The street houses and the east and west wings in the courtyard were all dark, but the main house on the north side was brightly lit, and there were a few voices in it who were noisy and excited.

"Stationmaster, what should I do?" Liu Mancang turned his head and asked Du Chenghu for instructions.

"Leave two team members to guard at the gate of the courtyard, and the others will rush into the main room to arrest people first!" Du Chenghu commanded.

"Yes!"

Liu Mancang left two team members to guard the gate of the courtyard, and then he came to the door of the main house first, raised his feet and kicked the door open, and then rushed in with two guns in his hand, and the others followed.

But when they rushed in, they were a little surprised. I saw Gu Siqiang holding a cigarette, sitting on a bench, and a few people shouting and drinking around a table of eight immortals to push pai gow enthusiastically.

What's going on? Didn't Gu Siqiang sneak out to deliver the news? How can it be pushing pai gow in the room with someone? It's not the same as it was envisioned!

However, the accident was an accident, Liu Mancang's movements did not pause at all, and led the team members to pounce, pressed Gu Siqiang on the table of the Eight Immortals, and handcuffed him on the spot. As for the other people at the Eight Immortals' table, they were forced by the muzzle of the black hole to stand at the base of the wall with their heads in their hands, and after being searched to find out that there were no weapons, they were ordered to squat down next to the wall.

Du Chenghu waited until Liu Mancang controlled all the situation in the room before he stepped in.

When Gu Siqiang saw Du Chenghu coming in, he shouted continuously, "Stationmaster, stationmaster, is there any misunderstanding?" Why do you want to arrest your subordinates? ”

"Why did you arrest you?" Du Chenghu sneered and said, "Gu Siqiang, don't you know it yourself? ”

"Stationmaster, my subordinates really don't know!" Gu Siqiang shook his head desperately, looking extremely innocent.

"Don't know? Then tell me, at three or four o'clock in the morning, I don't sleep in the dormitory, what are you running out for? Du Chenghu said.

"My subordinates tossed and turned in bed, thinking that so many things had happened tonight, it was too unlucky, and finally I couldn't sleep when I saw myself, so I thought about coming to Boss Li to gamble two handfuls and win some money!" Gu Siqiang said.

"Huh!" Du Chenghu laughed fiercely, "Gu Siqiang, did you really deceive Lao Tzu as a three-year-old child?" Do you think Lao Tzu will really believe your lies? ”

"Stationmaster, my subordinates really didn't say a word of lies! If you don't believe it, you can ask Boss Li and see if his subordinates came to gamble with them! Gu Siqiang said.

At this time, Lin Jiangbei walked in from the outside and whispered a few words in Du Chenghu's ear.

Du Chenghu nodded, and looked at Gu Siqiang again, "Gu Siqiang, what did you do when you got here, besides gambling with them?" ”

"Stationmaster, I came here to gamble with them, except for gambling, I didn't do anything!" Gu Siqiang shouted aggrievedly.

"Nothing? I see that you don't shed tears when you don't see the coffin! Du Chenghu shook his head and said to Liu Mancang, "Mancang, escort him out for me!" ”

So Liu Mancang escorted Gu Siqiang and followed Du Chenghu and Lin Jiangbei to the courtyard, Gu Siqiang saw the lights in the street house on the south side of the courtyard turned on, and a panicked look flashed in his eyes.

Lin Jiangbei asked Liu Mancang to escort Gu Siqiang into the street room, turned his head and said to Gu Siqiang: "Team Leader Gu, have you ever been to this room?" ”

"No, I don't have it at all!" Gu Siqiang shook his head vigorously and said, "After I came, I went directly into the main room to push pai gow with Boss Li!" ”

"Hehe, yes!" Lin Jiangbei smiled faintly, stretched out his hand and pointed to the black telephone on the table in the room, and said, "Then Team Leader Gu must not have touched this telephone." ”

"What telephone? Team Leader Lin, if you don't bring me in, I don't know there is a telephone in this room! Gu Siqiang said.

Seeing Gu Siqiang's stubborn mouth, Lin Jiangbei snorted contemptuously.

He walked around the courtyard just now and found that Gu Siqiang's smell was not only from the main house, but also at the door of this street. Then he entered this street house and found this telephone, and he also smelled the smell left by Gu Siqiang on the telephone, indicating that Gu Siqiang had used this telephone.

