First of all, the first person to enter the third floor in the surveillance, the suspicious person is Uncle Zheng.

Although according to time, Uncle was by no means the last to see Li Quan, but Li Quan was killed by drugs, and time alone could not be used to determine who was the murderer.

"I'm not just going to talk to him, I'm not doing anything." Uncle Zheng said.

"What can you talk to him about? As far as I know, you just asked me in the morning to borrow money, and we didn't even borrow it, so how could he lend it to you. Zheng Jiayu said.

"I'm just going to try it anyway." Uncle Zheng said.

Locke thought about it, Uncle Zheng was also a person who had access to heart drugs, but he just couldn't borrow money, and the motive for the crime was not big, so he was ready to ask the next suspect.

At this time, the police in the island area also arrived, and the captain of the police first sent someone to collect evidence, and Locke handed the water cup to the police officers and asked them to try to extract the fingerprints on the wall of the cup first.

"Hello Mr. Luo and this young lady, I didn't expect you to be here." The police captain who took the lead also participated in the last mission on Cheung Chau Island, and immediately recognized Locke and Chen Yuanyuan, so he stepped forward and asked.

"Hello." Chen Yuanyuan smiled and said hello.

"Well, I'm interrogating, you can sit down and listen." Locke bowed.

Originally, some members of the Zheng family were unhappy when they saw that Locke was just a hairy boy who had been leading the investigation and questioning them, but seeing the police's respectful attitude, they couldn't help but look at Locke twice.

After the police squad leader sat down, he quietly took notes on the side, waiting for Locke's interrogation.

Chen Yuanyuan saw that he was quite serious, and immediately straightened his waist and listened seriously.

Locke's eyes turned, and he looked at the servant Fei Fei with a weak expression.

"You brought that glass of water." Locke Road.

As soon as the weak-hearted Fei Fei came into contact with everyone's eyes, she immediately lowered her head.

"I'm just going to deliver afternoon tea to Mr. Li." Fei Fei hurriedly explained.

"Chef Wang, did anyone have afternoon tea in the afternoon?" Zheng Jiayu saw that she was not in the right state, and turned to the chef to ask.

"Zheng Gongzi, Mrs. Zheng and Young Master Zheng Lixing had afternoon tea in the afternoon, but I didn't see this servant come to the kitchen to get something." Chef Wang said.

"Can you explain why it's on the third floor from half-past four to five? And why was there such a panic when leaving. Locke asked.

"I" Fei Fei brushed her face white, and she didn't know how to explain it.

"She is not a murderer, how can she be willing to kill her lover." Zheng Jiafu sneered.

Zheng Jiafu saw that everyone was staring at her, so he continued to explain.

Zheng Jiafu was in charge of liaising with the government outside, and learned from others that Li Quan actually had a list of fishing goods for the Zheng family, and privately asked the Li family's people to ask those fishermen for the goods.

When Zheng Jiafu learned about it, he hurriedly rushed back to the island, and when he went directly to the third floor to confront Li Quan, he didn't expect to encounter Li Quan and Fei Fei doing misdeeds.

Li Quan, who has always been an honest person, not only betrayed the Zheng family, but also betrayed his sister Zheng Jiamei, and he fought with Li Quan in anger.

Zheng Jiafu admitted that he had fought with Li Quan, and Fei Fei was so frightened that he left the room, but he didn't beat Li Quan to death, and Li Quan was still not injured in the back of his head before leaving.

"Butler, what is the matter with you going to the third floor?" Locke then asked the third old butler who had gone to the third floor.

"It was the lord who asked me to go and see it, and the lord heard the sound of fighting upstairs, so let me go down and have a look." The old butler said.

Locke asked the others for some details, and Chen Yuanyuan listened and probably guessed what was going on.

After a round of interrogation, although there is a rough spectrum of the case, there is still no result, there is no technology to investigate the case in the future, and there is no way to know who is the person who put heart medicine in the end.

