Robert Louis Stevenson's The Strange Case of Dr. Jekyll and Mr. Hyde is a lesson in suspense. Stevenson creates one singular point of mystery that successfully sustains reader intrigue and anxiety across nine tightly written chapters. Speaking as a writer: bravo, RLS, bravo. The simplicity of the central question - excuse me, Mr. Hyde, who exactly are you? - is highly effective. The entirety of Stevenson's narrative stems from this predicament. The suspense comes from an absence of knowledge. We, the reader, know nothing. Sure, Enfield tells a fairly bone-chilling story about a monster who stomps on a little girl at 3:00 am, but Hyde remains an enigma. Stevenson plays on natural human curiosity by piquing interest with a perturbing opening tale, then rests, and uses Utterson's ignorance as a buffer to withhold information. Seriously, who is Hyde?
