The June 18 1934 edition of the Toronto Daily Star contained this advertisement for an upcoming novel that the paper was planning to serialize:
Philip Gibbs (1877-1962) was a journalist and official war correspondent for Britain during the First World War, for which he was knighted in 1920. He was a prolific writer, but he appears to have focused mostly on non-fiction. The list of his works in his Wikipedia page mentions that he occasionally wrote novels, but does not include Spotlight on Paradise. I can find no mention of it anywhere.
