This book that is the Affair Mutilated Mink is recommended by the newspaper.
According to Newspaper in Japan,
"People won't be able to guess who a criminal is until end of the novel".
So I bought it, and read it.
As the newspaper says so, I couldn't guess the criminal.

This "The Affair Mutilated Mink" is actually series 2.
The series 1 is "The Affair of the Bloodstained Egg-Cosy".
I haven't bought it yet.
But I will buy it, soon.

The series 1 wasn't introduced by newspaper,
so it may be easy for reader to guess who the criminal is.
But I wanna buy it, even if it is easy to guess the criminal. :D
