Hattori Heiji was so careless that he didn't take it seriously. He held a lunch and came to Chi Feichi, "Okay, Feichi brother, don't be angry. I understand your feelings of wanting to cover Nanatsuki-san, and I also want to cover He and Chi Feichi."
Ye, after all, she is always following me, and she is clumsy, like a little brother who needs a lot of care from the boss..."
Koshizu Nanatsuki: "?"
is that so?
Toyama Kazuye: "?"
Is this actually the case?
Mao Lilan: "..."
I'm really worried that Brother Fei Chi will be led astray by Hattori.
Hattori Heiji patted his chest again and said with emotion, "Fortunately, I'm not the kind of person who makes people worry!"
"You are more trouble-free than anyone else." Chi Feichi couldn't help but say.
In fact, if someone he didn't know outside suddenly sneered at Hattori Heiji, he would be a little unhappy and want to slap Hattori Heiji so that Hattori Heiji could smack him back quickly.
Of course, Hattori Heiji really doesn’t need him to supervise and will definitely spray it back as soon as possible, but that doesn’t mean Hattori Heiji makes people worry-free, right?
"What are you talking about?" Hattori Heiji expressed his dissatisfaction with Chi Feichi's evaluation in a black line, "How can I not make people worry?"
Conan smiled and raised his head, "I think Brother Chi is right."
Hattori Heiji leaned over and said jokingly, "It's better than a kid who makes everyone worry that he can't stand hunger, right?"
Conan's half-moon eyes, "Isn't it better than a guy who buys dinner out of kindness and makes others angry because he doesn't appreciate it?"
On the side, Mouri Kogoro glanced at a group of people with disgust, "Children are children..."
"Officer Megure!" A forensics officer shouted at the entrance door holding an evidence bag containing a pair of slippers, "We have tested the slippers of the deceased Mrs. Wakamatsu and found that the upper surface of the right slipper contained a toxin reaction. However,
The black tea, pens, and eye drops on the desk are free of toxins, and other things in the study are still being tested!"
"Okay, then please continue to investigate the study carefully, and then come out to eat!" Mumu Shisan said seriously, softening his expression, "Brother Chi and Miss Yueshui also brought lunch boxes for you, and now there are still some
It’s a lot, but I have to force you to eat a cold lunch..."
"It doesn't matter, it's great to be able to eat after working overtime." The forensic officer smiled and turned back to the house.
"Well..." the maid Sakurako Yonehara said weakly, "There is a microwave in the kitchen. I think it would be okay to heat up the bento."
"Let's talk about it then," Megure Thirteen did not agree in a hurry and looked at the four people, including the maid Sakurako Yonehara, seriously, "Miss Yonehara, Miss Satake, Mr. Shiina and Mr. Fujinami, please eat as soon as possible.
After finishing things, I would like to ask you about the situation of the Wakamatsu family!"
"Ah, yes!"
The four people immediately lowered their heads to eat in cooperation, silently speeding up their meal.
Koshimizu Nanatsuki looked at the four people over there and whispered, "In other words, all three members of the Wakamatsu family have been killed now?"
Only then did she realize that this could be considered a tragedy.
"Yes," Hattori Heiji said thoughtfully, not in a hurry to eat, "In the case of President Wakamatsu, the Yamato police officer in charge of the investigation in Nagano Prefecture has already figured out the clues. The tiles in the bathroom at the scene of the crime were actually made from top to bottom.
It is a rhombus-shaped tile with an acute angle of thirty to forty degrees..."
"Is it a 'weird rhombus'?" Koshimizu Nanatsuki confirmed with some surprise.
"That's right," Hattori Heiji nodded, "Use visual effects to make the tiles look like a gradient from top to bottom. In fact, every tile is the same color. When President Wakamatsu was killed, blood was indeed used.
A pre-death message was left on the floor, but the tiles were moved to other places and hidden. Due to the optical illusion, the police did not suspect that the tiles were moved to other places in the bathroom. Of course, Officer Yamato has found it.
Those tiles, and using the blood stain reaction test, restored the message that President Wakamatsu left before his death. The message that President Wakamatsu left was...son!"
"Son?" Koshimizu Nanatsuki followed and thought, "Does it mean his son, Mr. Ikuro? But Ikuo said before that Mr. Ikuro was killed, and the person who killed Mr. Ikuro..."
"It should be Mrs. Wakamatsu. Mr. Ikuro died of poison after eating the Baumkuchen, but he ate the same cake as us, and the cake was completely divided into eight equal parts, allowing us to take it ourselves, even though he had a stomachache at the time.
Hungry, but the cakes are divided equally, not one piece is bigger than the other, and the murderer has no way of predicting which piece of cake he will take." Hattori Heiji took the opportunity to explain the situation and sorted out his clues, "And after testing, except for him eating
There is no toxin on the piece of cake, and there is no toxin on other cakes. In addition, when he is hungry, he likes to grab the cake with his hands and put it into his mouth. This is something that everyone who knows him knows. Therefore, the murderer may have put poison on it from the beginning.
He accidentally touched it, and then used his habit of holding cakes with his hands to put them into his mouth to poison him..."
Koshimizu Nanatsuki nodded silently.
There is no problem with this idea.
"Later, the police discovered that there was toxin on the door handle of the room, and there was also poisonous powder residue on the ground under the door handle. There was an unnatural disconnection within the range of the poisonous powder," Hattori Heiji said, unable to help but look up.
