The morning mist slowly cleared as the sun rose in the east, and Conan leaned against the railing on the deck, looking out at the shoreline that was getting closer.

Xiaolan also accompanied him, with some salty sea breeze gently blowing her hair, adding a bit of dynamic beauty to her supple temperament. It's just that Conan, who is obsessed with decryption, doesn't notice the female companion around him, and his developed brain only has lines of neatly arranged words, ignoring the beautiful scenery around him.

Conan's attention is now entirely focused on the two teaser letters he received. After receiving a sudden report from Kogoro Mori, the Metropolitan Police Department immediately conducted an investigation into the invitation letter signed "Keiji Aso".

Preliminary investigation revealed that the invitation, like the previous Phantom of the Thief's teaser letter, came from Moonshadow Island. In addition, both letters involve the character "Keiji Aso", and the Metropolitan Police Department now suspects that there must be a connection between the two letters.

Mori Kogoro was expressing his reasoning at this time, "Two police officers, in fact, I think that the teaser letter signed by the Phantom of the Strange Thief is a forgery at all!" ”

Both Nakamori and Twilight pricked up their ears and listened carefully to Mori Kogoro's analysis.

"First of all, the teaser letter signed by the Phantom of the Monster Thieves. This letter is different in format from previous letters in that it does not reveal the crime of the target. What's more, the target on the teaser letter is still a dead man! ”

"And the way the advance letter is sent is different. Recall that in the past, where did the Phantom of the Thief first appear? ”

After thinking for a while, Nakamori Ginzo replied thoughtfully: "If you think about it carefully, the previous warning letters first appeared near the victims. ”

That's right, this time the notice letter was sent directly to the newspaper office, asking the media to publish it first! This is not like the style of the Phantom of the Thief, in the past, he used to deliver the teaser letter directly to the victim himself. ”

"Indeed...... It's not like the Phantom of the Thieves' style. Officer Twilight nodded in agreement, but then asked:

"But Brother Maori, why did the other party forge the advance letter?"

"I think the sender's purpose should be to lure the real Phantom of the Thief to Lunaris Island." Kogoro Maori pinched his chin and speculated, "It is very likely that the sender was suspicious of Keiji Aso's death, so he chose to forge a warning letter to attract the real Phantom of the Strange Thief to investigate the matter about Keiji Aso." ”

"Moreover, the forgery of the notice letter can also attract the attention of the police, and the Metropolitan Police Department will re-investigate the incident of Keiji Aso."

"The invitation letter sent to me should have the same purpose, to have me, a famous detective, come and investigate the cause of Keiji Aso's death. Wait a minute...... Could it be that the two letters were actually written by the same person? ”

Not bad, uncle. I didn't expect your reasoning skills to grow! Conan nodded in agreement, this time Mori Kogoro's reasoning was very different from what he thought, but he didn't think that the two letters were written by the same person.

There is a stark difference between the two letters, one is open to the public through the media, and the other is sent in a rather private way. And the second letter also specifically stated the time when Mori Kogoro was invited to come - the next full moon.

"And the purpose of the second letter may not be really as speculated by Uncle Maori, so that he can investigate the cause of Aso's death."

"On the night of the next full moon, there will be a shadow disappearing again on Lunaris Island, please investigate the reason......" Conan silently read the contents of the second letter in his mind, his brows furrowed.

"It's more like a crime notice than a warning letter published in the media...... Could it be that the target of the teaser letter, Keiji Aso, is actually an allusion to the signature of the second letter? ”

While Conan was still digging for the information on the teaser letter, Mori and the others had already begun to discuss the work arrangements after arriving on Lunaris Island.

"The Metropolitan Police Department has asked us to carry out our investigation normally." Officer Twilight said, "You don't have to pursue a secret search. ”

"Doesn't that really startle the snake?" Mori Kogoro didn't understand the Metropolitan Police Department's intentions, "What if the Monster Thief Phantom chooses to change the time of action in order to protect himself?" In that case, wouldn't our search be meaningless? ”

"But there is no point in secretly searching." Nakamori Ginzo sighed helplessly, "Because in terms of intelligence, we are far behind the Monster Thief Phantom. ”

"Think about the past cases, the Phantom of the Thief has always been able to detect crimes before we do, even potential crimes that haven't happened yet, he can see in advance. The Phantom of the Strange Thief must have a sophisticated and accurate intelligence network, and even if we search secretly, we may not be able to hide it from his eyes. ”

"And in the absence of clues, secret searches are also inefficient." Nakamori Ginzo went on to explain, "The Ekoda Museum has previously shown that the Phantom of the Strange Thief has a personal relationship with Kidd the Strange Thief, and it is very likely that they will cooperate with each other. And Kidd the Strange Thief is a master of disguise, able to perfectly imitate anyone's voice and shape. ”

"Then the Phantom of the Strange Thief who has a personal relationship with him can naturally be disguised as anyone. In my experience, a covert search simply won't work to crack such a disguise. ”

"Perhaps, the Phantom of the Thief is lurking on this ship right now!" After saying that, Nakamori Ginzo stretched out his hand and grabbed Maori Kogoro's face, causing the latter to cry out in pain again and again.

"Hurry up and let go!" Mori Kogoro shook off Nakamori Ginzo's hand, covered his face and shouted angrily, "What the hell do you want to do?" ”

"I just wanted to see if you were a thief in the Phantom disguise." Nakamori Ginzo didn't care about Mori Kogoro's cry of pain, "In my experience, this is the only way to uncover Kidd's disguise. Detective, if you think about it, can secret searches use this kind of verification? ”

Mori Kogoro, who couldn't refute it, could only turn his head and snort, and the bad feeling for Nakamori Ginzo in his heart added a little more.

"Anyway, the Metropolitan Police Department has already greeted the village chief of Moonshadow Island first. Moon Shadow Island will also fully cooperate with our investigation. Officer Twilight concludes, "Lunaris Island is extremely staffed, and the inhabitants are familiar with each other. Even if the Phantom of the Thief had to disguise, it probably wouldn't risk disguising the island's inhabitants, so we'll have to be more wary of recent visitors, as the Phantom is likely to be lurking among them. ”
