"No... No, you're not wrong, sir, are you? Cui Yuanhao was a little unfavorable when he spoke.

"You ask her yourself", Nie Xiaohu smiled.

Cui Yuanhao looked at Meng Shi beside him suspiciously, looking a little overwhelmed, while Meng Shi sat there without saying a word, his slightly closed eyes never opened, still twisting the Buddha beads slowly and methodically, and chanting words silently in his mouth.

"Since Mrs. Meng refuses to say, then I'll do it for you!" , Nie Xiaohu smiled slightly.

"At first, I was just suspicious of Mrs. Meng, think about it, in this case, how many people know that the pearl necklace is hidden in the secret room in the backyard?"

Without waiting for everyone to speak, Nie Xiaohu continued: "Four, there are only four people in total, that is, Cui Yuanwai, Mrs. Meng, Shopkeeper Feng and Song Zhe, and now that Song Zhe is dead, then the murderer can only be one of the three people Cui Yuanwai, Mrs. Meng, and Shopkeeper Feng."

Although I was suspicious of all three of them, I never understood how the murderer managed to escape in an airtight secret room, and when I thought about it to no avail, I calmed down and asked myself if I was too entangled in the murderer's modus operandi.

Putting that aside, I tried to think about the whole thing backwards, and it became clear that I had also locked the killer on two people, but I couldn't be sure who it was. ”

"Thinking the other way around?" , Cao Xiaohui frowned and asked, "How is it the other way around, which two people are they?" ”

"It's Cui Yuanwai and Mrs. Meng!"

Nie Xiaohu's index and middle fingers of his right hand quickly clicked on his thigh a few times, and continued: "Normally, the victim is the victim, but what if it is the other way around? For example, what if the victim is also the perpetrator? ”

"The victim is also the perpetrator?" , Cao Xiaohui thought about it, suddenly widened her eyes and said, "Oh~~~, you mean ......"

"That's right!" , Nie Xiaohu snapped his fingers with a smile.

"In this case, although Song Zhe is the victim, he is also one of the criminals! Judging from the situation of the secret room, a person cannot go out after locking the door in the secret room anyway.

But if Song Zhe is also a criminal, and he has an accomplice who is answering outside, then things will be much simpler. ”

"That's right! In this way, all mysteries are not mysteries! Cao Xiaohui's eyes lit up with excitement.

Nie Xiaohu smiled, and then said: "The murderer first agreed with Song Zhe in advance, just last night around midnight, the murderer arrived at the door of the secret room as promised, Song Zhe opened the iron box, took out the pearl necklace, and handed it to the murderer through the vent on the door, but the murderer wanted to swallow the necklace alone, so he stabbed him in the chest with a dagger when Song Zhe handed the necklace at the door.

Song Zhe was stabbed and retreated, leaving a few drops of blood on the floor at the door, and then he fell to the ground and died, as for the loss of the necklace, it didn't matter what excuse the two had agreed on in advance.

As for whether the murderer is Cui Yuanwai or Mrs. Meng, I have always been very confused, if Cui Yuanwai has an enmity with Song Zhe and wants to take this opportunity to kill him, it is possible. ”

"I ......", Cui Yuanhao just wanted to speak, but was interrupted by Nie Xiaohu waving his hand.

"This is just my conjecture, Cui Yuanwai should not panic, the same, this reason is also applicable to Mrs. Meng, so who is the murderer? In order to find out the relationship between the couple and Song Zhe, I sent Xiaoshi to Cui Yuanwai's house as soon as possible.

Although the results of the investigation were beyond my expectations, Cui Yuanwai and his wife did not have any holidays with Song Zhe, and everyone got along very well on weekdays, but this trip was not in vain, and Xiaoshi also brought me back a seemingly insignificant but crucial piece of information, that is, the relationship between Cui Yuanwai and his wife was not so harmonious.