Xiang Chi Feichi and Koshizu Nanatsuki asked seriously, "You must have thought about it, right? The murderer sprinkled poison powder on the door handle, and the poison was also stained somewhere..."
Koshimizu Nanatsuki thought of what the forensic examiner said before, "Is it... a slipper? The forensic examiner said that there was a poisonous reaction on the upper surface of Mrs. Wakamatsu's right slipper. If she stood at the door of the room and sprinkled poisonous powder on the door handle, the poison would
It is very likely that the powder accidentally fell on the slippers, and since there is residual poisonous powder on the ground and traces of it, it is basically certain that the murderer did spill some of the poisonous powder when he applied the poison."
Hattori Heiji nodded and continued, "Everyone was moving around the house before. It would be very difficult to quietly change the slippers on someone's feet, right? Then..."
"It's not difficult," Chi Feichi, who was standing with his head down eating, decided to push forward and go back to rest early, and said out loud, "When we entered the house to look for you, we passed by the bathroom. There was a pair of slippers outside the bathroom, but there was a pair of slippers in the bathroom.
No one, those should be special slippers for changing into the bathroom, that is to say..."
When Mrs. Wakamatsu puts on the special slippers to go to the bathroom, she will leave her original slippers outside the door. The murderer can take the opportunity to exchange his toxin-stained slippers with Mrs. Wakamatsu's slippers and wait for Mrs. Wakamatsu.
When he came out of the bathroom, he put on the pair of slippers with toxins on them and became a suspect!
Hattori Heiji and Conan also thought of this, their expressions changed, and they immediately ran towards Toyama Kazuha and Maori Ran who were eating together.
"Kazuha!" Hattori Heiji asked anxiously, "When you and Xiaolan first arrived at Wakamatsu's house, did you go to the bathroom, right? Is there a pair of special slippers for the bathroom at the door? Did you change them at that time?"
Toyama Kazuha originally wanted to say, 'How could I know that because I'm so stupid?', but seeing Hattori Heiji's anxious expression, he didn't give in and nodded, "Yes, yes, when we went to the bathroom, there was a pair of slippers outside.
Moreover, Mr. Yulang was in the bathroom at that time, and we waited for him outside the door for a while. When he went out, he said that they were special slippers for entering the bathroom, so we put them on..."
Hattori Heiji was startled and then said hurriedly, "Wait, wait a minute! You said that when you went to the bathroom, you met Mr. Ikuro coming out of the bathroom. Do you know if he washed his hands at that time?"
Yuan Shan and Ye were speechless, "Who doesn't wash their hands after going to the bathroom? That's so unhygienic!"
Mao Lilan recalled for a while and affirmed, "When Mr. Yulang came out of the bathroom, his hands were wet. When he walked to the living room, he was wiping his hands carefully with a handkerchief."
Hattori Heiji:"……"
(=ｘ=)
He remembered that after they entered, Mr. Yulang came out of his room and went to the other side of the corridor. Then he went from the corridor to the living room and ate the cake directly with his hands.
Their previous reasoning was based on the fact that after Mr. Yulang left the room and pulled the door handle with his right hand, the toxins on his right hand were not washed away. But if Mr. Yulang washed his hands after leaving the room and eating cake in the living room...
Conan: "..."
(=ｘ=)
The toxins have been washed away, and the hands have been wiped clean with a handkerchief. How could it still get on the cake and poison someone to death?
Their previous thinking was completely wrong!
Seeing Hattori Heiji standing still, Toyama and Haha asked in confusion, "Heiji, what's wrong? Is there any problem with Mr. Ikuro going to the bathroom..."
Koshimizu Nanatsuki, who followed next to him, was carrying a lunch box and took a bite of rice. "His previous reasoning has been overturned."
Hattori Heiji came back to his senses, twitched the corner of his mouth slightly, lowered his head and looked at Conan, "Yes, everything from the murderer to the method of committing the crime has been completely overturned."
Conan: "..."
That's right, it made him feel like a malfunctioning roller coaster...
Chi Feichi also followed him with a lunch box, freed up a hand and rummaged in his pocket, "Hattori, please stretch your hand."
Hattori Heiji was confused, but he still took the lunch box and chopsticks in his left hand and stretched out his right hand towards Chi Feichi, "Is that so?"
"I couldn't find the props, so I'll make do with it." Chi Feichi found a pen from his pocket, bit the pen cap with his teeth, pulled it out, and used the pen to draw an arc with up and down lines on the palm of Hattori Heiji's hand.
The trapezoid, "Suppose this is a cut piece of Baumkuchen..."
Hattori Heiji nodded repeatedly, "Yeah!"
"This is another piece..." Chi Feichi drew another trapezoid with the sides aligned under the pattern, "If you were hungry, which piece would you choose?"
Two trapezoids with curved upper and lower lines. After aligning one side, the upper trapezoid looks much larger than the lower trapezoid, but in fact, the two trapezoids are the same size.
If this were a cut Baumkuchen, a selfish and hungry person would undoubtedly choose the larger cake on top.
Hattori Heiji quickly reacted, staring blankly at the pattern on his palm and murmuring, "So, it's Jastrow's illusion... There is no such thing as 'the cake is divided equally, I'm not sure which piece Mr. Ikuro will choose'. Using vision,
The illusion is that the murderer can make him choose the poisonous piece..."
