Ning Zhiheng and the others soon came to the residence of Yi Dong's family, which is an independent mansion, although the area is not large, but it is already a rare residence in Chongqing.

The yard was cleaned up from the inside out, and it was obvious that the hostess was a neat housewife.

When I first saw Yi Dong's wife, this woman was about thirty years old, her face was delicate but she couldn't hide a trace of sadness, she looked at Yu Cheng with a faint expression, and there was a seven or eight-year-old girl hiding behind her, this was Yi Dong's daughter.

Yu Cheng stepped forward and said softly and kindly: "I'm really sorry, Mrs. Yi, I still have to ask you again today about some things about Mr. Yi." ”

Mrs. Yi said with some hesitation: "Team Leader Yu, haven't you asked several times, I have said everything I should have said, it has been more than a month, you give me a truth, is there a problem with my husband's death?" Wasn't he killed by the Japanese? ”

This Mrs. Yi is also a shrewd person, and from Yu Cheng's several contacts, it can be seen that the headquarters of the Military Administration does not agree with Yi Dong's death, but Yi Dong was bombed to death by Japanese planes, and the whole process is clear, and she can't think of what the problem is.

Yu Cheng looked at Mrs. Yi and didn't know how to answer for a while, and Ning Zhiheng behind him said: "Mrs. Yi, Mr. Yi is really important to our Military Command Bureau, and his death has surprised the military commanders very much, so we have to be cautious about the cause of his death, but don't worry, this is the last investigation, and we will not bother you again after that." ”

Mrs. Yi looked up at Ning Zhiheng, this tall young man had a serious and solemn face, she nodded, and promised: "Where, don't talk about bothering, the bureau takes care of our mother and daughter very much, I still know what to do, you can ask if there is anything." ”

Mrs. Yi let a few people into the house and sat down, poured tea for them, and Ning Zhiheng asked: "We just want to ask today, on the day Mr. Yi died, did he have any abnormal behavior, although it was the 16th and a rest day, but we know that he usually works overtime, why didn't he go to overtime that day?" ”

Mrs. Yi replied softly: "My husband is usually too busy with work, he rarely accompanies us and my mother, it was a rest day, and he was in a rare good mood during that time, and he was going to accompany us to a movie, so he didn't go to work." ”

Ning Zhiheng asked strangely, "Watching a movie?" But you didn't go in the end, did you? ”

Mrs. Yi sighed and said sadly: "This is fate!" If we went, my husband might not have been killed by the Japanese, and when he got up in the morning, my husband was a little uncomfortable, and he was dizzy after walking a few steps, which is also his old problem, and he usually took some medicine to rest.

So we didn't go out, I gave him some medicine at home, and lay down on the bed to rest, but it didn't take long for the Japanese plane to come, and he refused to go to the bomb shelter as before, so I had to leave with my daughter, who knew that this time the luck was so bad..."

After saying that, Mrs. Yi's tears could no longer be held back and she sobbed softly.

Sure enough, there was a problem, Ning Zhiheng and the others' eyes lit up, and they hurriedly asked, "When did Mr. Yi feel unwell, was it before breakfast or after breakfast?" ”

Mrs. Yi recalled carefully and replied: "It was before breakfast, he got up a little dizzy early in the morning, but it was not bad, it was not painful or itchy, he was dizzy after standing for a while, and he was fine after resting more." ”

"Has Mr. Yi ever had this symptom before?"

"I've had a few times before, but I've seen the doctor in the bureau, and the doctor said that it is because of the neurological problems caused by excessive use of the brain and anxiety, and it would be good to rest and take some medicine."

"Is Mr. Yi anxious during this time?"

"No, he was in a good mood those days, saying that things were going well at work, and the bureau also rewarded a sum of money, otherwise he wouldn't be in the mood to take our mother and daughter out to watch a movie."

Ning Zhiheng and Yu Cheng glanced at each other, and then asked, "Did Mr. Yi eat anything the night before the accident?" ”

The Japanese did things to Yi Dong, which was nothing more than eating and drinking, and since they felt uncomfortable when they got up in the morning, it was very likely that they had been hit the night before.

"The night before?" Mrs. Yi thought about it carefully, and then said, "The dinner I had at home the night before was all some of the meals I fried, nothing special, at most I fried a few more appetizers for them to drink. ”

They? Ning Zhiheng suddenly perked up, and he asked in a deep voice, "Did Mr. Yi drink that night?" Who are you drinking with? ”

"Who else? Gu Zhengqing, the two of them often had a few drinks together, and that night I had to come over to drink with my husband, so I had to fry some snacks, and they chatted until late. ”

Gu Zhengqing? Ning Zhiheng's mind immediately showed a figure, it was the man in his early thirties that he saw in the decipherment room today, who had a friendly attitude towards Ning Zhiheng, and was not colder than others.

