"Eh?"

Shiratori and Takagi couldn't help but look at Miwako in confusion.

Miwako walked to the bookshelf next to Baidi with her long jade legs. Her beautiful eyes narrowed slightly and she said to the two of them,

"If the murderer is on the top floor of the bookshelf, fixes the knife with tape or something, and then ties the end of the kite string to the axle wheel of the bicycle, as long as the victim keeps pedaling the bicycle, the string will slow down. Scroll slowly, and finally the bookshelf falls down. In this way, the knife can automatically penetrate into the victim's back."

"Eh?"

Hearing Miwako's reasoning, Shiratori and the three of them couldn't help but be very surprised.

But only Miwako glanced at Baidi next to him after finishing speaking, wanting to see Baidi's reaction, but Baidi's reaction But it was completely different from what she expected. His expression looked very calm, with a faint gentle smile.

"This idea is indeed interesting, but will it really go so smoothly?"

White Bird couldn't help but asked,

"Isn't the other section connected to the bookshelf?"

"No," Takagi next to him thought for a while and couldn't help but said,"Officer Shiratori, the possibility of what Officer Sato said is very high, because there is another bookshelf full of books next to the bookshelf inside. So the direction of the fall can basically be determined.

The victim he wanted to murder must be sitting on a bicycle, and the victim just couldn't see the bookshelf falling."

"However, the pedal of the bicycle suddenly became heavier. Even if the victim did not notice it, he would definitely feel something was wrong."

Faced with Shiratori's doubts, Miwako couldn't help but smile lightly, her smile was capable and clean,

"how? Don't you know, the original design of a bicycle like this will slowly increase the load of sportswear. Since the victim is used to riding on it, he will naturally not notice it."

"Then let me ask you," Bai Niaodi still looked confident,

"When you found the body, the bookshelf didn't fall down at all? Besides, instead of running here and making these troublesome designs, it would be more accurate to just ambush her here and kill her."

"wrong!"

The White Emperor next to Miwako suddenly raised his head, looked at the three people in silence in front of him with a faint smile, glanced at Takagi thoughtfully, and then reminded,

"At that time, the first person to enter the crime scene was Mr. Masuo. A few seconds later, after Mr. Masuo screamed, I rushed into the living room, and Miwako and Takagi also rushed in soon after.

When we found the body, the bookshelf did not fall down, but,"

Bai Di looked at Mr. Masuo who was covered in cold sweat with a half-smile.

"After Mr. Masao entered the living room, I was very curious as to whether the bookshelf fell down and why there was no scream immediately."

Hearing this, Mr. Masuo suddenly had a drop of cold sweat on his face. Just as he was about to explain hastily, he was interrupted by Bai Di without hesitation.

"Moreover, the murderer will never do useless things, and the design he makes must have his purpose. However, what would be the purpose of designing such an alibi killing method?"

Hearing Bai Di's words, Miwako's eyes became brighter and brighter. All the clues and doubts in her mind finally became a clear line.

"Alibi!"

Miwako suddenly raised her head, looked at Shiratori and explained,

"The reason why the murderer did this was to create his own alibi. In other words,"

"There is only one person who can push the bookshelf back to its original position," Takagi muttered subconsciously after hearing Miwako's words.

Miwako suddenly turned her head to look at the person present, and said with bright and confident eyes,

"That's right, the murderer who could complete this series of rigorous murder techniques could only be the one who was familiar with the family's routine and the victim's exercise habits, and was even able to enter the house one step earlier than anyone else, the victim's husband, Masuo Katsura. Mr. Zao, you are right, right?"

When he heard Miwako's last words, Mr. Masao was so frightened that he opened his mouth wide and shouted in panic,

"What on earth are you talking about?"

"That's right," Takagi slammed his hand and suddenly realized,

"No wonder you have to call inside the station, because you know very well that your wife rides a bicycle at 2 o'clock in the afternoon every day, so you can roughly estimate the time of the stabbing.

In this way, Mr. Masao, as long as you go to the police station and let her be killed while talking on the phone, you will have the best alibi.

In the middle of the phone call, you suddenly put your hand in my hand just to let me know that the person you were talking to was your wife."

"Moreover, you went to the second floor to look for it as soon as you got home. You probably took advantage of this opportunity to restore the fallen bookshelf, right?"

Miwako couldn't help but raise the corners of her mouth slightly and said to Mr. Masuo

"Please stop joking about this, okay?" Mr. Masuo defended hurriedly,

"If there were really many police officers coming here at that time, some detective would have entered the house before me.

Besides, even if I really fixed the knife to the bookshelf, then shouldn’t the knife still be on the bookshelf now?"

At the end of the sentence, Mr. Masuo hurriedly looked at Shiratori, hoping that Shiratori could defend him.

