The landlord's reasoning is easy to understand.

If the groom really intends to elope with someone, it is understandable that he asked the twin brothers to come over to take the blame to avoid a scandal in the family. But he was called by his biological mother. What kind of fate would make him give up the bride and let his brothers take his place on this crucial day of his life?

I'm afraid it's not "voluntary" but "forced".

Although the biological mother may not harm the child, it is not certain. If she planned the matter of taking the blame, there is no guarantee that she would take more drastic measures.

"Ms. Jian, I hope you can find Xiaoyan as soon as possible." The landlord said "hope", but the tone and command were no different.

Jian Jing said, "I'm not good at finding people, and the murderer hasn't been found yet. He's also your son, isn't the truth important?"

"The dead can't be resurrected, the living are more important."

"She already lost a child, what reason is there to hurt another?" Jian Jing sneered, "The chairman is very powerful, he must have a way to solve it."

Fang Dong crossed his hands, rested his chin on his folded fingers, and stared at her: "Miss Jian, few people dare to talk to me like this."

Jian Jing's reaction was just to tilt her head slightly.

Fang Dong smiled.

At his age, he may not be lenient to his subordinates, and he may be strict to his children, but he won't be too angry with beautiful girls who are different from others. Their rebelliousness and edges were "personality" in his eyes. Although Jian Jing's confrontation caught him off guard, it also won his praise.

"Do you still want to continue tracking down the murderer?" he asked.

Jian Jing thought for a while and nodded: "Yes."

"Since you insist, I have no reason to stop you." The landlord said, "Find out the murderer who killed my son."

After sorting out the two events of disappearance and death, the interference factor was ruled out, and the case suddenly became clear.

First of all, it can be confirmed that the murderer wanted to kill the groom. The poison must have been prepared in advance, and the substitution happened temporarily, and TA should not have known about it.

Therefore, the twin brothers died, but the motive for the murder should be found in the groom.

The time of poisoning was undoubtedly after the substitution, that is, after 10:40.

The two hours from 10:40 (the fake groom returned) to 13:30 (the body was found) was the time of the crime.

There are many ways of nitrite poisoning, but the deceased would not be stupid enough to be injected with drugs - there were no needle holes on his body - it should be the most common poisoning in food.

It happened that the results of the things sent for testing came out.

Both vomit and blood confirmed that it was nitrite, but no poison was found in the food sent.

Jane Jing reviewed the whole process.

The wedding time was from 11 to 12 noon. During this process, the groom did not eat any food, but drank grape juice, while the other groomsmen drank wine. But if the poison was put in the grape juice, the poison would take effect very quickly, and he should have vomited and had abdominal pain in ten minutes.

But the fake groom was very normal at the time.

Considering that there is no guarantee of the time when the poison would take effect, she tends to think that the murderer did it after the wedding. This way he would have more time to destroy the evidence.

In this way, there are very few people who can do it, only relatives or groomsmen.

We still have to find a way to poison in order to find the murderer.

She returned to the scene and looked for any fish that had slipped through the net in the waiting room.

There were many foods in the waiting room and the lounge: fruit plates, candies, cookies, cakes, drinks, nuts... But except for the fruit plates, all were sealed packages, making it difficult to take them.

Jian Jing remembered that the bride said that the groom loved to drink soda water, but the soda water in the room was bottled and all of it was sent for inspection.

She counted the empty bottles in the trash can and the number of bottles sent, and there were exactly six bottles. For the sake of beauty, the soda water was placed in a 5X3 pattern, and the number of missing bottles matched the number.

How did they do it?

She found the club attendant in charge of the groom and asked him, "Besides the fruit plate, did you send anything else today?"

Those who can work as attendants here definitely have a good memory: "Yes, we sent drinks."

Jian Jing immediately said, "Give me the same one."

"Okay."

Twenty minutes later, five cocktails were served.

The waiter pointed out: "This glass of 'Love River' is a special edition of our club, only for the newlyweds."

Jian Jing picked up the Love River. The red transparent liquor was served in a peach-shaped wine glass. It was clean and clear. When the light shone on it, it looked like a dream, and it was no longer called the Love River.

This should be for the groom.

She took a sip. It was sweet and slightly sour.

Nitrite is alkaline, salty and slightly smelly. It might be okay to put it in soda water, but wouldn't this sweet cocktail taste weird? And if you drink it, the poison will take effect on the spot. The club will definitely investigate it strictly. If the murderer takes over, it will be very obvious.

Jian Jing pondered and drank the whole glass unknowingly.

"What did you say to your uncle? Why are you drinking here alone?" Best Man Lu came over at some point, picked up a martini and took a sip. "Did you get scolded?"

Jian Jing asked, "You ordered these drinks, right?"

Best Man Lu raised his glass, "Yeah, what's the matter?"

"When was it served?"

"About 12 o'clock. I'm tired of drinking red wine. Let's change the taste." Best Man Lu shrugged.

She asked carefully: "Who brought it? Did the groom drink it immediately?"

Best Man Lu said: "Waiter, Xiaoyan was in the toilet at that time. When he came out, we were ready to eat." He thought again, "After he came out, he took a sip. How come the wine is poisoned?"

Jian Jing shook her head slowly, and suddenly asked irrelevantly: "Have you told others about our discovery of the secret ladder?"

"Yes." Best Man Lu asked curiously, "They asked me, so of course I told them."

