My sister's grave

Seattle homicide detective Tracy Crosswhite lost her sister Sarah over 20 years ago. Although no corpse was discovered, there was still enough evidence to convict the man thought responsible for Sarah's disappearance, but Tracy doubts that the man in jail was responsible. When her sister's body is finally located, Tracy sets out to find the answers she has been seeking for two decades and catch the murderer she is sure is still on the loose.
