It's a foggy night in the city.  The haze makes everything blur and meld together.  Shadows and lights move in inexplicable ways.  Mysterious figures wander though a landscape draped by a gray, transparent veil.  Half heard sounds echo in distant side streets and alleys.  The big hand meets the little hand at the top of the circle - the infamous hour.  Are you alone?  You may think so, but can you be sure?  Can you really be sure?  Just keep walking.
