File 1,052: Clumsiness and Suspicions
The deceased man who looks like Umisuke Hatoyama, but whose face is more wrinkled, is probably the older brother. Kobayashi looks at his face and confirms the corpse is that of Ginsuke, the owner of the farm. She only talked with him the phone, but after doing some research on the net, she knew his face—Umisuke's claim of being a younger brother was not a lie.
Kazami judges that it's been around 30 hours since the excavation bombs were stolen in large amounts from a construction site, and that there is now a risk of a terrorist attack. Amuro suggested that they make a move only after getting more conclusive evidence, but Kazami decided on his own to follow the steps of the suspicious worker Umisuke, and upon arriving at the ranch, he had the tables turned on him.
Kazami was thinking that Umisuke killed Gisuke, but Conan and Amuro realize that Gisuke killed himself in this room from the corpse and the scene's conditions—Umisuke, who came after, merely laid Gisuke's corpse on the bed. As for the motive, from the marks left by the corpse's highlighter pen, they think that he was investigating something. However, they couldn't find a yellow highlighter among the pen he supposedly used.
Conan uses the detective badge to contact Haibara, Genta and Wakasa, and tell them about their own situation. As he tells them that Umisuke has bombs, so they shouldn't act carelessly. Umisuke appears, and Haibara realizes who he is—she stops and deceives Genta, who didn't realize and was going to reveal their identities by saying that he is a friend of Conan. Just then, Hitsuka and Nanbu appear, they wanted to ask various things to Gisuke because they're not familiar with the ranch, but he wasn't there. Umisuke lies by saying his older brother is away because he's hospitalized. It looks like the thing Hitsuka and co. are setting their sights on is in some place in the mountains, so they don't know where it went. Umisuke, Hitsuka, Nanbu gather with Kanō and decide to search for it together.
Conan tells them to look for a chance to contact the police while Umisuke is away. Haibara's smartphone is out of battery and Genta left his at home, but Wakasa brings out her smartphone from her backpocket. However, as she tries to contact them, she notices that the Shogi piece is gone and loses her composure. When Genta tells her that Amuro picked something, Wakasa becomes discouraged, and drops her smartphone in a bucket, submerged it in water—their only means of contacting the police is gone. Meanwhile, Kanō tries to find the place while watching the footage of his smartphone, but becomes impatient because he can't find it. Conan learns from Mitsuhiko what kind of footage Kanō was watching.
As Kazami looks at the shogi piece Amuro's holding, he casually starts gossiping about how Haneda Shukichi maintained his Six-Crowns by defending himself in one of the title matches. Amuro remembers during their conversation that he saw the Kōji case files during his Security Police training. This shogi piece was a good luck charm—the only personal belonging of Kōji's that went missing. The piece was something he'd earned after beating his master in a shogi tournament for the first time. Looking closely at piece, it is clear that it was stabbed. Recalling the Haneda family's conviction that the piece—something he'd never let go of—must now be in the hands of the culprit, Amuro starts to think that the one who killed Koji Haneda is at this very farm.
Meanwhile, Haibara and the others try to go back inside the ranch, but they can't even go in from the back door—it's locked. At this moment, Wakasa pretends that there's broken glass on what she tripped on and makes it so they can go in. Conan hears about the kidnapping from Ayumi who woke up, and realizes the goal of Kanō, Hitsuka and Nanbu from all the information he's gathered.
