The library's business hours ended in a blink of an eye, and Officer Twilight and other passers-by departed.

The original staff of the library were also very able to understand the principle of Ke Xue, and they said that they would never work overtime like the missing Yutian, and quickly packed up their things to go home in their respective posts.

Only Toru Amamiya took Kotoko Iwanaga around the library under the guise of continuing the investigation, walking around the library, picking out a few books to browse from time to time, looking like he was going to delay until the end of work.

Conan and a few children have long since disappeared, and Director Tsugawa didn't pay too much attention to the children who just looked a little smart.

He tiptoed behind Toru Amamiya, only to be alertly spotted by Toru Amamiya.

"What's wrong? Mr. Curator? ”

Seeing that Toru Amamiya was so alert, although Director Tsugawa was a little surprised by this guy's acuity, he was not too panicked, because he didn't bring a guy this time.

"Nothing serious...... It's just that it's almost time for our library to close, aren't you two leaving? ”

Director Tsukawa said with a somewhat wry, "Oh, I'm glad you love books, but I'm sorry you had to leave."

"There's no hurry."

Toru Amamiya replied nonchalantly, casually flipping through the books in his hand, and Kotoko Iwanaga on the side was also very well-behaved, tiptoeing over to see Toru Amamiya.

"We have a clue about Mr. Tamada's disappearance that needs to be investigated, so we may have to stay in the library for a while."

"But the library's closing time is approaching...... When the time comes, it won't be good if you put the two of you in the library, Mr. and Miss. ”

Director Tsugawa said apologetically, a little wary in his heart.

The detective, who seemed to have been in the newspapers, kept looking at himself with very strange eyes while the police were still around, as if he had noticed something.

Damn, if it weren't for the sudden request of the relevant departments to close the museum and carry out some major inspection activities yesterday, I would have moved the body elsewhere a long time ago.

Unlike now, when you have to be scared here, Director Tsugawa is very bored with these two detectives, and tries to find an excuse to send these two detectives who are in the way away.

But unexpectedly, as soon as he made a normal excuse, he saw Iwanaga Kotoko take out a string of familiar keys from his satchel.

That's the key to the library door.

Although he is a dog, he is a big dog who has transformed the library he manages into a base for the trade of goods.

Director Tsukawa should have always wanted to do a good job of protecting his lair to prevent his secret from being discovered by outsiders.

But unfortunately, although Director Tsukawa has always wanted to strengthen management, the Rice Flower Library, as a public library, is not his word.

Many of the desired management measures could not be implemented by Director Tsukawa.

It is precisely because of this that the day before yesterday there was an unexpected incident such as that damn guy in Yutian accidentally discovering his secret.

And things like the door key, although he has always kept it very carefully under his interference.

However, some librarians who need to open and close the library on a rotating basis have always kept it in their hands.

What kind of uninteresting guy handed over this kind of thing?

Director Tsugawa cursed in his heart, and vowed to find an opportunity to pick and pick on the original owner of this key the next day.

But complaining is complaining, and the director of Tsugawa on the surface is still that amiable.

He bent down slightly, trying to keep his head at the same level as Kotoko Iwanaga as a sign of respect.

"Excuse me, ...... is this key?"

"It was given to me by Mr. Mikazuki, and it was he who commissioned us to investigate the disappearance of Mr. Tamada......"

"So, I don't bother Director Tsukawa, after we finish our investigation, we will clean up the library, lock the door and leave."

Kotoko Iwanaga replied obediently and demolished Director Tsugawa, but my last way to retreat.

Damn, that's the only way to get rid of both of you.

Director Tsukawa gritted his teeth secretly, he knew that the disappearance of several people in the library in succession would definitely attract more attention from the police.

The fact that he was hiding items in the library is also more likely to be exposed because of this.

This is also the reason why Director Tsugawa did not make up his mind to kill people at the first moment when he noticed that Toru Amamiya seemed to have found clues that were unfavorable to him.

But since these two people are so ignorant and refuse to leave even if they are persuaded by their own words, then don't blame yourself for being a killer! Director Tsugawa was ruthless in his heart.

"Then, I'll investigate with the two of you here and look for clues."

His face remained unchanged and he made a request to join the two of them in the library to find clues.

"After all, as a librarian, I am familiar enough with the inside of the library, so I should be able to provide a little help to the two of you."

"Besides, it's disrespectful to leave by yourself and let guests browse books alone, isn't it?"

Toru Amamiya nodded, he couldn't ask for this.

Deliberately staying in the library all the time, and even finding a tanuki spirit to borrow the key to the library for this purpose, Amamiya Toru certainly has some ideas.

Director Tsugawa, as a worm who had just killed someone and hadn't even had time to transfer the corpse, certainly couldn't let Toru Amamiya and Kotoko Iwanaga investigate in the library at will.

And Toru Amamiya also hopes that Director Tsugawa can show his feet as soon as possible, lest he have to look everywhere for evidence of his drug use and his death of Kazuo Tamada.

Torture is also a compulsory subject for dark organizations......

What's more, what better place to educate than a dark library?

-------------------------------------

As the others except Toru Amamiya and the others left one after another, the toilet that should have been empty, four little heads stretched out.

"That's it! It's all gone. ”

"Conan, what are we going to do now?"

A few imps whispered in the uninhabited toilet, and finally looked at Conan.

Really, I told you to go back, but you refused to leave...... Conan grumbled inwardly.

"I'm looking for a corpse!"

Conan said helplessly, causing a burst of "huh~" from the imps behind him.

"But when the police came to investigate just now, didn't they find nothing?"

I don't know what I'm staying for, but the children who stayed because Conan wanted to stay are using their curiosity and asking questions.

"I always feel a smell in the library......"

Conan touched his chin, didn't pay too much attention to the children's questions, put on his classic thinking style, and reviewed everything he encountered today.

The police hadn't paid attention before they came, but when they came, as if some kind of magic switch had been activated, Conan quickly noticed something unusual in the library that he hadn't noticed before.

It was a strange smell.

Conan quickly judged it with his nose, which he had trained professionally in Hawaii and had been honed thousands of times in actual combat.

The stench was none other than the stench of corpses common at the scene of the crime.

And Conan can also see that Toru Amamiya also seems to have noticed something, but Toru Amamiya did not take the initiative to partner with Conan, and Conan did not find a good time to get rid of the young detective group and team up with the high-level Toru Amamiya.

Oh, it seems that Toru Amamiya doesn't know that he is Shinichi Kudo......

So I had to start exploring alone with tears in my eyes.

Hmph, but this is also a rare opportunity, this time I must surpass Toru Amamiya, Conan thought to himself.

He quietly poked his head out of the toilet.

The last rays of the sun were like blood, spilling diagonally on the floor of the library.

A figure resembling a little black stood under the blood-drenched sun, and the thick dark aura on his body almost drowned Conan.

Conan:!
