When an ancient mummy is discovered in the basement of a museum in down-town Boston, excitement starts to mount. Under the glare of a media frenzy, the mummy is taken to hospital for a CT scan. Forensic pathologist Maura Isles is also invited to attend.
As the CT scan proceeds everyone in the room leans in - and gasps in horror as an image of a bullet is revealed. Maura declares it a possible homicide, and calls in detective Jane Rizzoli.
When the preserved body of a second victim is found, and then a third, it becomes clear that taking their lives is not enough for this terrifying killer. And that unless Maura and Jane can find and stop him, he will soon be adding yet another chilling piece to his monstrous collection.
