The final case of the Kagi no Kakatta Heya (鍵のかかった部屋) series is a two-parter called “The Glass Hammer.” I think at the end of the review for episode nine, I gave the impression that this would be the last episode, but I’m delighted to say that there will be an episode 11.

Kagi no Kakatta Heya Title

Unlike all the episodes so far, this one does not begin with our security expert/detective Enomoto Kei (Ohno Satoshi) outlining the nature of the locked room. In fact, no murder has occurred when Serizawa (Sato Koichi) brings Enomoto into the situation. In this case, Serizawa is working for a company that is about to go public – that is, issue publicly traded shares on a stock exchange. You might have heard that Facebook recently did the same thing to rather unfortunate results (the value of the company is still twenty percent below its initial value), so it’s an extremely tense time for a company and there’s a lot of pressure to get things right. There’s also a lot of legal trouble involved.

It’s pretty clear that tensions are high in this company, but that’s understandable. What isn’t so clear is why there’s a bullet hole in the president’s office, and why the company and its president have been receiving threatening mail.

Bullet Hole in the Office

Clearly, more security is called for, and since Serizawa is already involved, he naturally suggests . . . well, you know:

There's This Guy I KnowEnomoto

We get a lot of scenes detailing the particular tensions on the executive floor, with the president, vice president, director, project leaders, the president’s secretary, and others all on edge. In particular, there’s disagreement about which to prioritize – a robot nanny project or a monkey helper project. So, plenty of potential suspects, though the avid drama viewer has to be be especially suspicious of the vice president:

The Vice President

The actor is Suzuki Kazuma (鈴木一真) and I recognize him from Mr. Brain and Tantei Gakuen Q, though he’s been in plenty of other dramas. But I instinctively put him on the “bad guy” side of the spectrum – maybe because of his past roles, but also possibly because of the sneaky smile he sometimes has. We’ll see if he plays to type, or if the casting director is toying with our expectations.

Before Enomoto can begin securing the executive floor, the secretary gets word from a security guard that a window cleaner had noticed that the company president had collapsed in his office.

Just then, Enomoto arrives for his appointment to begin his work – a bit too late.

Enomoto Arrives Too Late

The cause of death was a blow to the head, but a weak blow, and the vice president tells us that someone else might not have died from the blow, and that the president was susceptible because of a recent surgery. This doesn’t narrow down the suspects, since apparently everyone knew about the surgery.

Weak Blow to the Head

As the police detective on the case explains, since no one entered or left the floor from when the president went into his office and when his body was discovered, it can be considered a locked room case.

Declared a Locked Room Case

I don’t know about you, but I prefer to have Enomoto declare it, but we’re doing things a bit differently in this case. After the police detective makes the statement, we get this line-up of the suspects:

The Suspects

I’m not going to get into the case details any further, since the process of discovery’s part of the fun. Since this is a two episode case, it’s safe to say that the process will be full of surprises.

For instance, who’s the person in these sneakers?

What about Serizawa’s theory that a monkey did it?

And his theory that a robot did it?

Will Serizawa’s legal responsibility to the company prevent him from investigating the case at all?

Serizawa Juggling Responsibilities

Since the case doesn’t end with this episode, I can’t say too much about the actual mystery. There were plenty of clues, and it certainly had you guessing throughout the show, but without the resolution, we have to wait until next week to see how good it really is.

It was a riveting hour, though, and the cliffhanger, while pretty much as-expected, was still very satisfying. I’ve said for a long time that we need to find out more about Enomoto’s background. Well, it seems like they were stringing me along all the way and they’re finally going to deliver. I’m not saying we’ll get a full dossier, but anything is better than the nothing we have right now.

If you haven’t seen the episode yet, get ready for some serious twists. It looks like episode 11’s going to have a lot of explaining to do.
