"The second person who came to this room after Uncle Mori, I think it should be someone who knows Ritsuko Urubi, so that Ritsuko Urui will be strangled to death by the other party unsuspectingly, and the person who can do this, Aunt Fei Yingli and their companions who came with them may be more suspicious, plus this weird door chain, my initial suspicion is that Mr. Saku, who has left this hotel with Uncle Maori!"

"What? You say the murderer could be Mr. Hoshi Saku? How so? He just looked very enthusiastic! ”

Hearing Yuichi's answer, Yamamura Cao immediately became a little unacceptable.

And at this moment, on the other side, Conan, who was observing near the head of the bed, also had his own clues, staring at the note paper on the table next to him, and he also began his own reasoning with a light hand and flipping it.

"The note on the table has been torn off, and it shouldn't have been a long time ago to see the traces, was this note torn by Ui Bing Ritsuko, or was it torn by the murderer? But no matter who tore it, there must be some information related to Usui Bing Ritsuko recorded on this torn note, if you want to find this note, maybe you can look for it there! ”

Conan, who thought of it, immediately jumped off the chair next to the bedside table and rummaged through a trash can not far away, and strangely enough, he actually found the note in the trash can.

"This note is crumpled and messy, but looking at the torn marks on it, it can probably match the traces on the convenience book, so what is written on this note?"

"Huh? Lin 2? What does that mean? ”

Looking at the post-it note in his hand, Conan pondered alone, but what he didn't realize was that Fei Yingli, who was trying to figure out the suspicion of the telephone line, also came to the bedside table, looked at the note in his hand, and suddenly snatched it up, and analyzed it suspiciously.

"Is this Ubiki's handwriting? Does this Lin refer to the lawyer Lin who worked with her this time? ”

"Lawyer Lin?"

Hearing what Concubine Yingli said, Conan immediately asked suspiciously.

"That's right! Lawyer Lin! Because he told me before that he wanted to contact Ui Bing to discuss the case they were responsible for, he ......"

"The case? What case? ”

"It's a hot lawsuit about factory wastewater! Originally, I was approached by lawyer Shiozawa, but we were not interested in this case, and lawyer Saku's specialty was criminal cases, so in the end, lawyers Usui and lawyers Mikasa were in charge! However, in the first instance, because of Mikasa, he actually lost the case. In order to win in the end, Usui asked me to introduce someone else to replace Lawyer Mikasa, so I plan to introduce my friend Lawyer Lin to her, but I haven't told her about Lawyer Lin yet! How did she know about Lawyer Lin? ”

"Besides, we shouldn't have told Lawyer Lin about staying in this hotel, so how did he know where we were?"

"He said he heard about it from Lawyer Shiozawa!"

Just when Fei Yingli was muttering alone about the note with Lin written on it, the waiter who came in at an unknown time heard her inquiry and immediately answered.

"Huh? How do you know? Also, why did you trespass in? This is the scene of the crime, and idlers are forbidden to enter! ”

After Fei Yingli, who was startled by the sudden opening, shook it, and after seeing who the person who answered the call was, she immediately reprimanded her with some annoyance.

"Ahh I'm sorry! I'm scared of you, ma'am! I suddenly thought of a strange thing, so I came up to tell Mr. Detective! As for why I know, it's because I'm the one who took Lawyer Lin's phone into this room! ”

"Huh? It's true? And by weird things? ”

Hearing what the waiter who had just put in by himself said this, Yuichi immediately asked.

"Oh! That is true! In fact, Mr. Lin called twice, the first time he was connected, the second time he didn't, so I went to this room to see what was going on, which means that I came here twice in total. ”

"Twice?"

"Hmmm! The first time, I rang the doorbell and no one answered the door. Then I went back and told Mr. Lin that the tenant must be resting, but Mr. Lin said that the matter was very urgent, and maybe the tenant was taking a shower, so I asked me to go and see it again, but when I came back, I saw a Do Not Disturb sign hanging on the door of this room, and a note was posted on the side of the sign. ”

"Note?"

"Hmmm! I remember the note saying, sorry! Please help me convey it, and I will definitely pay the money! And the words on the note are also written crookedly! ”

"Did you convey this message to Lawyer Lin?"

"Of course I did! However, Lawyer Lin was very puzzled and said that he just wanted to tell the tenant of this room that the appointment at two o'clock tomorrow would be changed to four o'clock! He doesn't understand what kind of money this is! ”

"Oh? Did Lawyer Lin make an appointment with Ritsuko Usui at 2 p.m. tomorrow on the first phone call? Then the Lin 2 written by Ritsuko Ui Bing can be understood, but the second time Lawyer Lin suddenly changed the appointed time, the note she posted again was strange, and it felt a little incompatible! Why is that? Is this some kind of code? ”

Yuyi, who heard the waiter's explanation, took the note in Fei Yingli's hand, glanced at it himself, and then muttered to himself with a thoughtful face.

"Cipher? You were filming a spy war drama at the time? It's just the first time that U Bing and Lawyer Lin have dealt with each other, how can they agree on any code? ”

"That's the problem with the person who posted the note! That's right! Mr. Waiter, come here! Do you look at that strange note you saw, the same handwriting as the one written on this piece of paper? ”

After hearing Concubine Yingli's denial, Youyi ruled out this possibility, and immediately boldly thought of another possibility.

And after taking the note he handed over, the waiter shook his head and denied it as he expected.

"That handwriting is completely different from the handwriting on this post-it note!"

"Is it completely different? So if the person who wrote this post-it note is not Ritsuko Usui, and the waiter is in this room when he comes here, what would make him post such a post-it note? ”

Following this line of thought, Yuichi gradually noticed the convenience book on the bedside table, where there was a menu of this hotel randomly placed.

And Yuichi, who saw the menu, finally showed a triumphant smile, he could already be sure that the murderer was that person, and now all he was looking for was evidence.

However, just as he was sure of what he was thinking, a policeman knocked on the door of the room and walked in.

"Officer Yamamura! The test results are in! And we got an important clue! ”
