In the evening, Takagi and Shiratori are called by Officer Twilight to Shinagawa to hunt down a long-haired man suspected of being an arson suspect, leaving Sato to continue to investigate the fire.

Gao Cheng followed Sato to find the place where Ayumi saw a suspicious character yesterday.

Several Kamen Superman toy machines, next to the alley, opposite the alley is exactly where the fire started, but unfortunately the surveillance in the nearby store can't shoot this, and there is no way to verify the arsonist that Ayumi said.

"If that guy continues to commit crimes, he should be setting fire somewhere today, right?"

Gao Cheng took the map and marked the scene of five consecutive fires.

The first was in Ikebukuro, then Asakusabashi, then Tabata, Shimokitazawa, and finally Yotsuya, where they investigated, but they were all near the station, so I really didn't see any connection......

"Still clueless?" Gray Yuan chuckled, "You, the great detective, are usually confused, so you shouldn't still be thinking about Officer Sato's promise?" ”

"It's not like I'm not the only one who can't think of it," Gao Cheng snorted and looked at Conan who was thinking on the other side, "Then again, don't you have a Prada purse yourself?" ”

"It's been last year."

"It's not broken......

Gao Cheng couldn't help muttering, this woman likes bags and the like, but she saves her salary every time, and now she is probably a small treasury.

Gray Yuan glared at Gao Cheng vigilantly, and took out a pen and paper to outline the location of the fire site: "Connected by lines, it's just an ordinary trapezoid, and there is no regularity......

Yuan Tai leaned over and said, "It looks a bit like a tadpole." ”

"It's more like a spoon, right?"

"Spoons?" Gao Cheng looked at the map again, "Whether it's a tadpole or a spoon, the order of setting fire is wrong, right?" It doesn't seem that the prisoners set the fire along the adjacent area, we are in the middle of the other places, and the third and fourth places are too far away, it is almost like graffiti on a map......"

"Graffiti?" Gray Yuan's expression changed slightly, and he snatched the map from Gao Cheng's hand.

Gao Cheng looked at the gray plain who suddenly fell into deep thought, paused, and asked Sato helplessly: "Officer Sato, Officer Takagi, have they caught the arson suspect?" ”

Sato took out his mobile phone and said, "I'll make a call and ask." ”

At Shinagawa Station, Takagi answered the phone: "We have arrested the escaped suspect at Shinagawa Station, but he keeps saying that he is not an arsonist, just a thief who broke into the empty door......"

"Thief?" Sato turned back to Gao Cheng and shook his head regretfully, "It seems that we have to find another way......"

"That's right, that, Officer Sato," Takagi whispered as he stole a glance at Shiratori and covered the phone, "I already know who the robber was eighteen years ago, and if my inference is correct, it may ...... Don't be shocked when you hear that, the robbers are probably among the few we saw this afternoon......"

Shiratori suddenly appeared beside Takagi with a calm face, and swallowed back Takagi's words, and said with a dry smile in a cold sweat: "What's the matter, Officer Shiratori?" It almost scared the hell out of me! ”

Shiratori looked at Takagi suspiciously: "Takagi, your actions are very suspicious, who are you calling?" ”

"Y-What are you talking about, it's really ......"

"Officer Takagi?" Sato shouted, but there was no response on the other side of the phone, and he said in a daze, "What is that guy Takagi doing?" Suddenly said that he knew the robbers of eighteen years ago, and he didn't speak......"

"Officer Takagi already knows?" Gao Cheng's ears moved, "Aren't they busy arresting arsonists?" How did you get to the case of 18 years ago? ”

Sato smiled bitterly: "I don't know ...... either"

"Officer Sato," Takagi's voice rang on the phone again, wheezing, as if running, "I understood all the puzzles from eighteen years ago......"

"What the hell are you doing, Takagi?" Sato urged, "If you know who the robber is, tell me quickly!" ”

"Hold, I'm sorry," Takagi leaned against the wall, relieving, "The robber should be ......"

"Bang!"

The sound stopped abruptly, there was only a crashing sound, and the phone seemed to fall to the ground.

"Takagi?" Sato's face turned slightly pale, "What's wrong?" Takagi! Talk back! ”

Gao Cheng watched Sato keep calling, but in the end there was only a busy sound.

"Someone hung up...... Did Officer Takagi have an accident?! ”

Seeing Sato anxiously calling Shiratori, Gao Cheng's heart sank slightly.

The arson case has not been investigated clearly, and even the old case from eighteen years ago has been pulled out, and it is very likely that Takagi was attacked by the robbers of the year......

However, this also shows that Takagi really knows the identity of the robber.

In the afternoon, four old friends of Sato's father went to the intersection to worship, and Takagi should have said that they were the same people......

"Officer Sato," Gao Cheng asked, "will your father's old friends be able to find their location?" ”

"Huh? They went to an izakaya to drink, it should be the Nanakuji izakaya in front of Shinagawa Station......" Sato held the phone, his face changed suddenly, and a trace of sweat flowed from the corners of his eyes.

"The murderer must be among them," Conan said solemnly, "One of those four people overheard Officer Takagi's speech, and it was likely that he wanted to kill him before attacking him." ”

"In Shinagawa...... "Shibara said coldly from behind, "the arsonist's next arson location is also near Shinagawa Station." ”

"Huh?"

Gao Cheng looked at Gray Yuan in a daze: "Xiao Ai, how do you know?" ”

"Graffiti," Gray Hara said, holding up the atlas and drawing lines with a marker, "The arsonist said that the night before the festival would be completed in one place, and some festivals would use fire, didn't they?" The arsonist was actually trying to write a big 'fire character' in Tokyo, and the last stroke landed at Shinagawa Station. ”

"The man who attacked Takagi ......"

"If the arsonist mistakenly thinks that Officer Takagi witnessed his arson and call the police, it is not impossible to attack Officer Takagi," Ashbara paused, looking in the direction of Shinagawa, "If this inference is correct, there may be a body found near the scene of the fire in the next place, just like in the fourth case." ”

Sato didn't care about the calm that Gray Plains didn't match his age, and the appearance of Takagi being killed appeared in his mind, and his face turned even paler: "I'll go to Shinagawa Station, Joto-kun, you can take them back first." ”

"Shall I take them back?" Gao Cheng turned around and looked at the obviously reluctant Ayumi, and said with a wry smile, "But my job is ......."

"Somebody has to take care of these kids, right?" Sato anxiously sat in the driver's seat, "Take them home by train, and meet at the main hall tomorrow......"

Gray Yuan interjected: "The gangster who attacked Officer Takagi is also likely to be an arsonist, shouldn't you bring Ayumi who is the only one who has witnessed the gangster?" ”

"This ......" looked at the gray plain who questioned like a little adult, Sato was stunned, and sweat flowed from his face.

Why are children so good now?

"Then let's all go together," Gao Cheng said with a funny smile, "I'll take care of them." ”
