Piercing - Murakami, Ryu

Every night, Kawashima Masayuki creeps from his bed and watches over his baby girl's crib while his wife sleeps. But this is no ordinary domestic scene. He has an ice pick in his hand, and a barely controllable desire to use it. Deciding to confront his demons, Kawashima sets into motion a chain of events seeming to lead inexorably to murder.
