Rizzoli & Isles return; in the nail-biting new thriller from Sunday Times bestselling author Tess Gerritsen. The murder of Sofia Suarez is both gruesome and seemingly senseless. Why would anyone target a respected nurse who was well-liked by her friends and her neighbours? As Detective Jane Rizzoli and Forensic Pathologist Maura Isles investigate the baffling case; they discover that Sofia was guarding a dangerous secret -- a secret that may have led the killer straight to her door. Meanwhile; Jane's mother Angela Rizzoli is conducting an investigation of her own. She may be a housewife; not a police detective; but she's savvy enough to know there's something very strange; perhaps even dangerous; about the new neighbours across the street. The problem is; no one believes her; not even her own daughter. Immersed in the hunt for Sofia's killer; Jane and Maura are too busy to pay attention to Angela's fears. With no one listening to her; and danger mounting in her neighbourhood; Angela just may be forced to take action on her own...
