"Are you saying there are shoe prints on the ground outside the window?" Anna followed Gu Chen's train of thought and even poked her head out of the window.

However, after glancing around, Anna, who didn't find anything, still asked Gu Chen: "Outside the window is the lawn, and it rained heavily last night." ”

"It stands to reason that even if there were footprints, they were almost washed away, and I don't see them now. ”

"I'm just assuming, or rather excluding. Gu Chen's voice fell, and he pointed to the location of the windowsill and said, "I have checked the windowsill, and there are no traces of friction." ”

"To be precise, there are no signs of scratching from the shoes. ”

"And if someone enters the house with the door locked, the open window is undoubtedly the best way to break through, but I found no trace of footprints on the windowsill, and there is no trace of cleaning it. ”

This illustrates...... Even though Zhou Ting had the window open last night, no one entered the study from the windowsill, right?" Anna asked.

Gu Chen took a deep breath: "At present, this is the case, and there are no traces of footprints on the lawn outside the window." ”

"Actually, what if it rains heavily? ”

"Gu Chen, are you ruling out the possibility that the suspected murderer entered through the window?"

Anna seemed to understand what Gu Chen meant.

Indeed, the door to the villa is locked, and the one that can enter the room is undoubtedly the study on the first floor.

According to Nanny Dai Li's confession, when she left Zhou Ting's house, she found that Zhou Ting's study was lit with candles, and even the windows were open.

If no one enters the house, Zhou Ting's violent death may be an accident of his own.

myocardial infarction caused by a sudden cold, but because there was no one in the house to help, he died in his study.

This reasoning seems to make sense.

However, while Gu Chen and Anna were discussing, the deceased Zhou Ting's fiancé Huang Zhifeng was also brought to the scene.

At this moment, compared with the excitement just now, Huang Zhifeng seems to be a little calm now, and while looking at everyone, he no longer yells and screams.

But the body doesn't lie......

Huang Zhifeng's legs were still trembling, and his face was still pale.

"Huang Zhifeng. Gu Chen called him, and only then did Huang Zhifeng pull Huang Zhifeng back to reality from his state of mental dissociation.

"Gu ...... Officer Gu. Huang Zhifeng glanced at Gu Chen, and his attitude began to become modest.

Gu Chen came to him in two steps and asked, "Did you quarrel with Zhou Ting last night?"

"Right...... Right. Huang Zhifeng glanced at the nanny Dai Li beside him.

knew that Dai Li was a witness last night, so she didn't dare to say anything.

"What is the reason for the quarrel?" asked Anna.

"Cause...... Because, because of some trivial things in life. Huang Zhifeng slowly lowered his head, not daring to look directly into Anna's eyes.

"It's because of the debate tournament, right?"

Gu Chen was also ruthless, and directly put the problem on the bright side.

At this moment, Huang Zhifeng's face changed suddenly.

He knew that the nanny Dai Li had revealed the content of her quarrel with Zhou Ting last night to the police.

He looked at Gu Chen's eyes, his whole body trembled, and said weakly: "Since you know, why do you ask, I am your subordinate defeated, I ...... I admit it, do I ...... Aren't I allowed to lose my temper and complain?"

"I was just upset because I lost the game, so I had a big fight with Zhou Ting, but ...... However, I didn't kill Zhou Ting at all. ”

"Were you the last to leave Zhou Ting's room yesterday?" asked Gu Chen.

"Yes...... Right?" Huang Zhifeng looked at the crowd and spoke without confidence.

When Anna heard this, she was also angry and said: "Yes, yes, no, no, what do you mean by 'yes'?

"Police...... Officer, I'm ...... I'm really not sure because ...... Because after I left, I don't know who has been to Zhou Ting's room, really, I just left and didn't know anything, I don't know who else has been there. ”

Inadvertently, Huang Zhifeng's gaze swept over the crowd and soon found the nanny Dai Li.

