Although the clues to crack the alibi were found, there is no evidence yet to prove that the murderer is Maiko Kawara. Mo Xian and Conan looked at each other and said to him with a smile, "Hey, I might know where the evidence will be hidden."

"I know how the murderer got out of the secret room," Conan replied like a grown-up.

"So the problem now is—" Before Mo Xian could finish his sentence, he was interrupted by Xiao Lan who came out from behind him at some point, "Mo, Conan, what are you doing?"

"Ah, hahaha," Mo Xian and the two pretended like nothing had happened reflexively, and persisted for a few seconds under Xiaolan's firm gaze. Conan couldn't stand it and said obediently, "I You're helping Sister Mo solve the case, aren't you, Sister Mo?"

Mo Xian nodded like a chicken pecking rice, "Yes, yes, Conan is very useful."

"Really?" It seems that because of Mo Xian's relationship, Xiao Lan temporarily accepted this explanation, "Then don't make trouble for Mo, Conan."

After Xiaolan went back to the living room, the two breathed a sigh of relief, chatted in the bathroom for a while, and after clearing up all the cases, they began to think hard about how to tell the reasoning to the adults outside.

"Just go ahead and talk," Conan said in a puzzled tone.

Mo Xian stared at his glasses and pointed at himself, "Me? I'm just a high school student, will they believe it?"

"Don't be afraid, sister," Conan said solemnly, "There is a famous detective who is also a high school student at Mi Hua's side, his name is Kudo Shinichi, so if you tell the story, elder sister, it won't surprise the grown-ups."

[Is it really okay to praise yourself like this? ] The audience couldn’t help complaining, [I’ve been wanting to say this for a long time, did he say it himself?Too narcissistic! ] [Actually,] Yan Li was thinking about typing on the keyboard, [I probably also know how this secret room was made, well, this is actually a very simple secret room murder case, I can reason, but unfortunately there is no evidence . ] [No spoilers! ] Just like watching a movie, the audience who watched the live broadcast also refused to spoil the matter. It was different from Sherlock Holmes's battle of wits and courage at that time. , the two contain each other, but they are the best allies, [Anyway, Momo can't break it and Conan is here, so we don't need it. ] [We just quietly watched the podcaster and Conan pretending to be aggressive. [Manually clever]] "But," Mo Xian was still hesitating, "After all, we were brought here by Uncle Mao Li, if I broke the case, it would be bad for Uncle, right?"

"Ah, ah, ah," Conan took her hand and wanted to drag her out, "Didn't you just stay in the Maori office for a summer vacation? What kind of influence will it have?"

Mo Xian was about to say something to decline, when he heard Police Officer Mumu's words in the living room, "Excuse me, both of you, we still have to invite you to the police station for a while."

"Wait a minute." Hearing this, Mo Xian no longer hesitated. Both her and Conan's reasoning was based on the fact that the evidence had not been destroyed. If Maiko Kawara was put back, the evidence might never be found again.

In the eyes of several police officers, suspects, Uncle Mao Li, and Xiao Lan, Mo Xian walked out of the bathroom, stretched out his cold right hand, and smiled innocently, "I'm sorry, but I seem to have found this in the bathtub."

What she held in her hand was a small, blood-colored ice cube.

Put ice cubes on the body to freeze it, and add cold water. When the police check the temperature and stiffness of the dead body, they will misjudge the time of death. Of course, professional forensic doctors will also dissect the stomach to check the digestion of its stomach contents. The degree and the temperature of the liver, there will be no time error, but don't forget that the police originally defined it as suicide, and during the time when the body was transported to the morgue for autopsy, the murderer could destroy the evidence early.

"That's why," the people present understood what was going on when they saw the ice. "The murderer wanted to use ice water to delay the time of death, which proves that the murderer was the one who had the alibi," Mouri said to Maiko Kawara. , "The murderer is you!"

"Actually, I felt strange when I was in the supermarket." Mo Xian handed the ice cubes in his hand to the police officer who collected the evidence. I'm really hungry, and I don't need to put so much in the shopping cart. When I heard you said that you were going to Mihua to meet a friend, I knew that because the friend was away temporarily, you couldn't have sufficient proof of absence It proves that you were in Mihua at the time. In desperation, you had no choice but to find a supermarket at random, hoping that the surveillance cameras could take pictures of you. For this reason, you not only wandered around the supermarket for a while, but also bumped into Conan on purpose, so that the witnesses and evidences are complete. gone."