Yu Cheng opened his mouth to explain: "This Gu Zhengqing and Mr. Yi both came back from studying in Japan, and they are about the same age, so their relationship is naturally closer. ”

But Ning Zhiheng disagreed, he listened to Mrs. Yi's tone, as if he didn't like this Gu Zhengqing, so he continued to ask: "Why did this Gu Zhengqing come to Mr. Yi for a drink, just to chat?" Say what's the matter? ”

Mrs. Yi shook her head and replied, "I don't drink again, so I went back to the house early to rest with the children, as for what they said, I don't know, but this Gu Zhengqing is not a serious person, and I rarely talk to him." ”

When Gu Zhengqing was mentioned, Mrs. Yi's tone was very displeased, and it could be seen that she did not have a good impression of Gu Zhengqing.

"Mrs. Yi seems to be very dissatisfied with Gu Zhengqing, is there something he disrespects Mrs. Yi?"

Ning Zhiheng knew from the investigation information that Gu Zhengqing had always been single and had not talked about a girlfriend, would he have any thoughts about Mrs. Yi, which would cause Mrs. Yi's disgust.

Mrs. Yi shook her head and said: "Many people know about this Gu Zhengqing, I don't say right or wrong after I am not a person, you can just inquire at will." ”

The implication is obviously that she doesn't want to say more, and it can be seen that this Mrs. Yi is somewhat cultured and very cultured, no better than an ordinary woman with three aunts and six mothers-in-law.

Ning Zhiheng was not embarrassed by a strong man, and then asked, "Then Gu Zhengqing has any abnormal performance compared to usual?" Is all the food for dinner from your house? ”

"It's no different, it's the same as usual, but every time he comes to drink with my husband, he brings a bottle of good red wine, my husband loves to drink, when the family was good before, my husband had the habit of drinking red wine, and then the war was chaotic, the Yi family was defeated, and we ran around, after coming to Chongqing, the conditions here are more difficult, a bottle of good red wine, we can't afford it."

Mrs. Yi's words immediately attracted everyone's attention, and Ning Zhiheng asked, "The red wine that Mr. Yi drank was brought by Gu Zhengqing?" ”

"Yes, bring it every time, the Gu family has a good background, and you can always get some good things, no better than us." Mrs. Yi confirmed.

"Then when eating, does Gu Zhengqing also drink red wine?"

"He doesn't drink it, he likes to drink white wine, and red wine is specially prepared for my husband."

Ning Zhiheng nodded, he had some bottom in his heart, and then he asked some more questions, and then got up to say goodbye.

The group left Yi's house and discussed today's investigation results as they walked.

Yu Cheng opened his mouth and said: "I was negligent before, but now it seems that Gu Zhengqing is a traitor, he is Yi Dong's friend, he naturally knows that Yi Dong suffers from claustrophobia, and he also knows that he has dizziness, and he is a core member of the decipherment team, and he also knows that Yi Dong began to decipher the Japanese military code, so he began to plot the murder of Yi Dong."

On the night before the rest day, I took the opportunity to drink at home, and made my hands and feet in the red wine, and let Yi Dong drink it, causing Yi Dong's old illness to recur, Yi Dong was unwell, and he did not doubt him, so he could only rest in bed at home as usual, and then the Japanese bombers flew over, taking advantage of the sound of the siren, when everyone hid in the bomb shelter, Gu Zhengqing arranged for his accomplices to arrange the bombing signs, and Yi Dong refused to enter the bomb shelter as usual because of claustrophobia, and was bombed to death by the bombers. In this way, everyone thought that Yi Dong died accidentally, and if he got rid of Yi Dong unconsciously, Gu Zhengqing could continue to lurk peacefully, it was really a good calculation, but unfortunately it was discovered at the beginning, and now it is still in our hands. ”

Ning Zhiheng completely agrees with Yu Cheng's judgment, and at present, Gu Zhengqing's suspicion is too great.

He suddenly remembered something, turned his head to Bian Deshou and asked, "Old Bian, just now Mrs. Yi said that Gu Zhengqing was unbearable, and he was unclear with his father's woman, do you know what the matter is?" ”

Bian Deshou is the chief steward of these deciphering experts, and is responsible for taking care of the daily life of these people, so he should also know something about this.

Bian Deshou heard Ning Zhiheng's inquiry, and said: "In fact, it is not as serious as Mrs. Yi said, these are those three aunts and six women who are good at gossip chewing their tongues, the thing is like this, Gu Zhengqing's father worked in the Ministry of Finance, and more than half a year ago he fell in love with a young woman who fled from the army, this woman's husband was killed by the rebels on the way to Chongqing, and he was alone in Chongqing without relatives, and then he was forced to make a living, so he committed himself to the Gu family, and government officials could not take concubines, so there was no name, But later, for some reason, it was rumored that Gu Zhengqing had something to do with this woman, Gu's mother was threatening, so she drove this woman away, Gu Zhengqing also had an awkward relationship with his father for a long time, and then slowly eased up, in fact, according to me, his father is disrespectful to the old, and it is not a good way. ”

Ning Zhiheng frowned, he didn't care about the shortcomings of these parents in the market, but Gu Zhengqing was a person, and he had to try his quality.
