The Locked Room Murders or Kagi no Kakatta Heya or 鍵のかかった部屋 (2012) Episodes 3 and 4
The third episode of The Locked Room Murders or Kagi no Kakatta Heya or 鍵のかかった部屋 (2012) sees a body found with a single stab wound to the back in a hotel bedroom which had a chain put in place from the inside. This makes a change because, from the outset, this is treated as a murder investigation. For all practical purposes, it’s impossible for the chain to be lifted into place from outside. Yet, if the killer was inside to put the chain in place, how did he or she get out? We are into the land of the elite Shogi players. As our entry into the story, Gou Serizawa (Koichi Sato) is general counsel to the National Association and fielded a call from the deceased, one of the senior professionals, just before he was found stabbed to death in his hotel room. The police begin harassing our lawyer who refuses to reveal anything of what was said. Because he finds this embarrassing, he sends Junko Aoto (Erika Toda) and Kei Enomoto (Satoshi Ono) to investigate. The most obvious possibility is that someone knocked on this man’s door and then persuaded him to turn around so he could be stabbed in the back. But if there was such a level of distrust that the man would not unchain the door, why would be casually turn his back on the attacker? So here we have a locked room and Kei Enomoto decides the only way in which he can unlock it is to understand the motive. This breaks his usual pattern which has ignored the people involved and focused on the facts.
This takes us inside the world of the professional Shogi players. The qualification event that’s currently causing waves offers the possibility a woman might finally reach the highest level. She has one more match to play and if she wins, she will make history. By a curious coincidence, the other man who has qualified for this final match should have played the deceased in a previous round. The form book says he would have lost, but there’s doubt as to whether this would give him a motive for murder. The female player also had a sexual relationship with the deceased, but immediately before and after the time of death, she was apparently calling the deceased from her home on the telephone landline (old technology). Although the theme for the motive is fairly obvious, there’s just enough in the rest of the story to keep this fresh and these represents another winning locked room.
The fourth episode, however, sees a slight misstep. Gou Serizawa’s beginning to gain some fame because he’s been taking the credit for solving these locked room puzzles. Normally, nothing would have persuaded him to accept this obviously fairly poor and rather obsessive man as a client but, with a photographer looking on, he’s trapped into accepting him.The man wants the lawyer to gain entry to an apartment that has been set up to keep an expensive collection of spiders. The man asserts a claim over two of the spiders but, with the collector dead, neither the mother nor the widow are prepared to allow him into the room. As the story is revealed, it seems the collector was found dead a few days ago. There was a security lock on the outside door and every single window, vent and drain through which a spider might otherwise have escaped, was covered by a mesh or taped up. It seems the collector was bitten by one of the spiders and died. But this is problematic because if he had known he was bitten, why did he not call for help? He was carrying a cellphone and there was a landline in the room. So, on the face of it, this is a very intriguing mystery, but the answer turns out to be one that might conceivably have worked if it had been in written form. We tend to find more things plausible when we see them in our mind’s eye. But as seen on the television screen, this strikes me as seriously implausible. This is unfortunate because, if you accept the basic premise, the various factors do all fit together perfectly.
