So, we come to the conclusion of Kagi no Kakatta Heya (鍵のかかった部屋). This episode resolves the case the previous episode introduced, so if you haven’t seen episode 10 already, be aware that this review will contain spoilers from that episode, pretty much right away. As far as the contents of this episode go, though, I won’t give away anything that occurs in the latter part, and in particular nothing that leads directly to the case’s conclusion.

Opening to the Final EpisodeOpening to the Final Episode 2

At the end of episode 10, Enomoto (Ohno Satoshi) was arrested on suspicion of committing the crime, because the victim – the president of Bay Leaf – accused had caused legal trouble for him years ago. The scene where he gets hauled away was a wonderful cliffhanger, and led us to wonder how Serizawa (Sato Koichi) and Aoto (Toda Erika) would get on without him.

He left them in this locked roomWhere is he now?

No dice, though. Right after they took a few minutes to detail what had happened in the case so far, Enomoto gets released. Since this is almost the first thing that happens in the episode, I hope you will forgive me for not considering it a spoiler. So much for the tension there, though, as Enomoto is back at in the lead in barely the blink of an eye.

Why was he so quickly released? Because the first suspect – the hapless manager Hisanaga – admitted to the crime. Of course, that pretty much guarantees that he didn’t do it, but we already knew that from the last episode.

Aoto Speaks to Hisanaga

Back on the job, Enomoto knows exactly who he wants to question first – the window cleaner who was looking at him so suspiciously as he was being arrested. Is there some history between them as well? In any case, the window cleaner was the first one to see the president dead, so it makes sense to question him.

Questioning the Window Cleaner

There’s a hostile feel between the two of them, and it becomes very apparent when Aoto leaves the room to take a cell phone call from Serizawa.

But if the window cleaner’s the culprit, how did he do it? After all, he was outside of the locked room, the windows don’t open, and there’s no way he could have entered or exited the executive floor unnoticed.

Aoto’s expressions when coming up with some theories of her own are worth a few screencaps.

Then there was Serizawa’s expression when he thought he had the answer.

He even gets accolades from Aoto . . .

. . . but no such luck when it comes time to test the idea.


I’ll leave the summary with that. This series has been as consistent as the expression on Enomoto’s face . . .

Enomoto's consistency

. . . so it should come as no surprise that this case hit the mark as well as any case in the season. However, we definitely did not get all the pieces to the puzzle through the two episodes, so the viewer could come very close to the answer, but was missing some details. I think we can forgive the writers for that, since it was a remarkably intricate crime.

The motive was unimpeachable, too. If that doesn’t lead a character to contemplate murder . . . well, you get the idea.

Did we really find out about Enomoto’s background? Well, nothing but an outline, but I had my suspicions confirmed, and that’s always satisfying. He was what he should have been, and all is right with the world.

To wrap up this series, there’s no question that it was entirely enjoyable viewing. My only gripe with it is that it really had no surprises. Everything about it was perfectly consistent – good acting, interesting methods of murder, and genuine puzzles for Enomoto to solve. After Aoto locking the vault and Serizawa’s rant in episode one, though, there was nothing to make me jump up and say “this is great!” Maybe . . . maybe it was so flawless that it was plain. Does that make sense?

Anyway, my deepest gratitude goes to the EarthBuri Team for providing subtitles almost like clockwork by Thursday. I didn’t catch  the release schedule early on, but once I did, I was lucky enough to write my reviews without having to dictionary assistance. Also, thanks to all providers of the raw files.
