Acclaimed bestselling novelist Kunihiko Hidaka is found brutally murdered in his home on the night before he's planning to leave Japan and relocate to Vancouver. His body is found in his office, a locked room, within his locked house, by his wife and his best friend, both of whom have rock solid alibis. Or so it seems.
At the crime scene, Police Detective Kyochiro Kaga recognizes Hidaka's best friend, Osamu Nonoguchi.
As Kaga investigates, he eventually uncovers evidence that indicates that the two writers' relationship was very different that they claimed, that they were anything but best friends. But the question before Kaga isn't necessarily who, or how, but why. In a brilliantly realized tale of cat and mouse, the detective and the killer battle over the truth of the past and how events that led to the murder really unfolded. And if Kaga isn't able to uncover and prove why the murder was committed, then the truth may never come out.
