Yoko had returned to Conan, hand in her pockets. The detective was towards the police.
-Ah, the kid with glasses is back! Sonoko remarked as she approached the girl. Have you seen Ran?
-Have you? Erm... Not really...
I haven't seen her since I went to see Takagi haha...
-How's the investigation going? asked the brunette with glasses.
-It doesn't seem to be going anywhere... sighed the rich kid, looking a little jaded.
-But Cool Kid seems to have understood something! added Jodie.
She's carrying on with her "Cool Kid...".

Megure walked past the group, on the phone. He quickly hung up, so none of the three girls could tell. It was the blonde who decided to find out the situation from the inspector.
-So what's going on?
-Erm... The victim is a director of an intelligence agency and it's very likely that the person he was investigating, suspected of embezzlement, is linked to his murder. So I contacted his agency... I thought that someone might know the name of the person he was suspicious of...
-So? asked Sonoko.
-Didn't he? No... His client had asked him to investigate in the greatest secrecy and he hadn't told anyone about the results...

-And there's no way of finding any information? Like in a file or something? Yoko tried.
-No, there isn't. We still have his computer but we need a password to access it... Nobody knows it...
-A password? Reflected the schoolgirl with the chestnut hair. Of course! What if the symbols we found were that password?
-That's what I thought too, and earlier I asked one of the employees to type it in, but nothing came of it...
-I don't see why you have to go to such lengths to enter the name... Maybe, like the square trick, we're missing another part... sighed Yoko.
-Why would we be missing a part? asked the rich girl abruptly.
-I'm just saying one possible thing...

The young girl couldn't help looking quickly at the English teacher. She seemed more focused on the case.
I mustn't forget to keep an eye on her...
-If these acronyms really are the murderer's name, it's Chiba-keiji we need to keep an eye on. interrupted Conan.
I need to keep an eye on him too...
The young boy had written the ideogram for "Chi", 千, on a notebook and hid a part of it, resulting in a cross. If you hid the bottom of the cross, you'd get a triangle. The detective did the same thing with "Taka", 高, where by hiding more than half, you could see a square or a round.
-I agree about the square, but I can't see a circle! grumbled Sonoko.

-Well, Sonoko-neechan, you know there are lots of people who make a circle instead of a square to save time! explained the young detective. Agasa-hakase always tells me: 'When you're in a hurry, you have no choice but to use abbreviations!

The policeman seemed to have a revelation at the boy's words. The former schoolgirl turned her head as she heard him unfold a piece of paper. The list of suspects. She ignored Sonoko answering Conan and went behind Megure, jumping up to see the sheet. But she didn't need to continue.
-Kuniyoshi Bunta! It's him! cried the man.
No one understood how he had found the suspect's name, so he took the time to explain. The name was spelt 国吉文太. The square was therefore the 国, not complete to go faster. Then, by hiding the upper parts of the three other Kanji, we obtained the round 吉 instead of the rectangle because of the writing speed, the cross with 文 and the triangle with 太.

After this quick explanation, Megure went off to arrest the suspect.
And Conan left with him...
No one had really noticed her absence, but they soon would.
-Ah, it's so late already... It's taking her a long time to come back, Mouri-san... Jodie remarked.
-Maybe she's on the phone asking Shinichi-kun what the 'X' means! Sonoko surmised.
Or maybe she's lost...

Just then, the person concerned arrived.
-I asked Takagi-keiji! In any case, even if Shinichi heard himself say 'I'll give you my precious 'X'', I doubt he'd be able to answer.
I can confirm that...
Yoko almost laughed. If she wanted to, she could tell her brother what it meant.
Well... I didn't even think to look to see if Akahara had already used that thing...
She turned, walked away and took out her phone. She searched her messages for her adoptive mother's number and pulled up my conversation.
She never used it with me haha... Maybe with Asahi... I'll ask her one day...
The kid in glasses put her phone away. At the same time, Conan returned from the case. It was solved.
