Chasing Darkness

It is fire season, and the hills of Los Angeles are burning. Threatened by a raging brush fire, the residents of Laurel Canyon are being forced from their homes. Police and Fire Department personnel rush from door-to-door to evacuate the inhabitants, but find something in one of the houses none of them expected: The days-old corpse of a middle-aged recluse who apparently committed suicide. Then comes an even more horrible discovery: Clutched in his lap is a photo album containing photographs of seven young women who have been murdered. Each photograph was taken only moments after the women were killed, and could only have been taken by the killer. One murder per year for seven years, their bodies found in different parts of the city. LAPD homicide detectives had never connected the seven murders. But now with the discovery of the "death album" these seven murders have been linked, and the news for Elvis Cole is bad...Only one suspect had been charged in any of those cases, that being for the murder of victim #4. LAPD and the LA County District Attorney's office had a marginal case, but they also had a recorded confession by the suspect and believed him to be the murderer.
But, with evidence supplied by Elvis Cole, in the end he walked free. That suspect was the suicide now discovered in the fire, Elliot Martin. Did Cole's action three years ago free a killer to commit more murders? Did Elvis cost three young women their lives?
