One moment Kenniston was strolling down the quiet street, lost in pleasant reverie. The next moment the sky split open! It split wide open, and above them was a burn and a blaze of light - so swift, so violent, that the air itself seemed to have burst into flame. Then there was silence - awful, suffocating silence. Kenniston felt the chill of premonition - a shapeless terror that grew into a thing too evil to be borne alone.
