THE VITAL MESSAGE
The Vital Message', first published in 1918, was Conan Doyle's second book devoted solely to his thoughts on Life after death, written after his debut book on the subject; 'The New Revelation'. "In "The Vital Message" the sun has risen higher, and one sees more clearly and broadly what our new relations with the Unseen may be."
