Kagi no kakatta heya is the TV drama adaptation of Kishi Yuusuke's series of locked room mysteries featuring young attorney Aoto Junko and security consultant (professional thief??) Enomoto Kei. The stories were collected under the name of the third book/second short story collection in the series and Aoto's boss Serizawa was added to the main cast. Each episode is about a case where Enomoto has to explain a locked room scenario so that Aoto and Serizawa can prove someone's innocence in a murder case or find the culprit in what at first seemed like a suicide. So yes, a whole series that deals solely with locked rooms! How awesome is that? Pretty much, but due to time restraints and the relatively continuous theme and structure of the episodes, I'll just illustrate my Top 3 and give a final opinion of the whole series.
