A Midsummer's Equation - Keigo Higashino

Higashino has a sense of fair play, but he still knows how to sneak a few surprises into the mix, and when a certain truth was revealed, I felt like I'd been punched in the stomach. This is the third novel I've read by this author, and I'm looking forward to reading his Malice in the near future. He has a way of dropping clues without making the web easy to unravel.
