Yun Yeyao's idea is actually very simple, there is a total of one main door in the hotel, six guest room doors, and one kitchen door and one bathroom door, and the total number of door keys is exactly nine, but there is a back door in the warehouse behind the kitchen, where is the key to the back door? Could it be that the back door of the kitchen is not locked at all?

Although there is really no way to lead to a place through the back door according to the direction, most of the people on the island are very water-based, and the back door is open to the big lake, isn't it also a special road for them? And there is direct access to all parts of the island. In other words, you can also enter the interior of the hotel from various places on Bifang Island without realizing it.

Yun Yeyao began to secretly think about something, this was the first time he learned to analyze the case in detail, and find flaws in it, and the temperament of the whole person was gradually changing, and he began to get close to someone he remembered.

Turning your gaze back to the three aunts. Among the three people, only Aunt Tao had more contact with them, and it felt more relaxed, and the other two aunts were very restrained, for fear that they would say the wrong thing, and there were not too many seats in the room, so the aunts could only sit on the wooden box on one side. Aunt Tao sat in the first one, and the other two aunts sat behind her in turn, as if they had not yet shaken off the fright.

After Xie Yunmeng waited for them to sit down, he directly asked Aunt Tao, "The room we are in now should be Kang Chen's room, right?" Yun Yeyao had also asked this question before, and Xie Yunmeng deliberately asked it again here, wanting to test Aunt Tao.

"Yes, I already talked to Mr. Yun at noon." It seems that this aunt is relatively honest and has a good memory.

"I said it didn't look like a man's room, do you remember?" Yun Ye asked.

"I remember you asked me, but Kang Chen was originally a young man who loved cleanliness, and his room was tidy and tidy, and it was nothing." Aunt Tao didn't quite understand what Yun Yeyao meant, so she could only explain it according to her own words at that time.

Yun Yeyao shook his head and said, "It's not just clean, but there are other aspects, Aunt Tao, let me ask you, when did Kang Chen come to this island?" ”

"About half a year ago."

"It can't be half a year, because I've locked him up for more than two months." Xie Yunmeng interjected. Indeed, he solved Kang Chen's brawl more than half a year ago, plus he was imprisoned for more than two months, Kang Chen's time here was three or four months at most.

Aunt Tao was refuted by him, she didn't pick up the conversation for a while, paused slightly, turned her brain, and quickly replied: "Three or four months, probably, I don't remember the specific date, it's probably that long." ”

"Aunt Tao, please think clearly before answering our questions, you must tell us the truth, okay." Xie Yunmeng said solemnly.

Aunt Tao was a little embarrassed by what he said. However, he immediately replied: "I know, Mr. Detective, don't worry." ”

Xie Yunmeng continued to ask, "Before Kang Chen came to this island, who lived in this room?" After asking, he immediately added: "The next questions, the aunts can all answer, we are not asking Aunt Tao alone, but asking the three of you." ”

After the other two aunts glanced at each other, they nodded at Xie Yunmeng, they looked a little hesitant, maybe there is really some secret on this island, and the aunts don't know if they will leak their mouths, so they will be like this.

Yun Yeyao and Xie Yunmeng have been paying attention to the changes in the expressions of the three of them, the young criminal policeman does not dare to relax for a moment, it is the first time for him to deal with this kind of vicious homicide case, he feels the pressure hovering above his head like a mountain, and the nerves in his body are tensed, for fear of missing a little clue.

The interruption of external contact is now the biggest trouble, and Yun Yeyao doesn't seem to have much fear, since he sat down, he has become more and more calm, and he is gradually like two people as usual.

Xie Yunmeng suddenly had the impression that he seemed to have felt the same calm and wise in someone. He didn't know this person, he had only heard the teacher mention it, and he didn't even know his name.

Putting aside his inconsequential thoughts, Xie Yunmeng continued to listen to the conversation between Yun Yeyao and his aunts, maintaining a high degree of vigilance in order to ask the questions he wanted to know.

At this time, the criminal police found a problem, Aunt Tao has been putting her hands in her pockets since she entered the room, which is not like the habit of a middle-aged aunt, and it can be seen from the shape of her pockets that she has been clenching her fists, as if there is something in her palm, and her sitting posture is also a little strange.

The two of them waited for the aunt to answer the question just now, that is, before Kang Chen arrived, who lived in this room?

But the question seemed to make the aunts seem a little embarrassed, and they hesitated for a while, and finally one of them spoke, it was an aunt of medium stature, with broad shoulders, but who did not look very fat. The fingers on the knees are short and thick, the skin on them is white, each nail is short, and there is some dirt in the crevices, which is caused by long-term cleaning of fish and shrimp and soaking in water.

The aunt, who was slightly shorter than Aunt Tao, said, "This room has always been empty, and if anyone has to live in it, it's the patient in the fourth room of the hotel." Before Kang Chen came, Lao Nuo would occasionally move her over for a while, only for about three or five days, most of the time she still lived in a hotel, anyway, Lao Nuo took care of her alone, and we never intervened. ”

"Do you know who the patient is?" Xie Yunmeng asked.

The aunt who spoke looked back at Aunt Tao and asked her, "Xiao Tao, you should know, right?" You have a close relationship with Lao Nuo, the two of us came later, and Lao Nuo never mentioned to us who the patient was. ”

"I don't know, this matter seems to be hidden very deeply, and there should be few people here who know about it. By the way, Convoy will probably know. But this old man is stubborn, and no matter who asks him about the past, he doesn't want to say anything, and I feel as if he has some taboo about the past. ”

"Then you can tell me that you know that these rooms are usually cleaned up all the time?" Xie Yunmeng changed the topic slightly and asked.

"In the past, Lao Nuo cleaned it up alone, and he never let us get close to the patients."

"Then you don't have any guesses about the patient's identity?" Yun Ye asked.

Aunt Tao replied, "There is a guess, but we don't know if it's correct." Everyone thinks that the patient should be Lao Nuo's wife. Probably because she had a bad problem, that's why she didn't want everyone to know. ”

"And how long has she been sick?"

"I don't know, it must have been many years, since we arrived on the island, Lao Nuo has been taking care of the sick. It's probably going to be more than 10 years. It was Aunt Tao who answered, and the other two aunts were reluctant to speak more, so they kept their heads down.
