In My Religion, Arthur Conan Doyle strips away the cloak of the detective novelist to speak candidly, passionately, and profoundly about the spiritual beliefs that defined his later years. Far beyond fiction, this autobiographical essay serves as a deeply personal declaration of faith—his unwavering belief in spiritualism as a legitimate and necessary evolution of religious thought. Addressing skeptics and seekers alike, Doyle recounts the experiences, revelations, and convictions that led him away from traditional Christianity and into a world of spirit communication, séances, and metaphysical exploration. With the earnestness of a true believer and the clarity of a seasoned writer, Doyle defends his controversial position not as a fringe obsession but as a vital spiritual awakening. My Religion is an illuminating, courageous document of belief from one of the most famous literary minds of his time.
