Some have mistakenly assumed that Doyle's turn to spiritualism was prompted by the death of his son Kingsley, but Doyle began presenting himself publicly as a spiritualist in 1916, and Kingsley died on 28 October 1918 (from pneumonia contracted during his convalescence after being seriously wounded in the 1916 Battle of the Somme).[1] Nevertheless, the war-related deaths of many people who were close to him appears to have even further strengthened his long-held belief in life after death and spirit communication.
