[Conan Doujin] Let's become smaller together

The author has something to say: Sato-san _(:з」∠)_

"The trick! The trick!" Kitagawa Kenichi hesitated for a long time, and finally decided to believe that his fiancée didn't kill anyone, so he stepped forward to protect her, "Shiina, she didn't pour anything into the ice cream, and she didn't let anything go You are right, right, I have never seen her act like this!"

Gazed by Kitagawa Kenichi's gaze, Hoshino Aoi and Matsumoto Kiyoo, who already faintly believed that Shiina Shimizu might be the murderer, nodded involuntarily.

Not only to support their companions, they did not see Shiina Shimizu adding anything to the ice cream.

"Hey, hey!" Because of the support, Shiina Shimizu felt that his cold palm held tightly by Kenichi Kitagawa gradually warmed up, and he quickly defended himself: "The highly corrosive thing like phenol must be Use something to hold it, the one you hold in your hand, little brother hora, is an example."

"Ring." This time it was Sato who answered, "You don't need to use your hands, you just need to use the ring to do it."

Dr. Ari, the Detective Boys, and Takagi all looked at Sato in surprise. Has she already seen through the method of this case?As expected of Police Officer Sato, his brain turns faster than everyone else.

In fact, not only is her brain turning faster than everyone else, but Sato's observation is more detailed than Conan's, because she discovered the crux of the problem in this case before Conan, but after all, she is not as smart as Conan and can't figure out the method.

But Conan has already reasoned to this point, plus some previous sporadic hints, there is no problem in solving this case.

"Well, I was a little confused before, because I felt that the size of your ring seemed to have changed, but I didn't find anything wrong. But the person in the forensic class told me that when Conan-kun found that there seemed to be something wrong with the photos taken by Matsumoto Kiyoo-san , I took a closer look, and finally found something wrong." Sato didn't hear Conan's phenol color theory, but found the problem from another aspect.

"Look at these two photos—" Holding up the digital camera, Sato deliberately zoomed in on a certain place, "Didn't we meet again by chance after riding the roller coaster? The first one is the group photo taken by all of us at that time. After that, Shimizu-san went to the toilet, didn’t you take another picture with the mascot when you came out? Look at the difference between the two pictures—”

Sato adjusted the photos, and everyone found that the petals made of wire on the outside of Shiina Shiina's ring in the second photo seemed to have a wider opening.This change is invisible if you don't notice it, but it's quite obvious once you notice it.

"In just 10 minutes, the shape of the ring changed. Then you suggested that everyone go to buy ice cream, and Takagi and I decided to go play the pirate ship and leave. Not long after that, the murder happened." Sato stated lightly After watching what happened, I finally came to a conclusion, "The shape of your current ring is the same as the one in the first photo. Then, can we make a bold guess about what you did with your ring, for example—— "

"Poisoning." Takagi also understood, "That's how it is! If you freeze the phenol in the ice cube at the beginning, and then fix it with that wire, because the phenol is transparent, no one will notice it. Because it is ice cubes, even if you eat the victim, you will not pay too much attention, so you only need to put the ring close to the ice cream to release the poisonous ice cubes, and you don’t need to make a 'putting something' action to poison. And This ring was originally modified by you, for you, the main force of the model club, it would not be too difficult to make the iron net into a clip that can be opened and closed!"

"I—ah!!" Shiina Shimizu tried to deny it, but suddenly felt that her left hand was being grabbed!

She looked down, it was Conan.

Conan smiled at her, and forcefully and irresistibly opened her hand. There was a small wire loop standing up on the part of the ring facing the palm.

With a light press, the petal-like barbed wire on the gemstone on the back of the hand opened gently with Conan's force.

It is as beautiful as a blooming flower, shining pink.
