Conan and Yu Chengen glanced at each other and said puzzledly, "How do you know that someone has proved that he didn't leave the room?" If he had a witness, why did he lie? ”

Li Canghai looked at the two of them and said lightly: "Because the person who was in the same room with him was a concubine of Zhang Wenyuan, he didn't dare to say it." ”

"Qiu Ju?" Conan and Yu Chengen were extremely surprised, and said almost in unison.

But Conan immediately shook his head and said, "This is impossible, Qiu Ju is clearly in his room, how can he go to Ueda Takashi?" ”

Yu Chengen was also puzzled, and looked at Li Canghai suspiciously.

"The reason why the family thinks that Qiu Ju is in the room is because they see a shadow, but it is only a shadow. Just because it was Qiu Ju's room, they subconsciously thought that the shadow was Qiu Ju. However, they didn't see Qiu Ju with their own eyes, did they? Li Canghai said.

Conan nodded and muttered, "Yes, they didn't see Qiu Ju with their own eyes. But this doesn't prove that the shadow is not Qiu Ju. ”

Li Canghai smiled and said, "Brother Conan, you have overlooked the most important point. The two family members said that they patrolled back and forth several times, and the shadow always maintained the same posture from the time of the child to the time of the second hour. Just ask, for such a long time, who can stare motionless at the chessboard? ”

Conan thought carefully for a moment, and suddenly realized: "Yes, that shadow must be just a trick to make the family think that she has been in the room all along!" ”

Yu Chengen was a little puzzled, he looked at the two of them, scratched his head, and asked, "Forgive the little brother for being foolish, I don't understand the meaning of the two of them, if it wasn't Qiu Ju in the room, who would it be?" ”

Conan explained, "It's no one, because it's not a person. In fact, it is very simple, as long as you make a wooden frame, and then put your clothes on it, with the help of dim candlelight, you can make such an illusion. What's more, the patrol family couldn't see it really through the window, but this room was where Qiu Ju lived, and when they saw the shadow, they would naturally think that the shadow was Qiu Ju. ”

"I see!" Yu Chengen was stunned, but he immediately said puzzledly: "But, even if Qiu Ju is not in the room, how does Brother Li know that she is in Ueda Gaozhi's room?" ”

Li Canghai patted his neck with his fingers, and when he saw that the two of them were a little inexplicable, he said, "Do you remember what I said just now that there is an unclear kiss mark between Ueda Takashi's neck?" ”

Yu Chengen nodded and said, "So what?" ”

"From the lip marks left by the kiss marks, I deduced that the kiss marks belonged to Qiu Ju. In addition, when I asked her, her eyes wandered and she didn't dare to look at Zhang Wenyuan, and when Ueda Takashi spoke, he always looked at Qiu Ju with his spare eyes, intentionally or unintentionally, so I concluded that the two of them must have an ulterior secret. Li Canghai said lightly.

"You can deduce from the lip prints alone, who left it? That's amazing, isn't it? Yu Chengen's eyes widened, and he said incredibly.

Li Canghai smiled slightly and said, "Everyone's lips look similar, but in fact they are similar, as long as you look closely, you can find the difference." ”

Speaking of this, Li Canghai paused, and then said: "Actually, the reason why I think that lip print is owned by Qiu Ju is mainly because the lip grease that Qiu Ju uses to make up her lips is light pink in color, which is similar to the color of the light lip print on Ueda Takashi's neck, and among the many female dependents, Qiu Ju is the only one who uses this lip grease, so it is easy to think that it is owned by her." ”

After Yu Chengen listened, he couldn't help but praise Li Canghai's admiration for his five-body body: "Brother Li is really good eyesight!" Even such subtleties are observed so carefully, the little brother admires! Admire! ”

"Isn't that back to square one?" Conan frowned deeply.

The three fell silent at the same time, all of them had alibi evidence, who could the murderer be?

Li Canghai rubbed his eyebrows and said, "Let's put aside the identity of the murderer for the time being, let's talk about the murderer's murder methods first." ”

Conan nodded and said, "The windows of the whole room are closed, and the door is locked from the inside, so it can be said that it is a closed space. Now the question is, how did the murderer leave the room after killing someone? All indications indicate that the murderer seems to have quietly floated into the room, and after killing Hongmei, he has quietly drifted away, which is really a bit puzzling. ”

Yu Chengen said in surprise: "Could it be that there are really ghosts killing people?" Hongmei actually died at the hands of ghosts? Is this impossible? How can there be ghosts in the world? ”

"Naturally, there will be no ghosts in this world, but there must be people who pretend to be ghosts." Li Canghai took a sip of tea and muttered: "Although the room is messy, there is no sign of a fight, which shows that the murderer is very likely to be a person who is familiar with the deceased. ”

Conan nodded and pondered, "Judging from the situation on the scene, it is true. What is puzzling is how did the murderer leave after the killing? ”

"The doors and windows are closed, there are no signs of destruction, and the murderer seems to have evaporated out of thin air, which is really incredible." Yu Chengen frowned, knocked on the table with his hand, and after a while, he suddenly said: "Ah, I thought of a question, since the door is locked from the inside, why can't you see the key?" ”

"Keys?" Li Canghai and Conan glanced at each other.

"Brother Conan, did you find the key at the scene of the crime?"

Conan's eyes lit up and he said, "I checked the room and didn't find the key. ”

Li Canghai pondered for a moment and pondered: "Since the door is locked from the inside, the key must still be on the scene." But there is one more thing that may be crucial to this case. ”

Conan nodded and said, "I know what Brother Li said, just leave this matter to me to investigate." ”

"Brother Li, Brother Nan, what are you talking about?" Yu Chengen was confused by what the two said, and asked confusedly.

The two looked at each other and smiled, and Li Canghai said: "The secret of heaven must not be revealed, and you will know when the time comes." ”

Conan looked up at Nikko and nodded, "Since that's the case, then I'll investigate first." ”

After Conan left, Yu Chengen pushed Li Canghai towards the scene of the crime.

When he came to the scene of the crime again, Li Canghai found that several women in Lan Yue were burning paper money in front of the door, and several women looked pious and kept bowing to the four corners of the room.

Seeing Li Canghai coming, after Lan Yue and the others saluted Li Canghai, they said: "Immortal Chief, don't blame, we have no intention of destroying the scene, but Hongmei has an accident. ”

Li Canghai looked at them, nodded and said, "It's okay, this is your intention, not to mention that you didn't enter the scene and didn't cause damage to the scene." (To be continued.) )
