When you watch this, please always keep in mind the title of the show: The Locked Room Mysteries. It isn't your typical detective drama wherein you spend the episode collecting clues, understanding the motive, having a selection of suspects and all the chasing and gun - pointing scenes in between. Some of the suspects may appear easy to point out from the beginning, but the point of this drama isn't the crime but how the room became a locked room and what it has to do with the case. It is a very clever drama as it teaches you about locked rooms and teaches you aspects of a case at the same time. It has an episodic nature, but you won't get bored with the routine. In fact, you look forward to watching Enomoto-san work every time. The drama is very plot-driven. Ohno Satoshi as Enomoto Kei was a delight to watch. The soundtrack is amazing and one of the best I have heard. This is a must-watch for anyone who wants a good drama to watch.
