Keigo Higashino

Keigo Higashino (東野 圭吾 ) is my all time favorite author. He is well-know of mystery novel as well as touch the deepest mind of people- dilemma between devil and angel site. Some male or female protagonist in his novel will face a situation like to become devil to achieve revenge (killing ppl)  or angel to accept punishment and give up revenge. His main novels are 容疑者Xの献身, 秘密, 白夜行 and so on. I haven't see all his novel yet, until now my favorite novels are 白夜行 and さまよう刃.
