The Japanese version of the mystery ranking in fiscal 2019 is the reason why this work won the first place. Certainly there is a big mechanism at the end, and there is a big surprise, but since the overall setting is zero reality, if you are not familiar with this kind of work, it may feel a little childish work.
The overseas version was an overwhelming victory for this work. This is a place where there is no objection. The structure of the author himself as Watson, and the whole hidden line was also wonderful.
