Ning Zhiheng came to the window again, looked up and looked around, and kept thinking in his mind.

This time the situation is really strange, there are many problems that can't be explained, but the murderer is Gu Zhengqing's upline and his lover, which shouldn't be wrong.

Before he asked Tai Cheng and Bian Deshou, both of them said that Gu Zhengqing had never been in contact with improper women, and only had an entanglement with a woman in the family half a year ago, which was just right in time.

And I have also judged that according to Gu Zhengqing's situation, if the Japanese want to rebel against him, they will generally work women.

So these lines are connected, can it be explained that the woman who was taken in by Gu Zhengqing's father is likely to be a Japanese spy, she entered the Gu family through a series of arrangements and Gu Zhengqing's father, and then came into contact with Gu Zhengqing, and then rebelled against Gu Zhengqing with her beauty, but then her relationship with Gu Zhengqing was discovered, and the female spy left the Gu family, but she still secretly kept in touch with Gu Zhengqing.

In fact, Ning Zhiheng was more inclined to have a personal affair with this female spy at first, until the female spy left the Gu family, they broke the connection and borrowed room 202 of Huaqing Hotel to continue the private meeting, and then Gu Zhengqing slowly became unable to extricate himself and became an accomplice of the Japanese.

As for Yu Cheng's previous investigation, he did not find a contact place at Huaqing Hotel, or a place for a date, which is also easy to explain.

After all, before Yidong's air raid, the decipherment room was calm and there were no problems, of course everyone would not notice Gu Zhengqing's abnormality, nor did they investigate and track it, and the frequency of his contact with the line was very small, and even only once in half a month, so as long as Gu Zhengqing was careful, it would be difficult for others to find out the location of this contact.

After the air raid, Gu Zhengqing no longer contacted the upline, nor did he come to the Huaqing Hotel, so Yu Cheng's investigation did not find out here, until Ning Zhiheng used the method of startling the snake and forced Gu Zhengqing to contact the upline again, which led his attention to the Huaqing Hotel and exposed the location.

Now what Ning Zhiheng has to do next is to investigate this woman from the mouth of the Gu family and find her photo, if the Gu family does not have a photo, then Ning Zhiheng will depict it himself, this must be a very important clue.

Ning Zhiheng turned around and waved his hand to Cheng, and Yu Cheng hurriedly took a few steps forward and came to Ning Zhiheng.

"Seated?"

"Did Gu Zhengqing make a phone call to contact the outside world at Gu's house?"

"No, definitely not!"

"Did his family behave unusually, or had any contact with the outside world?"

"No, in the more than an hour after you left, the Gu family didn't make any phone calls, only an incoming phone call, which was to invite Gu's mother to play mahjong tomorrow, and no one in the Gu family went out, so during this time in the Gu family, Gu Zhengqing should not have contact with the outside world."

"Did he make any stops on his way here, or did he come into contact with the outside world?"

"No, he came directly to the Huaqing Hotel and entered room 202, without stopping halfway, and there was no sign of contact with outsiders."

"That's weird!" Ning Zhiheng pondered for a moment and said, "We decided on his transfer on an ad hoc basis, Gu Zhengqing couldn't have known in advance, he didn't have contact with the outside world after he went home, and he didn't stop on the way here, so how could he notify his upline to connect, can't he know his upline as soon as he appeared in room 202, right?" ”

When Yu Cheng heard this, he also said suspiciously: "I also had some suspicions before, there is a possibility, that is, they have an inside line in the hotel, as soon as Gu Zhengqing comes to Huaqing Hotel, this inside line will notify his upline." ”

Speaking of this, Yu Cheng's eyes looked outside the door, the hotel manager and the waiters stayed outside the door now and did not dare to leave, waiting for Ning Zhiheng's instructions.

Ning Zhiheng shook his head and said: "It doesn't make sense in theory, it stands to reason that the connection between them, the fewer people who should know about it, the better, and it is not safe to have one more person in the middle."

Moreover, according to my judgment, Gu Zhengqing was killed by his upline, and this upline should be a woman, if they have an internal response in the hotel and want to kill Gu Zhengqing, they will directly arrange for the internal response to attack Gu Zhengqing, and there is no need for this upline to take the risk in person. ”

"It was a woman who killed Gu Zhengqing?" Yu Cheng said in surprise, he didn't know why Ning Zhiheng judged it like this, but this explanation was too bizarre.

Ning Zhiheng nodded and said: "Yes, it shouldn't be wrong, I'll explain it to you later, now what I want to know is how Gu Zhengqing notified his upline to come here to meet, they have met here many times, there must be a way to contact each other, but we can't detect it for a while." ”

Yu Cheng also said with a headache: "You can't always have clairvoyance, as soon as you see Gu Zhengqing coming here, she will come over to meet her, right?" ”

Yu Cheng's words made Ning Zhiheng's heart move, maybe it was really what he saw with his eyes!

