"Youyi Police Department! Your reasoning is too scary, isn't it? The knife itself flew from behind Mrs. Gardai and killed her? Could it be that this room is haunted? This...... This...... Isn't that incredible? Are we going to find a soul exorcist? I received a business card from some kind of Soul Removal Office before, and I heard that their boss is very famous, do you want to invite him over? ”

After being analyzed by Yuichi like this, Takagi, who instantly felt that this room was a little cold, asked in a low voice after tightening his suit, as if his voice would alarm something strange as soon as his voice was high.

"I'll get rid of you! You've watched too many horror movies, right? Takagi! What I mean by throwing knives to kill people is, don't you think all these clues point to an answer? ”

"What's the answer? Isn't it a ghost? ”

"Of course not! Doesn't it all feel like the victim was alone in the room in the house in the first place? All these clues are just a deliberate set up for us in advance, so that we can believe that there was a second person in this family who was present at the time of Mrs. Gardai's death, in this case! A person's alibi is guaranteed! Are you right? From the very beginning, he continued to provide us with clues and actively cooperated with our Mr. Masuo Katsuzo! ”

"What? You actually doubt me? Youyi Police Department! It's my wife who died! How could I possibly kill Gadai? We've always been very affectionate! Friends around you know it! ”

"Oh? Is it really affectionate? Mr. Masuo! Do loving couples sleep in separate rooms? Even if your family is special! Then I ask you, what color is the quilt that Mrs. Gardai has not sorted out yesterday, and what pattern is on it? Can you tell me? Mr. Masuo! ”

"This ...... I've been under a lot of pressure at work these days, plus the bank has been robbed, where can I be in the mood to pay attention to these! ”

"Oh? Is it? All right! Let's get down to business! Let's talk about the flying killing knife! ”

In the face of Katsura Masuo, who is already sweating profusely and still holding on, Yuichi, who has already established himself invincible with his photo album, doesn't mind having a reasoning show like his cousin who loves to pretend to beep, and play with those criminals who are like lambs to the slaughter, especially this kind of bastard who can even do it with his own wife.

Forcing criminals to death without reasoning? Then I'll crush him to death with evidence!

Pouting disdainfully, he walked over to the bookcase that Shiratori had just discovered, and Yuichi looked at the dark beige curtain and smiled.

"Did you notice the top of this cabinet? You can come and take a closer look! There are strange blood stains on it! ”

"Oh really! There really is blood! ”

"And then look at the bookcase, don't you think it's a great design?"

"Huh? Youyi Police Department! What do you mean? Where's the design? ”

"Murder! If you had to fix the knife on the top of this dark beige bookcase, because the bookcase next to it was full of books, as long as it fell down by external force! If you can't flip to one side, you can only flip in one direction! ”

"Exercise bike!" Following Yuichi's prompt, after visually measuring the height of the cabinet, Sato, who had modeled and demonstrated it in his mind, couldn't help but exclaim.

"That's right! Quite a coincidence, isn't it? As long as the cabinet and the exercise bike are fixed together with a sturdy fishing line, Zoo Kayo, who basically steps on the exercise bike every day, will send the knife fixed to the cabinet to his back. ”

"This is how throwing knives kill people?"

"That's right! The threads I just found in the pedals of the exercise bike also confirmed my hypothesis! And I also found this interesting circle at the head of the line, I don't think most people will play this circle at the head of the line, right? ”

"Interesting reasoning! But by tying the cabinet to the exercise bike through the line, will Mrs. Masaki Kadai who rides the bike not feel it? The pedals are going to get heavier when she's riding, right? ”

"Huh? Don't you know that the burden on exercise bikes is slowly increasing? The deceased probably wouldn't have noticed it because it had always been like this! ”

"But when you found the body, the bookcase didn't fall down, did it? If you really want to devise such a complex trick, you might as well hide and wait for the opportunity to do it! Shiratori, who was obviously a little unwilling, couldn't help but get angry again after Sato explained it to Yuichi, but as soon as the words came out, he couldn't help but lock his eyes on Katsura Masuo.

"That's right! There is only one person who needs to do this, and can do so, and that is the husband of the deceased who knows the furnishings and habits of the deceased best, and who is also the first to enter the room...... Mr. Katsuzo Masao! You assigned Takagi and them to the second floor as soon as they came in, just to deal with the aftermath, right? ”

"Please! No kidding, Officer Yuichi! What if there were a lot of police officers coming here today, or if someone came to the living room before me? How do I have time to set these up? ”

"Hah! Just fill the top of your bookcase with books! This can not only squeeze the knife, but also disguise yourself as a gangster when the police come in and fight with Mrs. Gardai is messy! It's not like that's unexplainable to you, is it? ”

"But ......"

"Report! Kudo Police! The guy you asked us to find has been found! As soon as he was caught in the police car, he was so frightened that he confessed directly! The robbery of the cup bank was directed and acted by him and the president, Mr. Katsura Massuo! ”

"Hah! It seems that Mrs. Masuo Kadai still has her intentions in enclosing the two of you, right? Mr. Masuo Katsuzo, do you want to continue to resist stubbornly? ”

Just as Katsura Masuo was about to explain something, a policeman with an excited face ran in to report the situation, completely breaking his disguise. After his bones seemed to have been drained, Katsura Masuo couldn't help but cry after he collapsed on the ground.

"I can't help it! It's all this woman forcing me! In order to bear her expenses and maintain the operation of the family, I couldn't help but embezzle the funds in the bank because of the insufficient salary, but the headquarters of Dongdu Bank was about to come down to check the accounts, and I had no choice but to team up with my friends to create a robbery case to smooth out the empty accounts! Unexpectedly, Gadai, who agreed to act together, actually became greedy for the 200 million yen when he returned home, and threatened me to give her a large part of it, otherwise he would report and expose me! It is I who said that the embezzlement of bank funds and the robbery of banks anyway! She doesn't have to go to jail! I couldn't help but kill her when I heard her say this, I gave everything for this family and her, but it was best for her to treat me like this, do you think she shouldn't die? Yes? Doesn't she deserve to die? ”

Listening to the hoarse sorrow of Masuo Katsurao, Yuichi and they looked back at Masuo Kayo lying on the ground when they were obviously in a mood again, but unfortunately if they made a mistake, they had to pay for their mistakes, Masuo Kashiro used his life to erase her mistakes, and Masuo Katsura couldn't escape prison. The cause of everything is greed!
