KEYS

No other students entered on the High School that day. All the surroundings were a field of police cars. In addition, everybody was sent back to their respective houses as soon as they approached the building.

The only students who were left in the high were Nezumi and Irina. After the arrival of the policemen, Irina started to recover her calm, but even though the research was going to be long and complex, they wouldn't be able to leave the scenery, that was one of the againsts of being the one who found the corpse and the only witnesses known at that moment.

But something was troubling Nezumi while she was thinking on how they saw the scene for the first time. She was unsure about what it was, but extremetly sure that it had to be something with the case.

"Hello, girls. My name is Albert Sinenoc. I'm the inspector from the police office."

"Hi..." whispered Irina in a lowed and sick voice.

"This is Irina Clemence and I'm Jane Seaside. How is the research going?" asked Nezumi.

"Well... We're doing what we can. I would really appreciate your collaboration... You are the only witnesses we know."

"I'd like my friend to be left aside. She was the one who discovered the... Well... The man... And she is a bit dizzy now."

"I see. So, Jane... Would you mind coming with me for responding a couple of questions?"

Nezumi followed Mr. Albert while Irina was looking at her with her pale face that was about to start crying again. They entered a room -a special room where the bad boys were usually punished during the breaks for their bad behaviour. It was little, about a quarter of the space a normal classroom would have, with a big table on the middle surrounded by six or seven chairs. The walls, and the furniture were all signed up with pen and markers, filled with all the naughty thoughts of the ones who had ever been trapped there- where Mr. Albert and a policewoman were about to take statement of her testimony.

The policewoman had a netbook in front of her, and was sitting in the other side of the room. Jane was feeling nervous and exposed, all that she needed was to think deeper on what was wrong on the crime scene.

Maybe there was something missing? Something that should not be there?

"Don't be nervous. You are not being suspected of anything."

"I'm not nervous" lied Jane "but... What was the cause of the death?"

"We are not allowed to give you that kind of information" said the policewoman severely "just listen and answer, it's simple."

"Okay, Miss" She said uneasy.

They asked her why they were coming so early in the morning, as they were supposed to be there at eight thirty instead of at eight o'clock. She answered that Irina, her friend, was the class' representative and they were going to tidy up the classroom before the classes got started.

After a while, Albert asked Jane whether she knew the victim, and she saw the chance of looking at the crime scene to determine what was wrong with it. She indeed knew the victim, as he was a teacher of the science department, but she just answered "I need to have a close look to the victim... Because I didn't looked directly..."

Albert saw a weird performance on Jane's behaviour. He didn't wanted to ask directly in front of his pals, as he didn't had any suspicion on her, but... She was too curious. A normal teenage in her sittuation would be less motivated or even shocked, as it happened with Irina, but...

Why was Jane acting so... Naturally?

Jane approached the dead body with Mr. Albert, and she looked everywhere, but no matter how much she tried; she didn't find any suspicious object.

She just saw on the body the marks of being stabbed.

"So... Bloody" she shivered.

"Do you recognize him?" asked another policeman.

"Yes... It's a teacher here..."

She got out of the room as soon as she could when she stumbled and fell on the floor, just when she was crossing the door. She hurted her knee and looked behind herself to see what was the stupid thing that made her fell down. She saw that one of the tiles was broken and loose.

"Are you okay?" asked Irina, when she got to the place where her friend fell.

"Hm... Yep. Irina... When did that tile got broken?"

"Huh? This is weird... I haven't see that before!"

"So... Interesting!" assured Nezumi before standing up.

Sinenoc heard the opinion of the young girl and felt even more curious about her. She was looking not only natural, but also interested on the research.

He decided to ask her something in a non-official way, to guess what the girl founded.

But when he was walking to her, she jumped and hooked the top of the door and kept hanged there for a while. Every single policeman was looking at her upset and Albert Sinenoc felt embarrased.

"Jane, get down here in this very moment." ordered the inspector.

"Sorry, Mister Albert" answered the girl and she found herself again with the feet on the floor "I was just..."

"You must not behave like that. Understood? Leave this all in our hands." he said seriously.

Jane and Irina sat down on the chairs that were left on the corridor by the police officers. Jane wanted to knew who the suspects were.

"Albert" said someone running into the crime scene "with other testimonies, we've reached a conclusion..."

"What conclusion?" asked Sinenoc.

"This is a closed door crime scene. It's an impossible scene! The only key of this classroom is now in hands of that girl over there!"

Irina took my hand nervously. She trembled for a second, probably specting that she would be accused of something.

"It's okay" whispered Nezumi "I know that you are innocent."

"But the key has always been with that girl?" asked Albert looking straight at the two girls.

"Apparently not... It's usually on a strong box at the head of studies' department."

"Hmmm... Has the strong box been forced?"

"No, and the keys of the strong box are always carried by the concierge..."

"Why do you say it is an impossible scene, then?"

"The department is locked too. There are no signs of have being forced... And the key of the department... Is always with the Director of School."

Everyone got shocked. Someone needed two different keys to obtain the key that would open the classroom, two different keys that were held by different persons. As the officer said, it was impossible for a single man to commit the crime, but Nezumi knew it was a possible crime scene, and not a difficult one if it was well prepared.

And this one was prepared indeed.
