The three children sighed inwardly at the same time, feeling very disappointed.
Just then, Tsuburaya Mitsuhiko suddenly spotted something.
He froze, pulled the other two aside, and lowered his voice. "There are footsteps over there. It sounds like someone's coming out!"
The three children skillfully found a hiding place and huddled down.
With their small—and fairly small—builds, they crouched inconspicuously in the corner like three mushrooms of varying heights, sizes, and shapes.
They had only just hidden themselves.
A burly man in a black suit and sunglasses walked out of the supposedly abandoned building.
He adjusted his sunglasses, looked around, then quickly turned right and disappeared from the trio's view.
The three children silently watched the Man in Black leave, then recalled his appearance and actions.
Though they had no evidence, a piece of information instinctively surfaced in their minds.
—He was a bad guy!
...Mainly because he looked exactly like one.
And he was hiding in such a suspicious building.
The three gathered together and whispered, "Could he be one of those bad guys with guns by the river that day?"
When they had gone fishing by the river earlier, only Conan had directly seen Yamabe Koichi and the Men in Black on the rooftop across the river.
But when the children had asked Conan what was wrong, the detective, ever eager to answer questions, had spared no details in describing what he saw, along with his speculation that the shooter had been held hostage.
Now, combining what they already knew with all the information they had later stubbornly pried out of Haibara Ai, the three children eagerly made a connection.
—Maybe the people the police, Jiang Xia, and Conan had been looking for were hiding in this building.
"We need to tell them quickly..." Yoshida Ayumi
