Kindaichi Shounen no Jikenbo EP45 - Black Butterfly of Death Murder Case File 3

Miyama arrives at the balneary first and finds Ageha bleeding from stab wounds and there is another message from the killer. They discover through her blood type that 25 year old Ageha cannot be the daughter of both Shimon and Midori. Later that day, Shimon is killed and also hung on the wall like a butterfly. Hajime questions Yamano Katsunori about 25 years ago when his assistant was Minoru Suga and the wealthy Shimon Madarame provided funding for butterfly research. Minoru Suga suicided on the eve of the announcement of the discovery of the luminous butterflies. Hajime suspects those events and the current murders are linked. That night Miyama and Ageha attempt to leave together but are stopped by Officer Inokawa. Hajime explains that Miyama is not the murderer who is still among them.
