Zhang Xiuwen's eyes flashed with tears, and he choked up, "I...... I don't know."

Ma Hongwen had no pity for the jade: "Then I'll ask you something you can know." When there was a fire accident in Mr. Wang Wenhui's house, where was Wang Qianshan and what was he doing?"

"I don't know...... In those days, Wang Qianshan was rarely at home, nor did he go to the Chinese medicine clinic, and spent all day outside with Li Qian."

"Was the fire in the middle of the night or early in the morning?"

"Yes."

"What was the cause of the fire?"

"There was a power outage that day, and it was raining in the autumn, so the doors and windows were closed. At night, my father-in-law was repairing the sewer at home and accidentally moved the gas pipe, causing a gas leak, but he probably didn't know it. Before going to bed, I forgot to extinguish the candle. In the middle of the night, a fire broke out."

When the police were investigating Wang Yuange's social relations, they went to Wang Wenhui's old house.

Wang Wenhui's old house is a self-built house, with three floors, a clinic downstairs and people living upstairs. When gas became popular, gas pipelines were mostly laid along sewer pipes for such old houses.

After the fire, the old house was repaired, but it has been vacant, except for the furniture, the huge house only has the posthumous photos of Wang Wenhui and his wife, which is in line with the general role of the old house for living ghosts and not living people.

"After the fire accident, when did Wang Qianshan start to appear?"

Two tears finally burst out of his eyes, and Zhang Xiuwen choked up, "He...... He was the first person to notice the accident, and he was the one who called the fire."

"In the middle of the night, why did Wang Qianshan suddenly appear there?"

"He planned to elope with Li Qian, but his ID card was left at the clinic...... So I secretly went back and wanted to take my ID card away."

Everything can find a reasonable explanation.

Ma Hongwen suddenly said, "After the incident, did Wang Qianshan still refuse the police's routine proposal to conduct an autopsy on the bodies of Wang Wenhui and his wife?"

"The dead are greater. As the eldest son, if Wang Qianshan asks that the remains of his parents be kept intact and that they cannot be dismembered after death, the police have no reason to doubt such claims, and can only respect the wishes of the family."

"Wang Yuange's blind worship of Wang Qianshan can be described as a horse's head. Wang Qianshan made such a statement to the police, and Wang Yuan'e naturally had no objection."

"The accident happened in November 2001, and you just said that when you divorced Wang Qianshan, Wang Yuange was still studying. Therefore, at the time of the accident, Wang Yuan'e should not be at home, but at school. When he suddenly received the news that his parents had died in a fire accident, he was shocked and saddened, and he had to treat it as an accident without too much suspicion."

"Mr. Wang Wenhui has no deep hatred in his life, and he is also a hero of the country, and he has a good reputation among his neighbors and patients. It is unlikely that such a person will be killed or murdered. Moreover, the death of people in a domestic fire accident is a normal accident."

"Therefore, in the eyes of the police at the time, there is nothing suspicious that Wang Wenhui and his wife died in the fire."

"But what about you?"

"I have always asked you questions about the fire accident around Wang Qianshan, your emotions are very sad, does it mean that in your heart, you have always suspected that this fire accident was not an accident, but man-made, and the culprit is Wang Qianshan?"

"On one side is the in-laws, on the other side is the ex-husband, although this man betrayed you and made you sad, he is still the father of the child after all, and he is still the brother of Wang Yuange. The in-laws are dead, the children have no grandparents, and Wang Yuange has no parents. There is no need for a child to lose his father or his brother again."

"Besides, although you have this suspicion, you have no evidence."

"So, from beginning to end, from the time of the crime to the present, you chose to pretend to be deaf and dumb and ignore it?"

Zhang Xiuwen had already burst into tears, but he never said a word.

Ma Hongwen didn't intend to let her go, and continued in an almost cold tone, and his words were as cold as a knife, and he continued like a knife:

"As I said just now, Wang Qianshan is very likely to divorce you, and he and Li Qian will also go to confess to Wang Wenhui

。 You have not raised any objection to this. That means you have this suspicion too."

"If this assumption is true, Wang Wenhui will be furious and will undoubtedly resolutely oppose it."

"Knowing the son is better than the father, and knowing the father is also more than the son. Wang Wenhui's attitude must have been expected by Wang Qianshan. But he still decided to do this, so naturally he didn't plan to follow Wang Wenhui's will anymore and give up halfway. He didn't go to ask Wang Wenhui's opinion, but to announce to him that he was going to make decisions for himself."

"It's like when Wang Wenhui announced to Wang Qianshan that he didn't have to go to university. The difference is that this time the declarant and the proclaimed have reversed roles."

"Whether it is from your feedback just now, or the information we originally had, Wang Qianshan has always been worried about his inability to go to university. And the initiator of all this is indeed Mr. Wang."

