Book lovers must be agog around the world at the news that a sequel to “To Kill A Mockingbird” is to published later this year.  Written in the 1950’s and thought to be lost  “Go Set A Watchman” features character Scout as an adult.  This will bring an end to all those stories of Harper Lee as the ultimate sufferer of “writer’s block.”  Like many people, “Mockingbird” is one of my favourite novels so I’m feeling great anticipation and more than a little bit nervous about reading it.   Is this the longest ever gap between publication of first and second novels?
