"Got an emergency?" After Ma Chunfeng entered the door, he asked first.

Fang Buwei handed over the file in his hand and said the suspicious points he had discovered.

When Ma Chunfeng saw the details that Fang Buwei said, he was surprised: "I didn't even find out?" ”

Fang Buwei paused and then said: "According to Zhao Shirui's investigation, the whereabouts of this chief steward have been very fixed for a few days, and he has always been at the headquarters of Sihai Company. I guess he contacted Li Fengnian at that time......"

"Hiding the phone line, it's impossible!" Ma Chunfeng analyzed, "The telephone bureau can find it out as soon as you check it." Hiding a radio station will work...... It is not excluded that there are messengers in the middle! ”

"It's useless to keep track of this big steward!" Ma Chunfeng said, "He is basically in Sihai Company, and the number of people who come in and out of Sihai Company every day is not a small number, and it is impossible to tell who is going to find him!" ”

Ma Chunfeng pondered for a while and then said, "Unless you catch him back!" ”

Fang Buwei shook his head without thinking about it: "This is the most undesirable!" I estimate that as soon as we grab him with the front foot, Li Fengnian will know it with the back foot......"

"Who are you going to arrest back......" Before Fang Buwei's words were finished, the door was pushed open with a "bang", it was not Gu Zhenlong, who else.

Fang Buwei secretly said badly, he wanted to give Ma Chunfeng a look, but he didn't want Ma Chunfeng to directly hand the scroll in his hand to Gu Zhenlong.

"Qi Zhenjiang didn't find out the previous contact channels between Li Fengnian and his subordinates, so Fang Buwei deduced that they secretly had other contact methods......

Gu Zhenlong took it and glanced at it, and threw it to the side.

"Isn't it normal for Li Fengnian to take such precautions?" Gu Zhenlong asked rhetorically.

That's true.

There are only a few counter-espionage methods in this era, and if Li Fengnian is really the spy leader of Japan's special high class, it is impossible to think of it.

"As a last resort, it's better not to touch Li Fengnian's subordinates!" Fang Buwei said, "After so many temptations, it's time for Li Fengnian to show up!" ”

"Again, we can wait, but the chairman can't wait!" Gu Zhenlong shook his head and said, "If Li Fengnian is really in Shanghai, then send people from Shanghai to arrest him, if he is in Nanjing, he will not hesitate to close the city again, and he will be dug out, but first of all, determine where he is?" ”

Fang Buwei sighed, Gu Zhenlong was still unwilling to wait so passively.

Fortunately, Gu Zhenlong did not order himself to arrest people now.

But if Li Fengnian doesn't show up again, and he doesn't find out his exact whereabouts, Gu Zhenlong will have to take this step sooner or later.

I don't think I can wait for it to get dark today.

Fang Buwei racked his brains, thinking that he could find some clues from somewhere.

When he saw the telephone on the desk, his heart struck.

If you are Li Fengnian, you don't have to be so troublesome at all.

What spy boss doesn't know some of the means of compiling code?

Even if you can't, there will definitely be similar talents around you.

If Li Fengnian had agreed with the steward in advance, and the conversation would be in code when he called, who would be able to hear it?

Although Qi Zhenjiang is a master of telecommunications, when he was arranged to listen to the phone, it was already yesterday at noon, and the chief steward had already arrived at the restaurant.

Fang Buwei immediately expressed his conjecture, Gu Zhenlong immediately ordered the telecommunications department to closely monitor all the calls of Sihai Company, and asked Qi Zhenjiang to report back to the headquarters quickly.

Qi Zhenjiang was responsible for the telephone monitoring of the headquarters of Sihai Company.

Half an hour later, Qi Zhenjiang brought all the records of several phone calls at the headquarters of Sihai Company in recent times.

Fang Buwei focused on finding the record of the phone in the manager's office.

Looking at the list, the objects of the chief steward's communication are freight yards, stations, docks, various trading houses and business partners, the number is not large, but there is no regularity at all.

The telecommunications department had only arranged for the telecommunications department to monitor the phone at noon yesterday, so only the calls that had been recorded for more than 10 hours had been recorded.

The chief steward only went back in the early hours of the morning, and there was no recording of the phone in the manager's office.

The number of conversations on the other phones was not much, so Fang Buwei directly asked Qi Zhenjiang to play it again.

Most of the content is short and clear, and it is all wording from normal business dealings.

Gu Zhenlong even summoned He Qingnan to listen to it, and there was no Li Fengnian among them.

Fang Buwei asked Qi Zhenjiang again for advice on code language.

"It's about the same nature as the Telegram cipher!" Qi Zhenjiang pondered for a while and then replied, "Everything changes, no password can be separated from numbers, as long as you keep an eye on this, you can ......"

Fang Buwei explained to Qi Zhenjiang again, and the next phone call monitoring should focus on this point.

As a result, less than two hours after Qi Zhenjiang went back, that is, shortly after dawn, Qi Zhenjiang had a reply here.

The chief steward had just received a phone call, and the specific content was that the steward of the firm had asked him for instructions on the details of the transportation of a batch of goods.

It is a batch of raw silk purchased by Sihai Commercial Bank from the local area and the surrounding area, which will be transported to Shanghai through the river through the transportation company.

Half of the content that the chief steward arranged for his subordinates was numbers.

There is the amount of cargo, the length of the route, the number of people escorted, the number of weapons required, and the estimated time and date of arrival.

There is even the number of points made by the personnel at each inspection station along the way, which is simply meticulous to the extreme.

Just discussing the purchase price, CIF price, wholesale price and retail price, the two of them talked for a long time.

Qi Zhenjiang bluntly said that if Fang Buwei's guess was right, then the phone call between the two could convey a large amount of information.

Fang Buwei asked Qi Zhenjiang to investigate the telephone used by the other party to make the call, which was indeed the dispatching station of the Sihai Transportation Company at the Chengnan Wharf.

Fang Buwei turned out all the previous call records of the headquarters of Sihai Company, compared the two with each other, and sure enough, he found a problem.

Yesterday morning, the chief steward took the initiative to talk to this phone, looking at the time, it happened to be after the chief steward met He Qingnan, and before the banquet was held to entertain Fu Gaochang.

So is this call the chief steward reporting the situation to Li Fengnian?

Of course, it may also be about some business content.

But the anomaly is that, in addition to the phone number of the chief steward, several other phones of the headquarters of Sihai Company have been in contact with several phones near the Chengnan Wharf many times in the past few days.

Looking at the straight-line distance on the map, it is estimated that the actual distance from the dispatching station of Sihai Company is at most two or three miles.

And the time of the call corresponds exactly to several key events.

The location is so concentrated, and the time point is so close, is Li Fengnian hiding here?