Although it is said that the smell can help Lin Jiangbei track it, it cannot be used as evidence, but this does not mean that Lin Jiangbei has no way to prove that Gu Siqiang used this telephone.

Lin Jiangbei put on his gloves, gently picked up the microphone of the telephone, and took a few breaths with his mouth. Soon, several fingerprints appeared on the black surface of the microphone, one of which was particularly clear.

Lin Jiangbei looked at it carefully for a while, and found that this was a fingerprint of his left thumb, so he reached out and took out a small mirror from his pocket, grabbed Gu Siqiang's left thumb and pressed it vigorously on the mirror, and then sighed lightly on the mirror, so the fingerprint of Gu Siqiang's left thumb clearly appeared on the mirror.

Lin Jiangbei placed the small mirror next to the microphone, asked Liu Mancang to bring Gu Siqiang up, pointed to the fingerprints of the two thumbs on it, and said, "Gu Siqiang, stare at your eyes and take a closer look, are these two fingerprints exactly the same?" ”

Gu Siqiang lowered his head with a pale face.

Du Chenghu slapped Gu Siqiang in the face, "Eat things inside and outside!" Hurry up, who is the call for? ”

Gu Siqiang gritted his teeth and didn't say a word.

As the leader of the torture team at Hangcheng Station, Gu Siqiang certainly understands how the Intelligence Department treats betrayers. If you grit your teeth and don't say anything, you can still save your life temporarily, and once you tell everything, then it means that your life is coming to an end.

"Take Gu Siqiang, as well as the guys in the main room, all of them to the Chai Mu Lane Detention Center and torture them severely!" Du Chenghu gritted his teeth and waved his hand to let Liu Mancang escort Gu Siqiang out, and then looked at Lin Jiangbei with a sigh and said: "Jiangbei, it seems that Gu Siqiang, the king of the eight lambs, used the phone to spread the news, and now it will be troublesome!" ”

"yes, I'm in trouble!" Lin Jiangbei sighed lightly, bowed his head and admitted his mistake to Du Chenghu, "Inspector General, I'm sorry, it's the students who didn't think about it and were negligent, I didn't expect Gu Siqiang to be so cunning......"

It is really Lin Jiangbei's negligence, because according to the regulations of the Intelligence Department, all the units under the Hangcheng Station, including the secret torture department, have special telecommunications staff to listen to them, and in the early hours of the morning, there will be no public telephones on the street for the use of the poisoners, so Lin Jiangbei thinks that after the poisoners sneak out, they will definitely find someone to deliver the news, and then they can follow the vine and find the melon......

But he didn't expect that Gu Siqiang would go to the casino and use the phone here to pass on the news.

What's even worse is that there is no way to find out who Gu Siqiang called to him.

Because in 1929, Zhejiang Provincial Telephone Company invested 230,000 US dollars to introduce 7-A rotary 3000-door automatic exchange to Belgium, the project was completed and put into use in April 1931, Hangcheng urban area has since abolished the manual telephone exchange, with a 4-digit dial-up automatic telephone, which is a huge leap in the history of Hangzhou telecommunications, but at the same time caused a huge problem to the telecommunications personnel of the intelligence department.

Because the automatic telephone exchange at this time belongs to the stepper telephone exchange, it is an automatic telephone exchange composed of selectors and relays. Its working principle is to replace the wiring action of a manual telephone exchange operator with a mechanical action. When the user dials a number, the corresponding selector in the switch changes the connection position step by step with the pulse current sent out during dialing, and the telephone line between the calling and called users is automatically connected.

This means that even a telephone company cannot query the caller ID and the called number.

Only the internal telephone of some units is arranged with a special manual operator to transfer, so that the number that is dialed out recorded by the manual operator can be found, and for the incoming call, the manual operator can only record who is looking at what time it is, and the content of the call can also be recorded by listening, but for the phone number that is called, the manual operator is also unable to know.

In short, such a large paragraph is explained, that is, in one sentence, even if the power of the telecommunications personnel of the Intelligence Department is used, there is no way to find out who Gu Siqiang's call is to, unless they can pry Gu Siqiang's mouth open!

The so-called 100 dense and one sparse.

Lin Jiangbei thought that he had thought it through enough, but he still didn't expect that he would be negligent in this place.
