The Hong Kong Kowloon Treasure Murder Case File 1 - S1-E1
Plot hole: The plot of the four-parter is complete nonsense even for a kid show. It is tied together by unbelievable pure coincidences; Miyuki is the perfect doppelganger of a missing model, Kindaichi randomly bumps into a high school mate who just happened to be in HK as well (!), and they both equally randomly (so they think) bump into the model who was just chilling on a park bench (so much for disappearing!), he befriends the son of the victim from 20 years before.