He immediately pointed at Dai Li and said, "Oh yes, Dai Li is the last to leave Zhou Ting's house, and she is the last to leave." ”

"No...... No. was also suddenly mentioned by Huang Zhifeng, the nanny Dai Li was like a fried cat, and shrank back in fright: "Police...... Officer, I'm not the last one out there. ”

"Anyway, when I left Zhou Ting's house, you were still there, and I didn't know after that. Huang Zhifeng also insisted, which caught the nanny Dai Li off guard, and the whole person was about to cry.

Dai Li hurriedly came to Gu Chen and Anna's side and complained: "Officer, I wasn't the last to leave the house, didn't I tell you before? ”

At that time, Huang Zhifeng hurriedly walked out of the house, so I fell behind, but as for what happened in the study, I didn't know anything, I changed my shoes and left. ”

"That'...... I'm not the last one to leave. Huang Zhifeng also hurriedly defended.

The two began to blame each other, which made the study suddenly lively.

"Okay, don't make any more noise, give me peace. Anna walked between the two and told them to shut up as soon as possible.

Only then did he turn around and ask Huang Zhifeng again: "From the current point of view, last night, you should be the last to leave the study, then you tell me, what was Zhou Ting doing when you left the study yesterday? ”

"Zhou Ting, she ......" Huang Zhifeng lowered his head and pondered silently for a few seconds, and then said: "We quarreled at the time, I was in a bad mood, so I said to go back and calm down first, Zhou Ting told me to get out, she picked up the documents on the table, as if she wanted to continue working." ”

"There is no electricity, and she works by candles, this Zhou Ting is really a workaholic. Yuan Shasha listened to Huang Zhifeng's words and couldn't help muttering.

However, Gu Chen's eyes lit up, and he hurriedly observed left and right: "Yes, as a power outage, Zhou Ting lit a candle, but why didn't I see a candle here?"

"Candles?" Anna was shocked when she heard this.

For a moment, everyone looked at each other and began to look for traces of candles.

A sudden reminder that everyone began to be alert.

But at this moment, a young Italian policeman raised his hand weakly and said, "Wax...... The candle was supposed to be on the table, and I picked it up and checked it when I entered the scene, when George called me to help, so ...... So, I just put it on the table at the door. ”

"What are you talking about?" George also pointed at the young police officer on the spot and shouted angrily: "What did I tell you? Items at the scene can't be moved casually, but how can you take the items from the scene to other places? Are you crazy?"

Joe ...... George, don't get excited, I was a little distracted, and you were calling me, so I didn't realize it at the time, and I ......"

"Okay, okay, don't pursue this anymore. Anna looked at the young officer and said, "Go and get the things." ”

"Yes. Seeing that he was in trouble, the young police officer did not dare to slack off, and hurriedly ran out of the study.

It didn't take long for him to walk up to everyone with a wax table.

Gu Chen took the lead in taking the wax table from the young police officer's hand, and after observing it left and right, he asked, "Ordinary people have people who stock up on candles and wax tables at home, is there often power outages in this area?"

"Occasionally. Dai Li, the nanny on the side, said: "There have been several major failures in the lines in this area, so there were always power outages during that time. ”

"The surrounding residents were very annoyed by this and complained to the power company several times, so in order to calm the people's anger, the power company sent some candles and wax stands from door to door, saying that they would let everyone deal with it for a few days and wait for the power troubleshooting to be completed. ”

"So since then, there have been more of these things in the house, just for emergencies, but I didn't expect that there was a power outage last night, so I used them. ”

Listening to Nanny Daili's words, Anna looked up at her and said, "Zhou Ting has the old problem of myocardial infarction, right?"

"Yes. Nanny Dai Li nodded slightly.

"That is to say, it was the sudden cold that caused Zhou Ting's myocardial infarction?" Anna asked again.

"Yes, the private doctor has repeatedly reminded Zhou Ting to pay attention to this aspect, so I think it should be. Nanny Dairi said.

