"The deceased, Masaji Hirota, male, 61 years old, was a professor at Nanyang University. The cause of death was a severe blow to the head, preliminary judgment! The murder weapon is this! ”

"Is this a trophy ornament? Scan the fingerprints on this! See if you find anything? ”

"Yes! Officer Henggou! ”

"This room looks a little cluttered! Bookshelves and telephone cabinets were all over the place, and there were all these messy chess, and the weirdest thing was that the only key in the room was scattered around the room with the books, just below the notebook! The door and windows of the room are locked, so maybe it was an accident? When Professor Hirota climbed up to the bookshelf to get something, he accidentally pulled the bookshelf down, and he fell backwards with the bookshelf, and he hit the trophy that fell before him in the back of his head, and due to gravity and inertia, this trophy became the murderer who killed him! After sending his men down to continue collecting strong evidence, the Henggou police officer, who was squatting on the ground, looked at everything in front of him and began to reason.

"But Officer Henggou may have been murdered! These scenes were just deliberately disguised as accidents! ”

"Huh? Are you the kid from Mr. Maori's family? How did you end up here? What about Mr. Maori? Hearing these words that suddenly overturned his reasoning, Officer Henggou did not get angry, but looked at the source of the voice with longing, because he had always believed that one person was poor in skills and three people were wise. However, when he saw who was speaking, he had an even bigger surprise.

"Hahaha! Sorry officer! This is my relative's child, temporarily fostered at the Maori Detective's house, I brought him out today, and Mr. Maori did not follow! Dr. Asasa, who was afraid of Conan's reasoning, immediately went to explain, but Officer Yokogou was not as easy to deal with as he thought.

"The Maori detective isn't here, and this little ghost who follows the Maori detective shouldn't be bad, right? After all, a big god like Mr. Maori, even his followers are a small god! Come on, come on, Maori detective imp! Don't be afraid! Get your thoughts out there! If I help my uncle, I'll be rewarded! ”

"Great God? I'm the real god, right? Where is there a little bit of great brilliance in Uncle Maori's scumbag who drinks and gambles and watches beautiful women? He's just my vest to hide my dazzling brilliance, and I'm the low-key god, you know? Although I complained wildly about Officer Henggou's remarks in my heart, I was so dissatisfied that I exploded. But Conan, who couldn't resist the temptation to solve the case, couldn't help but show off his superior reasoning IQ.

"Officer Henggou, look! The phone cabinet fell with the bookshelf! The books on the shelves were all spilled on the floor, but the strange thing was this! As he spoke, Conan picked up a book with a phone under it.

"Phone?"

"That's right! Phone! The books were scattered, but the telephone microphone that fell from the telephone cabinet did not fall out, but was firmly buckled on the phone, Officer Henggou! Don't you think it's weird? ”

"I see! Someone came in and killed Professor Hirota, and then knocked down the bookcase, turned the phone upside down, and pressed the book on the phone to disguise it, which is indeed a sign of artificial arrangement. If you look at it this way, this is a case of murder in a closed room! ”

"Indeed! Moreover, the prisoner arranged a telephone so deliberately that I think this telephone must have played a decisive role in the process of his crime, so that he had to arrange the telephone like this! Maybe we should take a good look at this call! Conan, who saw that Officer Henggou recognized his judgment, seemed to be encouraged, and did not hesitate to open Officer Henggou again, pointing out a clear way.

"Makes sense! Let's take a good look at this mysterious call! Hey? Is there a recording? 13 phone calls? That's a bit weird! Mrs. Hirota, is there any suspicious person visiting the professor tonight? Officer Yokomi, who was instructed by Conan, immediately reversed his previous inferences and began to judge the case as a homicide case.

"Huh! Including him, it seems that three or four people came! ”

Following Mrs. Hirota's fingers, Officer Yokozo set his eyes on Dr. Asasa, who was eating melons on the side, and Dr. Asasa immediately jumped up.

"Huh? I? I'm just here to get back the disk that my friend accidentally gave to Professor Hirota, and Mrs. Hirota was already home when I came! How could I possibly commit murder? Besides, no one committed murder and brought two children out, right? ”

"Crackling! Cracking sound! ”

"Gone! All the disks are gone! Looks like the data on the computer may have been washed out as well! Just as the doctor was nervous and explained that he had no motive to kill and that he had committed the crime, Xiao Ai, who had been disappearing just now, suddenly opened his mouth to show his sense of existence.

"Who is this girl?"

"Hahaha! This is also the child of my relative's family! Anyway, this matter has nothing to do with me! ”

"Huh! Is it? Glancing at Conan, who was bowing his head and contemplating beside him, and then at Xiao Ai, who had just been picked up by Dr. Asasa from the computer, Officer Yokozo found that he couldn't believe Dr. Asasa's justification for taking the child out to kill people, this is not an ordinary child, right? How do you feel more powerful than adults!

Ignoring the already messy police officer, Conan and Xiao Ai, who found that the disk had disappeared, got together for the first time.

"The disk is missing? Could it be that they have already put the disk ......"

"Possibly! After all, there are records in the organization of the loss of the disk filled with drug information and the records of me mailing things to my sister during the same period! I didn't defect before, so no one checked it, and now that I'm gone, I'm afraid these records will be turned out! ”

"I see! It's not hard to find them here after rummaging through your records! In that case......"

"The organization who infiltrated to find the disk happened to be bumped into by Professor Hirota, and in order to keep it a secret, he killed him, which is really embarrassing!"

"Nope! It's too early to make an assertion! Based on my past experience, as long as I encounter a case, it will not be solved so easily! And this time it's a closed room homicide, I don't think that such a terrible organization is not in a hurry to leave after killing someone, but risking being found again to set up this kind of venue! If it were them, a bomb would have solved here, right? I've learned how they do it, and killing people is child's play! Remembering the scene where he was almost killed when he first came into contact with the black-clad organization, Conan couldn't help but grit his teeth fiercely.

"You have a point! Then let's listen to the recording first! ”

While Conan and Xiao Ai were muttering secretly, the recovered officer Yokomizo had already begun to continue to ask Mrs. Hirota about the people who had come to visit.

"You met the first person to visit, Miss? Come on, go and bring the small loss here! ”

"Who else? Shirakura and Morioka? Bring it too! If you don't know, listen to the recording! ”

As one recording after another passed, the caller also confirmed that there were only these few people, and just when Officer Henggou pressed the last recording, Conan and Xiao Ai, who heard the familiar voice, couldn't help but look at each other.

"This breath! This sound! You can't go wrong! It's vodka! ”

"Hello...... It's dark here...... Life...... I would like to explain to you...... Our new insurance product ...... Could you please dial a moment...... Come out? ”

"Pull the insurance? It seems that this thirteenth call is useless! Then ask about the loss first, Shirakura and Morioka! After listening to the last phone call, Officer Yokogou turned off the recording indifferently, but Conan and Xiao Ai, who knew the inside story, knew that a big crisis in their lives might be coming.
