At the same time that Haruko Kakiya fell to the ground and cried bitterly, everyone present focused their attention on her, but Lin Xiuyi quietly looked at Yasuyuki Nantian, who was sitting on the side.

"Officer Lin, is she the murderer of the female passenger?"

The Ishibashi Officer, who was sitting in the corner, stood up from his seat angrily, if his gaze could kill, the current Kakiya Haruko was already a corpse. Ishibashi certainly has a reason to be angry, and the Cassiopeia luxury train is the flagship train that JR East has spent decades building success. For many years, JR East has been attracting visitors from all over the country and around the world with the comfortable way of traveling that is unique to the Shinkansen. But a murder would completely ruin the credibility of luxury rail travel that Cassiopeia brand represents. If the right to life of passengers cannot be protected, what else can JR East do to attract high-end customers?

"No, the murderer is actually someone else!" As soon as Lin Xiu's words came out, everyone present became even more strange, after saying so much for a long time, Mrs. Persimmon Valley is not the real murderer, so who is the murderer

"Mrs. Kakiya, I think you must have been coerced by someone to make an alibi!" Lin Xiuyi looked at Haruko Kakiya who was kneeling on the ground again, he leaned over and asked her.

"Please, don't say any more!" "Kakiya Haruko suddenly hugged Lin Xiuyi's calf and begged vigorously. She is now completely clear about her situation, Lin Xiuyi has investigated everything clearly, she can't hide this young policeman at all, the other party seems to have an ability to see through people's hearts, although Lin Xiuyi has not told everything yet, but Haruko Kakiya understands that she has no room for bargaining.

"I'm sorry, Mrs. Kakiya, but an innocent life has been involved in your matter, and if I don't tell the truth, then the real murderer of Erika Shiraishi will go unpunished. So, the next thing I have to say......"

Lin Xiuyi helped Haruko Kakiya back to her seat, then walked back to the piano, faced the 7 suspects present, and continued:

"When I first met Mrs. Kakiya, the old woman next door to Kakiya once said something that caught my attention. When you served the old lady Kakiya and drank the decoction, the old lady Kakiya once complained at that time - "Why is the medicine so bitter today?" At that time, I vaguely felt a little strange, a patient who had been taking medicine for a long time suddenly felt that the medicine had become bitter? It stands to reason that since it was a long-term drug, I am afraid that I have already become accustomed to the taste. ”

"Just now, when I finally had the opportunity to ask the old lady persimmon valley for verification alone, the reaction of the old woman of persimmon valley told me that the taste of the decoction that Mrs. persimmon valley served her in the past few days has indeed changed, so I am wondering, could it be that Cheng Fei of the decoction has changed something?"

"So I asked your daughter Tamiko about your usual steps when dispensing medicine, and Tamiko immediately took this out of her luggage and gave it to me. ”

As soon as Lin Xiu spoke, he gently took out a transparent plastic bag from the pocket of his clothes, which seemed to contain something like some kind of herb.

"This is what I got from your daughter Tamiko, and although I don't know much about Kampo medicine, I can tell that this thing is called licorice. This is a very beneficial medicine, but it is not suitable for patients suffering from certain diseases, such as Mrs. Kakiya, who suffers from heart disease. This herb can cause some kind of subtle harm to her body. In the long run, I don't think even an experienced forensic doctor will be able to find out!"

As soon as Lin Xiu said this, Haruko Kakitani's whole body trembled involuntarily, she opened her mouth, but she couldn't say anything, as if her throat was blocked by something.

"Mrs. Kakiya, I can understand the hardships of being a housewife, taking care of a sick mother-in-law for a long time, and raising children. But no matter what the reason, it can't be used as an excuse to seek other people's lives, especially in front of his own daughter, to do this kind of thing......" Lin Xiu reprimanded loudly, the whole person roared angrily, everyone present was shocked by Lin Xiuyi's momentum, and the whole room was surprisingly quiet, only Haruko Kakiya was sobbing in a low voice.

"Ms. Kakiya, there is a sentence that I don't know whether to say or not, in fact, the complaint of the old woman Kakiya that day seems to me to be more like a kind of self-talk. If my guess is correct, I'm afraid the old lady has been wishing you to change the medicine to its original flavor these days......"

As soon as Lin Xiuyi said this, Haruko Kakiya suddenly raised her head in astonishment and looked at Lin Xiuyi in surprise with a pair of crying red eyes.

"Yes, I think the old lady actually understood in her heart, she silently drank every bowl of medicine you fed her, and then said thank you from the bottom of her heart, in fact, she understood everything, just now, when I said goodbye to the old lady Kakitani, she suddenly said to me meaningfully, Haruko is the only person I can rely on......"

Haruko Kakitani's mind was like a bolt from the blue at this time, she never thought that her behavior had already been recognized by her seriously ill mother-in-law. And the mother-in-law actually didn't tell anyone anything after knowing the inside story. Haruko felt extremely remorseful in her heart at this time, how could she never pay attention to her mother-in-law's reaction, yes, she had put licorice into her mother-in-law's life-saving medicine with bad intentions, how could she dare to raise her head to look at her mother-in-law's eyes in a dignified manner?

Since Haruko married into the Kakiya family, it didn't take long for her relationship with her husband to fade, and now she, her mother-in-law, and her daughter were sent by her husband to distant Aomori Prefecture. As for her husband, she may be sleeping soundly in a hotel in Tokyo with some beautiful secretary in her arms right now! Whenever she thinks of this picture, Haruko's heart is full of hatred, and she neglects her love for her daughter and her mother-in-law's guilt for herself. Haruko had never told her mother-in-law about these things, but her mother-in-law knew better than anyone else......

"Mrs. Kakiya, the real prisoner who killed Miss Erika Shiraishi also knew about your poisoning in your mother-in-law's decoction, and used this as a threat to ask you to help him falsify the alibi, am I right!"

Lin Xiuyi walked in front of Nantian Yasuyuki and said with disdain.

"You talk nonsense...... I didn't kill people!" Yasuyuki Nanda denied in horror.
