The novel opens after midnight on a hot summer night, when many of the residents of the Jago, likened to "great rats", prefer to sleep in the street to avoid the oppressive heat and stench of the closely packed houses. A man lured into a dwelling by a woman is brutally coshed, robbed and dragged unconscious into the street where others remove his boots. Dicky Perrott, 8 or 9 years old (the uncertainty is telling) makes his way home to the single room in which his family dwells, where he finds his mother, Hannah Perrott and flea-bitten baby sister, Looey, but only a crust of bread to eat. As dawn breaks his father, Josh Perrott, returns home with a club sticky with blood and hair, suggesting another robbery.
