"Haven't finished eating yet? I'll take you downstairs for a casual bite to eat. I said.

"How can this be, don't bother you." She hurriedly refused.

"It's okay, I've been taking care of your sister before, and I think she wants me to do the same." I say.

Yuhui no longer insisted, nodded and followed me downstairs, she and I randomly found a nearby restaurant to sit down, the dishes were quickly served, we all lowered our heads and ate quietly, I quietly looked at Yuhui, Yuhui ate very slowly, I could see that I was absent-minded, maybe still immersed in grief.

I suddenly remembered that I had never eaten with Chiyoko, and looking at Tomoe's face that was similar to Chiyoko's, my heart tingled more and more as if I was tormented, and I blinked my eyes and exhaled a few hard breaths, trying to calm my mind.

After eating a few bites of food, Yuhui stopped the chopsticks, raised the pair of snowy eyes and looked around at the environment outside the window, her eyes were empty and people couldn't help but feel sad, she suddenly smiled, but this smile couldn't bring people a little warmth, "It turns out that my sister lived in such a place before her death, so prosperous and beautiful, I have never been here before as a younger sister." ”

"Do you have a bad relationship? Oh sorry, I shouldn't have asked such a question. ”

"It's okay." She smiled, "It's true that our sisterhood is not good, but it should be said that our whole family has a bad relationship with my sister." ”

"How so?" I asked.

Youhui blinked her long and narrow eyelashes, like a butterfly fluttering its slender wings, "Because due to the early death of my father, our family only relies on my mother to earn money to support the family, and we can't afford to let all the children go to school financially, except for me and my sister, we also have an older brother, so my mother let me and my sister drop out of school, and let my brother go to school alone, I have poor academic performance, and I have no interest in learning, so I have no opinion, but my sister is different, she has excellent grades, very studious, and her personality is the same as her mother, very strong, She fell out with her mother, ran away from home, entered a strange city alone, worked her own, heard her brother say that she was studying by herself while working, and her brother often called her sister for her living expenses, but I heard that my sister did not accept it, and after my sister left, my mother was also angry and sick, and I was also very angry about my sister's behavior, no matter how it was our mother, how could she be so angry with my mother, and then our family basically broke off contact with my sister, and then our family suffered a major blow again, and my brother suddenly had a car accident, My mother was also unable to work because she was old, and I was the only one left in the house, but since that time my sister has sent back a large sum of money every month, which is enough for all our family expenses. ”

"It's never been interrupted to send money, has it?" I asked.

"Hmm." Youhui nodded, "Mother knows that my sister is doing well and is relieved, I know that my mother still has a sister in her heart, and so do I, but there seems to be an invisible barrier between us and my sister, we have not reconciled until now that my sister has died, the news of my sister's death is like a thunderbolt, my mother was hospitalized all of a sudden, I am also very sad and regretful, I have seen the photos of Zhengtai, what a lovely child, the murderer is really too cruel, why is such a cruel murderer still not caught?" ”

My heart shook, and I silently clenched my fist.

"I think our family is cursed by something, my father, brother, and sister have left one after another, and only me is left." Tomoe blinked her empty eyes and said in a low voice.

"Don't think about it so much, everything will be fine."

"Can you catch my sister's killer?" Tomoe suddenly raised her head and looked me in the eye.

"Don't worry, I will."

"Even if you give your own life?"

"What... What the? ”

"Oh, I just suddenly thought that it seems that the police in the TV series said that, no matter what, they have to catch the murderer, and they will not hesitate to pay for their lives." Tomoe blinked and smiled wryly, "I'm sorry, I said the wrong thing." ”

"It's fine." I lowered my eyes and fell silent as I watched the sparkling rice in the bowl.

May 30, 2 p.m

Today is the fifteenth day of the murder, the last day of the month, and the last date I promised the police department, no matter how much we investigated, there was no progress in the case these days, so Watanabe Nakamura and Kudo and the four of us returned to the scene of the murder, which is Chiyoko's house, next door to me.

We stood on top of the carpet where the crime occurred, although there was not much left of the carpet in front of us and the fire, and there were many numbers marked on the ground, and small signs were placed to remember what had been placed.

And the most striking thing was the two large humanoid markers on the ground, as if two sharp swords were stuck in my heart, making me breathless.

"The pressure is really getting bigger and bigger." Watanabe sighed.

"There's no way, because the citizens are becoming more and more suspicious of whether the police can solve the case, after all, the crime occurred in the center of the city, and there was a closed room murder case in this busy road, and a pair of orphans and widows died, which is really shocking." Nakamura said.

"But I really don't have any ideas, right now." Watanabe sighed again.

"Have you found out all the surrounding relationships of the deceased?" Kudo asked.

"Checked, there is nothing wrong, but I feel a little strange in the deceased's home." Watanabe said.

"What's weird?" Nakamura asked.

"The deceased's father and brother both died in accidents, and now the deceased himself has suffered tragic misfortune, leaving only his mother and the deceased's sister in the family."

"You mean to suspect that the deceased's mother or sister was the murderer?"

"It's impossible for the deceased's mother to be so old, I think her sister Yue Suzuki should be suspicious, after all, all three people in the family have had accidents, which is too strange."

I couldn't help but think of Tomoe, a woman who looks very similar to Chiyoko.

"But the deceased's sister was staying at home at the time of the crime, and she was not in Osaka at all." Nakamura said.

"But she didn't have an alibi, wasn't she out walking alone that night?"

"But someone in the factory saw Yuhui leave the factory at five o'clock on the night of the crime, even if she left the factory and rushed to Osaka non-stop, it would definitely be too late, it would take at least five hours, she arrived in Osaka at ten o'clock, and the case of the deceased's brother and father was very clear, it was a simple accident, the father died of a machine failure, the brother died in a car accident, and the driver of the car happened to quarrel with his wife at that time, and he didn't pay attention to the person in front of him for a while."

"Well, then I don't have any other ideas." Watanabe waved his hand.

There was silence in the room, and my eyes fell on Kudo, a man with amazing powers of observation, who was standing in front of the floor-to-ceiling window, looking at the broken splinter in the window.

I walked up behind him and looked at the big gap.

"This," Kudo said silently.

"What's wrong?" I say.

"I think there's something wrong with it."

"Why?"

"The murderer must have meant to cause this, otherwise he wouldn't have had to."

"Maybe it's to disrupt the police."

"No, if it's really for this, it's completely worth the loss, because the murderer set fire to the scene, and the white smoke ignited at the scene could easily attract the attention of the neighbors, and the murderer smashed this broken hole, which accelerated the speed of the residents' discovery, which would be very unfavorable to the murderer." Kudo shook his head and said.

"What if his purpose is to get the attention of the residents faster?" Watanabe spoke suddenly.

Kudo and I looked at Watanabe at the same time, both of us looking surprised.
