The murder gets more interesting this week…as I’ve said before, locked room murders tend to be hard to pull off, so we’ll see where things go. So far, I’m entertaining the same theory I had at the start of the series: that Magata Shiki has been dead long before Moe and Souhei ever got to the island and the person Moe was chatting with was a fake. The video chats seem too convenient as evidence and they could be easily faked, so I think they’re the weak link in the scenario.
However, the fact that the director was murdered must mean that the murderer is still on the island. If the murderer was in the room when door was unlocked, then I don’t see any other way to exit unless the murderer was hiding in the cart under the dress. Hopefully they don’t do something cheap like “the murderer hacked the camera feed”, but Souhei’s comment about the OS being programmed specifically to run into an error seems pretty worrisome. Also, these weird scenes at the end of the episode showing Magata with some unknown man must be relevant as well. What role does this man play in the murders?
