Conan: I Am Not a Snake Spirit

The atmosphere regained harmony.

Hattori Heiji was careless and didn't take it seriously, he took a lunch box and moved to Chi Feichi's side, "Okay, Brother Feichi, don't be angry, I understand how you want to cover Nanatsuki-san, I also want to cover and Ye, after all, she is always following me, and she is clumsy, like a younger brother who needs to be taken care of by the boss..."

Nanatsuki Koshimizu: "?"

is that so?

Yuan Shanhe Ye: "?"

Is that so?

Mao Lilan: "..."

I'm really worried that Brother Feichi will be missed 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 worry-free than anyone else." Chi Feichi couldn't help but said.

In fact, if someone he doesn't know outside suddenly sprays Hattori Heiji angrily, he will also be a little upset, and wants to slap Hattori Heiji, so that Hattori Heiji can quickly spray back.

Of course, Hattori Heiji really doesn't need him to supervise, and he will definitely spray back immediately, but this doesn't mean that Hattori Heiji is worry-free, right?

"What are you talking about?" Hattori Heiji expressed dissatisfaction with Chi Feichi's evaluation with black lines all over his head, "Where am I not worrying?"

Conan smiled and raised his head, "I think Brother Chi is right."

Hattori Heiji leaned over and jokingly said, "It's better than some kid who makes everyone worry that he can't stand hunger?"

Conan Banyueyan, "Isn't it better than some guy who bought dinner out of kindness and made others angry because he didn't appreciate it?"

On the side, Mori Kogoro glanced at a group of people in disgust, "A child is a child..."

"Officer Megure!" A forensics officer shouted at the entrance with an evidence bag containing a pair of slippers, "We tested the slippers of the deceased Mrs. Wakamatsu, and found that the upper of the slipper on the right foot had a toxin reaction, but The black tea, pens, and eye drops on the desk are all free of toxins, and other things in the study are still being tested!"

"Okay, then please continue to investigate the study thoroughly, and then come out to eat!" Mu Mu Shisan said seriously, and eased his expression, "Brother Chi and Miss Yue Shui also brought you lunch boxes, and there are still leftovers. It’s a lot, but I’m going to wrong you for eating cold bento…”

"It's okay, it's great to be able to eat after overtime." The forensic officer smiled and turned back to the room.

"That..." the maid Yonehara Sakura said weakly, "There is a microwave oven in the kitchen, so I think it's okay to heat up the bento."

"Let's talk about it when the time comes," Megushisan did not rush to agree, and looked at the four people including the maid Yonehara Sakurako seriously, "Miss Yonehara, Miss Satake, Mr. Shiina and Mr. Fujinami, please eat as soon as possible." After finishing things, I want to ask you about the situation of Wakamatsu's family!"

"Ah, yes!"

The four of them immediately lowered their heads to eat in coordination, silently speeding up their meal.

Koshimizu Nanatsuki looked at the four people over there, and said in a low voice, "That is to say, are the three members of Wakamatsu's family all killed now?"

Only then did she realize that this should be regarded as a massacre.

"That's right," Hattori Heiji was not in a hurry to eat, and said thoughtfully, "The Yamato police officer in charge of the investigation in Nagano Prefecture has already investigated the case of President Wakamatsu before. It is a rhombus tile with an acute angle of 30 to 40 degrees..."

"Is it the 'weird oblique'?" Koshimizu Nanatsuki confirmed with some surprise.

"That's right," Hattori Heiji nodded, "Using visual effects, the tiles look like a gradient from top to bottom. In fact, every tile is the same color. When President Wakamatsu was killed, he was indeed killed with blood." A message before death was left on the floor, but someone replaced the tiles and hid them in other places. Due to the illusion caused by vision, the previous police did not suspect that the tiles were replaced in other places in the bathroom. Of course, Officer Yamato had already found it. Those few tiles, and using the blood stain reaction test, restored the pre-death message left by President Wakamatsu, the message left by President Wakamatsu is...son!"

"Son?" Koshimizu Nanatsuki continued to think, "Does it mean his son, Mr. Ikuro? But He Ye 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 and we ate the same cake, and the cake was completely divided into eight equal parts, so we let us take it by ourselves, although he had a stomachache at the time. Hungry, but the cakes are divided equally, one piece is not big and the other is small, 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 the clues, "After testing, except for the one he ate There is no toxin on the other cakes, and when he is hungry, he likes to grab the cake and put it into his mouth. This is something that everyone who knows him knows, so the murderer may have put the poison on it from the very beginning. Let him accidentally touch it, and then use his habit of holding cakes into his mouth with his hands, poisoning him to death..."

Koshimizu Nanatsuki nodded silently.

This way of thinking is fine.

