"You mean, you don't know what you've done?" Nakamura asked in surprise.

"I drank so much that I couldn't remember where I got out of the car and went, I woke up and found myself lying on a lawn, I stopped a taxi in a daze and went home, I couldn't think of anything, even I wondered if I killed someone, every time I thought about it, I was very scared, so when I faced you police, I always refused to tell the truth, I didn't want to get involved, but I was worried that if the murderer was really me....." Ito's eyes widened and his hands trembled.

I looked at Nakamura, and there was no taste in the eyes of either side.

"Do you think Ito is the murderer?" I looked at Watanabe Nakamura in the office and asked.

Watanabe shook his head, "Probably not, I can't imagine a drunk person climbing over a balcony on top of a 26-story building, entering the deceased's home with an air conditioner extending from the floor-to-ceiling windows, and still being able to erase all fingerprints." ”

"Maybe there are all kinds of things in the world, you see a lot of people sleepwalking after they do not remember at all, a few years ago, there was a case, a mother sleepwalked and killed her child, and carefully cleaned up the traces of the crime, but the next day I got up and called the police to arrest the murderer, and it was the section chief who solved the case at that time, and this case was known as the most difficult case in Japan in this century."

"Sleepwalking and drunkenness are two different things, but there's no guarantee that he didn't pretend on purpose, maybe his murderous plot was about to be exposed, so he pretended that he had forgotten everything." Watanabe said.

"But the strange thing is, if Ito is the murderer, why did he invite Shiraishi out for a drink? This doesn't create an alibi for him, and often the secret room killings are not all about creating an alibi for themselves? However, it was through the surveillance of the izakaya that we discovered Ito's suspicion of committing the crime. Nakamura said with a frown.

"Okay, whether he really forgot or pretended, our police pay attention to evidence in handling cases, and what we have to do now is to find out the evidence, as for whether he is the murderer or not, let's judge it with evidence." I said.

The office door suddenly opened, and a head poked in, and we saw that it was Kudo, "I heard that an important suspect has been caught?" How is it going, is there anything I can help with? ”

I glanced at him, stood up, walked past him and out the office door, and paused as I walked past him, "I'm going to work overtime tonight, so I can't invite you to drink." ”

The night sky was soon occupied by sunlight, I looked up, rubbed my eyes, and found that I had slept on the table all night, Ito was still left in the bureau by us, although we did not have direct evidence to accuse him of murder, but with this circumstantial evidence, he did not want to leave my sight easily.

I stood up, stretched my waist, and looked at Nakamura who was sleeping on his back on the chair next door, I really admired this difficult posture that he could sleep so soundly, but this also shows how strong the case is, people of his age are really unbearable, thinking of this I couldn't help sighing, originally for this case, we are all under great pressure, since Kudo came, our pressure is even greater, I can see that not only me, Watanabe and Nakamura and other colleagues in the bureau are working very hard and even desperately into the case, I knew they were all for me, and my fists clenched secretly.

Walking out of the door, there are already a lot of colleagues in the bureau walking back and forth, except for some small things, most of them are running back and forth for this secret room killing, when I passed through a room, through the half-covered door, I suddenly found that the person sleeping in front of the table in the room was Kudo.

I quietly walked in, and found that there were photos of the closed room murder case in front of his desktop, and a blank piece of paper detailed the clues of the case, details, and suspicions, many places were also heavily circled by him with a red pen, I frowned, I didn't expect him to listen to me, or privately investigated the case, too, he was originally such a person, he would not have the slightest hesitation about the case, as if this was his natural enemy, as long as he lived, it was impossible to let the criminal go unpunished.

I looked at his sleeping position, that familiar face, looked at this once very good friend, and said in my heart, I don't feel good, over the years, we have gradually gone farther and farther on different horizons, until we are completely separated, is it really impossible to go back? I sighed.

Seven o'clock in the morning.

Watanabe and I stood in the house next door to Chiyoko, which Ito rented, that is, Kumamoto's house, the room was a little scattered, and the drawers were not closed, which shows that Ito's usual habits are very casual, we searched carefully, and the house did not find anything except messy.

We left the house, left the apartment, came downstairs, I looked at the familiar environment around here, we checked the surveillance of the place where Ito got off the car, the surveillance showed that Ito got out of the car and walked towards the apartment, looking at the pace was very shaky, so that people could not tell whether he was pretending to be or not, he must have been around here, because there was no surveillance in the apartment hall, we had to investigate the surveillance around this area, if we could find Ito's traces, we could figure out where he went on the night of the crime.

Watanabe and I went our separate ways, I went to many stores and didn't find any shadow of Ito from the surveillance, an hour passed in the blink of an eye, and I still didn't make any progress, but I was sweating, Watanabe must not have found it, otherwise he would definitely call me.

The apartment is located in the center of the city, and the surrounding area is very wide, if you look for it like this, it is equivalent to looking for a needle in a haystack, how can you find a trace of a person in this world?

At this time, the phone rang suddenly, I looked down and saw that it was Watanabe calling, I was shocked, could it be that this kid has found Ito's traces?

I picked up the phone and said, "What's wrong, Watanabe, found Ito?" ”

"Oh no, but I suddenly remembered what Ito said at the time, he said that he woke up on a grassy field, although he couldn't remember where that place was, but he came and quickly got a taxi, indicating that the location of the grass was on the side of the road, so the range was greatly shortened, we only need to put the end of the patrol on the grass on the side of the road, and we should be able to find Ito's trace soon." Watanabe's excited voice on the phone was particularly deafening.

I was a little surprised, this really didn't look like a newcomer's idea, I frowned, "It's not something you thought of yourself, say, who told you that." ”

"Uh... I still can't hide it from the section manager, it's Kudo, he just called me to tell me, and he asked me not to tell you that he said it. ”

My brow furrowed even deeper, and then I hung up, "So be it." ”

Kudo's unusual attention to detail made me clench my fists, and I gritted my teeth and stopped being swayed by the thoughts in my head, and began to search for the grass on the side of the road.
