Toronto Police Chief, Mark Saunders, was interviewed recently regarding his son diagnosed with high-ability autism.  It's a tragic situation for anyone to cope with every day.  Anthea Fraser published "The Macbeth Prophecy" in 1997 which addressed the depth of the unsolvable angst; i.e., the never-ending dread and anxiety.  She described it as being like having the brain crushed and "repeatedly battered with a heavy instrument."  The name of the young character was "Mark Saunders".
