He thought how easy it would be to write an entire book on Johannesburg violence. The strike leader Pickaxe Mary, after whom Mary Fitzgerald Square was named, who attacked her enemies with a pickaxe handle. The trenches dug into the streets of Fordsburg during the 1922 miners’ strike. The cannons of the government aimed at the poor whites of Vrededorp. The murdered woman in the 1960s whose head was found in the Zoo Lake and whose torso was discovered in a suitcase in Wemmer Pan. Jan Smuts, who wanted to bomb striking workers with aeroplanes. The countless schoolchildren shot during the 1976 uprising. The fifty-three supporters who were shot down in the street outside Shell House, the ANC headquarters. The huge bomb that went off shortly before the first democratic election and made a whole row of shops kneel down on the pavements of Bree Street. The commuters, in the early 1990s, killed by pangas or who jumped to their deaths from moving trains to escape their Portuguese-speaking attackers. The murderess Daisy de Melker, whose third husband survived only because she was caught in time. The violent home invasions, rapes and hijackings he read about in the newspapers every day.