[No wonder why I feel weird,] The melon-eating audience suddenly realized, [It turned out that Mo Xian paid special attention to the pile of things he bought before going out, because he remembered the food in Maiko Kawara's shopping cart. ] [I give full marks to this speculation, and the evidence can be presented next! ] [I can also buy it and not eat it,] The stubborn barrage insists on raising an argument, [This does not prove anything. ] [In front, let me ask you, where to buy food is not enough, you have to go to buy rice crackers that take more than an hour's drive, and you can buy so much as soon as you buy it? ] While the barrage was arguing endlessly, Police Officer Mumu scratched the back of his head and asked, "But how did she get out of the secret room?"

Mo Xian evoked a mischievous smile, "Conan, come and explain to Officer Mumu."

Conan stood up helplessly, and said innocently, "My sister told me that just now."

That's right, this secret room technique is probably the simplest of all secret room murder techniques. Simply use tools to lock the door from the outside. Anyone who has watched a few episodes of Conan will have the impression that the thread is glued to the door latch with tape, and the The thread passes through the crack of the door, and pulling the thread outside will lock the door latch, and then pull it harder, and the tape will be pulled off, leaving no clues except for the sticky tactile sensation on the door lock.

"Of course, this really doesn't prove anything." Before Maiko Kawara could speak, Mo Xian blocked her words, "Anyone can do it, but there is one thing they can't, and that is your shoes, Ms. Kawara. "

Everyone present looked at her black flat shoes.

"In the bathroom, Conan found a little bit of blood that was blocked by something," Mo Xian said bluntly, "I guess, maybe the blood was splashed on the murderer's shoes, and after you rinsed it with water, you hurried to Mihua , Thinking about it, it’s too late to go back to the room to change a pair of new shoes. Officer Mumu, if you do a blood test on her shoes, you will definitely be able to respond. Moreover, if you think the blood test is too troublesome, you can also search the trash can downstairs , I noticed that one end of the bathtub is placed under the blinds, and the blinds have new marks that have been folded. Is blood splattered on the blades of the blinds, and you only noticed it when you put the window down? Worried that the blood stains will make others notice this in advance The room is wrong, so use the handkerchief or paper towel you carry with you to wipe it? You must dispose of the bloody things immediately, I think there may be trash cans downstairs."

Officer Takagi and Officer Megure made eye contact, and they were about to take people down, but was stopped by Maiko Kawahara, she smiled softly, "I didn't expect that the body was found so early, I thought the ice cubes were packed Not enough, now it seems, is too much."

"There's no need to go," she said, "because, when you turn over that trash can, you'll find the handkerchief I threw in there, still stained with Mr. Tsuchiya's blood."

With a short alarm, Mrs. Tsuchiya covered her mouth, and Police Officer Mumu sighed, "Why bother, Ms. Kawara, it's been a year."

"I thought so too at first," Maiko Kawahara sat on the gray sofa with her head lowered and clasped her hands, "My sister has always had a serious heart attack. I can't say much about this kind of thing except for a coincidence. What are you talking about, but," she raised her head abruptly, "if all this is not a coincidence!" She turned her gaze to Mrs. Tsuchiya, "You should also know, Mrs. Tsuchiya."

Mrs. Tsuchiya covered her mouth, avoiding Kawara's sharp gaze, and nodded silently, "Yes," she said, taking a deep breath and leaning on Brother Tsuchiya unsteadily, "We have been to each other long before we separated. Before that incident, he had actually been in close contact with a woman, but after the car accident, that woman seemed to have disappeared, so I knew she was your sister, Chikako Kawahara."

It turns out that before Tsuchiya bumped into Kawara's sister, they had rekindled their old relationship for a while, because Tsuchiya wanted to separate from the obsessed Kawahara Chikako, but she threatened to tell his wife, so she became murderous and deliberately pretended to bump into Kawahara. She scared her to death.Knowing everything in her sister's diary in the old house, Maiko Kawara would want to avenge her.

This murder case in a secret room came to an end in this way, and the ending was embarrassing. It stole Kogoro Mouri's limelight, and Mo Xian felt very embarrassed. Fortunately, police officer Mu Mu thought she was trained by Mouri, so he looked at Kogoro Moori differently. , making Mo Xian and Conan dumbfounded.

That's fine, she's just a passer-by after all, and Uncle Mao Li still has to live on.

"Dad," after Police Officer Meguro escorted Maiko Kawara away, Xiaolan sat in the co-pilot, fastened her seat belt, and asked expectantly, "I promised to have a big dinner tonight, Dad!"

[No way! ] The audience who had just breathed a sigh of relief after solving the case raised their hearts again, [Again? ]
