My 4th (fave so far!) book by him & I have such respect for Higashino. This is a crime novel that has solid science/research explaining things; a side story that becomes a metaphor for the main plot, & a deep back story that serves as foundation & gives a lesson (the Prof's rel'nship with the kid is my favourite!) that's sure to make you go through all sorts of emotions. I'm glad I didn't listen to the reviews saying it had too much science in it!
