The tea leaves are the best Longjing tea, with a few pieces and uniform leaves.

However, there was an extra leaf of Tieguanyin in the teacup, which was a bit out of place.

Lord Wei likes to eat black tea, and occasionally mixes in a leaf of Tieguanyin, and no one will find it strange.

But Mrs. Lin said that the deceased had insomnia recently, so she was unwilling to let him eat strong tea, so she deliberately replaced it. How could such a caring person mix two different styles of tea together and affect the taste?

Wei Gongzi did not leave and waited at the door. Leng Qinghuan asked him, "Is there Tieguanyin tea in Lord Wei's study?" ”

Wei Gongzi shook his head: "My father likes tea, and he is also particular about drinking tea, he said that the smell of ink will affect the smell of tea, so he never stores tea in the study, and sends it in after it is cooked by a special servant." ”

So where did this piece of Tieguanyin come from? Will there be any mystery in this?

If it is true that someone else poisoned him, why do he need to do this and leave evidence of the crime to arouse suspicion?

Leng Qinghuan frowned and pondered for a moment, his eyes slowly swept over the study, raised his hand and pointed, and asked Wei Gongzi: "Why is there a hole left above the window of this study?"

Wei Gongzi glanced up and explained: "My father was afraid of smelling charcoal, so when he was making charcoal stoves in the winter before, he erected a chimney from the window position. However, in recent years, I have changed the silver frost charcoal, and there is no smell. My father ordered it to be demolished, and the hole was not blocked, and the cool breeze was blowing when it was cold. ”

Shen Linfeng heard Leng Qinghuan ask like this, there must be a reason, so he moved a chair and stood on it to look, the hole was very small, it was only the size of a bracelet, and he really couldn't find it if he wasn't careful.

His gaze flickered in, and when he came out, he had a black feather between his fingertips.

"It seems to be a starling."

Shen Linfeng was suddenly a little excited, if this was just an ordinary sparrow feather, after all, the sparrow originally liked to find these places to make a nest, but this is the starling's feather, and things are not simple.

"Lord Wei has a penchant for raising birds?" He asked, twisting his face.

The prince of Wei Mansion shook his head: "He is busy with official business, how can he have such leisure?" ”

"Call the subordinates who guard this place on weekdays and ask them, Pingsuli, is there a starling in and out of Lord Wei's study?"

Wei Gongzi only felt inexplicable and didn't understand what Shen Linfeng's intentions were, but he still went out to summon the servants according to what he said.

"My cousin-in-law is really good eyesight, I searched this study twice, but I didn't see it."

There can be a little breakthrough in the case, and Shen Linfeng's tone could not hide the excitement.

"When he came in, he saw smoke coming out of here. Otherwise, I wouldn't have noticed. ”

"In addition to being good at learning tongues, after training, he can also pass on letters, could it be that Lord Wei has been transmitting messages through flying birds, who has kept in touch with him?"

Out of professional acumen, he immediately smelled a different smell from it: "In particular, the correspondence between them is not visible, so Master Wei often burns letters in the study. ”

Leng Qinghuan didn't think of this at all, because she paid attention to another point. As long as it is confirmed, the mystery of poisoning can be solved immediately.

The subordinate quickly came in, bowed his head and stood in front of Shen Linfeng, a little apprehensive, very worried that he would be implicated in this case.

"This official asks you, in your lord's study, can there be a black starling in and out on weekdays?"

One of the subordinates nodded: "Yes, the villain has seen it before." It was not afraid of people, so it stood on the eaves opposite and stared at me, I wanted to catch and play, but my master stopped drinking. ”

"Then last night, did you see this starling?" Leng Qinghuan asked.

The subordinate shook his head: "As soon as the night falls, there are lanterns in the courtyard, and bats are flying around in the sky here, so naturally you can't notice anything else." ”

That's enough.

Leng Qinghuan smiled slightly: "I already know, how did the other party poison?" ”

"How to poison it?"

Shen Linfeng and the prince of Wei Mansion spoke in unison. Especially the prince of Wei Mansion, his mother is still suspected of murdering her husband, which makes him more anxious than Shen Linfeng.

"Shen Shizi can't guess?"

"You mean, it's this starling?" Shen Linfeng was a little incredulous.

Leng Qinghuan nodded, and handed the tea cup to Shen Linfeng: "Look, what's wrong with this tea?" ”

Shen Linfeng was already puzzled when he heard her ask about this tea, and when he looked carefully at the tea leaves in the tea cup, he suddenly realized: "This Tieguanyin tea is used to wrap poison!" Because Lord Wei likes to drink Tieguanyin on weekdays, if he is poisoned like this, he can be unaware. It's just that he didn't know that Mrs. Lin temporarily changed the tea to Longjing. ”

Leng Qinghuan nodded: "The outside of the pill is wrapped in tea leaves, and the starling's mouth is slender, and there is no saliva infiltration in the mouth, and the tea leaves will not stretch." It was supposed to be in and out of Lord Wei's study often, so Lord Wei was defenseless against it and let it stay on top of his bookcase.

Maybe at that time, Lord Wei was focusing on other things and had no time to look around. It secretly added the pill to the hot tea in front of Lord Wei, the tea leaves stretched, and the poison in it dissolved when it was hot, Lord Wei was unaware, and after eating it, he died of poison. And the murderer just escaped without a trace. ”

Shen Linfeng hammered his palms excitedly: "How did I not think of it before?" ”

Because, I've seen too much reasoning. There are so many ancient wisdoms, only you can't guess it, and there are no authors who can't think of it.

"The soldier who was killed before, Lord Feng, should also have the same cause of death, and the poison was also in the tea, colorless and tasteless."

"I remember you once said that one of the deceased's favorite pendants disappeared for no reason, and it should have been stolen by this thief. Some birds just like these shiny things. Moreover, it was still hot, and the doors and windows were wide open, so the birds could come and go freely. ”

Her reasoning was immediately recognized by Shen Linfeng, and the prince of Wei Mansion was even more happy, because he could finally clear his mother's suspicion of murder.

Shen Linfeng turned his face and asked Wei Gongzi: "Who is the person who has been communicating with Ling Zun, do you know?" ”

Wei Gongzi shook his head: "My father's study is unwilling to let us in and out, and my mother is cleaning him personally on weekdays. In the past two years, things about the court have rarely been mentioned to us, and every time I talk about it, I am always a little irritable and inexplicably angry. So, we rarely ask. ”

"And does your mother know?"

"Mother she can't read a few words, and she never asks about her father's business. She was in bed because of her father's death, and if Shen Shizi wanted to inquire about some specific situations, please move. ”

This matter is not trivial, it is related to the key to solving the case, so Shen Linfeng immediately went to Mrs. Wei's Lin room with Leng Qinghuan.
