Of course, the speculation about maggots is not over, and everyone in the living room of the villa waits extremely quietly for what Ogata has to say.

"The time of death is inferred to be after twelve o'clock when we last met Chikako Ikeda, and based on the color and length of the maggots, based on the time of growth during the neonatal period, it is likely that the deceased was killed by the killer between 1 and 3 o'clock in the evening."

Ogata looked at everyone, and then said in detail: "Between one and three o'clock, it is the time when everyone goes to sleep, and it is a very vague range. So in order to narrow down this range, we also have to start with the nodes on these maggots. ”

As he spoke, he used his tweezers to gently pick up the maggots that had been writhing, because he was afraid that his body would be exploded if he used force, so he was extra cautious.

"The so-called patches are the ring-shaped patterns that can only be identified carefully every time it wriggles or expands and contracts its body. I think everyone should know that to determine the age of a tree, you need to start with the growth rings. Similarly, the patches on these maggots can also be said to be the best proof of how long they have survived. ”

Although everyone was interested, they still couldn't overcome their disgust, and they couldn't follow Ogata's words to deliberately observe how many spots there were on its body.

"This maggot has a total of 12 nodes, and the growth time of each node is about 3o minutes, which means that the maggot survives for six hours." Ogata explained slowly.

Hiroki Kakutani asked suspiciously, "Then how do you calculate the specific time?" ”

Ogata glanced at his watch and said lightly, "It's 8:40 Tokyo time." To calculate the exact time, you have to be down to the last detail. Maggots are used to corrupt corpses or meat to speed up their growth, and the calculation time of thirty minutes per node is the result of the actual yàn of the gò. And when it reaches maturity, it needs at least fifteen nodes, which is the limit of node growth. ”

"It took me forty minutes to remove it from the periosteal layer of the deceased's braincase, during which time its growth slowed down by nearly half an degree. It takes at least an hour for the corpse to start with the birth of maggots, and the plaques we tested are about six hours, and the time of death continues to narrow the deviation from one point as the starting line, around two o'clock. And as I said earlier, after the maggots are removed, the growth will be slowed down by half, and this part of the time should also be counted. ”

When Ogata said this, everyone was secretly thinking about it in their hearts, and his voice paused: "Twenty minutes." After the deviation was narrowed to a certain range, the precise time of death was around 2:20 in the middle of the night! Under the influence of some uncertain factors, the possibility of deviation will be controlled within ten minutes. This time was also the last moment for the deceased, Miss Chikako Ikeda, to bid farewell to this world. ”

Hearing this inference, everyone had to admit that in addition to the amazing theories of forensic science, Ogata's brain power was far from ordinary.

"But at 2:20 we were all sleeping." Ota Katsu scratched his head, thought about it carefully, and said without much impression.

Hiroki Kakutani suddenly remembered something and looked at Ogata: "I remember that the second floor is the room of the Ogata brothers near the outside of the corridor, if there is any movement, or if someone goes to the living room on the first floor, you should know better than us." ”

Conan also looked at Ogata, and indeed as Kakutani said, Ogata didn't close his eyes all night, and if someone really left from the second floor, he should be there soon.

Ogata's gaze looked at Ryoichi Takahashi, who was pushing the frame of his glasses with an indifferent face in the crowd, and the tight aura behind him, and sure enough, it was her

2:20 a.m.!

If he's not mistaken, it's exactly this time when Atsuko, who is a ghost, breaks into his room, grabs his attention, and gives the bastard a chance to do it.

"It's true that I'm on the outside of the hallway on the second floor, and if someone opens the door and walks out of the room to the living room on the first floor, I'll be the first to notice it. But the killer didn't. ”

Sonoko was aroused by his curiosity, and hurriedly asked, "How did you get to the living room on the first floor and kill Chikako Ikeda?" ”

"Take advantage of the chimney." Ogata said lightly.

In an instant, Takahashi Ryoichi's face changed, and his lips trembled slightly.

"What?" Including Conan, they all looked at Ogata in amazement.

Ogata walked to the fireplace and said calmly, "Let's take a closer look out the window and the position of the chimney. Unlike other villas or cottages, the chimney is located at a horizontal distance from the second floor. As long as the murderer pushes open the window without all of us noticing, approaches the chimney, and slides down the chimney with a rope, he will be able to follow the fireplace in the living room down the lì. ”

"Can you really do such a thing?" Ayako said skeptically.

Ogata replied affirmatively, "The chimney's activity space can definitely accommodate a not very fat adult man to pass through, and the second floor is very close to the chimney, so if you try a few more times, the whole operation process will be much more complicated and easier than we imagined." ”

"Mr. Ota, you have been to the chimney just now, and I would like to ask who belongs to the second-floor guest room closest to the chimney?"

Hearing Ogata's question, Ota Katsu thought for a moment and replied to him, "I remember it was Takahashi's"

Ryoichi Takahashi, whose name was mentioned, had a glint in his eyes, and he clenched his fists to prevent himself from showing anything unusual about others.

"Don't get me wrong!" Ryoichi Takahashi hurriedly shook his head, waved his hand nervously, and said, "You all have seen it too, I'm so fat." If you go through the chimney, your body will get stuck in a small space. ”

"That's right, with Takahashi's stature, he really can't do this kind of thing." Hiroki Kakutani glanced at Ryoichi Takahashi, who had a big belly and a blessed figure, and helped him speak.

"Could it be that the bandage monster has been hiding in Takahashi's room, taking advantage of Takahashi's sleep, to use the methods that Mr. Forensic Medicine said to commit the crime?"

Katsu Ota tentatively speculated, and the statement that seemed to Ogata was boundless, but it was agreed by everyone. This is because the image of the bandage weirdo set up by Ryoichi Takahashi before the crime has a certain psychological hint now. So that the first imaginary object in everyone's mind is not their own person, but this imaginary bandage weirdo.

In the silent living room, a pair of eyes looked at Ogata, waiting for his words. Because no one's guess counts, only his inference has a basis.

And Ogata stared at Ryoichi Takahashi and smiled lightly.

"Mr. Takahashi, are you really fat?"
