The eagerly anticipated new Rizzoli & Isles thriller, from the multi-million copy, No.1 bestselling author Rizzoli & Isles return, in the nail-biting, new Sunday Times bestselling thriller from 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 watchful mother Angela Rizzoli is conducting an investigation of her own. She may be a grandmother, 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.

With no one listening to her, and danger mounting in her neighbourhood, Angela just may be forced to take action on her own...
