The Vital Message by Sir Arthur Conan Doyle is a powerful follow-up to his earlier work The New Revelation, in which the famous creator of Sherlock Holmes turns his attention to Spiritualism and life after death. In this profound and deeply personal volume, Conan Doyle defends spirit communication, shares testimonies from séances and psychic phenomena, and argues for the continuity of life beyond the grave. Written shortly after World War I, this book expresses a message of hope, healing, and faith in the unseen, aimed at a generation devastated by loss.
