My brother and I grew up with Robert Louis Stevenson’s “A Child’s Garden of Verses,” and when we were a little older, “Kidnapped” and “Treasure Island.” I still have all three books from the 1940s and ’50s. We never read “The Strange Case of Dr. Jekyll and Mr. Hyde,” nor was it read to us, but with Halloween fast approaching and that book considered by many critics to be Stevenson’s masterpiece, I thought I should.
