Malice

At the crime scene, Police Detective Kyochiro Kaga recognizes Hidaka's best friend, Osamu Nonoguchi. Years ago when they were both teachers, they were colleagues at the same public school. Kaga went on to join the police force while Nonoguchi eventually left to become a full-time writer, though with not nearly the success of his friend Hidaka. As Kaga investigates, he uncovers evidence that the two writers' had been 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.