She nodded and said slowly: "Well, I want to ask you something again, starting from A. I want to ask you something alone."

Best Man Lu said: "You can ask me first."

"I want to ask Xiaorou." She glanced at him and said calmly, "Do you know?"

Best Man Lu: "...I'll go get someone."

A came very quickly. After a day of hard work, he looked a little tired: "You want to ask Xiaorou?"

"Yes, what is her relationship with the groom, how did they know each other, and why did they break up?" Jian Jing asked carefully.

A is indeed a good friend of the groom, and he knows this very well: "Actually, Xiaorou can't be considered Yanzi's girlfriend. She is just... how should I put it, playing around. We often meet girls who take the initiative. If we can't chat, it's only a one-night stand. If we can chat, it may last for several months, and sooner or later we will break up."

Jian Jing frowned, but didn't interrupt him.

"Xiaorou has been with Yanzi for a long time, two or three years, and she thought she was the real deal. In fact, when Yanzi was dating her, he had other girlfriends, but they broke up, which made her stand out."

A's tone was flat: "Half a year ago, Yanzi met Rongrong, and then they started dating officially. After meeting her parents, she broke up with Xiaorou. I heard that she had quarreled several times, such as suicide, jumping off a building, and pregnancy. I helped Yanzi give her some money and let her go."

"According to what you said, the groom is not a loyal person. Why did he date Xiaorou for so long?"

"Xiao Rou used to be quite sensible, and she was very much like Yan Zi. But as time went by, she lost sight of her own status and position, and still wanted to marry into the Fang family." A shook his head and didn't say anything else .

But his face was full of "ungratefulness".

Jian Jing took a deep breath and decisively used the state of the concentration card.

- Reasoning should be calm, and not too many personal emotions should be mixed in.

"No other questions, by the way, call C over."

Best man C is the shortest among the best men, but he has fair skin, like a girl, and is a little uncooperative with Jian Jing's questioning: "What do you want to ask?"

"How is your relationship with the groom?" Jian Jing asked.

Best man C said: "Brother Yan is very good to me and takes good care of me."

Jian Jing said: "For example?"

"He lends me money and never forgets me when he does good things." Best man C was suspicious, "Why are you asking this?"

"I want to know what kind of person the groom is." She said calmly, "Go on."

Best man C, however, became alert: "Nothing else."

"Then let's talk about Xiaorou." She said, "I think she is a major suspect."

Best man C sat up straight, his face full of surprise: "Xiaorou?"

Jian Jing said: "Do you know how they met? If the groom is really as good as you say, why did he break up with her and immediately marry a girl he had only known for half a year?"

Best man C hesitated for a moment and said: "Brother Yan never thought about marrying Xiaorou, he was just playing around."

"You didn't answer me, how did they know each other."

He was silent for a moment, and whispered: "Xiao Rou went to a party with her friends, and then she met Brother Yan. But she is just an ordinary girl, murdering someone... I don't think it's possible."

"Are you familiar with Xiao Rou?" Jian Jing seemed to have just remembered something and asked casually, "By the way, didn't you try to contact Xiao Rou before? Is she still in this city?"

Best man C was a little embarrassed: "The friend I called couldn't find her, and her phone number has changed."

"Changed her phone number? It seems that she was prepared and prepared to escape." Jian Jing lied without changing his expression, "Is there anyone else in her family?"

Best man C said: "I don't know."

"Really?"

"You suspect me?" Best man C stood up suddenly, his face flushed. "I tell you, you can eat anything you want, but you can't say anything you want."

Jian Jing said, "Of course I have my reasons for saying this - you sympathize with Xiao Rou, right? The other people all look down on a woman like her who is trying to curry favor with the rich and powerful. Why do you want to defend her?"

"She couldn't even get into the wedding today, how could she kill someone?" Best man C said coldly, "I just have reasonable suspicions."

"You're right to suspect." Jian Jing said, "You're the only one who can kill someone today."

Best man C had a lot of rebuttals in his mind, but he didn't expect her to skip the middle step and show his true colors directly: "Are you saying I'm the murderer?"

"Yes."

Her tone was very calm, as if she was reading aloud the news in the newspaper: "The situation is special, the time for poisoning can be shortened to between 12:00 and 1:30, and only a few of you can do it."

Best man C said coldly: "Then why me?"

"Because at 12:15, you were the only one who saw the groom." Jian Jing said, "Nitrite poisoning reacts quickly, and everyone else has an alibi. You were the only one who returned to the lounge during that time."

Best man C said: "Is there any evidence? You said I poisoned him, how did I do it?"

"Indeed, the method of poisoning has troubled me for a long time." He saw the beautiful girl in front of him relax her body, leaning back in the velvet armchair, fingers crossed, full of the calmness of a detective, "No poison was detected in the food and drinks at the scene, and under the circumstances at the time, it was impossible to force the poison by force."

Best man C said: "So you are talking nonsense and looking for me to be a scapegoat?"

Jian Jing ignored him and said slowly: "But I later figured it out. In addition to secretly drugging and forcefully drugging, there is another way, that is to take the initiative to let the deceased take the medicine."

"Is he crazy? Who would take poison by themselves?" Best man C retorted loudly.

"Not poison, but what about medicine? "Jane Jing said, "He is allergic to alcohol. What if someone told him that the drink he had drunk before contained alcohol and asked him to take anti-allergy medicine?"

Best man C was like a chicken with its neck strangled. He was speechless and looked at her in shock.