He suddenly looked out the window again, and through the window he saw the large residential area across the street.

From here, he could clearly see the light on the other side, and the opposite side should be the same, and he could also see the windows in this room, even if his eyesight was weak, he could use a telescope to easily see the windows of room 202.

It seems that he always thinks things are complicated, in fact, all this is not so complicated, Yu Cheng came to the room and turned on the house light, and opened the window, if his upper line lives in the residential area opposite, it can be seen with binoculars or even with the naked eye, so he can come to meet.

Could that be the case? Ning Zhiheng didn't dare to draw conclusions for the time being, but this idea was very feasible, and he had to find some evidence to improve it.

Ning Zhiheng thought of this, turned his head to Cheng and said, "Send the body back to the second place, and the manager and waiter will also take it back together, and then make a decision when everything is clear." ”

Ning Zhiheng was still not sure if his judgment was accurate, so as long as there were suspicious people, he had to bring them back to prevent anyone from slipping through the net.

Yu Cheng nodded and agreed: "Yes, I'll deal with it." ”

"Is there anyone left in the Gu family?"

"Stay, I arranged a team to watch near Gu's house."

"Start immediately, arrest all the people in the Gu family and send them to the second place, I want to ask."

"Yes!"

Ning Zhiheng didn't stay any longer, walked out of the hotel, and rushed back to Operation 2 with his guards.

Back in his office, Ning Zhiheng sat on his chair and carefully recalled the investigation process of this day.

Today's case suddenly changed, Gu Zhengqing, who was originally going to connect, was categorically killed by his upline, and there was no warning in advance.

And Ning Zhiheng's investigation of Gu Zhengqing was also decided on an ad hoc basis, and it was impossible for the Japanese to get the news in advance.

What went wrong? There must have been a mistake in tracking and surveillance, Gu Zhengqing went out of the decipherment room, and only went to three places, one was the dormitory assigned to him by the Military Command Bureau, but in this place, Gu Zhengqing barely stayed, and it was also under Ning Zhiheng's surveillance.

The second location is Gu's house, he stayed in this place for more than two hours, and Ning Zhiheng also arranged personnel to follow and monitor the surroundings, and it is also possible that he will be detected in the process.

Therefore, Ning Zhiheng arrested everyone in the Gu family first, and then carried out the screening work.

The third location is Huaqing Hotel, as judged before, Ning Zhiheng does not think that there is a problem inside the hotel, so the problem should be outside, what is the problem?

Ning Zhiheng only felt that everything was in a mess, and all kinds of judgments and speculations were full of his mind, and he couldn't come up with an answer.

At this time, Zhao Jiang came to report, Shao Wenguang came to ask for a meeting, Ning Zhiheng nodded, and motioned for him to come in.

Shao Wenguang walked in quickly, holding a document in his hand, and said in an excited tone: "Seat, I thought you had gone home to rest, but I just heard the noise, and I realized that you were still there, so I rushed to report to you." ”

Ning Zhiheng smiled slightly and said, "I guess I'm going to stay up all night again today, if there is anything, you can come to me at any time, what, look at your appearance, is Ji Yongyan speaking?" ”

"Spoke!" Shao Wenguang hurriedly replied, and he stepped forward to put the interrogation record on Ning Zhiheng's desk.

Shao Wenguang's words made Ning Zhiheng also feel refreshed: "Well done, I won't read the record, you hurry up and talk about it!" ”

Shao Wenguang coughed lightly and replied: "It's really not easy, since last night to now, I have exhausted all my means, this Ji Yongyan has stayed up for twenty hours, and he was almost made an idiot by the electric chair, and finally spoke." ”

"Getting to the point!"

"Yes, Ji Yongyan's original name is Yoshida Takayu, codenamed Montenegro, and he is a member of the former Shanghai Special High School, which is completely consistent with the information you gave me, we have already mastered his activities in the leak case, I will not go into details, the focus of my interrogation is mainly on his line.

Half a year ago, Yoshida Takasuke's relationship was transferred to the Military Intelligence Department of the Japanese Central China Dispatch Army, and the one who woke him up was a senior agent codenamed 'Volcano', but this Volcano is not his upline, there is no contact between them, except for seeing each other when they woke up, they have never seen each other again. ”

"Volcano? Montenegro? It's very interesting! They have also met? ”

"I've met once, but Ryuyu Yoshida's way of working has nothing to do with the volcano, after waking up, he sends a one-way message every ten days to confirm safety, and the rest of the time is silent, waiting for Xia Bin's contact."

"It seems that the volcano is only responsible for waking up the group of Yoshida Takayu and Xia Bin, and does not directly lead them, so how did the defense plan of northern Gan pass it on?"

"Dead mailbox, they pass it the way they do it!"
