The elementary school students leave school early, and Conan, who is thinking about the progress of the case and the goal of organizing the action, naturally has no intention of playing with the children, so he asks Gray Yuan to take care of them, and sneaks out into the street alone, but he doesn't know what direction to think about for a while. The phone rang, and it was Kudo Shinichi's mobile phone that received a text message, so it was Lan ......

The helmet of the black knight is broken, and there are my fingerprints on that helmet, and sure enough, the horn of the unicorn fairy was done by them, and these two fingerprints were collected at the same time, and a little comparison can lead to the conclusion that Edogawa Conan and Kudo Shinichi are the same person. Conan instantly recalled the scene in the dream where he was caught by Gin, and shook his head, the current situation is not so bad, although Irish is suspicious of him, but he has not received conclusive evidence, the fingerprints on the unicorn fairy belong to Mitsuhiko, no matter what this time his identity will not be revealed. However, it can't be taken lightly, at least Irish knows about the Black Knight case, he knows that Kudo Shinichi appeared at the scene of that case, but at that time, in the internal information of the organization, Kudo Shinichi has been confirmed dead, which means that he may still be exposed, but it is Kudo Shinichi's identity that is exposed, and the organization will not trace down Edogawa Conan's head for the time being. Relieving his nerves, Conan reorganized the existing information, although his identity is not dangerous for the time being, but the policeman who was replaced by Irish is still missing, whether it is to save him or to defeat the organization, Conan must try to find the murderer of this case. And that SD card, as long as you get the memory card full of information about the spy members of the organization, you can grasp the opportunity, and even use it to defeat the organization's sphere of influence in Japan in one fell swoop, and catch the prisoner as soon as possible.

"Drip ...... "......The sound of a car horn came from the side of the road, Conan subconsciously looked back, the familiar look should be Kazama's car, and then the gray plain in the row of seats opened the window, beckoned to him, and after a little thought in his heart, Conan still opened the door and stepped into the car.

"How's it going, Detective? Have you figured out the meaning of 'Tanabata Kyo'? Kazama asks Conan about the progress of the case, after all, this SD card is too important, but before going to investigate the case, the car is driving in the direction of Dr. Agasa's house, and he wants to send Ashbara home first, believing that Mr. Okiya next door can protect her.

"Not yet...... Completely clueless. Conan shook his head, he really didn't think of what the code meant.

"Today is Tanabata, if Tanabata refers to the day, then will Beijing be the location?" Kazama pretended to be talking nonsense casually, but Kazama, who was familiar with the plot, naturally knew that Kyo represented Kyoto and gave Conan some help.

"Kyo ...... That's right, Kyoto! Conan didn't care about Kazama's abnormality at all, Kazama never said a word when he reasoned on weekdays, but today he would say his opinion, and he really helped himself crack the code. Conan couldn't wait to take out his mobile phone, dialed Hattori Heiji, who was far away in Osaka, and hastily introduced the course of the case, Conan asked his own question, "What do you think of when you talk about 'Tanabata Kyoto'?" ”

"The Tanabata Festival at the Landlord Shrine is famous...... If you go to Kyoto today, you can come back on the same day, and you don't have to stay in a hotel at night. He Ye expressed his opinion on the side.

"Even if you don't say it, I won't stay in a hotel, have you forgotten the fire the year before last?"

"Hattori, what's going on with the fire?" Conan on the other end of the phone keenly captured the message in Hattori's words.

"The year before last, there was a fire in Kyoto...... Well, it seems to be the night of Tanabata. Heiji Hattori suddenly remembered that the date of the case was the day of Tanabata, "The hotel where the fire broke out seems to be called 'Vega', and two guests died. ”

"Hattori, can you look more closely into that fire? It's urgent. ”

"Of course!"

Conan, who put down the phone, thought alone, "Fire, do the red circles and letters on the mahjong tiles refer to fire?" Kazama sent Ashbara to the doctor's house and returned to the car, "Detective, where are you going to investigate the case today?" Today is Tanabata, do you have eyebrows? ”

"Rice Flower Library, I'll look up some information."

"Then I'll send you over and wait for you in the car, I don't really like the atmosphere there."

"Okay."

……

The cause of the fire was caused by the tenant on the fifth floor who smoked carelessly, and the escape route happened to be unusable, and a tenant on the sixth floor choked to death by thick smoke, her name is Nanako Motogami, if Kazama is here, it will be remembered, yes, the source of this case is because of this cute girl.

Conan, who ran out of the library, ran into Kazama's car, "Mitaka City, how do you know each other?" ”

Kazama sat in the driver's seat and flipped through his phone for a long time, "I don't know, but it does." He patted the phone in his hand, turned on the navigation function on the map, and hung it next to the dashboard, "Well, it's close." ”

With the navigation of the map, Kazama parked the car near a very ordinary residential building, Conan found the house where Nanako Hongami once lived, and knocked on the door for a long time, but her boyfriend Kosuke Mizutani never came to open the door, "Mr. Mizutani is out." The man who lived next door to them explained to Conan.

With the help of Mori Kogoro's assistant, Conan began to ask the neighbor, "What is the relationship between Mr. Kosuke Mizutani and Miss Nanako Honue?" ”

"It's a romantic relationship. But because of the opposition of their parents, they eloped from Chiba. The year before last, the two of them came to Kyoto for a trip and stayed in that business hotel, but Mizutani went out alone to meet a friend who lived in Kyoto, and during that time, the hotel caught fire, and Nanako died in this way. If she hadn't gone to see that friend, Nanako wouldn't have died. Mr. Mizutani said with tears streaming down his face. ”

"So where is Mr. Mizutani now?"

"I don't know, he hasn't been back for a long time...... Maybe in Chiba! Today is his girlfriend's second anniversary. Just ask her brother. The neighbor got up from the ground and rummaged through the bookcase, "Her brother has been here many times before, saying that if his sister is in trouble, he will go to him for help. Conan saw Kosuke Mizutani's photo, as well as the business card of the deceased's brother.

Sitting back in Kazama's car, "How's it going?" What clues were found? ”

"Let's go and ask the deceased's brother." Before the car started, Conan's cell phone rang, it was Hattori Heiji.

"Kudo, the list of the seven victims you sent is the same as the list of tenants who lived on the 6th floor at the time of the fire, and in addition to that, there are two other people living on the 6th floor."

"Nanako Honjo and Kosuke Mizutani." Conan took the initiative to answer.

"That Mizutani also came to investigate this matter a year ago, and this case must have something to do with the fire two years ago. But what's the connection, if Mr. Mizutani is the murderer, then what is the motive? Miss Ben obviously died in an accident. ”

"Hattori, how many elevators does that hotel have?"

"Elevators? There's only one. ”

"How many people can you carry?"

"The rated capacity of the elevator is 7 people." At this time, several passengers stepped onto the elevator, and the overloaded bell rang, and Hattori Heiji hurriedly squeezed out the elevator, "I understand, Kudo!" ”

"Yes, it is estimated that on the day of the fire, Miss Nanako Hongami had already walked on the elevator."

"Then she was forcibly pushed out by the eighth passenger, so the mahjong tiles represent the elevator hall, and the red circles on the seven cylinders hint at where the passengers were standing at that time."

"The eighth passenger pushed Miss Nanako, who had already stepped onto the elevator, because the elevator overloaded bell rang, and the other six people acquiesced to their actions because they were worried that they would be implicated, so Nanako, who didn't get on the elevator, couldn't escape and died there."

"There shouldn't be anything wrong with reasoning, but I don't know what the letters behind the tiles mean."

"yes, it's strange that the seventh is not a letter but a triangle."