According to the subordinates of Cui's house, Cui Yuanwai and Mrs. Meng have a bad relationship, and they often quarrel, as for the reason, it is nothing more than that Mrs. Meng has not been able to give birth to a son and a half daughter for many years, so Cui Yuanwai is very anxious, so he accepted a concubine last year. ”

During the speech, the afterglow of the corner of Nie Xiaohu's eyes never left Meng's face, and when he said this, Meng's body, who had been closing his eyes and chanting Buddha, couldn't help but tremble slightly, and the hand holding the Buddha bead was also clenched tightly.

Cui Yuanhao on the side also lowered his head, showing a complicated expression on his face.

Nie Xiaohu sighed slightly, shook his head slightly, and continued: "When I inadvertently found He Furong and Mrs. Meng chatting through the window in the hall, I suddenly thought of what He Furong said, which confirmed my conjecture, and the information brought back by Xiaoshi made me even more convinced that Mrs. Meng was the murderer of Song Zhe. ”

"Me? What did I say? He Furong said with a look of surprise.

Nie Xiaohu smiled slightly, "You said you watched the moon for a long time in front of the window last night. ”

“…… Ah, yes, what's wrong with that? He Furong frowned, completely confused.

"You must have seen something else when you looked at the moon, right?" , Nie Xiaohu sneered twice, "Through the back window of your room, it seems that you can just see the secret room in the backyard, right?" ”

"I... I didn't see anything", a panicked expression appeared on He Furong's face.

"You're not chatting with Mrs. Meng, but you're blackmailing her, right?"

"Nonsense! When did I blackmail her? That's chatting, we haven't seen each other for a long time, it's so easy to meet, what's wrong with chatting, can't you? He Furong pursed her mouth and pretended to be calm.

"I seem to remember when I asked you if you and Mrs. Meng knew each other, you said that you didn't know her, and you had never met before, right?" , Nie Xiaohu said in a weird way.

"Me! ......", He Furong was speechless for a while, and was speechless for a long time.

"What about the necklace? Mrs. Meng doesn't have baggage or anything like that, and I've searched her body, but she doesn't have that necklace? Cao Xiaohui interjected on the side and asked.

"My lord, the water is boiling!" At this time, Shopkeeper Feng walked in.

"Very well, you go and bring a basin of boiling water now, and by the way, bring a colander!" , Nie Xiaohu smiled and nodded.

Soon, Shopkeeper Feng brought a large wooden basin, which was full of steaming boiling water.

"Mrs. Meng, borrow your Buddha beads for use!" , Nie Xiaohu stretched out his right hand in front of Meng Shi's eyes as he spoke.

Meng Shi hesitated slightly, and finally handed over the black Buddha beads in his hand to Nie Xiaohu's hands.

Nie Xiaohu took the string of Buddha beads and looked at it, and then threw it into the wooden basin, everyone's eyes instantly focused on the wooden basin, only to see that as soon as the Buddha beads entered the water, the water surface immediately became pitch black, and after a while, a basin of clear water turned into black water, like a basin of ink.

"When I found a big bowl of ink under the table in the room where Cui Yuanwai and his wife lived, I suspected that there was something wrong with the Buddhist beads in Mrs. Meng's hand, and then I secretly counted them, no more, no less, exactly twenty-eight beads, exactly the same as the lost necklace, so I was even more convinced!"

Nie Xiaohu said with a smile, took the colander from the hand of the shopkeeper Feng, scooped it in the dark water, and then picked up the colander, and a string of white and flawless pearl necklaces appeared in front of everyone.

"Really!" , Cao Xiaohui almost jumped up.

"Is it really you?" , Cui Yuanhao pointed at Meng Shi and said tremblingly, "You... What are you doing this for? ”

"For what!"

At this time, Meng Shiyuan opened his eyes and glared angrily at Cui Yuanhao, "What do you say for?" Didn't the little fox just give birth to a son? You want to divorce me and make her the main room! ”

"I didn't!"

"Still lying! If I hadn't stumbled upon the book you've already written, I would still be in the dark! ”

Meng Shi shouted, and then hid his face and cried, "I am a woman, if you divorce me, what will I live on?" This necklace is enough for me to live for the rest of my life, and the reason why I did this was forced by you! ……”
