In 1916, at the height of the First World War, Doyle's belief in psychic phenomena was strengthened by what he took to be the psychic abilities of his children's nanny, Lily Loder Symonds.[79] This and the constant drumbeat of wartime deaths inspired him with the idea that spiritualism was what he called a "New Revelation"[80] sent by God to bring solace to the bereaved. He wrote a piece in Light magazine about his faith and began lecturing frequently on spiritualism.
