"e;The People of the Abyss"e; (1903) is a book by Jack London about life in the East End of London in 1902. He wrote this first-hand account after living in the East End for several weeks, sometimes staying in workhouses or sleeping on the streets. In his attempt to understand the working-class of this deprived area of London the author stayed as a lodger with a poor family. The conditions he experienced and wrote about were the same as those endured by an estimated 500,000 of the contemporary London poor. London also used the expression "e;the people of the abyss"e; in his later dystopian novel "e;The Iron Heel"e;. (Wikipedia)
