Arthur Conan Doyle (1859 – 1930) is best known for stories rather than novels as such. A Scot, he was a medical doctor who became a writer, most noted for his fictional stories about the detective Sherlock Holmes, which are generally considered milestones in the field of crime fiction. He also wrote about a second fictional character of his own invention, Professor Challenger, and for popularising the mystery of the Mary Celeste. He was a prolific writer whose other works include fantasy and science fiction stories, plays, romances, poetry, non-fiction and historical novels. I've read all the Sherlock stuff but nothing else. He was born exactly a hundred years before me (and Morrissey of the Smiths).
Bonhoeffer uses a similar phrase 'worldly Christianity'. It's J Gresham Machen that I want to line up most closely with. See his Christianity and culture here. Having done commentaries on Proverbs (Heavenly Wisdom) and Song of Songs (Heavenly Love), a matching title for Ecclesiastes would be Heavenly Worldliness. For my stance on worldliness, see 3 posts here.
