The fairy maid cheers for her deceased master today.

Based on these dimensions, Ax conducted a preliminary analysis.

"Now, we can see some interesting patterns."

Ex pointed to the contents of the white paper and said.

"Let's start with the most crucial point. The geographical elements in Reasoning Passages 1 and 4 are widely distributed, covering almost all of London's iconic locations, which seems like misleading information deliberately added by someone. Reasoning Passages 2 and 3, on the other hand, are more focused, concentrating on specific areas or elements."

If Catherine is to leave clues, especially the most important location clues, then the geographical elements provided should not be scattered.

At that moment, she must have been thinking about leaving behind the most useful clues before her consciousness completely collapsed.

Geographical elements that are too scattered are not useful clues.

After listening to Ax's idea, Elena also started to think in the same way.

She was feeling better now, so her thinking became quicker, and she added:

"Furthermore, in terms of emotional tone, the first and fourth mystery stories are more fantastical and surreal, while the second and third mystery stories have some melancholic or fluid qualities."

"If... considering Catherine's imprisonment, her true feelings are probably closer to the latter."

She would write down her subconscious feelings under the influence of the drug. And those feelings at the time were certainly not pleasant.

Ax nodded in agreement: "Another important point is the logical structure. The logic in Reasoning Passage 1 and Reasoning Passage 4 is more jumpy and self-contradictory, which may be a deliberate attempt to create confusion by the kidnappers."

"While the second and third mystery stories also contain absurd elements, they exhibit a certain coherence in some paragraphs, which is more consistent with the actual thought patterns under the initial influence of hallucinogens."

Thus, after further analysis, X and Elena concluded:

The second and third mystery passages are likely genuine mystery passages written by Catherine under the influence of hallucinogens, while the first and fourth mystery passages are misleading content written by the kidnappers.

"Oh! So we found Catherine's article!"

Angel said happily.

However, X and Elena exchanged a glance and shook their heads simultaneously.

"Why!?"

"Angel, this is just a bold hypothesis. It's the most probable possibility, not a 100% certainty."

As Axe said, this is just a bold assumption.

There's not even any evidence; it seems more like a gut feeling.

However, further verification is needed using other clues.

Ax pondered again, trying to see if he had overlooked anything.

Angel looked at the blank paper, then at X: "Master, what are you looking for?"

"More conclusive evidence."

"Then I'll help too!"

Angel immediately placed the book she had just read, "Mysterious Botany: Studies of Hallucinogenic and Medicinal Plants," in front of her.

Start reading it aloud in a low voice.

"...After being processed using a specific technique, the leaves of this plant can be extracted and prepared into a potent hallucinogen. This hallucinogen can induce a persistent dream state, causing severe mental disorder, which in turn makes individuals more likely to reveal their inner concerns... However, because the expressions it induces are mostly illogical nonsense, it is difficult to use as a truth serum in practice."

It seems that Angel wants to understand the effects of this hallucinogen more clearly before helping with the analysis.

However, what she recited... was exactly what Elena had just recalled.

Since both of them mentioned this passage, X's thoughts inevitably drifted to it as well.

"...to prompt individuals...to reveal their innermost concerns..."

"If it were Catherine, what would be her biggest concern?"

Thinking of this, Ax's eyes lit up instantly, and he took the article back to his face and compared it carefully.

Angel leaned closer curiously: "What's wrong all of a sudden?"

"No, it's nothing! You're a genius!"

X pulled Angel's head towards him and kissed her on the forehead.

Then he immediately put the blushing Angel aside and picked up the two articles.

"We have clues that we can cross-verify!"

"How so, Sir Ax?" Elena asked.

"What do you think is the thing that Catherine thinks about most in her daily life?"

"This...case?" Elena asked softly.

Angel's head was still overheating and evaporating, so she didn't join the conversation.

"Let me rephrase the question: What is the item she most longs for...?"

Upon hearing this question, Irene realized what was going on.

"Lucky gloves! Catherine looks for her lucky gloves every day! To be honest, it's a bit superstitious."

How dare you, a fortune cookie enthusiast, talk about Catherine!

However, you were right.

"Yes, so according to the description of this hallucinogenic drug, it will make her subconsciously vomit up what she cares about most... namely, the lucky glove."

Irene immediately picked up the parchment, glanced at it, and then pointed out:

"It was mentioned in the second article!"

The first paragraph of the second passage: My room is small, yet large. The walls are red, like roses, but they feel cold to the touch even with gloves on, because they are made of ice. No, they are made of brick, Victorian brick, each with a different pattern.

Clearly, the word "gloves" is mentioned directly here.

"But, Sir Axe, none of the other articles mention it. We can only assume that the second one was written by Catherine?"

"No, it's mentioned in the third article too. You see—"

The first paragraph of the third part: As before, the man in black injected me with a drug and then immediately made me deduce. My hand told me to keep it short.

Here, "my hand," according to the meaning of the sentence, doesn't actually refer to one's own hand, because it's not part of oneself. Therefore, it should be something external—namely, "gloves."

When your mind is in a state of confusion, using your fingers as a substitute for a glove is actually quite natural.

In other articles, there wasn't even a mention of "hands".

Thus, through cross-validation, it can be almost certain that the second and third articles were written by Catherine.

Once Catherine's article is identified, the information contained in both articles is sufficient to deduce the location.

“Let’s continue our analysis from passage two,” Axe said. “This passage mentions several key elements: red brick walls, blue roses, ruins, underground tunnels, and East London and the Whitechapel district.”

Ex originally wanted to ask Angel to bring the map over.

However, Angel's head was still spinning, so Elena grabbed the map and unfolded it.

As seen on the map, East London is indeed a concentration of slums and industrial areas. Whitechapel, as part of East London, is characterized by dense buildings and narrow streets, which aligns with the ruins and slums mentioned in the text.

Furthermore, the text mentions that "the patterns on the brick walls point to East London." Indeed, the decorative patterns on brick walls in architecture of this era reflected regional characteristics. Industrial buildings and slums in East London typically used simple, practical brick walls, while wealthier areas in West London used more decorative brickwork.

"So, the 'blue rose' might be a metaphor."

Elena pondered.

"Under the influence of hallucinogens, Catherine may be hallucinating a certain element she actually sees as a blue rose. Considering the environment in which she was imprisoned..."

"From inside the room, looking out at the rows of buildings, what could possibly be blue?"

"Blue glass!" These days, there aren't many blue items used in architecture. Even on the streets and alleys, there aren't many eye-catching blue things.

Blue, and it was very conspicuous that Catherine saw it... so it was most likely glass.

"Another important clue is the 'underground tunnel'," Axe added, "but I highly doubt whether the place where Catherine was imprisoned could see the underground tunnel. Let's assume for now that it's a complete hallucination."

Next, they turned to the third mystery.
