After working on one of the worst mass killings in US history, Chief Medical Examiner Kay Scarpetta returns home to recover, only to receive an unsettling call-out. The body of a young woman has been discovered inside the sheltered gates of MIT, draped in an unusual cloth and posed in a way that is too deliberate to be the killer's first strike. A preliminary examination reveals that the corpse is covered in a fine dust that, under ultraviolet light, fluoresces blood-red, emerald-green and bluish-purple. As Scarpetta pieces together the fragments of evidence, she and her team are drawn deeper into the dark world of designer drugs, drone technology, organised crime, and shocking corruption at the highest level.
