After investigating the basic situation of the shipwreck accident 13 years ago, it was already late at night, and everyone was called downstairs to inquire alone.

At that time, the fat housekeeper did not participate in the sea trip because of seasickness, and the housekeeper Shigeko Xianzaki and daughter Bohua stayed at home because of a cold, and then lost the history of Mian Yingsheng of his father and younger brother......

While asking forensic personnel to collect fingerprints, Gao Cheng considered the connection between the shipwreck accident 13 years ago and the homicide.

Four people were killed, and most of the family members continued to work at the home of the country's friends, and Yokozo believed that it was a great possibility that the prisoners would retaliate and kill.

Someone who died in that accident probably thought that Mr. Sekiguchi was the cause of the accident and killed Sekiguchi......

In the current situation, it seems that there is no problem with Henggou's judgment, and the prisoner seems to be among the relatives of several victims, and the targets of revenge are the people who were saved that year and the Guoyou couple.

"I'm sorry, Detective Chengto," after Gao Cheng finished collecting his fingerprints, Henggou smiled apologetically, "In order to distinguish them from the prisoner's fingerprints, I can only trouble you." ”

"It's nothing," Gao Cheng looked at Xiao Ai, who was bowing his head next to him, and then asked, "Children don't need it, right?" ”

"Uh......"

Yokogou inadvertently thought of Conan, who likes to run around the scene, and wiped his sweat with a dry smile.

"There shouldn't be ......"

"By the way, Officer Yokogou, is the alibi the investigation complete?" Gao Cheng asked suddenly.

"Except for the driver, Mr. Mianyin and Mr. and Mrs. Guoyou, no one else has a clear alibi, and we temporarily took the fingerprints of everyone except Mr. Guoyou......"

Henggou scratched at the coral's hair.

"However, only Mr. Sekiguchi's fingerprints were detected on the rope, and the murderer may have brought gloves or something."

Gao Cheng immediately thought of Mianyin, who wore gloves most of the time, shook his head and continued to ask, "What about Mr. Guoyou?" The couple is likely to be the next target of the killer. ”

"He doesn't seem to trust us much," Yokozo said embarrassedly, "He said that no one was seen until the day of the Buddha's destruction, and he was hiding on the third floor alone......

"What about the others?"

"Let them go back to their rooms for the time being, Mrs. Kunyou's words......"

The group walked upstairs, and Mrs. Guoyou was still shouting loudly at the entrance of the third floor, pressing the fingerprint reader, looking quite annoyed.

"Husband! Open the door! What are you doing with this wife of mine too? ”

"Don't be in such a hurry," said the loud voice of Guoyouchun over the intercom, "After finding out something, the two of us will discuss it again, okay, let's talk about it later......"

"Husband?"

"What? How, how is that possible? You...... Ah——!h Kunyu Junda's voice suddenly changed in pain.

"What's wrong?"

Gao Cheng followed the Henggou police officer and ran upstairs, only to hear the loud screams and the sound of Guoyou Chunda screaming and falling to the ground on the intercom, no matter how anxiously Mrs. Guoyou shouted, there was no response.

"What's going on?" Henggou said urgently, "Mr. Kunyou?!" ”

"This walkie-talkie is connected to my aunt's bedroom, right?"

Conan asked, and ran quickly downstairs to the room below.

On the 3rd floor, there is only a balcony to escape from the electronic door, and Gao Chengma knew Conan's plan, but he didn't follow immediately.

"Officer Henggou, can you check if anyone in the Guoyou family is not in your room?"

"Huh?" Henggou swallowed, "Could it be that the prisoner is on the third floor now?" But Mr. Kuniyou said that no one would be seen......"

"Also, immediately keep an eye on all the balconies on the 3rd floor, Officer Henggou."

Gao Cheng has rarely seen such a rampant murderer, and after reminding Henggou, he also followed Conan to the balcony, no matter who is on the 3rd floor, as long as he keeps an eye on the exit, he will definitely not be able to escape.

