Although there is no evidence to confirm the confession of writer Wu, it must be admitted that his words lead the case to another possibility.

"To be honest, I don't believe Wu Xing's words. His motive for murder is very clear." Officer Liang said, "He is very cunning and may fabricate testimony in his favor."

Jian Jing nodded: "The painter has already talked to Mr. Kang about publishing a collection of essays. He must solve this problem as soon as possible. But his testimony can explain the problem of the door lock and footprints."

The footprints left on the balcony are toes facing outward, from the direction of the bedroom, and there are no inwards. In other words, the person flipped from the bedroom to the studio and left, rather than from the studio to the bedroom.

Considering Writer Wu's age and clumsy figure, it was unlikely that he could quietly break into Painter Chang's bedroom and kill her.

And the probability that Painter Chang would open the door to this old pervert in the middle of the night was even lower.

"He must have lied somewhere. A normal person would leave immediately if they were scared." Jian Jing said, "The locked door pretends to be a secret room to delay the painter's discovery, so that he can leave and destroy the manuscript."

Officer Liang agreed, "That's right."

"But we still have to open the safe." Jian Jing worried, "After all, if the safe is not opened, I can't think of how Writer Wu got the manuscript out."

Officer Liang hesitated for a moment and agreed, "Can you open the lock?"

Jian Jing sighed, "Let's take a guess. Painter Chang wouldn't set a complicated password. Just try birthdays and anniversaries."

They searched for Painter Chang's personal information online and tried one by one.

None of them worked.

"It's too much of a gamble to try the password." Officer Liang felt that this attempt was unreliable, and decisively changed his mind, "Assuming the murderer knows the password, he must be someone very close to the painter. Yes, Xiaotian, she is the only one who came to the painter in the middle of the night and was let into the room."

Jian Jing hummed, her mind a little confused.

Indeed, Xiaotian was scolded by the painter today, and she was full of complaints, so she had the motive to kill. It was not difficult for her to find an excuse to enter the teacher's bedroom in the middle of the night. The painter would not be particularly wary of his female students.

"Remember? She was responsible for making medicine for the painter." Officer Liang immediately thought of a key point and connected it all together. "As long as you add a little sleeping pill to the medicine - didn't Eddie say she had it - the painter will lose consciousness without any defense."

It was well-reasoned and convincing.

The problem was, "We have to find evidence."

Officer Liang immediately said, "I'll check the medicine. Together?"

Jian Jing thought for a while, still unwilling to give up the safe: "I'll study this again."

"Then let's do it separately." Officer Liang rushed downstairs to verify the guess.

Jian Jing continued to study the safe and found that the unlocking finger was very special. It was a heart, which seemed to be special. She showed a subtle look, took the painter's mobile phone, and unlocked the screen with her birthday.

After a moment, she tried to turn the dial, 9-3-4-1-5-2-0.

YG520.

With a "click", it opened.

Jian Jing: "Tsk." It's the nine-square grid again, so easy to guess.

She squatted down to get something out of the safe, but her hair was not tied up tightly, and a strand of it slipped from her shoulders, and the end of her hair touched the ground. Jian

Jing quickly reached out to pick it up, but this time, she was stunned.

No way?

No way?

Oh my God!

"You opened it? What did you find?" When Officer Liang came back, he saw her sitting in front of the safe with an unbelievable look.

Jian Jing turned her head, took a deep breath, and her face was still shocked: "Look."

She lifted the bed sheet with a big swing.

Officer Liang turned on the high-intensity flashlight and saw an extremely clean area under the bed, which was obviously different from the dusty area around it.

It was not difficult to guess that someone had been hiding under the bed not long ago.

Officer Liang suddenly had an idea and blurted out, "Did he sneak a peek at the safe password while hiding under the bed?"

"That must be the case." Jian Jing rubbed her arms and got goosebumps.

She said, "I think some of the testimony of writer Wu can be proven to be true. The murderer had been hiding under the bed of painter Chang and left after killing the painter, so the door and safe were open."

"When did he hide here?" Officer Liang said, "I just checked the Chinese medicine package, and yesterday's portion is still there. It has nothing to do with the medicine."

Painter Chang's medicine was packaged separately by day, and the date was written on each bag. The total number of pieces was clear and there was no missing. Xiaotian did not lie.

Jian Jing picked up the red wine glass on the bedside table and shook the remaining wine. She had taken a quick look before and didn't find any drug powder or particles. She was not sure, "Could it be this?"

"We'll know after a test." Officer Liang took out his phone and looked at it. He was very depressed. "The scout said that no one would be there until after 12 o'clock."

Jian Jing had no choice but to temporarily stop the drugging process and take out the things in the safe: "The murderer opened the safe, which proves that there is something he needs."

"What are these?" Officer Liang frowned as he flipped through the safe.

The things locked in the safe by Chang Huajia were not jewelry or passbooks, but some relics of Yang Guan: his diary, photos with relatives and friends, some letters and other documents with a sense of age.

Jian Jing's heart moved slightly.

These things have no monetary value, but are closely related to Yang Guan. I thought the motive was from Chang Huajia himself, but now it seems that this is not the case.

