The young Robert Louis Stevenson, living in a boarding house in San Francisco in the 19th century while waiting for his beloved’s divorce from her feckless husband, dreamed of writing a soaring novel about his landlady’s adventurous and globe-trotting husband--but he never got around to it. And very soon thereafter he was married, headed home to Scotland, and on his way to becoming the most famous novelist in the world, after writing such classics as Treasure Island, The Strange Case of Dr. Jekyll and Mr. Hyde, and Kidnapped.
