Xu Sa took Su Tongjing to a family. It wasn't until someone came to open the door that Su Tong knew that Xu Sa had brought her to the victim's parents' house.

Sitting down, Xu Sa took the scarf to them for identification, and the victim's mother recognized the scarf at a glance.

"I know this scarf, it was a gift from my daughter the other day, and she was so happy. I thought she was in love, it was given to her by her boyfriend, and she didn't say anything to us, so I didn't ask more. The victim's mother grabbed the scarf and said in a firm tone.

"Have you ever met your daughter's boyfriend?" Xu Sa asked suspiciously.

"Nope." The victim's mother shook her head, "It's just that on the day of my daughter's accident, she went out after dressing up carefully, and she was wearing this scarf, and she must have gone to see the person who gave her something." “

Thinking of this, the victim's mother was a little excited, and she grabbed Xu Sa's hand, "Officer Xu, is that person related to my daughter's death, did he kill my daughter?" “

Su Tong on the side hurriedly stepped forward to calm her emotions, "Auntie, don't worry, we are investigating step by step now." You can rest assured that we will bring the murderer to justice, you have to pay attention to your body, and your daughter doesn't want to look at you like this. “

Speaking of her daughter, the victim's mother couldn't help but sobbed in a low voice, and Su Tong could only hold her hand quietly and give her silent comfort.

"Can I see your daughter's room?" Xu Sa put away the scarf and lowered his head to ask the victim's mother.

She nodded, Xu Sa glanced at Su Tong, Su Tong knew what he meant, so she got up and followed him into the room.

As soon as he entered the door, Su Tong noticed a delicate box on the dresser, and there was a courier note on it.

Su Tong took the courier order to Xu Sa, "There is no name, no address, only this perfume shop that forwards." “

Xu Sa watched the courier bill repeatedly, and said a little jokingly, "A courier bill without a name and address, the victim knows who sent the gift, it seems that their relationship is indeed extraordinary." “

Su Tong didn't say anything, but Xu Sa's idea was very correct.

"Let's go, let's go to this perfume shop."

The owner of the perfume shop seems to be a very honest person, and he answers their inquiries normally.

"I'm only here to help some couriers do forwarding, and we don't have the right to ask for those people's information."

Xu Sa asked to check the surveillance video of that day, and the boss readily agreed, and soon the surveillance was also called up.

There was suddenly business in the store, the boss was busy, and Su Tong and Xu Sa were watching the video on the spot.

A man appeared in the surveillance in a black suit, and he also wore a top hat, so he couldn't see his face at all, and his body looked like a man in his thirties and forties.

"Boss, what is this person doing in your store?" Su Tong subconsciously turned around and asked.

When the boss heard it, he came over and took a look, and his memory was a little vague, "My store sells perfume, of course he came to see perfume." “

Su Tong sighed with some regret, "Could it be that this clue is broken like this?" Su Tong really felt a little unwilling.

Xu Sa raised her hand and silently lowered her head, "Okay, don't be in a hurry, you go out and wait for me first, and I'll come to the toilet when I go to the toilet." “

Su Tong nodded, and then walked out of the store.

And Xu Sa, who originally said to go to the toilet, did not go to the toilet, but walked to the boss on the side, "Boss, did the man we asked you just now buy perfume in your store?" Get me a bottle too. “

When the boss heard this, he took a bottle of the same to Xu Sa, Xu Sa looked at the perfume in his hand with deep eyes, put it away, and walked out.

Su Tong looked at the perfume in Xu Sa's hand, felt a little funny, and couldn't help but joke to him, "When did you still like perfume." “

Xu Sa didn't say anything, just smiled and didn't speak.

Then, Xu Sa drove to the location of the first case, and after the two investigated, they found nothing, and Su Tong's frustration was even greater.

After Su Tong left, Xu Sa took out the perfume he had just bought and sprayed some on the ground, with a faint smile on the corner of his mouth, and then left with him and sent Su Tong home.

Su Tong fell asleep early tonight, thinking that he would have insomnia, but for some reason, his body felt extremely tired, and he fell asleep not long after lying down

In the middle of the night, a rapid phone rang, and Su Tong turned over a little helplessly, but the ringtone still rang unrelentingly, as if it was about to break through Su Tong's eardrum.

She reached out and picked it up subconsciously, but her mind was not yet clear.

There was only a female voice singing a lullaby on the phone, Su Tong opened his eyes suddenly, the whole room was dark, and the voice of the phone was still ringing.

"Knock knock, knock knock." A dull, orderly voice came. Someone in the bay window?! Su Tong's eyes widened and he looked at the window where the voice came, and his hairs exploded in an instant.

Their family lives on a high-rise floor and has no balcony, so how can anyone knock on the window outside? Thinking of this, Su Tong still had the courage to walk over.

She opened the curtains, and a woman with a face covered in blood hung upside down from the window, because of the wind, her forehead was hitting the window again and again, and the window was full of blood, meandering downward, Su Tong was so frightened that she retreated again and again.

She opened her eyes suddenly, gasping for air, her forehead and pillow half wet with her sweat. Looking at the ceiling, Su Tong realized that he was having a nightmare.

She turned her head to see that her phone was playing the dream lullaby on the bedside table......

Su Tong found that she couldn't sleep anymore, no matter what, as long as she closed her eyes, her mind was the scene in the dream just now, and she didn't dare to sleep anymore.

When it was dawn, she simply got up, but she didn't sleep all night, and at the moment she felt that her eyelids were very heavy, and her mind was becoming less and less clear.

It's just a nightmare, and Su Tong really can't figure out why he has such a nightmare.

Su Tong was the first to come to the office, she felt uncomfortable, so she lay on the table and took a nap until someone gently pushed her a few times.

Su Tong raised his head and saw that it was Xu Sa.

"You're here."

Xu Sa looked at Su Tong's pale face and was a little worried, "What's wrong with you, do you feel uncomfortable there?" As he spoke, Xu Sa reached out and covered Su Tong's forehead.

"I'm not sick, I just didn't have a good rest yesterday, you don't have to worry."

After confirming that Su Tong did not have a fever, Xu Sa was a little relieved, but Su Tong's lack of energy still made him unable to feel at ease.

Su Tong adjusted his mentality, and after resting for a while, he felt much more comfortable, so he stood up to get some cups and go to fetch water to drink.

But after taking a few steps, she suddenly stopped and looked back at Xu Sa, feeling inexplicable, "Xu Sa, are you wearing perfume today?" “
