This is actually a very clumsy lie, Brother Hao didn't pay attention to listen at the time, but put most of his mind on that convenient corridor, so he didn't react for a while, but this time he suddenly realized that the criminal was that person, there was no suspense. =music=wen=

But just as Brother Hao was about to open his mouth to expose the criminal, a young man suddenly rushed in outside the monitoring room, looking dressed as a sailor, he stumbled in, his face was miserable, and he seemed to be frightened.

As soon as he opened his mouth, Brother Hao had a crisp sound in his mind.

Ding dong!

Naoto Yamazaki? Brother Hao was stunned, this seemed to be ......

"Father!" Yamazaki on the side suddenly screamed when he heard this, and then grabbed the sailor and stumbled out, Brother Hao hurriedly followed, Asami and Akemi also turned pale, didn't say anything, and trotted towards the place of the incident with everyone.

Soon, everyone rushed to the room where Naoto Yamazaki was killed.

Different from the guest room they live in, as the owner of the cruise ship, Naoto Yamazaki, the room he lives in is a little special, in short, it is an independent room, there is a round window on the door, the size of a palm, Brother Hao knows this thing, it is also a style, and according to the words of the sailor who came to report the letter, he originally wanted to ask his boss what type of drink he wanted to drink at night, but he knocked on the door for a long time and no one answered, so he stood on tiptoe and looked inside from the round window, and found that it was ......

"Father!" Yamazaki stood outside the door and knocked frantically on the door, seeing that his father really didn't react, he tiptoed, and finally there was a howl of horror, Brother Hao also took a look, and found that there was a person in the room who was lying on the ground, and the blood stains around him were clearly visible.

"Why can't the door open?! Bastard! What about the keys? Who has the key?! Pulling the door, Yamazaki found that the door had been locked by his father from the inside, and immediately became furious, and roared at the young sailor on the side, "Why don't you go to the security room and get the spare key!" ”

Watching the figure of the young sailor disappear at the end of the corridor, Yamazaki's body went limp, and he sat down on the ground in a dejected manner, covering his face with his hands, and began to sobs uncontrollably.

Asami and Akemi also had a sour nose, and stepped forward to comfort the big boy, only Brother Hao didn't feel anything, he blinked his eyes, and looked in through the round window.

It can be seen that the room where Naoto Yamazaki is staying is not large, and it looks like it is about thirty square meters, but it is just ...... But it's a steel chase with an unobstructed view, uh...... If nothing else, the case at this level is estimated to be a little tricky.

"The key to this room...... Who has it? ”

Brother Hao thought for a moment, and then asked Hitomi Yamazaki, who was sitting on the ground crying with pear blossoms, Yamazaki wiped his nose and sobbed back to Brother Hao's words.

"This is my father's favorite room, and there are only two keys, one on his body, and the other one is hanging in the security room all the time."

"Where will the two keys be when the cruise ship docks at the harbor and does not sail?"

"If my father is not on the cruise ship, no matter whether the cruise ship is sailing or not, the two keys will be put away by my father and kept by themselves."

That is to say...... Almost no one but your father can touch these two keys, right? ”

"Yes."

That's right......

As he was talking, the sailor brother who had just stumbled to get the key also returned, in fact, to be honest, Brother Hao really hoped that he couldn't find a spare key in the security room, so that the case on this level would be a little easier......

"Young master, young master, key, key!" The person who came took three steps and two steps, jumped directly in front of Yamazaki and handed the key to Yamazaki.

No way.

Brother Hao's eyes closed, and it was over.

In a panic, Yamazaki opened the door, and this action also pushed Brother Hao into the abyss of egg pain, and there were more than three security personnel staying in the security room all the time, responsible for monitoring and scheduling, that is to say, the spare key was hung under everyone's noses almost all day, and it was completely impossible for someone to steal it...... Then this time the case is much "simpler".

- This is a case of murder in a closed room.

Oh!

Don't say it, it's true, after entering the room, Brother Hao was pleasantly surprised to find that except for the door with a small round window behind him, there is really no other entrance and exit in this place, the only window? Outside is the sea, and the windows are completely sealed, let alone people, ghosts can't enter.

And after carefully observing Naoto Yamazaki's corpse, Brother Hao realized something even more desperate - this old man with hair didn't even leave a death message before he was temporary, damn it, how is this going to play?

Although the egg is a little painful, but no matter what, the reasoning still has to continue, only twenty minutes, the first thing to be solved, is the mystery of the secret room, only by solving this, it is possible to find the murderer along the vine...... But how does this work in just twenty minutes?

Brother Hao's eyes were like torches, he glanced around the room, and finally stopped at the only entrance and exit - that is, the door, it is impossible for the murderer to go out through the window, the only way is the door, the secret of the secret room...... It must be above this door.

Murderer...... How?

Brother Hao returned to the door of the room, took a closer look, and found that in addition to the main lock, the inside of the door of the old Yamazaki was also equipped with an auxiliary lock, ah, it was the kind of thing with a bolt.

Due to the existence of the auxiliary lock, it becomes extremely difficult to pry the door in, and if you open the door by any violent means other than using the key of the main lock, it will cause irreparable damage to the auxiliary lock, so this time the old Yamazaki was killed...... There are two difficulties.

First, assuming that the murderer did not have a key, how did he enter the room without breaking the auxiliary lock; Second, how did the murderer restore the door, especially the auxiliary lock, without using the key after killing Lao Yamazaki, to form a secret room.

"This ...... If the murderer is someone Shibo knows, then there is no such thing as picking the lock? Is it possible to directly deceive Shibo's door and kill Shibo? ”

After listening to Brother Hao's simple analysis, Asami on the side said in a trembling voice, in her opinion, if you want to avoid the basically unsolvable auxiliary lock, then this method is undoubtedly the best. Mobile phone users should browse and read for a better reading experience.
