My brother is FBI, and I am a crazy wife protector.

One morning after the Bandage Monster case ended, a so-called Edogawa Conan's mother, who called herself Edogawa Fumiyo, came to the office. She took Conan away. There was also a masked person in her car, Conan. Subconsciously I thought they were all from the winery.

Then Conan found a way to escape, and along the way he found the so-called trading place of the two people based on the clues he got from eavesdropping on their conversation. When he thought he was about to be killed, he discovered the two people he thought he was selling. The object of Fang's transaction turned out to be a prank caused by his parents and Dr. Ali.

Afterwards, Yukiko disguised herself as Fumyo Edogawa again, sent Conan back to the detective agency, and gave 10 million yen to Kogoro.

In the next few days, Conan Edogawa, who continued to live in Uncle Maori's house, solved some cases using his identity as Uncle Maori. There are a few more needles in the uncle's neck, and the organization seems to have no tasks recently, so Minghui is still in trouble. He has no excuse to get close to Shiho. Contacting him too deliberately will arouse Gin's suspicion. of.

Of course, the sisters also have the opportunity to chat on the phone.

This morning, Conan caught a cold, and a guest came to the office. He was the famous Kansai detective Hattori Heiji who came to see Kudo Shinichi. When he knew that Kudo Shinichi called Xiaolan and didn't ask about Xiaolan's current situation, he Knowing that Kudo Shinichi might be nearby. Conan was so scared that he broke into a cold sweat. And when he saw that Conan had a cold, he gave Conan a drink of Baigan which he thought could cure the cold.

Then the current diplomat's wife, Tatsumura Koe, came to ask a Mori detective to investigate her son's girlfriend Sachiko. They wanted to invite Uncle Maori to the diplomat's house. Xiaolan was worried because Conan had a cold, so she took Conan with her. Hattori Heiji finally came here. If there was a case, he would not miss it. He told Xiaolan that if she went, maybe Kudo Shinichi would be there, and then Xiaolan took Conan, who had a cold, to the diplomat's house with Uncle Mori and Hattori Heiji.

When they arrived in the study, they found that the diplomat had been killed in the study, and it was a secret room murder. Uncle Maori asked Xiaolan to call the police immediately. After a while, Officer Mumu came to the scene.

The hands, feet and lips of the deceased Isao Tatsumura had begun to turn purple, and there were bleeding spots on the conjunctiva of his eyes, which were consistent with the characteristics of death by suffocation. In addition to the blood spots on his neck and the poisonous needle not far away, everyone speculated that he died from A poison that is instantly fatal. And because the body was still warm and did not show rigor mortis or spots, the time of death should be within 30 minutes.

In fact, the murderer this time is really smart. The study is a closed secret room, so the only entrance and exit for the murderer is the door. The suspect cannot be an outsider, which means the murderer is a member of the diplomat's family.

A needle that was suspected to be the murder weapon was left at the scene, and the victim's lips were purple. It was obvious that he died of poisoning. In other words, now that the time of death has been determined, the next step is to look at the suspect's alibi during this period and to decipher the murderer's murder method.

The other windows in the room were locked from inside, and the door was only opened when everyone came. There were only two keys, one was on Gong Jiang's body, and the other was placed in the double pocket of the diplomat's corpse. However, there were traces of tape in the pendant of the key chain.

After drinking Baigan, Conan's health became worse and worse, and he became unconscious and was sent to rest. At the same time, Hattori Heiji, who was eager to win, seemed to have found some key evidence and began his reasoning - after the murderer killed the diplomat with a poisonous needle, he used the fishing line and the gap under the door to return the key to the diplomat's door. pocket.

The murderer identified by Hattori Heiji was none other than Tatsumura Toshimitsu, the father of the diplomat who was resting in the Japanese room at the time! And he took out the fishing line he found in the Japanese room. After a moment of shock, Toshimitsu Tatsumura also admitted his crime.

Just when Hattori Heiji thought he had a chance to win, Shinichi appeared! He hit the nail on the head and pointed out the loopholes in Heiji's reasoning:

"First of all, when the deceased is sitting, the pants will be wrinkled, and the fishing line can only allow the key to enter the outer pocket, but cannot enter the inner double pocket.

Then the key was originally folded in a V-shape and put into the pocket, which could not be done by using fishing line to deliver the key.

Also, using fishing line to commit crimes will inevitably leave friction marks, but there are no traces at the crime scene. Of course, if the murderer uses this method to create suspicion, it is not difficult to create some traces in advance.

So how did the murderer kill in the secret room? The answer is also very simple, because when the murderer committed the murder, this house was no longer a secret room!

The diplomat likes to listen to classical music, but opera is playing in the room when everyone enters the room to prevent people who enter the room from hearing the screams that the diplomat may make before he dies. There was also a thick stack of books beside him to prevent him from seeing the painful expression he might have before his death.

That's right, the killer officially took advantage of the detectives' blind spot that the killer wouldn't kill in public and created a psychological chamber. She was the diplomat who used the poisonous needle hidden in her keychain to kill the diplomat in front of everyone after they entered the room! The one who was able to do this was Tamura Kimie who went to"wake up" the diplomats at that time!"

Heiji said that the suspect had confessed to himself. Shinichi said that the deceased's father deliberately jumped into the murderer's trap, but he didn't know why.

Shinichi said that the evidence is that the keychain of the diplomat's wife can be opened. There must have been a poisonous needle inside. Later, Koe also confessed when the evidence was solid.

It turned out that Sachiko was the daughter of Koe and her previous husband, and her previous husband was framed by her current husband and father-in-law for dereliction of duty and died. Another diplomat in prison. Kimie herself only found out about the fact that her husband and her father-in-law had framed her ex-husband when her husband found out that Sachiko was that person's daughter. And she had always pretended to hate Sachiko, and it was all It was to protect her daughter.

The reason why her father-in-law jumped into the trap was because he felt guilty about what happened back then.

And she had been pretending to hate Sachiko all the time to protect her own daughter.

The case had just come to an end, and Xin Kazuya used excuses to fool Xiaolan as to why he didn't ask her how she was doing every time. But suddenly he felt something strange again! He seemed to be changing back to Conan!

Shinichi who fell down the stairs left a pile of clothes in the bathroom He transformed back into Conan. He used various reasons to fool everyone and warned not to reveal Kudo Shinichi's name to the outside world. After that, Conan fainted.
