On August 25, 1928, a black sedan pulled into the dusty circular driveway of a farmhouse in the tiny rural community of Catawissa, Missouri. The sheriff of St. Louis County emerged from the vehicle and walked slowly up the front steps. A middle-aged farmwife answered his knock. She spoke quietly with him, excused herself to powder her face, then allowed herself to be led outside and taken away. Authorities sought to question her in a mystery which had been building for twenty years: Was she a selfless saint who voluntarily cared for the acutely ill in order to nurse them back to health and restore them to their families, or a minister of death whose crimes would qualify her as America’s first female serial killer? In this riveting nonfiction memoir, S. Kay Murphy recounts the tale of searching for the truth about her great-grandmother—accused murderer Bertha Gifford.