"According to the report, we found the fingerprints of five people in the water glass, one of which was deceased, and the other four need to be compared." A police officer stepped forward.

"Two of them belong to me and the doctor, and the remaining two are either murderers or accomplices." Locke Road.

Seeing this, the police squad leader began to take fingerprint samples from everyone, and when it was the turn of the old housekeeper, Master Zheng took the old housekeeper's hand.

"Okay, don't check it, let's withdraw." Old Man Zheng said sharply.

"Master, I," said the old butler.

"I'm old, but I'm not blind, and if I wasn't in a wheelchair, I wouldn't let him go." Master Zheng said angrily.

It turned out that for the sake of profit, the uncle had been selling the Zheng family's list of supply fishermen to Li Quan at the reserve price.

And the night before yesterday, the old man was having a big fight with the uncle because of this matter, and the heart pills of the old man Zheng also fell to the ground, which was collected by the old housekeeper.

After Chen Yuanyuan and his entourage arrived the next day, the uncle at the dinner party also had a stinky face.

The old housekeeper, who has always been by Mr. Zheng's side, has always been friendly with the family doctor, and he has long heard about Li Quan's use of sildenafil.

But seeing the intimate interaction between him and Zheng Jiamei, he just thought that the two had secretly tasted the forbidden fruit, and didn't think too much about it.

And before today's case, the uncle saw that he couldn't ask for money at the master's place, and the incident happened in the east window, so he threatened him before Li Quan was exposed, trying to take the opportunity to make a profit, but the two were unhappy.

Li Quan, who was in a very bad mood, saw that Zheng Jiamei was not there, so he quietly found his underground lover Fei Fei to relieve his emotions.

Since Fei Fei fell in love with Li Quan, although she was also a lover who couldn't see the light, she was also taken care of in terms of food and life, so she didn't think much about it, so she poured a glass of water and pretended to send afternoon tea to Li Quan.

With the blessing of the drug, the two were immersed in the excitement of cheating, but they didn't expect Zheng Jiafu, who came back and wanted to question Li Quan, to bump into each other.

Zheng Jiafu was originally angry because of Li Quan's private digging business, but he didn't expect to be caught and raped by him in bed, and he was angry and beat him.

Later, Master Zheng asked the old housekeeper to come to the scene to persuade him, and heard about Li Quan and Fei Fei in Zheng Jiafu's abusive words, and found the bracelet left by Fei Fei when he left in a hurry in the room, only to find that Li Quan had betrayed Zheng Jiamei.

After Zheng Jiafu slammed the door and left, Li Quan saw that the old housekeeper was also coming, and thought that he couldn't hide it anymore, so he simply broke the jar and broke it, packed the valuables in the safe and some important items he had collected, packed his luggage, and prepared to leave the island immediately.

Seeing this, the old housekeeper immediately persuaded him and told Li Quan that he would not expose his cheating, and Li Quan also drank most of the glass of water during the conversation with the housekeeper.

The old housekeeper saw that he was starting to feel a little unwell, so he used the excuse of finding a doctor for him, but in fact went to Mr. Zheng to report Li Quan's matter.

It turned out that the old butler had lined him with the broken pills when he was packing his luggage, and kneaded the broken pills into powder and put them in the water cup, so there would be residual medicine in the water cup.

Although the old butler knew that heart medicine would lower blood pressure, he just wanted to use the medicine to make him unwell and delay his stay on the island.

And just as the old housekeeper and Master Zheng had discussed Li Quan's matter, they decided to wait for the guests to leave 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 wanted to rest in the room, so that she should not disturb him.

Unexpectedly, when he returned to the room again, Li Quan lay on the ground and no longer breathed.

The old housekeeper is not a person who is proficient in pharmacology, so he didn't expect that taking the two drugs together would make such a result.

hurriedly got off the old housekeeper and immediately went to find Master Zheng, but before he could transfer the body, Zheng Jiamei found that her fiancé had died.
