"Wu Gan, you are now a member of the investigation team, look at the surveillance. ”

"I'll see. ”

"That'...... Let's take a look at the monitoring first. ”

"Why should I look at the surveillance first?"

"Obviously, look at the surveillance first, so that the murderer is likely to be found, although I don't know very well, but at least there must be surveillance in the guest room corridor on the top floor. ”

"I guess there will be, but why was the murderer discovered?"

"Then why do you ask that cleaner?"

"I wanted to ask her how she got the door open. ”

"It's boring to ask this question, it's not like you haven't stayed in a guest room!"

Lin Bing, this temper is a little weird, she is very advocative, she should watch the monitoring first, but Wu Gan...

Why did she do that?

Anyway, Wu Qian has his own reasons.

"You see, I was just talking so loudly about entering the scene, and I was observing, and I just wanted to see who had a change in their expression about this matter. ”

Wu Qian explained his previous approach at the scene of the crime.

But...

"What's the result?" Lin Bing was looking forward to it.

"Like, it's not a big deal, a lot of people have changed. Wu Gan's answer was quite speechless.

"......" Lin Bing rolled his eyes.

Smith over there didn't care so much, the three of them came all the way and took the cleaner to a small room, ready to be questioned.

"I said, I said, actually...... Me, I...... It's no different, I was working, I came to that room, I knocked on the door, and found that there was no sound inside, and there was no Do Not Disturb sign outside the room, so I did what I had to do, which was to clean it, using our master card. ”

This chubby cleaner is called Maria, and the woman with this name in the Philippines can be said to be ...... Anti-war, what Maria did was the absolute standard process.

So......

Wu Qian actually has a key question that must be asked, "In other words, the lock of the door has not been broken?"

"No, it's normal. Maria emphasized once.

When Smith heard this, he immediately said, "This should mean that the murderer did not enter through the main entrance." ”

When Lin Bing heard this, he understood, it turned out that Wu Qian wanted to verify this matter.

Judging from the current situation, it is already known that the lady's name is Cai Mingzhu, and she and James died in their own room, so how the murderer enters the room is definitely a key.

The guest rooms are all electronic locks, that is, the room card is now used, so a brush, it will be done, and the room service department of course has a total card, the cleaner usually uses, clean it, there is no problem.

In fact, this Mary also had her own companions to witness to each other, so that she could show the tenant that she was not stealing.

Sometimes it's clean, that's it.

Now, here's the problem.

The scene of the crime is Cai Mingzhu's room, and there is more James in her room, which is no problem, but the door lock was not broken, and the murderer entered the room, what method did he use?

"There are windows, right?" Wu Qian asked briefly.

Smith smiled strangely, "Of course, but, Mr. Detective, we're on a cruise ship, this window, haha......"

In fact, Wu Qian was not unaware of this.

The Asian Jewel, this is a new ship, the design is quite avant-garde, this new design, in terms of the cabin windows, is a little different from the previous ones. That is, the outer layer of the hull is relatively smooth, as if it is a warship now, in order to avoid radar, so on the side of the ship, it is integrated.

In the past, cruise ships would have had some corridors, but this ship did not, which has the advantage of increasing the interior space, that is, adding many rooms.

Moreover, Cai Mingzhu's room itself is on the edge, you know, not all rooms on the cruise ship have windows, for example, some rooms are in the 'internal test'.

In addition, with the design of this cruise ship, the windows can't actually be opened, and if they do, there's no risk of falling into the sea.

Even if it's a suicide, the news of the dead man is not good.

So, for now, the murderer entered the room through the window, which is also impossible.

"Unless that person is Spider-Man. Lin Bing also figured it out.

So, well, how did the murderer get in?

In this way, it seems that the only thing to do is to watch the surveillance.

In Wu Gan's helplessness, Mr. Smith took them to the security monitoring room.

Soon, the surveillance video of the corridor on the fourth floor of the guest room on the fourth floor was called up last night.

Thereupon...

"......" Lin Bing gave Wu Gan a roll of his eyes.

Really!

Wu Qian was photographed.

That's right, he and Li Xiumin were two people last night, and they ...... yesterday It's sure to be photographed, but it's strange that it can't be photographed.

In other words, Wu Gan, this guy, didn't want to watch the monitoring so much before, he also had his own purpose.

It's a little embarrassing.

Smith smiled as well.

Wu Gan, this guy, gnawed on it before he went in.

Ahem......

Let's put it down, hurry up.

Soon, some problems were identified.

"Is Ms. Cai having a party?"

"yes, why are there so many people?"

"This... ”

During the surveillance, several people entered Cai Mingzhu's room, of course, they also saw Cai Mingzhu and James returning to their rooms before, so what are these individuals doing?

But fortunately, half an hour later, these people all went out, and Cai Mingzhu sent them out.

Not long after, I saw the food delivery coming.

Naturally, I also saw Cai Mingzhu open the door, and then ...... The waiter who delivered the food also came out.

There was no problem with the whole thing, and after that, there was nothing.

What does this surveillance video say?

"The deaths of two people occurred after the dining car. Lin Bing naturally came to this conclusion.

Smith thought for a moment, "Who's that murderer?"

This question is also natural.

By the way, who is the murderer?

"I counted the people who had entered before, and it was seven. "Lin Bing is quite smart.

"But they all came out. Smith said.

"That...... Dining car?" Lin Bing asked again.

"You mean, there's someone hiding in the dining car?" Smith thought it was a possibility...... Probably that's all there is.

At this time, both of them set their eyes on Wu Gan, not only them, but even the security guards in the security monitoring room also looked at Wu Gan.

You're a detective, tell me about it.

Wu Qian hasn't said a word since he came out of surveillance, what the hell is he thinking?

"I didn't expect to encounter such a difficult case. ”

Is this saying, is it difficult?

Others don't know, but Lin Bing understands that Wu Qian will not easily say such a thing.

But......

"There is still a direction for the investigation, those seven people, look for it, let's talk. ”
