About This Book

Seventy-five-year-old retired FBI agent Ethel Fiona Crestwater is called back into action after her neighbor and close friend Sarah Phelps is found shot to death beside an unidentified man. The apparent murder-suicide does not withstand Ethel's scrutiny, and the evidence points toward a calculated scheme targeting wealthy senior citizens.

Drawing on a lifetime of investigative experience and a formidable network spanning law enforcement and the underworld, Ethel goes undercover to expose the people behind the killings. The deeper she enters their web of lies and threats, the greater the risk that seeking justice for Sarah will cost Ethel her own life.
