It was nearly dusk. Pen, fun, pavilion www. biquge。 info

The slender silver line does not fade in the sunlight and cannot be seen clearly, but will refract a faint brilliance in the faint yellow light, and this brilliance is following the gap between the door and the wall becoming smaller and smaller, becoming thinner and tighter.

The dummy was controlled, and at this time Kurosawa Silver was standing behind it to simulate the action of Shinagawa's right lips touching the milk bottle, but the pull force on the milk bottle to the outside came without warning, and due to the force, the hand was pulled forward, and the whole body of the dummy was also stumbling forward.

Kurosawa Silver let go completely, and at the same time, he took the opportunity to snatch the plastic bag containing the firearm in the hand of the police officer standing nearby, and dropped the item at the doll's feet.

The puppet stumbled uncontrollably, and finally lost its balance completely, smashed its head to the ground, and made close contact with the fruit knife that was fixed on the ground with ice cubes not long ago, the handle of the knife against the door, and the blade above it, half of the face of the mannequin was dented in, and the milk bottle in his hand also flew out of his hand and shattered into slag.

Theoretically, the coils that had come loose to the ground due to the shattering of the milk bottle should have stayed where they were without the blessing of tightness, but the steel wire tied to the balcony was wrapped around an ice cube and tied to both ends with a dense and small weight.

Due to the pressure, the steel wires that were originally located on the ice are constantly descending and penetrating deep into the inner layer of the ice.

This descent also drives the coil to start moving along a set route.

It moves the distance towards the door of the rooftop, bypasses the doorknob and lands again, and then runs towards the handrail of the roof, gradually approaching the handrail of the roof.

A size-limited ferrule is hung on the handle of the fruit knife in advance, and the lower part of the ferrule is placed at the lower end of the blade, and the top of the ferrule is tied with a thin wire and connected to the coil.

In the process of the coil moving towards the door, the ferrule also moves forward, but the obstruction of the knife handle makes its lower end of the range of motion limited to the front end of the tool handle, and the upper end will not leave the tool handle to the maximum extent until the coil is wound back again, the lower end of the ferrule moves backwards, and the upper end also moves backwards, autonomously pulling the neck of the dummy back.

The force is so great that it also makes the dummy and the fruit knife disengage.

The dummy gradually turned around because of the noose, and moved with its head towards the roof railing, but its body was still close to the ground, and because there were fragments of the container that used to hold milk on the ground, they more or less injured the dummy's body, and the dummy's face obviously had a few more scratches.

But the steel wire continued at the lower limit of the ice, and the coils and ferrules were pinned down to move.

As time passed, the dummy's body finally approached the railing of the rooftop.

The wire pierced through the ice and fell with a thud.

According to common sense, the lower body of the dummy will automatically tilt to the ground due to the downward center of gravity during the fall, causing the upper and lower body to show a certain angle at the waist.

However, the steel wire fell in a straight line under the pull of the weight, accelerating its movement, and the coil tightened the dummy's neck, pulling the dummy out at the moment of falling.

The reason for the height difference, the dummy descended from the rooftop, went straight over the balcony, and followed the fall of the steel cable tied to the heavy object.

For the reason of inertia, the body of the dummy crossed the balcony, and since the center of gravity was still in the lower body, the body was thrown forward.

And the ferrule had been touched not long ago, and the top had been cut with a fruit knife, and somewhere it was slightly finer.

When moving on the roof, the force between the ferrule and the steel wire to which it is connected is within the tolerable range, and when doing parabolic motion, the force on the steel wire is added to the weight of the dummy.

Common sense says that the wire will break, but due to the small action on the ferrule not long ago, the ferrule will break automatically.

The dummy's corpse began to fall freely.

Rings, coils, and other steel wires that are connected into a line will fall to the ground slowly due to factors such as volume and quality, or even blown away by the wind.

But even if the evidence were to appear at the scene, no one would notice it, and it would only be regarded as a child's prank.

At this point, this experiment is completely over.

......

"That's pretty much the way the murderer committed the crime. Kurosawa looked away from his watch and glanced at the onlookers, "It takes less than three minutes overall, and these three minutes are enough for the murderer to prepare a lot of things." ”

There was a moment of silence on the rooftop.

But the silence was broken, replaced by a flurry of astonishment.

"Awesome. Twilight was unstinging in her admiration at this time.

"Of course it's amazing, a murderer who can come up with this kind of technique. ”

Kurosawa Silver put one hand under the railing of the balcony, and his eyes were slightly moving when he looked at the mat that had already been prepared below.

