There must be something wrong with this.

Lu Xiyan was secretly annoyed, and he was secretly secretly. Why did he neglect such an important matter? The enemy could not find Ding Pengfei and the others. Couldn’t he follow the line of collecting Vibrio cholerae specimens?

You know, at the beginning, everyone encountered this accident because of this reason.

Why did he ignore such a critical factor? He even claimed to be a complete plan. Although he had been in trouble these days, he could handle it calmly without too much setbacks, and it was a bit too smooth.

At this moment, he was very anxious inside, but on the surface he had to pretend to be calm and unrestrained, so that Tang Jin could not see his strangeness.

"Have you found any clues on Lao Yuan?"

"I have found all you can find. Your student, named Ke Mo, has been sleepless these two days. There are no other clues except the shoe prints and the fabric that was pulled off from the killer, but these are all indirect evidence and nothing can be proved." Tang Jin said.

"Where is the bullet detection?"

"The US-made Colt pistol and Browning 1910 are very common on the black market. According to the analysis of ballistics and warhead wear, these are not new guns, so it is difficult to find out the origin of the guns used by these people." Tang Jin said.

"That's why there are no other clues now?"

"At present, there are no valuable clues." Tang Jin nodded, "I will give an order to let Yuan Rui and the others go back to rest, and it is useless to waste it."

"It is impossible for such a group of people to enter the French Concession to have no trace left. At least they have stepped on the Windsor Hotel in advance, otherwise how could they quickly find the suite I live in?" Lu Xiyan said.

"You mean, a guest of the hotel?" Tang Jin was unable to sit in this position today, but it was not due to relationships, but had real ability.

"Windsor Hotel has always been open to the public, and there are not many guests. Except for the third floor, there are guests on the first and second floors. Therefore, there must be their people among these guests, at least one night in the hotel." Lu Xiyan analyzed.

"I'm asking someone to check it out. We have ignored such an important clue!" Tang Jin said anxiously.

"I just thought about it. Our previous ideas were focused on the evidence on the scene. Ignoring the killer's familiarity with the layout of the hotel, and did not think about the guests." Lu Xiyan had just thought of the "bacterial species specimens" before opening up his own ideas. When the killer went straight to the private room on the third floor, it all showed that the enemy had stepped on the spot before.

There are people in the police room inside and outside the Windsor Hotel. If the killer wants to check in, there is only one way to pretend to be a resident and move in, so that he can move in easily.

It was impossible for Lu Xiyan to book the entire Windsor Hotel. It was too luxurious and too wasteful. He just booked the third floor. The rooms on the first and second floors were open normally, but the third floors were not accessible to guests and hotel service staff.

But there are more than one suite on the third floor, and there are other rooms. How did the killer confirm his location? He was lucky and happened to meet him?

"Old Lu, is there another possibility..."

"Well, you're right. If they don't send people in, then if they investigate from the outside, the location of the suite I live in, the bedroom and study opposite the Catholic Church should be across the road!" Lu Xiyan recalled the buildings and terrain near the Windsor Hotel.

"That's right, from the attic at the top of the church, you can see the situation in the suite." Tang Jin of course knew that this suite was chosen by himself, and he knew the surrounding buildings and terrain.

"This distance is more than 400 meters, which is not conducive to sniping, so if they want to kill me, they can just go directly to the hotel."

"It was because of this consideration that I chose this suite." Tang Jin said, "And as long as the curtains are pulled, the people outside can't see clearly the people inside."

"It's OK in winter, but not in summer. If you don't open the windows, it's too hot inside. I stayed in the two days, and the windows were opened every day, so it's very likely that I'm exposing myself." Lu Xiyan said.

"There are two possibilities now. One is that the killer disguised himself as a resident and came in to check in. The second is to observe the loft on the top floor of the Catholic Church opposite and discover your specific location, and then act directly." Tang Jin agreed with Lu Xiyan's analysis. In addition, he couldn't think of how the killer could use to determine the specific location of Lu Xiyan in the Windsor Hotel.

"It's still early, otherwise we'll go over and take a look?"

"Okay." Lu Xiyan nodded.

Fiat 518 on Tang Jin, called Xu Qing and Wang Lin, and a total of four people went to the Catholic Church at the corner of Foxu Road and Tongfu Road.

All four of them were dressed in casual clothes and entered the main entrance of the Catholic Church.

Today is Friday. When they came, they happened to be doing a mass. Lu Xiyan did not believe in religion. As for Tang Jin, although he is half of the British, he is actually a Chinese at heart and does not believe in the scriptures recited by foreign monks.

I heard the sound of singing chants from inside. It was estimated that the mass was about to end, and the four of them stood outside the church waiting.

After the chanting of the chants ended, the mass was over, the church door opened, believers came out from inside, and a familiar figure floated past Lu Xiyan's eyes.

Is it her?

She did not notice Lu Xiyan, and Lu Xiyan did not speak. They were here to investigate the case, and it was not good to meet acquaintances. Everyone had their own choice of faith, and he had no right to interfere.

