OK.  I did go back to the dark alley with my voice recorder at about 1:00 in the morning.  The streets were empty with the exception of some young ruffians fighting in the street (this is true).   I furtively stalked past them through cobble stoned back alleys until I found prostitute row again.  I asked a few leading stupid questions to try and elicit communication but alas....nothing,..nada.  I furtively crept back to the hotel, tiptoed past the front desk and ran like hell up the stairs to the 5th floor.  I don't think anyone saw me.  I am now enroute to New Castle for my paranormal event.  http://idealeventmanage.com/hillviewmanor.html
