'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."

Sir Arthur Conan Doyle was one of Britain's most celebrated writers with his invention of the ultimate detective, Sherlock Holmes, completely altering the crime-fiction genre of the late 19th century. As well as this he was a pioneering sportsman, a doctor of medicine, and champion of the underdog, helping to free two men who were unjustly imprisoned. Of most importance to the man himself, however, was his belief in life after death and the spreading of the 'vital message'.

He received his degree in medicine from the University of Edinburgh in 1881 and by this time had already began investigating Spiritualism and had began attending séances, a fact that rebuffs the more common idea that he found Spiritualism after his son Kingsley died in 1918. In fact, by that time, not only had he studied Spiritualism for almost 30 years, he had declared the fact and spoken publicly about his beliefs. His first book on the afterlife, 'The New Revelation', was published in March 1918, some months before Kingsley's death.

By now World War One was raging and peoples thoughts were on the dead and dying, and Doyle himself is quoted as saying;

"I might have drifted on my whole life as a psychical researcher...but the War came, and it brought earnestness into all our souls and made us look more closely at our own beliefs and reassess our values."

In 1919, Doyle wrote 'The Vital Message' where he shares his thoughts on Skepticism, Religion, Psychic Phenomena, and Jesus.

Doyle saw Jesus as highest of spiritual beings and writes in 'The Vital Message'

Spirits have their individuality of view, and some carry over strong earthly prepossessions which they do not easily shed; but reading many authentic spirit communications one finds that the idea of redemption is hardly ever spoken of, while that of example and influence is forever insisted upon. In them Christ is the highest spirit known, the Son of God, as we all are, but nearer to God, and therefore in a more particular sense His son.
