<p>Robert Louis Stevenson&rsquo;s classic tale takes to intriguing extremes the widely-held belief that everyone has good and bad sides. First published in 1886, the story is justly famous; it has spawned countless stage and film adaptations and &ldquo;Jekyll and Hyde&rdquo; has entered the English language as an epithet for someone whose personality oscillates between extremes.</p><p>&nbsp;&nbsp; Stevenson&rsquo;s tale was inspired by the true story of Edinburgh cabinet maker and locksmith, William (Deacon) Brodie, a respected businessman by day and thief by night.&nbsp; Brodie was caught and hanged in 1788, on gallows that many believe he himself helped to design.</p>
