In the banquet hall, all the guests were waiting for the results of the police investigation, and they were obviously quite sleepy and did not want to stay at the scene of the crime.

"Well, after everyone investigated, no one secretly hid the murder weapon, and no one had a lot of blood on them...... So, let's go back today, and then we need to record a statement and then notify everyone," Twilight finished the announcement and looked at the time on her watch, "It's almost 1 o'clock......"

"Smack!"

The lights in the hall suddenly went out and fell into darkness, and Twilight, who raised his wrist, looked stunned, and before he could ask, he saw the butler pushing a cake cart lit with candles coming over.

"What's going on?" Twilight was surprised, "Does anyone else have a birthday?" This is also ...... at this time"

"Alright, police department," Takagi said as he checked his watch by candlelight, "and when I give the signal, blow out the candle like the victim." ”

"Huh?" Twilight's eyes widened, "What? Takagi, you're ...... again."

"It's now, 3...... 2…… 1…… All right! ”

"Whew!"

Takagi signaled his watch, and Twilight, who was still a little dumbfounded, bent down reflexively, puffed out all the candles in one go, and the venue fell into darkness again.

"And then?"

Twilight straightened up, looked at the silent surroundings suspiciously, and was wondering when the back of the head was suddenly hit hard.

"Boom!"

"Who?!" Twilight turned her head and vaguely saw the dark shadow of a stick, and immediately said angrily, "Who hit me on the head with a stick just now?!" ”

"Hoo ——!"

As the bell rang, the floor-to-ceiling windows in the direction of the balcony snapped open, and the cold wind whistled through.

Twilight lowered her face and chased, "What the hell is going on with this arrangement?" It's useless to open the window and pretend to run outside, because I've seen the stick that hit me, and now the person holding the stick ......"

The lights turned on, and before Twilight could ask Takagi, who was sweating profusely, Conan took the initiative to stand up and say, "I'm sorry, Officer Twilight, I hit you just now." ”

"Huh?" Twilight looked down at Conan in surprise, "What stupid are you talking about, Conan, you didn't take a stick!" ”

Anyone can admit to beating people so justifiably, this kid can really laugh......

"Officer Twilight," Takata explained as he walked into the room from the balcony, "it's Conan, it's true, but the stick has now flown outside, not a stick to be exact, but an umbrella." ”

"Umbrella?"

"That's right, just like at the time of the crime, the experiment was very successful."

Gao Cheng walked towards the dazed eyes and said: "First prepare a long rope, tie a heavy object in the middle, tie a slipknot that is easy to slip open at one end of the rope, hang the slipknot on the tip of the hour hand of the big clock outside, and the tied weight hangs down over the balcony handrail, and the other end is pulled into the room through the crack in the window......

"When the lights are turned off to blow out the candles, tie the rope that has been pulled in to the handle of the umbrella, and hit the officer with the umbrella the moment the candle is blown out, and then the umbrella will be pulled out due to the fall of the heavy object, which is roughly the case."

"But will it work? I didn't see it just now, but someone at the birthday party will definitely find the rope on the balcony. Twilight touched her head in frustration.

Even then, you don't need to hit him on the head, do you?

"Of course, in fact, the prisoner should have used something like fishing line that is relatively difficult to find," Gao Cheng's gaze swept over the bearded people, "The big clock outside is just above the balcony, and there is a loop-shaped notch in the hour hand, and when you go straight down to 6 o'clock, the rope tied to it will soon fall off......

"As for the reason why the murder weapon and the heavy object can't be found, it should have fallen directly into the well below, and it is easy to do as long as the rope is extended."

"So," Twilight asked, "what about the blood?" The prisoner stabbed the victim in the chest, so he couldn't have turned to the victim's back immediately after being stabbed to control the victim, and used the force of the heavy object to pull out the murder weapon, right? If it was only a stab in the victim's chest, because there was a necklace coated with fluorescent paint on the chest, it would be reasonable, but it was impossible to move flexibly in the dark, and ......"

"No, it is impossible for the murderer to use heavy objects to pull out the murder weapon, and it is easy to be found if he carries too large heavy objects, so the prisoner pulled out the murder weapon with his own hands, and the reason why he did not splash blood all over his body is because of ......"

Gao Cheng's gaze fell on the beard and the light side of Dingwu.

"Before revealing the reason, we can first find out who the killer really is."

"Can you know it directly?" Twilight was stunned.

"Yes, the key is bloodstains," Gao Cheng explained, "There are only a few Mr. Light Side who are stained with blood, namely Mr. Light Side, who was close to the hands and cuffs of the fallen victim after the incident, Miss Zhou Fang, who rubbed blood on her arm, and Uncle Guyuan, who was splashed with blood on her shoulder......

"The old man stood next to his wife, and it was not strange that he was splashed with blood, and the blood stains on Miss Zhou Fang's arm were probably wiped by the murder weapon when it flew to the balcony...... Well, I would like to ask Mr. Lightside how to get close to Madame in order to leave such a bloodstain. ”

Gao Cheng quietly looked at the lightly trembling hands.

"Hands and cuffs, are you pressing directly on Madame's bleeding chest? Even so, how can your clothes and pants not get a little blood, and it's strange that you didn't step on blood with such a large amount of blood......

"So there is only one reason, the reason why you got blood on your hands is because you took the murder weapon directly!"

"What?" Twilight was shocked, "Mr. Lightside is the murderer?!" The murder weapon is ......"

"Didn't I just say that? It's an umbrella, but he uses a folding umbrella, which can be hidden in his arms to make it easier to commit crimes without being discovered. ”

Gao Cheng made the final reasoning.

"I can guess a little bit from their testimonies, big guys, fat guys, fast speeds, rubbing of fabrics...... In fact, they are all murder weapons, so big that they helped Mr. Butler block the splashed blood, because the umbrella was opened, and the prisoner also relied on this method to avoid the blood stains......

"I think it should be a sharp murder weapon installed on the tip of the umbrella, and then the umbrella was held to assassinate the lady, when it was pulled out, all the blood was blocked by the umbrella, and the reason why Mr. Light Side got blood on his hands was because he was in a hurry to put the umbrella away, and in order to save time, he probably used a rubber band or something like a rubber band tied to his wrist."

Gao Cheng walked past the trembling beard: "To be able to do this, you must be very familiar with this place, as the designer of this villa, you don't even need to test to know how long the rope is, and I heard that you also asked your wife to borrow a pocket watch during the party, and it is easy to set aside a few seconds to create time for yourself to commit crimes."

"I took the initiative to help cooperate with the investigation, but the real reason was probably that it was raining outside again, so it would be very difficult to leave, right? Can you tell me, where is your umbrella? ”
