First of all, the first suspicious person to enter the third floor was Uncle Zheng.
Although according to time, the uncle was by no means the last one to see Li Quan, Li Quan died due to drugs, and time alone cannot be used to determine who is the murderer.
"If I don't tell him something, I haven't done anything." Uncle Zheng said.
"What can you talk to him about? As far as I know, you just asked me to borrow money this morning, and we didn't even get it. How could he lend it to you?" Zheng Jiayu said.
"I just want to try it anyway." Uncle Zheng said.
Locke thought for a while, Uncle Zheng also had the opportunity to get access to heart disease drugs, but he just borrowed money and had no motive for committing the crime. He was ready to ask the next suspect.
At this time, the police from the island district also arrived. The police captain first sent people to collect evidence, and Locke handed the water cup to the police officers and asked them to try to extract fingerprints from the cup wall.
"Hello, Mr. Luo, and this lady, I didn't expect you to be here too." The leading police captain also participated in the last mission on Cheung Chau Island. He immediately recognized Locke and Chen Yuanyuan and stepped forward to ask.
"Hello." Chen Yuanyuan greeted with a smile.
"Well, I'm interrogating, you should sit down and listen." Locke nodded.
Originally, some members of the Zheng family felt unhappy when they saw that Locke was just a young boy who had been leading the investigation and questioning them. However, seeing the police's respectful attitude, they couldn't help but look at Locke.
After the police captain sat down, he quietly took notes and waited for Locke's interrogation.
Seeing the serious attitude, Chen Yuanyuan immediately straightened her back and listened carefully.
Locke turned his eyes and looked at the servant Feifei who looked guilty.
"You brought that glass of water, right?" Locke said.
Feifei, who felt guilty, immediately lowered her head as soon as she caught everyone's attention.
"I just went to deliver afternoon tea to Mr. Li." Feifei explained hurriedly.
"Chef Wang, has anyone had afternoon tea this afternoon?" Zheng Jiayu saw that she was in a bad state and turned to the chef.
"Mr. Zheng, my wife and Master Zheng Lixing had afternoon tea this afternoon, but I didn't see this servant coming to the kitchen to get anything." Chef Wang said.
"Can you explain why you were on the third floor from four-thirty to five o'clock? And why you were so panicked when you left." Locke asked.
"I" Feifei turned pale and hesitated, not knowing how to explain.
"She is not a murderer, so how could she be willing to kill her lover." Zheng Jiafu sneered.
Seeing everyone staring at her, Zheng Jiafu continued to explain.
Zheng Jiafu was in charge of liaising with the authorities outside. He learned from others that Li Quan actually had a list of people who supplied fishery products to the Zheng family, and privately asked the Li family to ask those fishermen for the goods.
After learning about it, Zheng Jiafu hurried back to the island and went directly to the third floor to confront Li Quan. Unexpectedly, he encountered Li Quan and Feifei doing something inappropriate.
Li Quan, who has always been an honest person, not only betrayed the Zheng family, but also betrayed his sister Zheng Jiamei. He was so angry that he had a big fight with Li Quan.
Zheng Jiafu frankly admitted that he had a fight with Li Quan. Feifei was so frightened that he left the room, but he did not beat Li Quan to death. Li Quan's back of the head was not injured before leaving.
"Butler, what brought you to the third floor?" Locke then asked the third old housekeeper who went to the third floor.
"My master asked me to take a look. He heard the sound of fighting upstairs and asked me to go down and have a look." The old housekeeper said.
Locke asked others for some details, and Chen Yuanyuan kept listening and roughly guessed what was going on.
After one round of interrogation, although we have a general picture of the case, we still can't get a result. In the future, there is no technology to investigate the case, and there is no way to know who is the person who gave the heart disease medicine.
"Report, we found five people's fingerprints in the water glass, one of them belongs to the deceased, and the other four need to be compared." A police officer came forward and said.
"Two of them belong to me and the doctor, and the remaining two are either the murderer or the accomplice." Locke said.
Upon seeing this, the police captain began to take fingerprint samples from everyone. When it was the old housekeeper's turn, Mr. Zheng took the old housekeeper's hand.
"Okay, no need to check, just withdraw." Mr. Zheng said sternly.
"Sir, I" said the old housekeeper.
"I am old, but not blind. If I were not in a wheelchair, I would not let him go." Mr. Zheng said angrily.
It turns out that the uncle has been selling the Zheng family's fishermen's supply list to Li Quan at a low price for profit.
The night before yesterday, the master was having a big quarrel with his uncle over this matter, and Master Zheng's heart disease pills also fell to the ground, which was collected by the old housekeeper.
When Chen Yuanyuan and his entourage arrived the next day, the uncle at the dinner had a bad look all night.
The old housekeeper who had been following Mr. Zheng had always been on good terms with the family doctor and had long heard about Li Quan's use of sildenafil.
But seeing the close interaction between him and Zheng Jiamei, I just thought that the two of them had tasted the forbidden fruit and didn't think too much about it.
But before today's incident, the uncle saw that he couldn't get the money from the master and the incident was revealed, so he threatened Li Quan before he was exposed and wanted to take the opportunity to make a fortune. As a result, the two of them got into an unpleasant quarrel.
Li Quan, who was in a very bad mood, saw that Zheng Jiamei was not there, so he secretly found his underground lover Feifei to relieve his mood.
Since Feifei fell in love with Li Quan, although she is also a secret lover, she has been taken care of in terms of food and life, so without thinking much, she poured a glass of water and pretended to give Li Quan afternoon tea.
With the help of drugs, the two indulged in the excitement of the affair, but they were unexpectedly bumped into by Zheng Jiafu who returned and wanted to question Li Quan.
Zheng Jiafu was originally very angry because of Li Quan's secret business digging, but he didn't expect to be caught and raped in bed by Li Quan. He was so angry that he started a fight with him.
Later, Mr. Zheng asked the old housekeeper to come to the scene to persuade him to make friends. He heard about Li Quan and Feifei in Zheng Jiafu's insulting words. He also found the bracelet Feifei left behind when he left in a hurry in the room, and then discovered that Li Quan had betrayed Zheng Jiamei.
After Zheng Jiafu slammed the door and left, Li Quan saw that the old housekeeper had also arrived. He thought he could no longer hide it, so he simply broke the jar, packed the valuables in the safe and some important items he had collected, and packed his luggage to leave the island immediately.
Upon seeing this, the old housekeeper immediately tried to persuade Li Quan and told him that he would not expose his cheating. Li Quan also drank more than half a glass of water while talking to the housekeeper.
When the old housekeeper saw that he was beginning to feel a little unwell, he made an excuse to find a doctor for him, but in fact, he went to find Mr. Zheng to report Li Quan's situation.
It turned out that the old housekeeper had just crushed the broken pills into powder and put them into the water cup while packing his luggage, so there was residual powder in the water cup.
Although the old butler knew that heart disease medicine would lower blood pressure, he just wanted to use the medicine to make him feel sick and delay his stay on the island.
Just as the old housekeeper and Mr. Zheng finished discussing Li Quan's situation, they decided to wait until the guest left tomorrow before having a showdown with him.
The old housekeeper went to the kitchen to bring dinner to Li Quan, and told Zheng Jiamei that Li Quan was unwell and needed to rest in the room and asked her not to disturb him.
Unexpectedly, when he returned to the room again, Li Quan was lying on the ground without breathing.
The old housekeeper was not a person proficient in pharmacology, so he did not expect that taking the two medicines at the same time would produce such results.
The old housekeeper hurriedly went to find Mr. Zheng, but before he could move the body, Zheng Jiamei found that her fiancé was dead.
