it was obvious that the tail was shaken, and he was in a time of hesitation.

"I, I didn't want to kill her. Massuwei was frightened, and subconsciously said it.

"Really?" Matsuda smiled smugly, "Didn't you want to kill her?"

After saying a little bit of leakage, the body that increased the tail and strengthened suddenly softened, and sweat soaked on his forehead.

"Can you talk about motivation now?" Matsuda saw that Masuo had given up the strong shell, and it was a good time to strike while the iron was hot.

"Actually, it's for the insurance money. Masuo lowered his head and didn't look into Matsuda's eyes: "I bought a huge amount of insurance money for my wife, and it just so happened that recently she suspected that a bank robber was targeting her, so she wanted to borrow the reason of the bank robber." ”

"Japan's criminal laws have been very light in recent years, and the death penalty is basically uncommon. Matsuda's topic drifted to the criminal law again: "It seems that you are also very concerned about this kind of thing, you bowed your head and admitted your mistake and were sentenced to a few years, but after you came out, you had an extra deposit of 200 million yuan." But, you trust your friends so much?" said he held up two photos, the two people who were circled by Kayo Masuo on the album: "I believe that there will be results over there soon, are you still going to continue lying?"

Seeing the photo, the only remaining force to support his body disappeared and he sat down in a chair.

With a clear goal, the first lesson was still moving quickly, and it only took a few hours to investigate the identities, addresses, and recent activities of those two people. Of course, the fact that they disappeared for a few hours at the time of the bank robbery a few days ago was also investigated. Then the rest is simple, break in, subdue, search.

When the 200 million yuan of stolen money was recovered, Matsuda also got a complete confession from Katsura Masuo. The details of his plan to rob the bank and his murder of his wife, the steps, and the details of the implementation were all confessed, so that the case could be closed.

Massuo Katsurazo, Masao Kadai, this couple and two names entered the world of Matsuda, just like a pebble thrown into the lake, causing a ripple and then disappearing without a trace.

How did a wife who could use the law to coerce her husband for money and a husband who would not hesitate to kill his own wife for money came together?

Husband and wife, husband and wife. Hey, isn't this a family that doesn't enter the door? Matsuda glanced at Masuo's confession in disgust, then put it in the file bag and handed it to Takagi and got up and left. He never wanted to hear and see anything about the couple again.
