London's Underworld

The odds and ends of humanity, so plentiful in London's great city, have for many years largely constituted my circle of friends and acquaintances. They are strange people, for each of them is, or was, possessed of some dominating vice, passion, whim or weakness which made him incapable of fulfilling the ordinary duties of respectable citizenship. They had all descended from the Upper World, to live out strange lives, or die early deaths in the mysterious but all pervading world below the line.