Anna looked at the candles on the wax table, and when the wax oil dripped down the candle and piled up in a uniform ball on the wax table, she couldn't help but say, "I think this candle should be tested to see if it contains highly toxic substances, what do you say?"

"I agree with Anna. Officer George took the lead and said, "The probability of myocardial infarction caused by a sudden cold is very low, but it happened exactly, and I think the probability of coincidence is very low." ”

"And if it is confirmed that Zhou Ting died of poisoning, then it will be a different matter, right, Officer Gu......? Officer Gu?"

George originally wanted to discuss with Gu Chen, but found that Gu Chen was no longer around, and after looking left and right in the crowd, he found that Gu Chen had long since disappeared.

"Where is Gu Chen?" Officer George looked confused.

"Just ...... I was still here. Anna was also looking left and right, feeling that Gu Chen seemed to disappear out of thin air.

Lu Weiwei was also stunned, and hurriedly asked Officer Wang and Yuan Shasha, "Which of you two saw Senior Brother Gu?"

"I didn't see it. Yuan Shasha shook her head.

Officer Wang also wondered, "But he was still here just now, why did he suddenly disappear? Where did this guy go?"

"Officer Gu!"

"Gu Chen!"

"Where are you?"

For a while, the crowd in the study kept shouting, and it seemed that Gu Chen seemed to disappear out of thin air, a little weird.

However, it didn't take long for Gu Chen to appear at the door again: "I'm here." ”

"Senior Brother Gu. Lu Weiwei trotted all the way to Gu Chen's side and asked weakly, "Where did you run just now?" ”

"I just went somewhere else to check it out. Gu Chen clasped his hands on his chest and walked to the middle of the crowd with his head down.

Yuan Shasha looked curious, and hurriedly asked, "Then Senior Brother Gu has found anything?"

Gu Chen didn't answer immediately, but looked up at everyone: "That's it, everyone come with me." ”

The words fell, and Gu Chen walked out of the door directly.

"Gu Chen, what's wrong?"

"I don't know, did he find something?"

"This guy is mysterious, I don't know what the hell he's doing?"

"Don't guess, let's go ahead and see. ”

All the police officers at the scene, after looking at each other, directly chose to follow Gu Chen's footsteps and came to the outside of the villa together.

At this moment, Gu Chen was standing next to the garden, looking at the direction of the study with his hands on his chest.

And everyone who came later also gathered around Gu Chen, followed Gu Chen's gaze, and stared at the study in unison.

"Do you see what's coming?" Gu Chen reminded the crowd around him.

There was a sudden silence.

After everyone looked at each other, they all began to join everyone to find fault.

After some thought, Lu Weiwei took the lead in saying: "On the whole, except for the traces of the house being wet by the rain, there is nothing special about it." ”

"By the way, that's what I want. Gu Chen looked at Lu Weiwei and said with a smile.

"That's it...... Is this it?" Lu Weiwei didn't understand, so she hurriedly asked again: "Senior Brother Gu, what do you want to say?"

"That's right, Gu Chen, what's wrong with this?" Anna on the side was also a little anxious.

Gu Chen was unhurried, pointed to the villa and said: "Judging from the appearance, the construction time of this villa is a bit old, and many materials are relatively old, including the walls, which are obviously made of whitewash. ”

"Yes, this villa is decades old, and if it weren't for the location, many people wouldn't have chosen to live here. ”

"But because of the existence of a house renovation and decoration company, many old villas have been renovated, Zhou Ting's villa was bought not long ago, and I heard that it was quite old, so I let people renovate the wall, and nothing else has changed much. ”

Nanny Dai Li also said the same.

Gu Chen didn't deny it, just nodded and said: "Actually, the point I'm talking about is not this, I just think that the wall paint is used to cut corners, so that the rain hitting the wall will still leave a deep imprint." ”

As soon as Gu Chen's words fell, Officer George took a few steps forward and said, "That's right, the rain still leaves a deep mark on the wall. ”

Looking back at Gu Chen, Officer George asked again, "But, what do you want to say?"

