Thomas Sugrue — There Is a River: The Story of Edgar Cayce (1942)
The only biography of Edgar Cayce written during his lifetime, authored by journalist Thomas Sugrue who lived with the Cayce family from 1939–1941. Published by Holt, Rinehart and Winston in 1942, it remains the foundational primary source documenting Cayce's life, medical readings, and psychic phenomena. Contains direct quotations from Cayce's readings, notable cases including the black sulphur remedy prescription, documentation of financial exploitation attempts, and the biographical chronology used by virtually all subsequent Cayce scholarship.
