In the Metropolitan Police Department conference room, Gao Cheng yawned boredly in his seat.

He seemed to be thinking too much, in this kind of place, he couldn't even interject at all, or very few people would communicate with him, and he was a little special in the whole conference room.

Except for being very polite when greeting him, the advisors didn't seem to be very interested in him at other times, but fortunately, they came over after a while, but their faces were extremely solemn.

"What's wrong?"

"Brother Chenghu," Twilight said in a deep voice, "Something happened again, just now Xiaolan called the police, saying that when she was at a birthday party with Maori, the owner was killed, and it was quite tricky, it seems to be a ghost murder incident......"

"Another ghost killing?"

Gao Cheng hurried out of the conference room with Twilight under the eyes of the advisors.

I don't know when it started, as long as there are any cases involving ghosts and the like, everyone likes to associate him, because he also has the nickname of "ghost detective".

It turns out that all ghosts are fake, and presumably someone committed the murder this time.

But if Uncle and Xiaolan are here, Conan shouldn't be absent, right?

Baokejia villa, the scene of the banquet hall on the second floor.

"I see, after the candles of the birthday cake were blown out and the room went dark, the owner of this mansion, Ms. Baoke, was stabbed in the chest with someone's murder weapon."

After the forensic personnel finished collecting evidence, Twilight squatted next to the body of the hostess who had fallen next to the cake cart, and could see a large pool of blood flowing from his chest, and his body was also covered with splattered bloodstains, with a blank space in the middle, as if the blood stains had been blocked.

After a pause, Twilight looked at the balcony behind her with the floor-to-ceiling windows open.

"A few seconds before the lights came on again, the killer escaped from the inner courtyard through the balcony over there with the murder weapon......"

"The key is the blood stains that splashed on the ground in front of the lady, and the blood stains were interrupted in front, this is the evidence that someone was standing here when he pulled out the murder weapon, and he was splashed with blood, but among the guests at the scene, although some people were splashed with a little blood droplets, none of them were covered in blood......"

Kogoro Mori looked around the scene and deduced.

"And there were blood stains on the window frames and the railing of the balcony, so the prisoner who was splattered with blood must have escaped through that window......"

"But, Brother Maori," said Twilight, speechlessly, "you said it yourself, it was raining until the evening, and the ground was soaked, and if you jumped off this second-floor balcony and escaped, the prisoner would have left footprints, right?" But look down, there's nothing in the yard. ”

"That's ...... too"

"It's starting to rain again, and the weather forecast says it will stop in the evening."

Gao Cheng put his hands in his pockets, stood on the balcony and watched silently for a while before returning to the hall.

The situation at the party can be roughly restored, but the question is how the killer disappeared, as well as the murder weapon......

Another thing I care about is the threatening letters that have been sent for several years.

Nothing happened in the past few years, but this time I found my uncle to come over as a bodyguard and there was a murder.

Then there was the accident that happened here 4 years ago, the deceased was a watchmaker, and it happened to be the day of the birthday party.

"Hmph," the bald old man looked at the corpse of the Baokov on crutches, "Of course, ghosts can kill, and that watchmaker didn't die of an accident at all, but was killed!" By this cold-blooded woman who thinks she can control time and thinks she is a god! "Huh?" Twilight returns to the room and asks, "What the hell is going on?" ”

The old man glanced at Twilight and said in a deep voice: "It was a very stormy weather, and the clockmaker brought a safety rope to repair the dial of the big clock outside, but it was blown off by a gust of wind and fell into the well in the courtyard below the big clock......

"It sounds like an accident caused by negligence, but if this woman hadn't started her birthday party in the right minute, and went to find someone right away, maybe it would have been fine."

"Did you notice someone missing when the party started?" Twilight was surprised.

"Yes," replied a bearded man with a pipe, "and the watchmaker was drowned in the well during the party, and by the time his body was found it was breakfast the next day, if the party had been postponed and had been found immediately......"

"Everyone was so busy after the party started that they didn't have time to find anyone."

