We write to expose the unexposed. If there is one door in the castle you have been told not to go through, you must. Otherwise, you'll just be rearranging furniture in rooms you've already been in. Most human beings are dedicated to keeping that one door shut. But the writer's job is to see what's behind it, to see the bleak unspeakable stuff, and to turn the unspeakable into words -- not just into any words but if you can, into rhythm and blues.
