Do what you think, in order to verify whether your speculation is reasonable, Shiratori Ren Saburo walked to the bookcase in a few steps and pulled the curtain of the bookcase without hesitation.

Looking at the empty bookcase, the corners of Shiratori's mouth couldn't help but curl, "Sure enough! There are no books in this place, just enough to hide from people! ”

"Huh? I didn't pay attention to this bookcase just now, but when I look at it now, there is really a problem! Not to mention that there are no books in a bookcase, and the curtain that covers the bookcase is different from the others, it is dark beige! Shiratori, can you remove those two partitions? ”

"No problem! We're here to help! Officer Sato, you see, it's easy, isn't it? So if the gangster is really a bank robber, he must have investigated the family's routine in advance, and then sneaked into the house before the hostess got up after the man went out, and the evidence was the glass that was cut next to the door and window switches in the hallway, and then hid in this bookcase, waiting for the opportunity to start! As a result, when the hostess came here to pedal the exercise bike according to her own schedule, the murderer who was ambushing behind her accidentally heard her talking to the police on the phone! Afraid that Mrs. Gadai would go to the police station to expose her gangsters, she hesitated for a while and chose to gamble, and suddenly slashed out and killed Masuo Kadai! ”

"I see? If that's the case, Mr. Katsura Masuo also said that his wife said last night that there was a suspicious man near the house. So it's possible that you came to draw the design of the room and understand the habits of the deceased? ”

was followed by the rhythm of Shiratori's reasoning, Sato on the side was obviously persuaded by him, and began to speculate along this line of thought, while Conan, who had studied the place where the window glass was cut with Yuichi before, knew that there was obviously a problem there, and was anxious about how to remind Shiratori Ren Saburo.

Takagi, who has been in the background on the side, may have been inspired by the power of love, and he didn't want to admit defeat in front of Shiratori Ren Saburo, a rival in love, and his IQ was like a divine help, so he actually refuted it.

"Shiratori Police Department! I have a few different opinions! According to your reasoning, the gangsters killed people because they knew that the deceased was talking to the police on the phone and was afraid of being exposed, right? So why did he put the partition of the bookcase back after he had successfully killed someone? Wouldn't it be easy to be caught by the police who arrived after hearing the screams? And the strangest thing is! There are not a few books in this bookcase, but the books in this bookcase next to it are full! It's like being squeezed in on purpose, don't you think it's weird? ”

"This ......"

"That's right! Moreover, according to what you said, the murderer committed the crime according to Mr. Masao's family's schedule, so he must be under the surveillance of Mr. Masao's house for several days before he can completely grasp it! Just last night, do you dare to sneak into the crime based on the observation of yesterday's day? What if Mr. Massuo and Mrs. Masao's schedules were just a special case yesterday? And the most important thing is that we didn't find a single fingerprint around the cut glass, if the gangster really committed the crime by cutting the glass around the window switch, then he either prepared in advance and wore gloves. There are no fingerprints of him on the glass, but there should be fingerprints left by Mrs. Masuo or Mr. Masuo. If he hadn't done the disguise, there would have been unfamiliar fingerprints on the glass except for those of Mr. Masuo and Mrs. Gardai, but the report of the forensic department just now showed that there were no fingerprints on the glass window, what does this mean? ”

"Someone deliberately wiped all the fingerprints off!"

"That's right! So a person who sneaked in after the man left would still deal with all the evidence of the crime so calmly without knowing when the hostess would come out? Isn't what he has to do to hide quickly? So, the White Bird Police Department! Your reasoning doesn't work! Do you understand? ”

After giving Takagi who was reasoning along his lines of thought an appreciative look, Yuichi, who suddenly messed up, immediately stabbed Shiratori's reasoning completely under the foreshadowing of Takagi's previous question.

"Oh? So what does the Yuichi Police Department mean? Did you leave and come back suddenly to tell us about this new discovery in Forensics? While I admit that there are holes in this reasoning of mine, what about you? Ready to give us some reasoning too? You know, we're cops, not detectives! Finally, it's the evidence! Do you understand? ”

Faced with Shiratori's unconvinced run, Yuichi smiled gracefully and took out the photo album he found in Masuo Kayo's room from behind him.

"That's exactly what I'm trying to say! In the final analysis, we police still have to talk about evidence! Since you're still in the reasoning stage, how about taking a look at what I found outside the crime scene? This was found in the room of Mrs. Masuo Kayo, who was just a waste of police resources at your Shiratori Police Department! Mr. Masao, should you come out and explain why your wife circled every picture of you and this person? It doesn't matter if you don't know, I've sent our men to this gentleman, and I'm sure he'll know a little bit about why, you say? ”

"This ...... This is scribbled by insiders...... I stopped her, but ......"

"Oh? Doodled? Mr. Massuo, you're a little bit of a bad guy! It seems that you still have to wait for the other protagonist in these photos to appear before you can be honest! But it doesn't matter! He can't run anyway, so we'll just wait for him here! In this waiting time, let's finish this puzzle game together! About the murder modus operandi of Mrs. Gardai's killing! ”

"What? Youyi Police Department! You already get the idea? ”

"Of course! Don't you think it's strange when you look at the corpse of Mrs. Gardet? ”

"What's weird?"

"The knife that killed her! Ordinary people kill people, whether they are slashed from the top down or stabbed from the bottom up, the knife is inserted vertically into the corpse, but what about the knife that killed Mrs. Gardai? It's horizontally! If the murderer sneaks up from behind, he will never be able to insert the knife horizontally into his body, but if he stands next to him and wields the knife, it is impossible for Mrs. Gardai not to see him, as for him to subdue Mrs. Gardai after subduing him, pressing Mrs. Gardai with his knee or something, and then swinging the knife from the side, then Mrs. Gardai will definitely struggle, and there will be a large area of sweat stains on the floor near this exercise bike, so we might as well boldly assume that if this murderer did not have it at all? This knife flew from Mrs. Gardai's back and killed her directly? ”

In the face of Yuichi's unconventional reasoning, Sato, Takagi and others who were standing around him all looked at each other.
