The Journey of the Light-type Superpower

"This deceased must have been poisoned by someone. In addition to a small red spot on the edge of his hair, there was also an iron needle next to the body that was suspected to be the murder weapon... The deceased's lips and the tips of his hands and feet have begun to turn purple, and there are blood spots on his conjunctiva. These are all evidence of death by suffocation...

Therefore, the most likely scenario is that the murderer poisoned the victim to paralyze his nerves, and the poison used was a highly lethal one... He must have been poisoned to death by the murderer within 30 minutes before we entered the study."

Zhao Lan listened to Hattori Heiji's reasoning. Although she thought that what he said before made sense, she still felt that the murderer was Mrs. Tatsumura.

However, she had no evidence to support her statement, and it was impossible for her to tell others based on speculation that she had noticed that Mrs. Darmura had murderous intentions towards her husband.

Even if she really used that poison needle to poison the victim, there must be evidence to prove that the poison needle was hers...

Inspector Megure and his group looked at the dark-skinned boy in front of them in surprise: "Who is this young man? Brother Mori." Inspector Megure asked Kogoro Mori.

"…His name is Hattori Heiji, and he's an arrogant young detective."

Zhao Lan applauded Uncle Maori in his heart. This summary was so insightful...

"Oh? So it's you, Hattori Heiji. You are the high school son of Hattori Heizo, the current chief of the Osaka Police Department."

Yanyan on the side looked at Hattori Heiji with sparkling eyes. This older brother knows so much, just like Brother Shinichi.

"All the windows in the study are locked from inside the room. If you want to come in from the outside, the only entrance and exit is that door. So the most likely suspect now is the person who holds the key to the room in this house." After listening to Hattori's reasoning, Inspector Megure concluded.

"Isn't it possible that the murderer killed people after we came in?" Zhao Lan couldn't help but express his thoughts.

The direction of her words was very clear, she was just short of directly saying that the murderer was Mrs. Yucun.

Everyone looked at Zhao Lan, and Uncle Mao Li laughed and said, "That's impossible. We are always with Mrs. Tatsumura. She can't have committed a crime."

Conan: "Sister Zhaolan, why do you say that?"

"I'm just saying that there is such a possibility. After all, Hattori-kun also said that it is an instantly lethal poison, isn't it?" Doesn't that mean anyone could be the cause?

Seeing that no one took it seriously, Zhao Lan stopped talking. Only Conan looked at her with a thoughtful expression.

"Then Mrs. Tatsumura, there should be several keys to this study, right?" Inspector Megure looked at Mrs. Tatsumura and asked.

"Uh, no. There are only two keys to this study. One is with me, and the other is with my husband. He usually puts the key in his trouser pocket." Mrs. Damura said, taking out a key from her bag and showing it to everyone.

"Then let me take a look..." Upon hearing this, Inspector Megure touched the deceased's trouser pocket.

A key fell out of the deceased's trouser pocket.

Conan, Hattori, and Inspector Megure were all shocked when they saw the key falling out.

Only Maori Kogoro was still confused. He looked at everyone's expressions and said, "What, what happened...?"

"Don't you understand? The door was locked when we came in. If both keys are here, how did the criminal get in and out? This makes this a locked room, which creates an impossible perfect crime. This is a locked room murder case."

"Hey~ How is this possible..."

When Hattori Heiji saw the shocked expression on Uncle Mori's face, he immediately suspected that the cases he had handled before were probably not his own reasoning.

Well, he is now waiting for this confused uncle to contact Kudo, and they will have another showdown. Thinking of this, Hattori Heiji's eyes were burning with fighting spirit.

Meanwhile, Kudo, who he was thinking about, was suffering from a cold. Not only did he feel that his cold was getting worse, but he also started to have tinnitus in his ears. Now he just wanted to solve the case quickly and go home to have a good sleep.

Zhao Lan curled his lips: What kind of secret room is this? If you want to get the key, there are at least several ways to make a copy...

Hattori looked at Officer Maori and said, "What are you waiting for? The crime should have happened between 3:4 and :. Now it is most important to quickly find out the alibi of the person who may have committed the crime during this period."

"Ah, yes, yes." Inspector Megure laughed awkwardly.

Inspector Megure was angered by Hattori Heiji's arrogant attitude.

Turning around, Zhao Lan saw him saying to Mr. Maori, "Do you want to let an outsider and a young boy show off? I have placed all my hopes on you, the great detective." After saying that, he patted Uncle Maori on the back to cheer him up.

You've asked the wrong person, ask Conan to be quicker. Zhao Lan also saw the level of Uncle Maori's ability to solve cases...

She said that before, she had only heard that Uncle Maori found cats and dogs for people, or caught cheating, but suddenly he became a famous detective...

I'm afraid all those famous cases before were due to this kid Shinichi.

Suddenly, a police officer came over and said to Officer Megure: "Officer, we found that the victim's key ring is a bit unusual. When the key ring is opened, there is tape inside."

When Zhao Lan saw the key ring, he instantly understood how the lady had killed someone.

The couple's key rings were exactly the same. If the lady had placed a poison needle in the key ring and pretended to call for help, it would be entirely possible that she had poisoned the deceased to death.

However, before she could express her guess, the black-skinned detective also saw the key ring.

He had already worked out a whole set of reasoning, that is, by passing a fishing line through the dead man's key ring and then pulling the fishing line out of the door, he could put the key into the dead man's pocket.

The person who can do all this is the father-in-law of the client outside.

He also found fishing line in the trash can outside, and the old man admitted that he was the murderer.

Zhao Lan's eyes widened. She couldn't help but doubt her own guess. Could it be that the lady just wanted to kill someone but didn't have time to do it? She really wasn't good at this kind of thing...

"Conan? Conan? Wake up!!"

"Conan? What's wrong with you?"

Suddenly I heard Xiaolan and Yanyan's anxious voices. I turned around and saw that it was Conan who had fallen down.

Zhao Lan hurried over and touched him. His body was very hot. Was his cold so serious? Zhao Lan saw that he seemed to be in pain, so he gave him a little bit of his supernatural power.

The child was too sensitive and she couldn't do much. This ability might make him feel more comfortable.

Watching Xiaolan borrow a room from the family and send the patient there, Zhaolan called the doctor.
