Imagine a cool autumn night, the moon appears from behind the clouds casting shadows.  A fog rolls across the land.  Suddenly, the sound of hooves beating on the cold ground break the eerie silence.  Out of the mist an obscure figure atop a steaming horse comes towards you at a full gallop.  As the grim figure gets closer you can't believe your eyes. 

Can it be real or is it the night shadows playing tricks on you????
