Starting in the late 1920’s the author began prowling the back streets and alleys of Paris, going where tourists dare not go and would not be welcome.  He mingled and took photos of the underside of Paris; the whores, pimps, cesspool cleaners, madams, opium dens, thieves, gays and gang leaders who lived in the dark alleys and byways of Paris at that time.  His was not an easy journey for those who he wished to talk too and photograph were often wanted by the police and they lived in a world where there was little honor and every outsider was view with suspicion and was also seen as an easy “mark”.
