I received this book as an Advanced Readers Copy from Goodreads. Thanks, Goodreads.
This book was very good. It is the story of Yasuko who is divorced and lives with her daughter. Her ex-husband finds her and begins to harass her and her daughter, Misato. After a struggle, he ends up dead on their floor. Next door neighbor, Ishigami, hears the commotion and helps her dispose of the body and gives her and her daughter specific instructions on what to do, say and behave when questioned by the police. Police detective, Kusanagi, enlists the help of a genius from the university, Dr. Yukawa. Yukawa went to school with Ishigami. Yukawa thinks Ishigami had something to do with the murder, but can’t put his finger on it. This book was very exciting and intriguing. Loved it.
