I had never thought about how a psychologist and a detective would collide. In my previous life, I had never thought about it. One focused on the motive of the crime and the other focused more on the basis of physical evidence. Later I learned that the two were not as incompatible as they seemed on the surface. On the contrary, the two were more harmonious than I thought. Just as I later discovered slowly that it was so difficult to erase Sherlock Holmes from my life.
