In the quiet office, the sound of keyboard tapping can be heard from time to time. In order to facilitate contact with Miyano Shiho, Narumi Kiyotaka spent a lot of effort to compile a small program, in short, it is a chat tool similar to QQ. Although Narumi Kiyotaka thinks it's nothing, it's very novel in the eyes of others, after all, it's also the world's first online chat tool.

Shiho Miyano sent a message, "You invented this?" It's so easy to use. What does this Dragon mean? ”

Narumi Kiyotaka replied, "Nickname, you can also give yourself one." ”

After a few moments, the name on the dialog changed to grey, which was the nickname that Miyano had taken. Vaguely guessing the other party's thoughts, Narumi Qinglong said: "Look away, don't be so dark in your heart." ”

After a long time, Miyano Shiho replied, "Today they killed another person with the medicine I made, how do you let me see it?" ”

Narumi Kiyotaka suddenly felt like he had hit the muzzle of the gun, and after a pause, Narumi Kiyotaka replied: "You are studying medicine, and you should know that many drugs can be used to kill people and save people. How you use it depends on the person who uses it, not the person who makes it. ”

Shiho Miyano said: "But the medicine I made can only be used to kill people. ”

Narumi Qinglong said: "There are many ways to kill people, why spend so much energy and material resources to research a poison?" Are you sure this drug can only be used to kill people? ”

Shiho Miyano didn't move for a while, and just when Kiyotaka Narumi thought that the other party might not want to talk anymore, Shiho Miyano suddenly said: "Do you believe that there is rejuvenation in the world?" ”

The corners of Narumi Kiyotaka's mouth raised slightly, and when he was about to reply, there was movement at the door, and Conan had returned from school.

"When did you start playing with computers so much?" After not seeing each other for a few days, Conan discovers that Kiyotaka Narumi is often in front of a notebook.

Narumi Qinglong said lightly: "In the future, it will be the Internet era, and detectives also need to keep pace with the times. ”

Conan pouted, now that the Internet is just getting started, who would have thought that in a few decades, oh no, it would be half a year later, it would develop to that point.

"Why did you come back so early today? Didn't play with Ayumi and them? Narumi Kiyotaka changed the subject.

"I'm a high school student, why do I want to be with them every day?" Conan didn't have a good airway.

"I think you didn't have a lot of fun with it, didn't you?"

"Who, who's having fun?"

Chatting and chatting, suddenly the phone rang, and Narumi Kiyotaka picked up the phone, "Hello, this is Narumi Detective Agency." ”

"Excuse me, Brother Narumi, I'm Twilight Thirteen."

"It's Officer Twilight, what's the matter?"

"Do you have time now? I just came across a tricky case here, and I'd like you to come over and take a look at it. ”

"Okay, where are you now?"

"I'm ......at the scene of the crime," Officer Twilight said, giving the address.

After hanging up the phone, Conan couldn't wait: "Got a new case?" ”

"Hmm." Narumi Kiyotaka replied casually. Don't forget to reply to someone before you go.

In the laboratory, Shiho Miyano saw the last reply, just a simple belief, and for some reason, he was inexplicably a little happy.

The other party was originally just a hacker who met in Pingshui, although she was willing to help, but she didn't have much expectations, with her understanding of the organization, even if the other party helped call the police, it was useless. Unexpectedly, the other party directly gave him a lot of suggestions, what to retreat as advance, deliberately angry, a series of seemingly nonsense actions, although they did not save her, but also let her see a glimmer of hope in the dark.

Ten minutes later, Narumi Kiyotaka and Conan arrive at a Japanese-style mansion and find that in addition to Officer Twilight, there is also an acquaintance. Seeing Narumi Kiyotaka coming, Maori Kogoro suddenly looked unhappy, there was already a detective like him, and Officer Twilight actually called this kid here, it was just a superfluous move!

"Brother Narumi, you're finally here!" Seeing Narumi Kiyotaka, Officer Twilight was like seeing a savior, and his face was indescribably happy!

When the rest of the people in the room heard this, they all focused their eyes on Narumi Kiyotaka. They have also heard of this famous detective, and their expressions are different, some are calm, some are nervous.

Narumi Kiyotaka looked directly at the corpse on the wall not far away, holding a knife in his hand, and a knife was inserted in his chest, and there were marks left by slashing everywhere on the surrounding cabinets, walls, and ceilings.

"The deceased's name is Jiro Marukawa, 51 years old this year, the owner of the house, and the time of death is 3 to 5 p.m. The deceased is said to have practiced kendo and has been three dans. Looking at the situation in the house, he should have fought fiercely with the murderer, and the gangster must also be quite a powerful master. Officer Twilight explained.

"If there is a fierce battle, there should be a lot of movement at that time, and even if no one notices, there will not be a single gap in the weapon." Narumi Kiyotaka pointed to the knife in the deceased's hand, and saw that the blade was intact, like a new knife.

Maori Kogoro said disdainfully: "It shows that the murderer is very strong, and Mr. Maru didn't catch a knife." ”

Narumi Kiyotaka pointed to the surrounding traces, "If the murderer's strength is far above Mr. Maru, will he fight like this?" ”

Mori Kogoro defended: "Maybe Mr. Maru feels that he is not an opponent and has been trying to escape. ”

Narumi Kiyotaka pointed out the door, "There are so many opportunities to escape, why don't you just rush out?" It's okay to just shout for help, did anyone hear it at the time? ”

Mori Kogoro was speechless for a moment, and Officer Twilight felt justified and couldn't help asking, "Then where did these traces come from?" ”

Narumi Kiyotaka looked around at everyone, "Maybe the murderer deliberately stayed, in order to cover up some evidence against him." ”

For a while, many people's faces changed. Referring to the evidence, Officer Twilight took out a notepad and said, "This is a notepad left by the deceased, which records his daily schedule." According to the records, a total of four people will visit this afternoon. They are Mori Kogoro, Yuji Suwa, Hatano Kiya, and Makoto Akutsu, that is, all four of them, and they are all suspected. ”

The four of them were in the house at the moment, and Maori Kogoro was the first to jump out and retort, "I took his commission and came to make a report, he was still alive at the time, but someone else came to visit him halfway, he left temporarily, I waited for nearly two hours, and then I couldn't help it, so I came to check, and it turned out that he was killed." ”

The first person to discover was none other than Mori Kogoro. According to the Japanese police's habit of solving cases, the first person to find the deceased is the most suspicious, but Maori Kogoro came alone today, and the content of the report is relatively private, Marukawa Jiro deliberately broke away all the servants, and the result was that no one could testify to Maori Kogoro.

"I think you killed my husband and said that there were other people visiting, and there was no one else at that time except you." In addition to the four suspects in the house, there is also a woman in a kimono, who is none other than Marukawa Jiro's wife, Maruinako.

Maori Kogoro said angrily: "I think you killed your husband, Mr. Maru asked me to investigate your affair before, you must have already found out, so you deliberately killed him." ”
