Dr. Kay Scarpetta is working a highly suspicious death scene in a historic home in Cambridge, Massachusetts when an emergency alert sounds on her phone. A video link lands in her text messages, immediately begins playing... and seems to be from her niece Lucy. But how can it be? It’s clearly a surveillance film of Lucy taken almost twenty years ago.
As Scarpetta watches she comes to grips with frightening secrets about her niece, whom she loves like a daughter. That first clip and others sent soon after raise dangerous implications that increasingly isolate Scarpetta and leave her confused, alarmed, and not knowing where to turn. She doesn’t know whom she can tell – not her FBI agent husband, Benton Wesley, or her investigative partner, Pete Marino. Not even Lucy.
Cornwell launches these unforgettable characters on an intensely psychological odyssey that includes the bizarre death of a Hollywood mogul’s daughter, 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. The diabolical presence and singularly "depraved heart" behind what unfolds seems obvious - but strangely, not to the FBI. Certainly that’s the message they send when they start harassing Lucy and begin building a case that could send her to prison for the rest of her life.
