LAPD homicide lieutenant Milo Sturgis is a master detective. But Milo doesn't call his best friend, the brilliant psychologist Alex Delaware, in unless cases are "different." This murder warrants an immediate call. A hard-to-fathom, mega-rich young woman obsessed with reopening the coldest of cases: the decades-old death of the mother she never knew. The facts describe a likely loser case: a mysterious woman found with a bullet in her head in a torched Cadillac that has overturned on infamously treacherous Mulholland Drive. No physical evidence, no witnesses, no apparent motive. But as Delaware and Sturgis begin digging, the mist begins to lift. Too many coincidences. Facts turn out to be anything but. And as they soon discover, very real threats are lurking in the present.
