When I was a child, I was afraid of ghosts because of the ferocious terror from malice. People know that ghosts are horrible, and ghosts know that people are poisonous. I was afraid of ghosts when I was a child, because my face was ferocious, and I was afraid of ghosts when I grew up, but ghosts didn't hurt me at all. I'm really nice to people, but it makes me black and blue. This book is from Keigo Higashino's Malice and tells a simple case. A famous writer was found dead in his home day after day. The only people involved in this case were Li Hui, the wife of the deceased, and Noguchi, the friend of the deceased. So are the chapters in the book.