Not only can an alibi be created, but this modus operandi can also almost annihilate all the evidence, and it is difficult for him to take pains. ”

"No, I'm not talking about the murderer, I'm talking about Brother Miyamoto, you're ......" Twilight sneered on the side, "Compared to you, the criminal police on our side are simply far behind, you solved the case in a few minutes, but we didn't come up with any clues for a long time, it seems that there is still a lot to learn......"

"It's just that you didn't find the key, and the search wasn't too good. Kurosawa's voice was cold.

"Do you mean you jumped off the rooftop to the balcony on the 23rd floor?"

"Naturally. Kurosawa nodded, "At least you should have searched the room below the jump, not just interrogated." ”

"This is indeed our negligence......" Twilight nodded.

Sixteen tilted his head to the side to look at this happy scene, and was silent for a while, but finally put his hand into a fist and put it to his lips and coughed softly.

It wasn't loud, but it was enough to divert the attention of everyone present.

"What, Miss Sixteen, do you still have questions?" Kurosawa looked sideways at Sixteen.

"Of course. Sixteen nodded heavily.

Say. ”

Sixteen, who received the promise, immediately stretched out his hand and pointed to the ground, "You said that there was no evidence left, so how can you explain these glass fragments? When our police came here, they didn't see these things on the rooftop." ”

"Who told you this was glass?" asked Kurosawa rhetorically.

"Isn't it?" Sixteen was stunned.

"It's a glass-shaped utensil made of ice cubes and covered with plastic wrap. Kurosawa smiled and said, "When the utensils shatter on the ground, small pieces of ice will melt quickly in direct sunlight, and the plastic wrap will float away on its own." ”

"It's just that I don't have enough time now, and I can't see the effect for the time being. ”

"You can go and see the weather forecast. Kurosawa Silver pointed upward, "The weather has been good lately. ”

“...... The modus operandi you deduced is indeed powerful enough, and you confess the truth to us in a way that is intolerable to common sense. A faint smile appeared on Sixteen's face, "However, the successful implementation of the method just now was only successfully carried out after we solicited the residents under the rooftop, and the murderer did not have this capital ......"

She began to talk about the possibility of crime again.

"Didn't you say the murderer was a janitor?" Kurosawa spread out the report that Twilight had brought in front of Sixteen, poking his finger into one place, "This apartment is cleaned by the same cleaning company, so it's easy for a janitor to want to mix into two rooms at the same time." ”

"Besides. Kurosawa Silver flipped the paper over, "It is said that the residents under the roof will not return home until the evening, and this time it happened that he came early and was stopped by the police, and he entered the house after the interrogation, and from the fact that he closed the curtains tightly, he knew that he had not entered the balcony from beginning to end today, how could he find anything." ”

“...... What do you explain the shoes on the railing?" Sixteen pointed to the place where the white tape was enclosed, and asked rhetorically, "Miyamoto-sama didn't mention in his modus operandi that shoes and the like would be left in that kind of place. ”

"It was put up in advance by the murderer in order to confuse you all. Kurosawa glanced at Sixteen, "I said when I was downstairs that Shinagawa Youta has been wearing slippers, so he also has slippers on his feet when he hurries up to the rooftop." ”

"Then why go out of your way to prepare shoes and not just put slippers on them?" Sixteen frowned.

"If you put the slippers, I think you'd already find out whose footprints were on the door of the Shinagawa residence downstairs through the shoe patterns under the slippers, right?"

“...... I see what you mean. Sixteen was silent for a while, and then a bright and lovely smile appeared on his face, "Then for this case, there is no problem for people, thank you Miyamoto-sama for relieving most of their doubts." ”

"It's all people from the same institution. Kurosawa Silver replied with a pun, "So, you, as well as the criminal police in Tokyo, should also follow some clues to investigate the murderer as soon as possible, and if you catch it as soon as possible, I think the safety of the eldest young master is also guaranteed." ”

Hehe. Sixteen's eyes involuntarily crossed a cold light, but on the surface, he rubbed his fluffy hair strangely, and blinked at Kurosawa Gin: "But people think that this case may have nothing to do with Kurosawa-sama......"

"You're saying that if it was against him, the murderer wouldn't have prepared in advance, right?" Kurosawa Gin's eyes were dyed with a faint smile, "Well, yes, everything could be a coincidence...... However, it is difficult to guarantee that this is not a coincidence calculated by the real culprit behind the scenes. ”

"If that's the case, then the murderer...... It's terrible!" Sixteen bit his lip and shook his body a little pitifully, "People will stay by the side of the eldest young master as a guarantor in the near future, and face such an opponent with the eldest young master, and I don't know if the eldest young master will survive until that time......"

"......," Kurosawa said, "who knows." ”