"Therefore, for Wang Qianshan, challenging his father's authority and violating his father's will not only gives him the pleasure and satisfaction of revenge, but also a sense of ritual and accomplishment that I have controlled my own destiny."

"One is determined to abandon his wife and children, and the other is resolutely opposed. Fierce conflicts and contradictions inevitably erupted. In this process, Wang Qianshan's dissatisfaction and resentment against his authoritarian and domineering father accumulated for many years were also detonated in an instant like a volcano that had been accumulated for many years."

Then, Ma Hongwen suddenly changed his words: "I heard that in the past, there were tomb robbers who said that 'father and son gang said.'"

"When robbing a tomb, it is often necessary for one person to guard the outside of the tomb and one person to enter the tomb. But many times, when the people in the tomb are in distress, the people outside the tomb do not enter the tomb to save people in desperation, but immediately flee from the wind."

"In order to prevent this from happening, the grave robbers have gradually developed into fathers and sons. Fight tiger brothers, go into battle father and son soldiers. In that way, the members of the tomb robber gang should trust each other, right?"

"Oh, no, there will still be cases of abandoning partners."

"The father went into the tomb, and the son stood outside the tomb. But the father was in distress inside, and the son still saw that he would die and would not save him, so he ran away. Even after hanging out all the belongings inside, the son wanted to keep it to himself, so he blocked the entrance outside, and sealed his father alive inside."

"But the living must not suffocate their urine. They quickly found a solution to the problem. When robbing the tomb, he arranged for the son to enter the tomb, and the father kept watch outside the tomb, and made it an iron rule."

"Heh, in this way, there really has never been a human tragedy of abandoning a partner or killing father and son."

Then, Ma Hongwen looked straight and got back to business: "Tiger poison does not eat the son, but the son can eat the father. In the fierce conflict between the father and son, Wang Qianshan most likely committed a crime of passion and killed Wang Wenhui. If you don't do it, if you kill your father, you can kill your mother as well."

"After the fact, the fire accident will be caused again."

"Wang Qianshan is really a smart man. A fire can not only burn all traces of the scene, but also perfectly cover up the cause of the death of Wang Wenhui and his wife as an ordinary accidental death."

"In the eyes of the police, in the eyes of outsiders, a fire is nothing to make a fuss about, let alone suspect that father and son are killing each other."

The interrogation room immediately fell into deathly silence.

Zhang Xiuwen let the tears roll down.

After a long time, Zhang Xiuwen choked up and said, "I'm ...... Not lying."

Ma Hongwen's pupils shrank: "No one said you lied. Why do you want to emphasize that you're not lying, and don't question me for making up the story?"

Zhang Xiuwen still responded with silent crying.

"Because, in your heart, you have the same opinion as I do. That's what I said earlier."

"You certainly weren't lying. What you tell me is most likely what you see, or what you know. The power went out that day, and Wang Wenhui used candlelight to repair the sewers at home at night after sending all the patients away, which should be true."

"In the process of repairing the sewer, I accidentally damaged the gas pipe, causing a gas leak. This should have been the result of the investigation of the fire at the time. Whether it's the king or not

The two brothers of Qianshan Wang Yuan'e, or you, have no reason to question the police's results, and will only be convinced."

"The question is, was the damage to the gas pipeline accidentally damaged by Mr. Wang Wenhui, or was Wang Qianshan damaged it on the basis that Wang Wenhui had indeed repaired the sewer after the incident? Who knows?"

"As for Mr. Wang, he forgot to extinguish the candle before he fell asleep? Shh Wang Qianshan only needs to move the bodies of his parents to the bed, and then light a candle on the bedside table or on the living room dining table, while he himself stays outside the house, waiting for the leaked gas to reach a certain concentration and the fire breaks out in the house, and then call 119 to call the police."

"Of course, while waiting, he had enough time to pick himself up, so that he could not see any signs of a fight with someone."

"Just in case, Wang Qianshan must stay outside the house, and he must also call the police himself."

"Because he wasn't sure if anyone in the neighborhood would suddenly wake up at night, or wake up to a burning fire, and then find out about the fire, and kindly rush over to put out the fire."

"I'm not sure if the firefighters will find any clues when the fire is extinguished."

"For the sake of fire alarm, out of working practice, after extinguishing the fire, he will consult the family members, and when he wants to autopsy the body of the deceased, he can clearly refuse at the first time."

"I have to say that Wang Qianshan is very lucky. On that day, there were no accidents against him, and no one questioned what seemed to be a 'normal' accident."

"But you're different, you've always had doubts about this fire, but you've always buried it in your heart."

"I'm curious, after so many years, there is such a secret buried in my heart, are you tired?"
