"That...... Why is this so? Could it be that there are two groups of people who want to do something against the French minister?"

Elena tried to come up with an explanation, but she soon vetoed it herself.

"No, probably not." Elena shook her head, "When everyone entered, they were strictly searched. Whether it is a firearm or a sharp weapon, it will be confiscated. And if someone uses a wand to cast a spell, it is impossible for the people around them to be unaware, so cutting off the lighting will be meaningless."

"That's right." "And if you do it in the dark, there's a big risk of missing. Because it's hard to make sure that everyone stays where they are, and if they make a mistake, they will inevitably expose themselves."

"In this case, it is unlikely that you can take advantage of the darkness to poison the cup." Elena said.

At that time, there was no problem with the remaining red wine in the bottle, so it was suspected that the problem was with the glass in the minister's hand.

"It's impossible, I guess so." Bella said.

"Huh?"

"Remember last night, when the Duke of Dolfo raised his glass and was about to drink, the power suddenly went off in the hall, right? Think about it, what would you do if you were halfway through your drink and suddenly it was pitch black?"

"I...... It's time to stop."

"That's right, the knee-jerk reaction of humans is to instinctively be on the lookout for possible dangers around them. Under these circumstances, it's hard to imagine that he would be able to drink with composure." Bella continued, "And if he really does this, the other party won't have time to poison him, right?"

Because when the lights were restored, Dulfo had already fallen to the ground.

"So, it's natural that there is no poison in the wine?" Elena said.

"Hmm." Bella nodded.

Poor Mr. Holder!

"That...... How, exactly, did you do that?" Elena still couldn't figure it out.

At this point, Bella just laughed and didn't say anything.

Today, the guards of Schönbrunn Palace are much stronger than before.

Sister Carlos and Elena went out for a walk together after dinner and unknowingly came to the city of Vienna.

Passing by the entrance of the theater, I saw Mr. Amadeus feeding the pigeons in the square.

The morning sun shines on the bubbling spring in the center of the square, making the summer air feel less impetuous.

A light breeze blows through the leaves on the roadside, making a rustling sound.

Amadeus crouched on the ground, surrounded by a flock of white pigeons.

After scattering the food in his hand, he slowly stood up, took out a quaint violin from the suitcase beside him, and placed it on his shoulder.

After a little adjustment, Amadeus stood in the middle of a flock of pigeons and began to play.

Melodious sounds wafted over the square, attracting not only pigeons, but also many pedestrians stopping to admire.

The music rode the breeze and dispersed. Walk through the streets and crowds, around the buildings, and finally into the crystal clear waters of the Danube.

At the end of the song, he noticed Bella and the others not far away.

Amadeus waved the bowstring in his hand, greeted them warmly, and made a big movement to startle the pigeons around him.

"I didn't expect you to get along so well with them." Bella said.

"It's not just humans who understand the true meaning of music." Amadeus replied, "Animals are also spiritual."

"Huh? Do they understand it?" Elena asked.

"I don't know." Amadeus said, "However, music exists in nature itself, and we humans just use it. Since they are a product of nature, animals should be as appreciative as humans."

"Looks like they like your sound."

"At least I don't hate them, because I just fed them." Amadeus smiled, "Actually, there are many unnoticed instruments around us all the time."

"Musical instruments around you?"

"For example, the blowing of leaves in the breeze, the splash of rushing water, and the chirping of all kinds of birds and animals are all natural music of nature. And our first musical instruments were created by imitating the sounds of nature. Listen carefully—"

Just then, a horse-drawn carriage carrying goods passed by the side of the road.

"The pull of the reins between the cart and the horse, the friction between the axles and the collision between the wheels and the ground all have different scales. Together, they are like a walking symphony orchestra." Amadeus said, "And the sound is different in different states. It's like this car just passed, with a low tone and a thick voice, and it must be full of heavy cargo."

Bella and the others looked at the van that was moving away, thinking about Mr. Amadeus's words.

"But ......," said Elena, "look at the sign on the car, it looks like a truck that has just delivered drinks to Schönbrunn Palace?"

Just finished unloading, how can it be heavy?

"Elena," said Bella, "we'd better inform Mr. Holder of this."

The evening banquet is still held in the main hall of Schönbrunn Palace.

Again, as always, Prince Kaunitz presided over the ceremony, and then Empress Maria Theresa gave a speech. It's just that this time the appearance of the Duke of Durfo is missing.

Amadeus is still conducting the orchestra to cheer everyone on.

It was not until halfway through the banquet that Mr. Holder hurried in.

"How's it going?" Elena asked eagerly.

"Let me drink first." As he spoke, he took a glass of brandy and poured it down, not caring about any image etiquette at this time.

"You guessed it right." After a moment's pause, Holder spoke, "There's something strange about that carriage."

"It's a credit to Mr. Amadeus." Bella replied.

"I led people to follow them all the way to a small house in the forest on the outskirts. I did not dare to act rashly in order to avoid startling the snakes, so I lay in ambush all around, until in the evening, important people appeared."

"What character?" Elena asked.

"Wearing a black cloak with a scar on the back of his left hand."

"A scar on the back of your hand? Is it ......?"

"That's right, I also thought about it, it was probably the man in black who was in Venice and disguised himself as a traveling merchant to sell potions to Stephen."

At that time, Elena took Sister Bella, in order to investigate the matter of breaking the magic stone, and rescued Stephen who was framed in Venice. According to Stephen's description, the prisoner was a man in black with a stab wound to the back of his left hand, and the Austrian accent also matched this.

"And then?"

"Then we raided and tried to take them down in one fell swoop. But it didn't work out, that guy was so cunning that he let off a puff of smoke and disappeared."

Holder felt very sorry.

"Did you get it back?" Elena asked.

"Hmm." Holder nodded, "That house is actually a warehouse, and it's the stuff that's been lost recently. In addition to Barus, I also need some guns and gold and silver jewelry. It's so dangerous!"

"I was able to steal something from the heavily guarded Schönbrunn Palace, and it seems that the other party is not an ordinary person." Elena said.

"Damn, I didn't catch him!" Holder angrily slammed the table.

"But since the thing has been recovered, it can be regarded as a blessing in misfortune." Bella reassured.

At least as things stand, nothing substantial has been done.

"Three young ladies." Holder stood up suddenly and bowed solemnly, "There's something I want to ask you for."
