In this chilling true crime thriller by New York Times bestselling journalist M. William Phelps, a woman's mysterious death in upstate New York plunges her family into a nightmare of backstabbing and vengeance...   In July 2015, Mary Yoder fell ill in the chiropractic center she operated with her husband, Bill. Doctors in the ER and ICU were baffled--and unable to save her life. Weeks later, her family received startling news from the medical examiner: Mary had been deliberately poisoned. Another shock followed when the local sheriff received a claim that Adam Yoder had poisoned his mother. But Adam was not the only person of interest...   Kaitlyn Conley, Adam's ex-girlfriend, worked at the Yoders' clinic and was at Mary's bedside during her last hours. Still, some spoke of her history of rage-fueled behavior. Had Kaitlyn and Adam conspired to kill Mary? Yet another suspect emerged when accusations were hurled at grieving husband Bill Yoder...   M. William Phelps unravels a twisting trail of evidence to reveal the heartless scheme that tore a family apart, divided a community, and culminated in two gripping, high-profile trials.
