I will stick to my resolution to always be reading a book by Keigo HIGASHINO. I found that reading several books at the same time in Japanese is the best way to avoid loss of interest or discouragement.
I am so sure that I will love any book by Higashino that I just pick them randomly and never read the summary on the back cover. But I am surprised by『手紙』. It is hard to tell where the story will lead us, and I suspect the book to be more a social portrait than a crime novel. I already noticed that Higashino gives a social dimension to some of his books, and I would not be surprised if 『手紙』fell in this category.
The book is divided into 6 chapters, and I have only read the first one. To me, this book is like a focus on what is usually dismissed in crime stories: the daily life and hardship of the persons involved. Usually, a novel would concentrate on the plot, the investigation, and while it lets us glimpse at the suffering of the actors involved, especially the ones surrounding the victims, it rarely bothers to show us how, say, the brother of the murderer adjusts to his new condition and goes on with this life.
I think that this is what 『手紙』will do, though the novel might still change direction. In any case, it is a little different from what I expected, but I enjoy reading it all the more.
