Just a Defense Against the Dark Arts Professor

Sherlock listened to the three pieces of information she read out, his face was a little confused.

"What does this mean?"

Silk cleaned up the poker cards on the table, leaving only an eight of diamonds.

"A location in the castle, as I said yesterday, its original intention is for us to find it. It has no interest in these students in Hogwarts, and has no other ideas. It just wants to find you."

"But if it's just revenge, it shouldn't be so eager." She said softly, with a hint of confusion in her voice.

Sherlock had no intention of exploring the intentions and purposes of the scarecrow. The most important thing now is to solve the problem before the matter has expanded and the news has not spread.

This year is not like the year when the secret room was opened. If it ends up to the point of closing the school, the consequences will undoubtedly be more serious.

"The number eight..." Sherlock picked up the poker card left by Silk, pinched his chin and looked at it, "What could this mean? Time? Eight or eight o'clock? Or location? The eighth classroom? The eighth floor? Or the eighth tower?"

Silk has much more experience than Sherlock in solving puzzles.

"The possibility of the time is very small. If it indicates the 8th or 8 o'clock, it will not be connected with the clues later. The white color and a hidden room are more likely to indicate the location."

With Silk pointing out the general direction, they have a target for the next investigation.

Sherlock originally had two sixth-grade classes in the morning. In order to save time, he could only ask Moody to help him. Because Silk's arithmetic divination class is an elective course for third-grade students, her workload is much lighter than Sherlock's. Even if she has classes today, she can temporarily adjust to other times.

They came to the first floor of the castle and started looking from the eighth classroom. According to the eighth classroom they encountered after entering the castle, they went along the corridor and found a small empty classroom.

But this room is very ordinary, and there is not even a chair or bench. It looks like a potion classroom that is occasionally used. Sherlock and the others checked every corner here and found nothing.

"The eighth classroom is wrong, maybe it's the eighth floor? But isn't this range a bit too large? There are quite a few classrooms and offices on that whole floor. I remember Filch also found two rooms there to be used as utility rooms." Sherlock and Silk walked up the stairs to the eighth floor, saying with a headache. Silk's face did not show as much tangled expression as he did. For her, who has become accustomed to solving prophecies, this puzzle is not too worrying. "It is very likely to represent the eighth floor, because there are three clues, and the number eight is only the first clue. The wider the range it represents, the more likely it is the answer, because the latter two clues can play a role in streamlining. All the results of the prophecy have never been useless. Ignoring any of the details, the final result is often very different." "There are still students in class. Do we have to search one classroom after another?" Silk turned her head and looked at Sherlock with her eyes covered by a black ribbon. "Are you not good at solving puzzles?" Sherlock touched his forehead. "Well, I admit that I lack some patience, because I can't predict what will happen if the student's nightmare continues, after all, it used to kill people without scruples."

"You don't have to search classroom by classroom, pay attention to the two pieces of information at the back, white and a hidden room."

Hilke could see that Sherlock was a little worried now. He has been teaching in this castle for the third year and has long had feelings for Hogwarts.

That's why she needs to be calmer.

She looked at the decorations around the castle. As a castle built in the tenth century, even after many renovations and renovations, the walls in Hogwarts are still not painted or sprayed with paint, and are always the original color of the stone.

It's gray, and even if the sun shines in, it will give people a unique sense of depression when staying in the castle.

Most of the decorative paintings hanging on the wall are oil paintings and portraits, with rich colors. There are short knights riding horses and shouting constantly, noble ladies holding cats and smiling, and monks holding crosses with compassion.

It is difficult to find information related to white, not only on the walls but also on the decorative paintings.

So the second hint "white" should be the most important.

According to Silk's previous experience in deciphering prophecies, the number eight determines a large range, and white is obviously to determine a clear direction within this range. The last hint directly indicates the answer itself.

"You have been in Hogwarts longer than me. Do you know if there are any paintings or walls with white as the main color on the eighth floor?"

With such a clear hint, Sherlock only thought for a moment and remembered a painting.

"There is a tapestry of a troll beating Barnabas with a stick! Barnabas is wearing a white ballet skirt, and the theme color of the tapestry is white."

"Where are we going!"

Soon, they came to the tapestry.

This is a very humorous tapestry painting. Barnabas in a ballet skirt seems to want to teach the troll to dance, but the troll raised the wooden stick in his hand high and prepared to hit his head.

Barnabas in the painting looked very embarrassed. When Sherlock and Silk came here, the giant holding a wooden stick turned his eyes to them, staring with his eyes and bulging his nostrils.

Sherlock certainly didn't feel like paying attention to the giant in the portrait. He looked around the tapestry. He might not have noticed anything if he didn't pay attention to it at other times, but now that he came here specifically, he would find something wrong.

Opposite the tapestry, there was a wall that looked a bit abrupt. This wall was very ordinary, no different from other walls in the castle, but its location was a bit wrong.

This was neither the end of the corridor nor the corner of the stairs, so leaving such a place seemed redundant.

Although there were many such redundant places in Hogwarts Castle, those walls would simply hang a few moving paintings to decorate them, or simply place a statue directly.

This wall was blank, with nothing on it, as if such a place was deliberately left.

Sherlock frowned and looked at the wall opposite the tapestry, muttering the last hint.

"A hidden house... A hidden house..."
