Dr. Maura Isles goes to see Peter Lucas, a Boston Tribune reporter, whom Joe Roke wanted as the media representative for a live interview from the hospital. They exchange information that both had gleaned from their respective investigations, his on the historical connections of Olena and Joe, and her medical perspective from the autopsy. Detective Rizzoli is troubled by the unknown Mila and decides to place an advertisement in
Confidental, a tabloid found on the back seat of Roke's car. Surveillance photos did show a third head in the back seat of his car when he had stopped for gas in Virginia.
Maura brings Peter Lucas to Jane and Gabriel's apartment, and they share conjectures about Balentree's involvement into this black market trade involving women, weapons, and drugs. A mysterious woman contacts Jane's number left in the
Confidential, but hangs up. Shortly, the bell rings at Jane's apartment and Mila appears at her doorstep. Mila is extremely frightened, but she does show Jane a VCR tape confiscated from the house in Asburn. A hidden camera in the main bedroom of the home caught the murder of a young girl by a prominent man from Washington. Mila informs Detective Rizzoli tha the three of them, Joe, Olena and herself, each had a copy before they were separated.
The house door bell sounds again, and Jane sees that FBI Agent John Barsanti is at her door. Quickly, she realizes that Mila will run again, grabs her gun and baby Regina, and follows Mila through the open bedroom window. Jane leads them to Peter Lucas's apartment where she is disarmed and discovers that Peter has been a paid informant for those in search of Mila and the three tapes. Mila escapes through the bathroom window, but Detective Rizzoli and her daughter Regina are forced by a second assailant into the woods and death.
Meanwhile, Gabriel is frantically trying to locate his wife by reviewing her last known steps and cell phone contacts. He is disturbed by Peter Lucas's responses to his questions after finding Lucas's number on Jane's cell phone call list and heads over to his apartment. Jane had been forced to dig a grave for herself and Regina deep in the woods behind Lucas's townhouse. She had looked for her weapon hidden in the diaper bag, but found nothing.
After Gabriel and Agent Baranti question Peter Lucas, Gabriel searches through his townhouse and finds Jane's car keys behind the sofa. He hears three gunshots behind the apartment and dashes off into the woods. Sharpened senses lead Gabriel farther into the woods where Jane stumbles forward holding Regina in her arms followed by Mila clutching Jane's weapon.
The novel's resolution includes the prosecution of the murderer and his loss of the federal job, Peter Lucas's fine and arraignment, and Mila's debriefing. Federal agents retrace the Russian girls illegal entry into the United States and, with Mila's help, locate the body of a young girl killed durng the journey. The story leads one to question how many young girls vanish in the hands of unscrupulous men posing as agents of promise and good fortune.
