Depraved heart / Patricia Cornwell.

Dr. Kay Scarpetta is working a suspicious death scene in Cambridge, Massachusetts when an emergency alert sounds on her phone. A video link lands in her text messages and seems to be from her computer genius niece Lucy. But how can it be? It's clearly a surveillance film of Lucy taken almost twenty years ago. As Scarpetta watches she begins to learn frightening secrets about her beloved niece that raise dangerous legal implications, leaving Scarpetta confused, worried, and unable to turn to Lucy, her FBI husband Benton Wesley or her investigative partner Pete Marino. Cornwell launches these unforgettable characters on an intensely psychological odyssey that includes the mysterious death of a Hollywood mogul's daughter, aircraft wreckage on the bottom of the sea in the Bermuda triangle, a grisly gift left in the back of a crime scene truck, and videos from the past that threaten to destroy Scarpetta's entire world and everyone she loves.
