Chapter 475 475: A Smell Of Lemon

Through all these points, she thought it must be an accident and that the real person the murderer intended to kill was not Shirley.

She also wondered if the target person was Henry, then why William was poisoned too.

"I am sure that the target person is William from the beginning," Irish added to the main point.

"Shirley was poisoned because she ate the dessert that did not belong to her after the meal. And it is definitely an accident for the murderer since he couldn't expect who would not eat the dessert.

But it was complicated for William's case.

According to the steward, the Lake families were used to drinking afternoon tea around half past three. William had been accustomed to the habit for so many years, let alone the hot tea would make him feel warm since he was afraid of cold days.

Everyone was at home today except for Roy, Ruby, and Kelly, who went out to buy tea. And the servants would not serve the tea mistakenly since all of them were in their own rooms, so the murderer's goal was obvious.

Joseph nodded since he also agreed with Irish's analysis. The policemen had made a specific inquiry to those servants and decided that those five temporarily hired people didn't get the chance to get close to their bedroom since they were hired to do some outdoor work. Kelly was also taken to the police station when she went back, but Joseph didn't think she was the murderer since she had no motive to do that.

Therefore, perhaps the murderer would be among those servants.

"I think the murderer didn't put the poison in the tea. It was used to cover up the story." Irish made an assumption and then added, "But you have to help me to analyze since I always feel there is something I can't figure out."

Joseph also mentioned some suspicious points to her on the phone. Though she had some ideas, she couldn't find evidence to support her idea.

The poisoned process for Shirley and William was the same, but they had different symptoms after being poisoned. At least Shirley hadn't been in a coma for so long. What's more, it could tell that William just took a small sip of the tea to find out the temperature of the tea based on the amount of the tea left over.

"William would be used to drinking the tea with proper temperature, so he would try it first, and he would not drink if it were cold or hot." Joseph squinted and added, "But the size of the cup, the number of snacks, and the water level of the tea in the cup are all of the same standards, so he did not drink the tea at all. Even if he was poisoned by the tea left over in his lips, it was unreasonable that he would have been in a coma for such a long time."

It was the detail he found this afternoon, but he was confused if the tea did not poison William, then what would it be?

However, Irish was enlightened by his words, and she stood up abruptly, grabbed Joseph's arm, and asked, "The heater."

It was what she couldn't see through because she didn't know that William didn't drink too much tea but only knew he was in a coma. In this way, her assumption was right, and the murderer had envenomed elsewhere, and the tea was just a camouflage.

But Joseph was confused by her words.

Irish reached out and fanned before him, "What do you smell?"

Joseph frowned and said, "A smell of lemon." He had smelt this upon entering the house, but he could hardly smell it as time passed by.

Irish nodded and stared at him while her eyes were flickering.

Joseph was smart and soon got the key point, "Someone added the air-purifying items to the heater, so there is the smell of lemon." He thought the servant sprayed the air fresheners into the room.

But it was not fresh news since many hotels would add some air purifiers into the air conditioners and heaters to purify the air.

He didn't notice it because he hardly came here and he also didn't feel cold, so he didn't turn on the heater. And in the killing freeze days, the geothermal system would start over, so there was no need to use the heater.

"Are you suspecting that someone tried to kill William through the airflow from the heater?" Now that the aroma of lemon can be added to the heater, it also can release the poison gas.

Moreover, William was the only one who used the heater these days and was alone in the room.

Irish took a deep breath and nodded again, "Perhaps we will find out the clues if we go to check the heater now."

But Joseph shook his head and said, "But the heater broke down just thirty minutes after William was sent to hospital, so it was moved away. We can't find out the evidence from that now."

"What a coincidence!" Irish was more assured, and it was no wonder a servant would send back the remote control to William's room at dinner time. It must have been left in the living room when the heater was moved away and was searched by the police.

"According to our analysis, the murderer is very familiar with the electrical circuit, so he knew when to put the poison at a proper time. Therefore, even if someone intends to investigate it later, it is impossible to find out any evidence anymore." Joseph said while thinking.

"There are five people responsible for the circuit maintenance in the Lake family. Do you think the murderer will be one of them?"

Joseph thought for a while and replied, "A culprit acts like a cop? I don't think he would be so audacious."

Irish lay down again and bit her lips tightly.

Joseph moved slightly and leaned on the bed, reaching out to caress her hair and suggested, "You can try to analyze the mentality of the murderer, and perhaps you could find out the clues soon."

After a while, Irish stared at the ceiling and said slowly, "I am afraid he is in a dangerous mental state."

Joseph held her and frowned, "Why do you say this?"
