[Machine Translation] Aida, a former burglar, happens to be present when his nephew commits what appears to be a charcoal briquette suicide. The door was locked with a thumbturn lock, and the room was completely locked up. However, Enomoto, a crime prevention consultant (who is a thief in his own right? ) and lawyer Junko suspect that this is a premeditated murder ("Keyed Room"). In addition, there are four other amazing secret room tricks, including a secret room in a defective house and a secret room in the middle of a stage performance. Can you solve these locked rooms? This is the third installment in the crime prevention detective Enomoto series.
