My original review has disappeared, along with all my other reviews from 2015 :(.
At any rate, this is the first novel by Keigo Higashino I read, and it blew me away and made me a Higashino fan for life. The plot is meticulously developed and wonderfully paced, and my heart went out to Ishigami. I love this book. I haven't been this smitted by a mystery since I first fell in love with Sherlock Holmes. This is what mystery writing should be!
