Tess Gerritsen: Keeping the Dead [2009] hardback

She's Pilgrim Hospital's most unusual patient, and on this Saturday night, a media circus is gathered to record every minute of her visit to the X-ray department. Crammed into the small CT scan room are reporters, TV cameras, a select group of medical technicians - and forensic pathologist Maura Isles. Maura is there because the patient being scanned tonight isn't alive. She's probably been dead for centuries. She is, in fact, a mummy. As the CT scan proceeds, everyone in the room leans in close - and gasps in horror as an image of a bullet is revealed. Maura declares it a possible homicide case and calls in Detective Jane Rizzoli. When the preserved body of a second victim is found - and then a third - it becomes all too clear that not only is a maniac at large but he is taunting them. And that, unless Maura and Jane can find and stop him, he will soon be adding yet another chilling piece to his monstrous collection.