"After that, the police found that there was toxin on the doorknob of the room, and there was also poisonous powder left on the ground below the doorknob. 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 Yueshui Nanatsuki asked sternly, "You should have thought about it too, right? The murderer is sprinkling poisonous powder on the doorknob, and some places are also stained with toxin..."

Koshimizu Nanatsuki thought of what the forensics staff said before, "Is it...slippers? The forensic staff said that Mrs. Wakamatsu's right slipper had a poisonous reaction on the upper. If you stood at the door and sprinkled poisonous powder on the door handle, the poison The powder is very likely to be accidentally dropped on the slippers, and since there is residual poison powder on the ground, and there are such traces, it is basically certain that when the murderer applied the poison, some of the poison powder did fall down."

Hattori Heiji nodded, and continued, "Everyone was moving around the house before, so it's very difficult to quietly replace someone's slippers, right? Then..."

"It's not difficult," Chi Feichi, who was standing aside to eat with his head bowed, decided to push forward and go back to rest early, and said, "When we entered the house to look for you, we passed the bathroom. There was a pair of slippers outside the bathroom, but inside the bathroom No one, it should be the special slippers that are replaced when going to the bathroom, that is to say..."

When Mrs. Wakamatsu puts on special slippers to go to the bathroom, she will leave the slippers she was wearing outside the door. The murderer can take the opportunity to exchange his pair of slippers stained with toxins with Mrs. Wakamatsu's slippers, and wait for Mrs. Wakamatsu When he came out of the bathroom, he put on those slippers with toxin on the upper and became a suspect!

Hattori Heiji and Conan also thought of this, their faces changed, and they immediately ran to Toyama Kazuha and Mori Ran who were eating together.

"Heiji!" Hattori Heiji asked anxiously, "When you and Xiaolan first arrived at Wakamatsu's house, you went to the bathroom, right? Is there a pair of bathroom slippers at the door? Did you change them at that time?"

Toyama and Ye originally wanted to say, 'I'm so stupid, how would I know', but seeing Hattori Heiji's anxious expression, they nodded and said, "Yes, yes, when we went to the bathroom, there was a pair of slippers outside. And 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 slippers for going into the bathroom, so we changed them..."

Hattori Heiji was taken aback, and then hurriedly said, "Wait, wait a minute! Tell me, 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 too unhygienic!"

Mao Lilan recalled it for a while, and said affirmatively, "Mr. Yulang's hands were wet when he came out of the bathroom, and when he walked to the living room, he was wiping his hands carefully with a handkerchief."

Hattori Heiji:"……"

(=xox=)

He remembered that after they entered, Mr. Yulang came out of his room, went to the other side of the corridor, and then went from the corridor to the living room, and ate the cake with his hands.

Their previous reasoning was established, based on the fact that after Mr. Yulang left the room and pulled the doorknob with his right hand, the toxins on his right hand were not washed off, but if Mr. Yulang washed his hands while eating cake in the living room after leaving the room...

Conan: "..."

(=xox=)

The toxins have been washed away, and the hands have been wiped clean with a handkerchief. How could it still be on the cake and poison people to death?

Their previous thinking was completely wrong!

Yuan Shan and Hajian Hattori Heiji were stunned, and asked suspiciously, "Heiji, what, what's wrong? Mr. Ikuro went to the bathroom, is there any problem..."

Koshimizu Nanatsuki who followed next to him was holding a bento box and took a bite of rice, "His previous reasoning has been overturned."

Hattori Heiji came back to his senses, the corner of his mouth twitched slightly, he lowered his head and looked at Conan, "Yes, from the murderer to the modus operandi, it was completely overthrown."

Conan: "..."

That's right, it made him feel like a roller coaster that's broken down...

Chi Feichi also followed to the side with his bento box, freed up one hand, and rummaged in his pocket, "Hatori, stretch out your hand."

Hattori Heiji was confused, but he still held the bento box and chopsticks in his left hand, and stretched out his right hand to Chi Feichi, "Is that so?"

"I didn't find any props, so I'll make do with it," Chi Feichi took out a signature pen from his pocket, bit the cap of the pen with his teeth, pulled the cap off, and drew an arc with up and down lines on the palm of Hattori Heiji's palm with the pen. The trapezoid, "Let's say, this is a sliced ​​baumkuchen..."

Hattori Heiji nodded again and again, "Yeah!"

"This is another piece..." Chi Feichi drew a trapezoid with the same sides aligned under the pattern again, "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 was a cut baumkuchen, a selfish and hungry person would undoubtedly choose the larger cake on top.

Hattori Heiji quickly came to his senses, staring blankly at the pattern on the palm of his hand and muttering, "I see, it's just Jastrow's illusion... There is no such thing as 'the cake is divided equally, and I am not sure which piece Mr. Ikuro will choose'. Illusion, the murderer can make him choose the poisonous piece..."
