Perfect Poison: A Female Serial Killer's Deadly Medicine

The true-crime story of a Massachusetts nurse with a dark secret, by the New York Times bestselling author of The Girl Left Behind.

At the Veterans Affairs Medical Center in Northampton, Massachusetts, Kristen Gilbert was known as a hardworking, dedicated nurse. Yet so many emergencies and sudden deaths occurred under Kristen's watch that others jokingly called her the “Angel of Death.” No one suspected the horrifying truth: that over the course of six months, Gilbert had caused the deaths of as many as forty patients. With new insight into the sociopathic mindset of nurses who kill, and the latest details on Gilbert's ongoing prison sentence, M. William Phelps exposes how one person's good intentions went so chillingly, killingly wrong . . .
