Treachery times two
(Book)

"On Hawaii Island, a volcanic earthquake disrupts an abandoned cemetery--unearthing the body of a woman mutilated by her killer to conceal her identity. The search for her identity leads Hilo Hawaii's Chief Detective Koa Kane to a mysterious defense contractor with a politically connected board of directors. Defying his chief of police, Koa pursues the killer, only to become entangled in an FBI espionage investigation of Deimos, a powerful secret military weapon... At the same time, Koa--a cop who thirty years earlier killed his father's nemesis and covered up the murder--faces exposure by the dead man's grandson. Koa is forced to investigate his own homicide, and step by step, his cover-up unravels until another man is falsely accused."--Dust jacket flap.
