"The words of chalk are indeed reminiscent of teachers." Bella said.

"Is it a tutor or a school teacher?"

"What do you think?"

"As far as I know, there are several schools in Paris where no aristocratic girl will teach."

"But governesses don't usually use chalk, do they?"

Usually when you need to present on the blackboard, you will only use chalk and other things.

"That's right......," Elena thought for a moment, "but who else but the teacher would have access to chalk?"

"Could it be a tailor?" Margaret speculated that "tailors need to draw lines on the fabric, and sometimes chalk is used."

"Yes, it's possible for a tailor." Elena said.

Bella, however, shook her head.

"Unlikely." "Tailors use chalk, though, but it never gets on handkerchiefs."

"Huh? Why is that?" Elena didn't understand.

"According to our analysis just now, the material of this handkerchief is not affordable for ordinary people, so the other party's family background must be very superior. Later, we speculated and came to the conclusion that it might be a gift from someone else. Despite this, we can still judge by the residual perfume smell on it, and this lady is definitely not low. Elena should have made a discovery, right?"

When it comes to perfume research, Elena is an expert.

"That's right." Elena said, "It's true that the perfume on it isn't your average product. However, if the handkerchief was given by someone else, then the perfume may have been given, right?"

"No, it won't." Bella said, "The fact that the smell of the handkerchief has not dissipated since Margaret picked it up and when she took it shows that the perfume has been lingering for a long time. In other words, the other party must use perfume regularly. And although the handkerchief was carried on the body, he was reluctant to use it. If it was also a gift from a lover, perfume is a consumable item compared to a handkerchief, so it must be more reluctant to use it, right?"

"Makes sense." Elena nodded knowingly.

"On the other hand," Bella continued, "it doesn't matter if any of the aristocratic ladies of Paris are tailors, and even if they are, they don't usually wear perfume when they are working. Because that will allow the flavor to get on top of the material. And when you wear perfume, you don't go to work. In other words, the perfume of chalk and handkerchief is not able to coexist. Since this person attaches so much importance to this handkerchief, he probably wouldn't use it to wipe the chalk dust, right?"

"But if you're not a tailor, who could it be?" Elena said.

"From the level of detail of this chalk powder, it can be seen that the quality is not too low, and only the University of Paris can afford to use it in this area." Bella said.

"Could it be that you are a teacher at the University of Paris?" Elena asked, "However, most of the teachers at the University of Paris are men, and even if they are not aristocratic ladies, there are only a few female teachers, and there doesn't seem to be a 'S' start, right?"

"Does it have to be a teacher?"

"Huh? Is it a student?" Elena was surprised and said, "Teacher-student love?"

"I don't think it's likely to be a student." Bella explained, "If you're a student at school, wouldn't you be able to see your teacher every day? Why do you need to bring it with you when you meet?"

"In that case, who could it be?"

"Let's rethink our thinking." "First of all, the clues we have now. The handkerchief is of good quality, the materials and the embroidery are of the highest quality, so I conclude that the person who buys or customizes it must have a very good family. Judging from the residual smell of the perfume on it, the user must also be a prominent aristocratic lady. And according to the newness of the handkerchief, we speculate that the other party may have cherished the handkerchief very much, and although it is outdated, it still refuses to abandon it. Well, maybe it's a gift from a loved one. From the end of the chalk above, we deduce that the other party is likely to be engaged in the education industry, or at least have access to chalk. And this kind of fine chalk is currently only used by the University of Paris, so in other words, it is very likely that the owner is at the University of Paris."

"And who is the owner?"

"Well, I don't think it's likely to be a teacher or a student." "While teachers and students are associated in normal schools, these people aren't the only ones these days," Bella said.

"What do you mean...... There is an open class recently that everyone can go?"

"That's right," Bella said, "and this kind of public speaking is done regularly. Let's imagine that a noble lady falls in love with a university professor and wants to go to his class every time she has the opportunity. Over time, the professor fell in love with the little girl. Later, on the girl's birthday, or some other important day, he gave her a handkerchief embroidered with her initials. The girl was very happy, and she always carried it close to her, but she was reluctant to use it. Until one day after class, she saw some chalk on his face, so she took out this handkerchief and wiped it for him, so the handkerchief was stained with chalk. And it happened to be the time for a public lecture to-day, so the girl hurried over, and accidentally left a handkerchief on the way, and Margaret picked it up."

"That's right......" Margaret nodded thoughtfully.

"But that's all just speculation. Maybe it's really a rich lady, and she doesn't want it when she gets tired of it, or she doesn't feel distressed if she loses it, but in fact it doesn't have any special significance. It's just our cranky thinking here." Bella smiled helplessly.

"Is that so?" Elena still didn't want to give up, "Is there really nothing you can do?"

Several people studied here for a long time, but to no avail, with Elena's character, they all felt unwilling.

She picked up the handkerchief again and looked at it carefully for a while, but she still couldn't think of anything more valuable.

Just then, Madame Roland walked in.

Seeing Bella and the others gathering in everything to gossip, she also leaned over to take a look.

"Huh? This handkerchief," said Madame Roland suddenly, "I seem to have seen it somewhere......

"Huh? Do you recognize it?" Elena asked, surprised.

"Hmm." Madame Roland nodded, "I remember that two months ago, Mr. Pascal of the University of Paris asked me to help me choose. He was preparing a public lecture at school when he received a letter saying that his cousin from his hometown was coming to visit him. So, she asked me what I would like to give as a gift, and I chose this handkerchief for her. It was very popular at the time! Since his cousin's name is Susanna, there is an "S" embroidered on it. But his cousin soon returned. Anyway, Mr. Pascal seems to have a speech today, is Suzanne also here? …… I said, you, why are you looking at me with such amazement?"

"Bella," Elena said lightly, "I think you should read less romance novels."