"Look, it sees, the one who hates the victim the most is the clockmaker who died."

The people of Twilight were a little furious when they heard this, and they all looked at Gao Cheng, who looked thoughtful.

Gao Cheng was not affected by the words of the old man and his party, but only wrote down the more objective parts of the speech, and spent the rest of his time looking for clues on the scene.

This kind of crime committed in public, again in the dark, it is impossible not to leave traces, in addition to the bloodstains, it is worth considering the method of the prisoner stabbing the hostess in the chest in the dark.

Moreover, it is obvious in this case that the murderer is the guest who attended the birthday party at the scene, just pretending to escape, and hiding in the crowd from beginning to end.

Although voices were heard in the darkness, no one had ever seen the prisoner escape from the balcony, only the floor-to-ceiling windows were opened.

The only thing that is in doubt is the murderer's handling of the murder weapon, and why there is no blood splashed on his body......

"It's fluorescent paint," Gao Cheng said as he looked at the victim's corpse and covered the light above the necklace with his hand, "The necklace on the victim's neck was coated with fluorescent paint, and it glows when the light is low, and that's probably how the prisoner found his location...... Has anyone ever touched this necklace? ”

"Huh?" The butler replied, "Very, a lot of people, everyone seems to have touched it at the party, because this birthday party is also a display of this piece of jewelry that Madame has newly bought......"

"That's right," Mori Kogoro said in a deep voice, "and she proudly took out that gold pocket watch and touched it for me, so wouldn't everyone be suspicious?" ”

"Of course......"

Gao Cheng said to all the guests who were talking: "The prisoner is among these people at the scene. ”

The bald old man frowned when he looked at Gao Cheng, and the other people's faces were not very good.

"Isn't there still blood on the balcony? And I did feel someone rushing to the balcony......"

"It's just that it looks like someone has escaped through the balcony, and it feels like it's going to be deceiving," Gao Cheng stood up and turned to Twilight, "Police, let's interrogate the guests first, and search their belongings by the way." ”

Twilight nodded cautiously and said, "It can only be like this first, what pierced the victim's heart was a long sharp murder weapon similar to an ice pick, if the prisoner did not escape, it is very likely to hide it on his body......"

"Wait a minute," interrupted the bald man, "what about the bloodstain?" According to you, shouldn't the prisoner be splattered with blood? ”

"Yes," the female guest next to him followed, "we are not going to be questioned and searched without solving this problem first!" ”

"There's nothing to suspect, it's rude to investigate like this, isn't it?"

The guests were all in an uproar, all of them with heads and faces, quite repulsed by the police investigation, and asked to go home one after another.

Gao Cheng watched all this quietly.

With so many guests coming to the birthday party, no one seemed to be sad about the death of the Paulkov, and this lady was really a failure.

No wonder they invited the murderer to the party......

Who is the murderer?

Gao Cheng's gaze swept over the guests who were in a hurry to leave, and before he could stop them, the bearded pipe man next to him stopped everyone.

"Wait a minute, everyone!" The pipe man persuaded, "Don't you understand? Now that a person has been killed, everyone is here today to celebrate her birthday, and if the prisoner is still among us, isn't it what we should do to assist the police in their investigation? ”

Although there were some twists and turns in the process, in the end, the guests stayed, maybe for the sake of face, maybe really for the sake of the Paulkovs.

"Joto, what do you think?" Conan asked, looking at the pipe men who were first taken outside for questioning.

"These people were with the victim at the time of the crime, right?"

Gao Cheng followed out of the banquet hall.

The most suspicious thing was that the 4 people who were with the Baokov people at that time, the butler, the pipe man, the old man and a female guest, listening to Conan, in addition to the butler, the other 3 people also came to the Baokov house early, and the Baokov people were much more familiar than the other guests.

"Let's hear their testimonies first."

Regardless of the reason, no matter how unpleasant the victim Baokov is, murder is a serious matter, and the only thing you can do as a detective is to give the deceased a truth.

It is impossible to make a watchmaker who died four years ago a murderer......