"Four church members, the afternoon Mass Mass has ended." Lu Xiyan and the other four entered the church, and a young priest came up to meet him?"

"Father, we are not here to perform Mass. We are plainclothes policemen in the French Concession. I want to know some of the situation from you." Tang Jin asked.

"This is the public concession. Your French concession police investigated the case. How could he come to the public concession?" The young priest seemed a little unbelievable.

"We came here with permission from the Police Department of the Ministry of Works. If the priest doesn't believe it, he can call Mr. Dong Kaiziwei, deputy general manager of the Ministry of Works. "Tang Jin directly carried Kaiziwei out. Anyway, they had to cooperate, so it didn't matter if they used it first.

At this moment, Qi Huan had already met Kai Ziwei. Even if he called him, there would probably be no problem.

The young priest was frightened by Tang Jin at once. Although he was a clergyman and claimed to be a messenger of God, he was still afraid of worldly power.

Because he is not a God, he also wants to eat, drink, defecate, urinate, sleep, and have more desires and desires.

Mr. Kaiziwei, the deputy general manager of the Ministry of Industry, is of high status and power. A young priest like him is afraid that he is not qualified to say a word when he meets him. How dare he call him to ask?

Besides, it’s not just to cooperate with the investigation. As long as it does not violate the principles of clergy, what’s inconvenient?

"Father, can you take us to the loft on the top floor of the church?" said Tang Jin.

"You are going to the attic on the top floor, there is nothing there, just a flock of doves." A look of surprise appeared on the priest's face.

"Father, we just want to go to the top attic to take a look, there is no other requirement." Lu Xiyan repeated.

"Well, since you want to see, then follow me, but don't scare the doves, they are messengers of peace." The priest said solemnly.

"Father, can you ask your name?"

"Brian."

"Oh, Father Brian, I'm glad to know you."

"Thank you." Father Brian nodded lightly and led Lu Xiyan and his four men up the stairs in the church.

"Brother Tang, you should say that we are from '76'. I guess Father Brian wouldn't ask so much." Lu Xiyan left Tang Jin in a position and said in a low voice.

"That's not possible. We are all people with identities. If this is spread, it would be too embarrassing." Tang Jin denied it directly.

"Yes too."

The stairs circling up, and Lu Xiyan didn't count how many steps there were, but he kept lowering his head and carefully observing the footprints on the stairs.

The church was not disturbed by special personnel, and even if there were footprints, they had been wiped clean, so I went up the steps and had no gains.

"Two gentlemen, this is the loft of the church. Look, it is locked, and no one usually comes up except the handyman who feeds the pigeons." Father Brian explained, pointing to General Iron on the door of the loft.

"Is there anyone coming up to feed the pigeons in this loft?"

"Some, but not often, sometimes feed once every two or three days, sometimes once every four or five days." Father Brian replied.

"Are the handyman who feeds the pigeons here today?" Lu Xiyan asked.

"I really don't know this. He leaves directly after cleaning the church every day. By the way, he is still a mute." Brian said.

"Dumb?"

"Yes, all the church members here know him, his name is Mute Zhang." Brian said.

"Do you know where he lives?"

"I don't know, but there is his address in the church's repair book." Brian thought for a moment and replied.

"Father Brian, can this loft be opened with a key?"

"Yes, but the key is not in my hands. Father Fein has one, and one in the mute's hand." Father Brian nodded.

"Can you get that key from Father Fein now?"

"No, Father Fein is not here now. Although the key is not carried with him, his office is locked. I don't have a key." Father Brian spread his hands and said that he was powerless.

"Since there is no key, we can only come by ourselves." Tang Jin waved his hand and Xu Qing came forward, with a thin iron wire in his hand.

"How can you do this..." Brian became a little anxious when he saw it.

"Father Brian has the right to follow. We don't have time to wait until Father Fein comes back and get the key before opening the lock." Tang Jin explained, "Don't worry, we won't destroy the lock, it can still be used."

For those who know the principle of locks, this kind of lock can be opened easily, but it is not very complicated. Xu Qing put in with iron wire and gently fiddled it twice, and then he heard the sound of a clamping spring inside, and the lock opened.

Father Brian probably hadn't seen such a magical way of unlocking the lock, and his eyes fell all over the floor.

Xu Qing gently pushed open the door, and a smell of bird poop and feathers came towards him. Several people at the door covered their nostrils with their sleeves.

It's too smelly, it's all a pigeon's nest. It's all in this attic, eating, drinking, urinating, and sleeping. It's always impossible to clean it every day. Besides, it's not realistic.

Anyway, I just came here to feed him when I had time, and then when the door was closed, there was nothing to do.

"Inspector General, Consultant Lu, look at the footprints!" Xu Qing shouted softly, and two different footprints were clearly visible on the ground of the attic.

One deep, the other slightly shallow, the sole has almost no pattern, and the heel has been smoothed, while the one shallow can clearly see a sole pattern similar to that of the water wave, which is exactly the same as what Yuan Rui got at the Windsor Hotel.