"The direction in which the rain is blowing. Gu Chen said.

"Fluttering direction?" Officer George frowned, looking at the villa again.

After a careful observation, he said, "Judging from the traces of rain, it should be in the direction of the study." ”

"You're right, Officer George, now let's come into the house with me. Gu Chen was mysterious, and left the garden directly.

Everyone was puzzled, but they didn't know what Gu Chen wanted to express, so the others followed Gu Chen's steps again and came to the living room together.

This time, Gu Chen did not go to the study, but went to the next door to the study, a room where sundries were placed.

The utility room is side by side with the study, the space is small, and there is not too much decoration, and most of the repair tools and waste items are stored inside.

Gu Chen came to the window, pointed directly to the windowsill and said, "I have checked this room, and the utility room generally does not open the window, so the heavy rain last night did not hit the window." ”

"But because this villa is a bit old, the windows are not aluminum alloy but wooden, so ......"

Gu Chen didn't say a word, he directly opened the iron bolt of the window with his gloved hands, and then gave up a position and said, "You can take a look at the color outside the window." ”

Officer George frowned, glanced at Anna beside him, and felt a little inexplicable, so he took the lead in walking to Gu Chen's side and inspecting the inside and outside of the window.

"The wooden windows are old. Officer George looked at the sides and explained, "There's nothing wrong with the inside, the wooden frame on the outside is all wet." ”

Touched the outside of the window with his hand: "Well, it's still wet." ”

"Alright, Officer George, you can go to the study next door and have another look. After Gu Chen finished speaking, he walked out of the crowd again and came to the scene of the crime just now.

At this moment, the clever police officer had already roughly guessed Gu Chen's intentions, Yuan Shasha took the lead in coming to the windowsill of the study, opened the fastener, and after folding the unilateral window back, she checked the inside and outside of the wooden window, but she was surprised.

"This ...... This is the same as the window in the next room, except that the outside is heavily soaked and the inside is dry. ”

"What? What is the inside doing?" Officer George, who hadn't figured out what Gu Chen meant before, hurriedly walked over to Yuan Shasha and checked and verified it again.

Seeing this scene, Officer George also smiled, turned back to Gu Chen and said, "Officer Gu, I know what you mean, do you want to say, in fact, this window was not opened at all last night?"

"Yes. Gu Chen nodded silently, and couldn't help but say: "The window must have never been opened, and it can be seen from the impact surface of the rain on the windowsill." ”

"If the windows had been opened last night, the inside and outside of the wooden windows would have been soaked by the rain, but what we saw was not. ”

"And I've checked the windowsill and there's no sign of getting wet. ”

Looking back at the nanny Dai Li, Gu Chen smiled indifferently: "But this is interesting, Ms. Dai Li told me that when she left Zhou Ting's house last night, she found that the window of Zhou Ting's study was open, and she was working with candles." ”

And Ms. Dai Li came to Zhou Ting's house early this morning, only to find that Zhou Ting died in the study, the point is that the window is open. ”

"Then this is very interesting, who opened the window? Or did Miss Dai Li come to Zhou Ting's study and then open the window?"

"This ......"

was suddenly asked by Gu Chen, and the nanny Dai Li's whole face turned blue, and she couldn't help but take two steps back in fright.

At this moment, all the police officers at the scene were looking at Dai Li according to Gu Chen's prompts.

"Are you lying?" said Lu Weiwei stepped forward and pointed at Daili.

"I ...... I didn't, I didn't lie, I didn't. ”

Compared with before, Dai Li was obviously a little flustered at this moment.

She looked left and right, and was also eager to justify: "You...... You make me think about it, let me think about it again, this ...... You must be mistaken, definitely. ”

"Or am I mistaken? No, you give me some time, please. ”

......