It can be said that the choice of the prisoner has led him to death......

"Intruders found! Discover the intruders!! ”

Gao Chengcai followed Conan to the outside of the guest room on the second floor, and suddenly a rush alarm sounded in the whole villa, and the piercing sound made the night extremely noisy.

Conan ignored the alarm and noticed a long rope hanging from the balcony above, as if someone had tied the rope he had used to hang the pass to the railing again.

Conan was surprised, and hurriedly grabbed the rope and slowly climbed up to the 3rd floor, seeing that Gao Cheng's vest was sweating.

This guy still likes to mess around so much......

"Castle ...... Brother Joto," Conan's voice quickly came from above, "It seems like it's too late......"

"Don't mess around yet."

Gao Cheng frowned, and saw that there were already police officers monitoring the balcony on the third floor below, and hurriedly exited the room.

The alarm soon stopped, and when Gao Cheng returned to the entrance on the third floor, the electronic door was still closed, but the Henggou police officers were nowhere to be seen, and only one police officer was guarding the door.

"Where's the Henggou officer?" Gao Cheng asked.

"The officer and the others are inside," the officer said as he saw Gao Cheng stand up straight, "and when we heard the alarm, the door ......suddenly opened on its own."

"Opened it yourself?" Gao Cheng's figure paused, "Is anyone coming out?" ”

"Not ...... yet"

"Brother Joto," Conan's voice came over the intercom, "are you at the door?" ”

"What's going on inside?"

"Everybody's in, I'll open the door for you now."

The situation on the 3rd floor suddenly became a little complicated, leaving the police officers to continue to guard the entrance, and Gao Cheng, Xiaolan and later Xiao Ai entered together.

Strangely, it wasn't Conan who opened the door to let everyone go to the 3rd floor before, it seems that the door was opened by the prisoner when Conan was climbing the rope, and the alarm should have been triggered by the prisoner.

Gao Cheng recalled the situation at that time, and the prisoner obviously knew the situation outside through the walkie-talkie, and there was only one possibility to actively trigger the alarm, which was to muddy the water.

Looking at the Henggou police officer who began to inspect the scene of the murder and the bedroom of the Guoyou couple, Gao Cheng turned his gaze to Conan.

"Officer Henggou," Conan's immature childish voice said, "can you look in the other rooms on the third floor?" Because when the alarm sounded, I went downstairs to the room, and when the prisoner might want to escape, he saw me climbing up the rope and ran to the other room......"

"Indeed," Yokogou said, "since the electronic door was opened by the prisoner and he failed to escape from the balcony in time, it is very likely that he will remain on the third floor!" ”

"Let's help find that prisoner, officer!"

"It's too dangerous, you people can't run around anymore......"

Henggou had a headache and looked at the people of the country's friends who looked frightened and resented the murderer.

I wanted to make sure I hadn't left my room without permission, but all of them came to the third floor without permission.

"Anyway, let's look in every room, and everyone follows me."

Gao Cheng silently watched as everyone left with Henggou, turned around and looked at the surrounding scene.

The floor-to-ceiling window was open, and Kunyou, Chunda, fell on the side of the bed, grabbing the balcony outside the floor-to-ceiling window with one hand, and you could see that there were still medicine bottles and broken pills on the balcony, and the other was the rope that Conan climbed up on the railing.

At least it can be established that the murderer is still on the third floor......

Gao Cheng squatted down to check the condition of Guoyou Chunda, his eyes widened with horror, and saliva flowed from his mouth.

Acute heart attack, definitely hopeless.

The murderer specially frightened Kunyou, and took away the medicine bottle when Kunyou's heart attack, which is a common torture type of murder in revenge incidents, including previous intimidation......

There are some vague clues, but there are still some doubts.

Is there more than one prisoner?

There's also an invisible prisoner......
