"So, the person who has been wearing a mask and hat to disguise himself in the surveillance is Ito." Nakamura said.

"Yes, Kumamoto hasn't been back since he rented the house to Ito, so that person is undoubtedly Ito, and Ito was near Shibazono Apartment at seven o'clock on the night of the crime."

"So Ito is suspected of committing a major crime, but I don't understand why he disguised himself like that. And swaggering into the house under surveillance, did he naively think that we would focus all our attention on Kumamoto? ”

"I don't know about this, but if he really committed the crime, then how did he get into Chiyoko Suzuki's house on the night of the crime?"

Nakamura frowned too, and whenever he was in distress, I felt a little less hair on the top of his head.

"I think we'll have to go back to the scene of the crime" I looked at Nakamura, who nodded and started the throttle.

We came to Chiyoko's house and took out the key to open the door, because we needed to change the lock of Chiyoko's house to solve the case, the key was only in the hands of a few of our policemen, the room was very dim, Nakamura turned on the light, looking at the messy living room in front of me, my heart was inexplicably painful.

"What we can be sure of is that no one entered or exited this door on the night of the crime, which means that the murderer must have entered this house through other means." Nakamura said, looking out the window, "only through the outside." ”

"Let's go to the balcony and see it again." I said that we had suspected that the murderer entered through the balcony, but we surveyed at the time, and the balconies of each household were very far away from each other, and the designer must have been worried about theft between the residents at first, so the balconies were separated by the ceiling window of the living room, so we ruled out the possibility that the murderer entered the scene through the balcony.

But when I stood on the balcony and poked my head into the 2607 Kumamoto house next door (Chiyoko's house is 2606, my house is 2605), my eyes widened in surprise, and Nakamura poked his head out curiously, and his body slammed instantly.

Because through the dazzling glow, we could see the white air conditioner under the floor-to-ceiling window, and because it was night, none of us noticed, and at this time my eyes lit up with a sharp light, because I already knew how Ito entered Chiyoko's house, he must have used this air conditioner as a springboard to enter Chiyoko's balcony, and then set up this cruel secret room murder with his own hands.

"Bang", the lights in the room came on, and the white light shone on Ito's bleak face, and at this moment he sat in the interrogation room and looked around uneasily, his hands clenched, and he kept panting.

Nakamura and I walked into the interrogation room and sat across from Ito, Nakamura had a pen in his hand, his eyes looked very gloomy under the gloom of light, and he stared at Ito as if he wanted to see through his body.

"I didn't kill anyone, I didn't kill people!" Ito seemed to be a thief, and he shouted anxiously before we could speak.

"May I ask where you were on the night of the 15th?" I asked.

"Didn't I say that I was drinking with Shiraishi at an izakaya? It's just drinking. ”

"But according to our investigation, you left the izakaya at 7 o'clock and took a taxi, and the place where you got off was less than 500 meters from the Shibaen apartment, what are you going to do there?"

"I... I.." Ito's expression showed obvious panic, as if he had been poked in the underbelly.

"And we also found out that you rented the house next door to the deceased, and you still wore masks, sunglasses and hats when you went in and out, how can this be explained?"

Ito's face became more and more pale, because of the reaction when his hidden things were discovered one by one.

"And based on the threatening text message you sent to Chiyoko before, it seems that you killed Miss Suzuki, right, in addition to you and Miss Suzuki, the people who know the content of this text message have an alibi, so you killed it, right? I was right, Mr. Ito, Nagawa, when he entered Miss Suzuki's house from his balcony through the air conditioner, and then killed his ex-wife and his own son with his own hands, and then returned to his house after processing the scene. "I stared at Ito as if a sword was about to burst out of my eyes.

"No... It's not like that, it's not like that. Ito clenched his hands.

"If it's not you, then tell us the truth!" Nakamura stood up and slammed his hands on the table, "It's your former wife and your son lying in the morgue!" Doesn't your heart hurt? Because I am also a husband and a father, and I also have a son, although I am a police officer, I will drink when I am fine, I will secretly bet on polo behind my wife's back, and I will watch A/movies when I am bored, but even if I am useless as a jerk, I will not harm my son, I know that no matter how vicious a person is, it is difficult to kill his own child with his own hands, or strangle him to death in such a cruel way. This is an experience that only fathers can have, and I believe that you are not the murderer. ”

"But you didn't cooperate with our police from the beginning, and you lied from the beginning, you said that you haven't contacted Miss Suzuki recently, but after our investigation, it shows that you have been harassing her, you said that you have been at home at the night of the crime, but the truth is that you drank in an izakaya, and after drinking, you went to the apartment where the crime occurred, and you also concealed that you lived next door to Miss Suzuki, if you are really not the murderer, then cooperate with our police from now on, I know that you must not want to have anything to do with this matter, but you are a father, don't you want to catch the murderer? Don't you want to give your son and your ex-wife an explanation? After all, that's also the wife who has lived for many years, can you be like a man! Don't be secretive, okay? Nakamura stood still gasping for breath as he finished speaking, and Ito was already stunned by the fright, and then he spread out on his chair like a deflated ball.

Nakamura sat back in his seat, I turned my head to look at this middle-aged man, I have worked with him for so many years, I always thought that he was just a mediocre middle-aged man, this is the first time I have seen him so explosive, I can't help but be a little surprised and surprised.

Ito sighed, "Hey, you're right, I'm not a father, not a husband, not even a man, I do harass Chiyoko all the time, and even sent her a text message like that one night, but I miss Shota too much, after the divorce, after losing them, I felt what regret is, but because I know what a bastard I have done, I don't ask Chiyoko for forgiveness, I just hope to meet Shota and meet my son." ”

"But Chiyoko didn't allow it, she refused any of my requests, didn't give me a chance, and even called the police later, the police's repeated intervention still couldn't make me die, and finally the police gave me a warning, if I harassed their mother and son again, they would forcibly detain me, I had to promise not to harass me again in the future, but how could I really agree? I later came up with a solution.,It's to secretly rent the house next door to Chiyoko's house.,So you can see Shota often.,In order not to be discovered by Chiyoko.,So every time I go in and out, I wear sunglasses and a mask.,Even I put on a hat on a hot day.,In order not to be discovered.,You came not long after I got home that morning.,I thought you found out and I was harassing Chiyoko.,But you told me that Chiyoko and Shota's death.。 ”

I narrowed my eyes, which would explain Ito's wary expression when he first saw Chiyoko, and why he was disguising himself.

"Then why did you go to the Zhiyuan Apartment after drinking on the 15th?"

"That day, because I knew the news of the power outage in advance, I made an early appointment with Shiraishi to drink, but after drinking, I was eager to see Shota and wanted to talk to him, so I took a taxi to Shibaon Apartment with the strength of the drink" Ito suddenly paused, lowered his head and stopped talking.

"So since you didn't kill the person, where did you go after you got out of the car?" Nakamura asked.

Ito looked up at us in despair, "I forgot, I don't remember anything, I drank so much that I wasn't sure if I killed someone." ”

"What?" Nakamura and I looked up, surprise on our faces at the same time.
