Mayhew points out that Tom-All-Alones or rookeries such 
   as at St. Giles have a population of thieves, poor 
   vagrants, and the honest poor who worked in omnibus 
   and cab-yards [carriages], factories, etc., as well 
   as prostitutes and cadgers ["
London Labour and the 
   London Poor" Volume IV ("Those That Will Not Work, 
   comprising Prostitutes, Thieves, Swindlers and Beggars, 
   by several contributors"), Dover Publications, Inc., 
   New York, 1968, p. 299]. In addition, 
   Mayhew provides a good physical description:
     
       - 
         "...with an almost endless intricacy of courts 
         and yards crossing each other, rendering the 
         place like a rabbit-warren." [Mayhew Vol. IV, p. 299]
       
 
  .
       - 
         "... with the connected backyards and low walls 
         in the rear of the street, afforded and easy 
         escape to any thief when pursued by officers of 
         justice." [Mayhew Vol. IV, p. 299]
       
 
  .
       - 
         "In one of the cellars was a large cesspool, 
         covered in such a way that a stranger would 
         likely step into it. In the same cellar was a 
         hole about two feet square, leading to the next 
         cellar, and thence by a similar hole into the 
         cellar of a house in [another street]."
         [Mayhew Vol. IV, p. 300]
       
 
  .
       - 
         "...lodging-houses for theieves, prostitutes, 
         and cadgers. [...] If the beds were occupied 
         six nights by the same parties, and all dues 
         paid, the seventh night (Sunday) was not 
         charged for." [Mayhew Vol. IV, p. 299]
       
 
  .
       - 
         "...often from twelve to thirty persons 
         lodged in a room. At the back of this 
         public-house is a yard, on the right-hand 
         side of which is an apartment then 
         occupied by thirty-eight men, women, and 
         children, all lying indiscriminately on the 
         floor." [Mayhew Vol. IV, p. 301]
       
 
  .

         Prostitutes (lorettes or licentious women 
         or Cyprians or Paphians) could be cheap or 
         higher-classed. Cheap prostitutes (transpontine 
         women) often picked up her customers 
         indiscriminately at such places as 
         Haymarket, 
         Burlington Arcade or the 
         New Cut prominade. 
         Higher class prostitutes were found at 
         "night houses" 
         such as "Kate Hamilton's" or other such gathering 
         places and supper-rooms (restaurants), cafés 
         or parks.
