#1 New York Times bestselling author Patricia Cornwell returns with another scintillating thriller in her high-stakes series starring medical examiner Dr. Kay Scarpetta.

On a hot evening in Cambridge, Massachusetts, Dr. Kay Scarpetta investigates a dead bicyclist who was attacked with almost super human force. Before she's notified, her FBI agent husband receives a suspicious call, allegedly from Interpol. It becomes apparent that an onslaught of interference and harassment might be the work of the cyberbully Tailend Charlie, who has been sending cryptic communications to Scarpetta. Even her brilliant tech-savvy niece, Lucy, can't trace whoever it is. When a second death hundreds of miles south shocks Scarpetta to her core, she's confronted with something far bigger and more dangerous than she'd ever imagined.

Patricia Cornwell is recognized as one of the world's top bestselling crime authors with novels translated into thirty-six languages in more than 120 countries. Her novels have won numerous prestigious awards including the Edgar, the Creasey, the Anthony, the Macavity, and the Prix du Roman d'Aventure. Beyond the Scarpetta series, Patricia has written a definitive book about Jack the Ripper, a biography, and three more fiction series among others. Cornwell, a licensed helicopter pilot and scuba diver, actively researches the forensic technologies that inform her work. She was born in Miami, grew up in Montreat, North Carolina, and now lives and works in Boston.