"So, how about this? Bai Di

, who was standing behind Miwako, suddenly smiled lightly and stuffed a folded paper knife at an unknown time into the top layer of the bookshelf inside. The top layer of the bookshelf was filled with all kinds of things. There was only a narrow gap left between the books and the top cover of the bookshelf, and the paper knife was stuffed in.

"As long as the books are packed tightly on the top shelf of the bookshelf and the knife is inserted into the gap between the books, there is no need to use feet to fix the knife.

If the top of the bookshelf is heavier, it will fall down easily, right?"

Having said this, Bai Di raised the corners of his mouth slightly, and still looked at Bai Niao and the others gently. A trace of confidence flashed in his eyes. The warm sunshine shone on his hair, shining like silver, and Miwako couldn't help but be stunned. For a moment,

"By the way, after the knife stabbed the victim to death, the book would naturally fall out, and the murderous knife would be inserted into the body, and then fall to the floor."

"Finally, as long as you put away the scattered books, no one will discover this design."

"But, Mr. Baidi," Mr. Masuo couldn't help laughing and defended quietly,

"If I really put the knife on the bookshelf, no matter what, my wife will find it."

"Then," Bai Di took out a book and placed it on the exposed end of the bookshelf.

"So what?"

Bai Di looked at a few people in amusement.

"So that was the case, so the knife was no longer obvious, and the reason why the murderous knife was inserted horizontally into the body of the deceased was explained."

Miwako couldn't help but took over the words. She looked at Bai Di with beautiful eyes filled with admiration.

It's true that Bai Di was able to notice things we didn't notice so quickly.

"Moreover, in this way, even if we come in full force and see the bookshelf and books falling all over the floor, we will definitely think that it was caused by a fight between the murderer and the victim, and it will be even harder to find out that this was a deliberate set up by the murderer. It's shut down."

Takagi continued to add

"So, is this really the case? Mr. Masao?"

Bai Niao couldn't help but turn around and asked doubtfully.

"So, what about that line?"

Mr. Masuo couldn't help but struggled and said,"What about that kite line? As you said, the kite string was left on the axle wheel. If the criminal police discovered it, wouldn't everything be exposed?

Besides, what evidence do you have that this is a trap set up by me?"

However, when he heard this, Bai Di suddenly patted his head, as if he suddenly remembered something, and couldn't help but said to Miwako beside him,

"By the way, Miwako, Mr. Masao was injured just now."

"Injured?"

Miwako glanced at Mr. Masuo in confusion, her pretty face full of confusion.

She didn't even see that Mr. Masuo was injured.

"It's a finger, a finger. Bai

Di pointed to Mr. Masuo’s left hand and said with some regret,

"Mr. Masuo is really unlucky. Just now he wanted to put his hand in his pocket, but it was pricked by something. It seems that Mr. Masuo is really not very lucky today."

0..............

Seeing Bai Di shaking his head to express regret, people who didn't know better thought that Bai Di was really saying that Mr. Masuo was unlucky.

"You have something in your pocket, right?"

Miwako took a step forward, and a pair of bright beautiful eyes hurriedly glanced at his left hand.

Noticing the looks of Miwako's three policemen, Mr. Masuo subconsciously retracted his left hand and hugged it in front of Miwako.

"Can you please take it out?"Takagi walked up to Mr. Masuo and stretched out his hand.

However, when he saw Takagi's outstretched hand, Mr. Masuo was frightened and took a step back.

"I think the thing in his pocket is probably the tape with thumbtacks or something on it, and there should be blood stains of the victim on it."

Shiratori guessed quietly, which surprised Miwako.

"Really? How did you know?"

"As soon as I saw the neatly edged blood stain on the bookshelf, I knew there was something attached to it."

Shiratori pointed to the edge of the top panel of the bookshelf and said,

"You only need to adjust the direction of the thumbtack, stick it on the top of the bookshelf with tape, then make a loop of the kite string and hang it on the thumbtack. When the bookshelf falls, it will quickly detach.

As for the loose line, it will naturally roll up to the axle due to the inertia of the bicycle's rotation."

"However, if the blood stains and thumbtacks were discovered by the police, how would he explain it?"

Takagi asked puzzledly.

"Humph, it's extremely simple."

Bai Niao then walked up to the bookshelf, took down the paper that said 'Today's target - 2kg' that Bai Di had pressed on the paper knife, and motioned to show it to a few people.

"I think he would say that the top of the picture was used by his wife to pin this weight loss goal on the bookshelf behind the bicycle.

As for the blood stains, it was because his wife accidentally pricked her finger when she was trying to remove the board."

Hearing this, Mr. Masuo's expression suddenly changed, and finally he lowered his head helplessly.

"However, facts speak louder than words."

Shiratori walked up to Mr. Masuo and continued,

"Let’s do an experiment to see if this method can be successful. Now please stick the items in your pocket back to the bookshelf."

Hearing this, Bai Di finally breathed a sigh of relief and looked at the three white birds with some relief. Their smiles were gentle and plain._Fei
