We Thought We Knew You

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 accusations 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.
