Episode 767 sees Dr. Agasa taking the Detective Boys to the Ice Room boarding house, which is located in the mountains. There’s quite a bit of snow, and the kids have fun playing in it. Of course, there’s no such thing as a simple vacation whenever Conan’s around, and this excursion is no exception.

Three sisters own the boarding house, and two of them disapprove of the youngest sister’s boyfriend. The youngest sister is sickly and needs medicine, and when she discovers her medication is missing, her boyfriend offers to go to the hospital to get it while there’s a heavy amount of snow falling. When Masahiko, the boyfriend, never arrives at the hospital, Conan, Dr. Agasa, and the two older sisters go looking for him. They find Masahiko, and it appears he slipped down the side of a road to his death.

The police are unable to arrive due to the snow, so it’s up to Conan to gather the clues and put everything together to determine that this was a murder and not simply an accident. Not only that, he has to determine who the murderer is.

This murder mystery is resolved in one episode, which is more on the unusual side for Case Closed. There was an “interesting” clue that was involved in cracking the case, but the explanation for this interesting clue and how it came to be involved made sense. The culprit ended up being one of the last people I expected. However, when the motive was explained, it also made sense that this particular character committed the crime.

This was a decent murder mystery, although the idea of the crime taking place in snowy mountains isn’t new. But the way the actual murder was set up and executed is unique to this story, so I have to give some credit to this mystery.

And it’s been interesting to notice that Kogoro hasn’t been as involved with the mysteries in more recent episodes. Since the Winter 2015 simulcast season started, the cases have either involved Conan getting involved on his own, or Dr. Agasa is the adult around. It’s also been interesting to note that the Detective Boys have shown up in every episode that’s aired during this simulcast season. Ran has also had very minimal screen time in the Winter 2015 episodes so far. I wonder if this trend will continue, and if so, for how long.

From the preview for the next episode, it looks like Ai is going to be playing a major part. So major, in fact, that the mystery will be about her. I’m very interested in seeing how this story with Ai is executed.
