Ghost Passenger Ship Murder Case: File 1 - S2-E5
Other mistake: Everyone present in the scene reacts to Kenmochi popping the police inspector badge out of his jacket pocket. That includes the female crewmember who is peeking from the corner behind Kenmochi and that can't see it at all. (00:18:00)
Ghost Passenger Ship Murder Case: File 1 - S2-E5
Other mistake: When the two horrible guys harass her, Miyuki and Kenmochi are both drinking wine. Miyuki is underage, and while certainly not technically and materially impossible for someone underage to drink wine even with a police officer present, in pretty much every episode when there's a party it is made clear both in dialogues and visually that underage characters are not having alcohol. They drew the wrong type of glass. (00:08:45)

Ghost Passenger Ship Murder Case: File 1 - S2-E5
Continuity mistake: Kenmochi dumps two heavy bags on top of Kindaichi, then picks up two suitcases himself; a pink one in his right hand, a dark blue one in his left. When the second mate asks him the ticket, the two suitcases have swapped, and Kindaichi a moment later carries the heavy bags but also suitcases with the same colors as Kenmochi's, which he gave to the second mate...who is carrying a single suitcase, and grey. Later on, we see only those 2 bags and 2 colored suitcases, anything else vanished. (00:04:10)

Continuity mistake: At the dismal dinner party, Miyuki wears her hair in front of her right shoulder, except in the shot when the ocean magazine photographer introduces himself, when all of a sudden her hair is all the way back, and then after the captain throws his glance at the crowd in POV.