"The things are very fragmented, how do you know what was taken away?" Officer Liang asked.

Jian Jing said, "Look through them all first."

Officer Liang's face showed a struggle, but he said nothing and picked up a book of documents painfully.

Jian Jing took the initiative to pick up the letters and read them one by one.

These private letters that have not been made public contain more information, revealing many industry gossips from more than ten or twenty years ago, and writer Wu was also mentioned. But except for him, the others have nothing to do with the people present.

"There are letters here." Officer Liang searched the notebook and found a few pieces of letter paper in the interlayer of the cover.

It was hidden so secretly that both of them became interested and immediately unfolded it to check.

As expected, the content of the letter was somewhat sensitive.

It was from Yang Guan's ex-wife, who said that she was ill and unable to take care of their daughter, and wanted him to take care of the child for a while.

I don't know what Yang Guan replied, but the next letter was to thank the doctor he introduced, saying that she had already had surgery and the child was sent to the countryside to be taken care of by her mother.

At the same time, there was a receipt of a remittance slip in the letter, which was from Yang Guan to his ex-wife, with the amount ranging from a few hundred to a few thousand.

The third letter was newer, so it should be more recent.

"...The doctor has confirmed that she has cancer. She has about a year to live. I have decided to give up treatment and leave my savings to my daughter...After I die, you have to take good care of my daughter...Attached to this letter is a recent photo

of my daughter. You have forgotten what she looks like, right? We all owe her so much..." The letter was not long. They read it quickly and searched through the boxes and cabinets for the photo. But after opening all the letters and documents, they did not find the photo sent by his ex-wife.

Officer Liang was so excited that his hair stood on end: "She took the photo!"

"Maybe she hid it. It would be very troublesome if the painter found the photo of the girl." Jian Jing said so, and she was 70% or 80% sure in her heart.

She had already guessed the identity of the murderer.

President Tao did not expect Jian Jing to come to him alone. He was surprised and puzzled: "Is there something wrong?"

"President Tao said before that he can come to you anytime," Jian Jing looked at her watch, "Although it's a little late now, it's urgent. Can we talk?"

President Tao said those words for show at the time. He didn't think he could pry her around, but then he thought, could it be that Kang Mucheng got into trouble and she came to find another buyer? He

immediately became energetic and opened the door to invite her in: "Of course, please come in."

He asked warmly and cordially: "Jingjing, why did you come to me at this time? Do you need my help? Just say it, I will help you if I can, don't be polite with me."

"I want to ask President Tao, how do Morning Star sign writers?" Jian Jing smiled.

There is drama.

Mr. Tao suppressed his excitement of catching fish and said amiably, "Sometimes it's a competition, sometimes it's a submission, but these are all newcomers. Those who have published works will definitely be given preferential treatment, and royalties and other things will be easy to negotiate."

Jian Jing pretended to be curious: "How did Xia Xing sign with you? I heard that her first book was very good."

"An old friend recommended her. She said she was the daughter of a friend. She showed me the manuscript and it was really good, so I signed her." Mr. Tao paused and hinted, "But no matter how good her conditions were, she was also a newcomer at the time. If Jing Jing was willing to come, I would definitely convince the boss to give you the best treatment."

Jian Jing held back her laughter: "Thank you, Mr. Tao, it's very late, I won't disturb your rest."

"Nothing, I sleep late." It was too late, and Mr. Tao didn't want to keep her any longer, so he made some free promises before sending her out.

Jian Jing said goodbye to Mr. Tao, turned a corner, and knocked on Xia Tianxin's door.

She quickly opened the door.

"Are you still awake?" Jian Jing asked.

Xia Tianxin invited her in and said with a smile, "I'm rushing to finish the manuscript. I just sent the last chapter of the new book to the editor."

Jian Jing stared at her face and asked softly, "Why are you rushing to finish the manuscript so late?"

"Finish it sooner, and you'll feel at ease sooner." Xia Tianxin smiled, "Why do you want to see me so late?"

Jian Jing didn't say anything.

Xia Tianxin also calmed down.

A strange silence brewed between the two girls, like a silent spell.

After a long time, Jian Jing said, "You might be more successful than me if you write mystery novels."

"Why?"

"You have talent," Jian Jing turned her head and looked at her, "if you use it in the right place."

Xia Xing raised her eyebrows, her eyes sparkling, and she seemed happy from the bottom of her heart: "Really? But I'm definitely not as good as you. If I were better than you, you wouldn't be here."

"Do you admit it?" Jian Jing asked.

Xia Xing smiled: "I have read many mystery novels, and almost every author warns readers that there is no perfect crime in the world. Although I think I have not left any flaws, when I saw you, I knew you knew it."

Jian Jing frowned: "You do this..."

"Do you know the difference between mystery and romance?" Xia Xing interrupted her, "Mystery focuses on logic, but romance focuses on this."

She pointed to her chest and said slowly: "Love someone, even if he has a thousand faults, like is like, can not deny, hate a person the same."

Jian Jing was silent.

"OK, I have finished sharing my creative experience." Xia Xing made an invitation gesture, "It's your turn. Please start from the beginning, I will be a good listener."
