Kindaichi Shounen no Jikenbo EP62 - Graveyard Island Murder Case File 3

Hajime deduces the murderer is Tatsuyuki Hiyama who killed Yonemura's team and captured Yonemura to appear as a Ghost Soldier. However, the killer did not realize that Yonemura scratched a dying message while he was tied up, which was a type of Morse code that referred to an event in a village 2 years ago. Hajime proposes that Hiyama then killed him with poisoned bread and that the murderer has an accomplice within the group, and he accuses Remi Morishita. However Hiyama denies knowing her and eats a poison capsule, intending to take all the blame himself. Later, Yonemura's poisoned body is found, dressed in a Japanese soldier's uniform confirming Hajime's hypothesis. Remi Morishita, eventually admits her guilt and is imprisoned, but after she discovers that she is pregnant with Hiyama's child, she tells Hajime their story. She and Hiyama were from a small mountain village which was burned down 2 years ago by young men playing war games and only a few people survived. They moved to Tokyo and overheard Hagimoto and the others talking about how they caused the fire. Hiyama swore to take revenge for the village and their parents' deaths.
