Su Tong's eyes were dazed for a moment, but she quickly came back to her senses, "It's nothing......" She just thought of Wan Qian unconsciously.

When Wan Qian just left, she was also like Bai Mu's current state, she didn't dare to look at things related to Wan Qian, for fear that she would be unable to control her emotions.

"Really?" Xu Sa was suspicious, "Su Tong, don't lie to me." ”

"It's my right to say anything." Su Tong frowned, a little irritable in his heart, bypassing Xu Sa and walking towards the dressing table in the room, "If you don't want to investigate the case, you can go back, I can do it myself." ”

Looking at her back, Xu Sa frowned, and after all, he didn't speak.

Bai Xue's dresser is very neat and tidy, just like the description of her personality in the data, and she is a very self-disciplined girl.

Such a girl's interpersonal relationships will be relatively simple, and if someone suddenly appears in her circle, she will never be able to hide it from her family or friends around her.

However, through their investigation, they found nothing, which Su Tong always felt very strange.

There were not many cosmetics on the dresser, and I could see them at a glance, and I didn't find the same perfume as the second victim.

Su Tong opened the cabinets one by one and inspected them again, although those places had been inspected before, but according to the style of the investigation team, there was nothing particularly suspicious, and they would not make a record.

This is also why, Su Tong thought about running again.

Xu Sa stood quietly behind her for a while, then turned to look for another place.

Ten minutes later, Xu Sa dragged out a dusty box from under the bed.

"Su Tong!"

Xu Sa hurriedly brought the box to the table, he had a hunch that it was likely to be what they were looking for.

"This is ......" Su Tong closed the door of the wardrobe and leaned over, "Where did you find it?" ”

Xu Sa pointed under the bed, "I also had a whim, everyone has their own secrets, but they are hidden in different ways." For a child like Bai Xue, who has been a good girl since she was a child, the way to hide things is often very simple. ”

"......" Su Tong looked at Xu Sa silently, and sometimes she had to admit that the intuition of the man in front of her was terrifying.

"Did you suddenly think I was handsome?" Xu Sa carefully opened the box with gloves and said without raising his head.

Su Tong had the illusion of being arrested, looked away in a panic, and changed the topic in a thick voice, "Can you move faster!" ”

"Absolutely." The corners of Xu Sa's mouth hooked up a smile, and he replied with kindness, and at the same time accelerated the movements of his hands.

Seeing that Xu Sa was not holding on to the topic just now, Su Tong breathed a sigh of relief.

There were several layers of the box, and the outermost layer was covered with dust, and it could be seen that it had been placed under the bed for some time.

After unpacking the outer three layers, a familiar box appeared in their sight.

Su Tong and Xu Sa glanced at each other, it was the perfume box they found at the second victim yesterday.

"Open it." Su Tong's eyes were slightly condensed, very good, it seems that the thing has not been destroyed by the murderer.

Xu Sa nodded, opened the last layer of paper cover, and a bottle of exquisite perfume lay in place, exuding a faint fragrance alone.

The smell is exactly the same as Xu Sa's.

"I'll call Bai Xue's mother in right away to see if she knows who gave this bottle of perfume!" Xu Sa's words are categorical.

It is very likely that Su Tongjue's mother didn't know about the existence of this bottle of perfume at all, but it didn't stop Xu Sa.

After all, now they have no other clues in their hands other than this.

After a while, Bai Mu followed Xu Sa in, and was very surprised when she saw the perfume on the table.

"Xiaoxue, she never uses perfume!" Bai Mu looked at the two of them suspiciously, "Two police officers, is this really from under the small snow bed?" ”

"Auntie, don't get excited." Su Tong smiled comfortingly at Bai Mu, "Maybe this was given to her by a friend of Bai Xue, do you recall, has Xiaoxue received any gifts recently?" ”

Bai Mu pulled her hands anxiously, "Xiaoxue's friends are impossible, that child doesn't have many friends, they all know her preferences, and they won't give these things." ”

"But ......" Bai Mu paused slightly when she said this, and a trace of hesitation flashed in her eyes.

"But what?" Xu Sa asked keenly, "Auntie, even if there is anything wrong, you can tell it, and that is probably the key to finding the murderer." ”

Bai Mu was slightly startled, "Officer Xu, do you mean that this perfume was given to Xiaoxue by the murderer?" ”

Xu Sa's expression was slightly restrained, and he said solemnly, "At present, it is still our suspicion. ”

The white mother leaned and almost fainted, but fortunately, Su Tong on the side quickly caught the person.

"Auntie, are you alright?" Su Tong glared at Xu Sa reproachfully.

"I, I'm fine...... Bai Mu rubbed her forehead weakly, and said intermittently, "I really don't know who sent this thing, Xiaoxue's birthday last month, there were a lot of couriers at home, I think this perfume should be mixed with that batch of couriers." ”

"At that time, I thought that the courier was for Xiaoxue, so I didn't open any of them." Bai Mu cried as she spoke, "If I had some ideas and dismantled the things earlier, maybe I would have found this perfume, wouldn't my Xiaoxue have to die?" ”

The mournful cry of the white mother echoed in the bedroom, which made people very uncomfortable to hear.

After obtaining Bai Mu's consent, Xu Sa put the perfume and the box into the evidence bag, ready to take it back to the forensic department of the bureau to see if he could find out anything else.

Su Tong chatted with Bai Mu for a long time, and waited until Bai Mu's mood stabilized before leaving.

The two of them sat in the car, and their hearts were a little heavy.

"The clue is still broken." I don't know when a light rain fell in the sky, Su Tong looked at the raindrops hitting the car window and muttered.

"Not necessarily." Xu Sa said while taking out his mobile phone, "I plan to let everyone check this line of the express." ”

"It's useless." Su Tong faintly denied, "The second victim's perfume was sent by the perfume shop owner, and Bai Xue's must be the same." ”

"Really? I don't think so. Xu Sa raised an eyebrow at her, "Otherwise, let's make a bet." ”

"Not in the mood." Su Tong sat up straight and turned around to tie his seat belt. Somehow, the sudden rain at this time gave her a rather bad premonition.

"Why, you don't dare?" Xu Sa didn't let her go, leaned forward, and just stopped her movements, "Are you afraid of losing to me?" After speaking, he smiled brightly at Su Tong.

"Xu Sa!" Su Tong glared at him angrily, "When is it, are you still in the mood to joke!" ”
