Book excerpt: An exploration of the slums of London's Whitechapel area, exposing its grim poverty and the dire consequences of Victorian attitudes towards the dispossessed. The scenes of slum life ae incisively viewed through the eyes of a young captain in the Salvation Army, whose sense of moral outrage leads him on a journey through the despair of the East End ghetto. In his work within London's netherworld there is a manifestation of both desperation and hope which mirrored Harkness's own evolving vision of Christian socialism. Not only an important social documentary of the times, In Darkest London is also a text in the history of late Victorian ideas and values.
