"Aha! Officer Shiratori, congratulations on your promotion! That's great! I'm jealous of the rise so fast! If you can, how about you put me on the list of bride candidates? ”

Sato, who felt that the atmosphere was a little bad, immediately gaged and chatted with Shiratori, wanting to relieve the tense atmosphere. But Takagi, who has already planted a deep love for Sato, has obviously entered the point of being obsessed with the authorities, and after hearing Sato's joking words, he was directly petrified in place.

"Could it be...... Could it be that the person Sato likes is ...... Is it a white bird? Thinking of Yumi and what he said secretly, Takagi couldn't help but think about it in despair.

Just when he was stunned, Shiratori on the other side had already begun to show his talent and explain his reasoning.

"You heard her screaming on the phone, didn't you?"

"That's right!"

Sato, who was being watched by Shiratori, thought for a moment and nodded in confirmation.

"Usually thieves don't attack the person talking on the phone, but they run away when they are seen or when they scream loudly. And isn't the deceased going to the Metropolitan Police Department to testify today? ”

"That's right! She said she wanted to talk to her husband about the bank robbery......"

"Sure enough, did the deceased reveal that she was talking to the police?"

"Yes! When Takagi answered the phone, she said that it was the police last night! ”

"That's right! The gangsters didn't want the deceased to talk to the police more, so they killed her while talking on the phone! So I decided it wasn't the thieves who came in, but the two bank robbers, so how could they have the time to loot the valuable stuff in the other rooms? Leaving in a hurry is the right choice, right? ”

"Makes sense! What Officer Shiratori said makes sense! By the way, the insider said something about foreigners last night......"

"That's right! Madame Zun must be trying to tell us about the characteristics of the gangsters! Takagi! Contact the Special Search Headquarters! Say that one of the gangsters is a foreigner! ”

"Oh! Good ......"

Just when Shiratori was about to identify the suspect because of Katsura Masuo's prompt, Yuichi, who had finally seen the scene, shook his head and walked out of the living room, probably out of police duty, he still couldn't accept this kind of competition with a human life as a stake, and after a little contemplation, he opened his mouth to prompt.

"Shiratori! Have you ever wondered! There is only about a meter of space behind the exercise bike, and there is no door in the back, why would Mrs. Zengwei be attacked from behind when she was halfway through riding the exercise bike! And the knife stuck in Mrs. Massuo's back, don't you think it's strange? Think about it before you make up your mind! As a criminal police officer, no matter what you do, you must talk about evidence, and don't let some people with ulterior motives sway your thinking! ”

After saying these tips, it didn't matter if Shiratori, who was standing in the living room, heard these words, and Yuichi stepped out of the living room. Since he can't let others search the room at will, he will go on his own.

No matter how he felt, he felt that Katsura Masuo was suspicious, and all his actions today were abnormal. Judging from some of the photos in the living room and the performance of the hostess Masuo Kashiro, Masuo Katsuzo and his wife are not as close as he appears to be now, so why should he pretend to be so sad? Maybe this is of course in a corner and wants the answer he wants. There's nothing to look at in the living room anymore, and he probably already understands the basic routines, so leave it to Shiratori and them if you leave it behind, not to mention that Conan is there. If only Conan could solve this case and slap the somewhat arrogant Shiratori Ren Saburo!

Thinking of the mess, Yuichi stared at the severed glass window in the hallway for a moment before striding towards the stairs on the second floor.

"It's a bedroom! Based on the messy bed and the smell of smoke in the room, it can be determined that this is Katsura Masao's room! There is not a single lady's supplies, they are all some financial magazines, it seems that he and his wife slept in separate rooms! This Massuo Katsura is really acting! Forget it, nothing useful information! Let's get out of here! ”

"This room...... Bah! What a strong perfume smell! There are a lot of cosmetics too! The wallpaper of the room is also arranged in pink, and there is a big bear hugging in the corner, so it seems that this is the room of Masuo Kayo! Will there be anything interesting in her room? Cosmetics...... Pocket...... Clothes...... Photo album! Hey? This album is actually full of Mr. Katsura Masuo and his friends and clients! Isn't it an album of his own album? What do these people who circle with water-based pens mean? Is this a death message that Masuo Kayo didn't have time to talk to us? What is she trying to express? ”

"Uh-huh! These circled photos are actually photos of Mr. Masuo Katsuzo and a stranger, combined with Masuo Katsurazo's series of reactions today! Maybe what Kayo Masuo wants to tell us is that the two people she has captive are murderers! I remember that in the transcript written by Takagi, it was written that the kidnappers had kidnapped Masuo Kayo at that time, maybe she had lived with Masuo Katsura for so many years, and she recognized this as a familiar figure at the time, and Masuo Katsura really had a problem! Hum! With this album, I see how you quibble! I'll wait until I find the other person in this picture and confront you. Shiratori Ren Saburo, still want to fight me? I'll let you see what is the experience of the old criminal policeman! ”

Finding what he wanted, Yuichi didn't continue to stay on the second floor, and hurriedly went downstairs and asked the two policemen who were guarding outside to take a photo to track down the suspect who was circled by Ms. Masuo Kayo along with Katsura Masao, and he himself turned around again and went back to the living room, after all, that was where the case was solved. He's going to ask Katsura Masuo about this album.

At the same time, in the living room on the first floor, after Yuichi left, Shiratori Ren Saburo, who had no one to refute, should have taken advantage of the victory to pursue and follow his reasoning to defeat the Great Demon King Yuichi in one fell swoop, but Shiratori, who couldn't help but think of Yuichi's meaningful reminder before leaving, actually hesitated after pondering for a long time.

I hate to admit it, but what that nasty guy said makes sense. The deceased should have been attacked from behind, but there was no room for the perpetrator behind her. If the murderer attacks from behind the deceased, he will definitely be found by the deceased, so that the deceased will definitely flee from the vicinity of the exercise bike and will not die next to the exercise bike.

So I had to find a place where the murderer could hide, and where? Hey! Maybe!

Seeing the two bookcases standing side by side in the corner behind the exercise bike, Shiratori suddenly walked over, tore open the curtain on the bookcase, and carefully studied the bookcase, if the gangster wanted to commit murder. Remove the partition in the middle, and this wardrobe is simply the best place to hide criminals.
