Ben Du Toit teaches history and geography in Johannesburg, South Africa. It is the period of the height of the youth riots in the township of Soweto. At Ben's school, Gordon Ngubene, a native, is a cleaner and he occasionally does little chores for Ben. When Ben sees that Jonathan, Gordon's son, is showing signs of intelligence and diligence, he decides to partly finance his education. One day however, Jonathan takes part in a demonstration which ends up in a violent riot and is arrested by the police. A few weeks later, after a harrowing quest through countless offices, Ben and Gordon are informed that Jonathan died "of natural causes" while in detention.
Due to the mystery surrounding his son's death, Gordon gives up his job in order to devote himself entirely to the enquiries which have become an obsession with him. Both the Special Branch and the Security Police are annoyed about Gordon's insistence and soon enough Gordon is arrested. After numerous attempts to try to trace Gordon and speak to him, Ben and Gordon's wife Emily are told by the spokesman of the Security Police that Gordon apparently committed suicide by hanging himself with strips torn from his blanket.
But Ben Du Toit senses that the official explanations for both Jonathan's and Gordon's deaths are just a pretext for poorly disguised murders and so he decides to take matters in his own hands and starts investigating.
Mr Brink's novel is a harrowing account of a solitary man's fight against all the atrocities of the Apartheid. During this dark period in the history of South Africa, a white man had to be a real hero to fight for the right of the Afrikaners. The author beautifully captures the fact that Ben has to fight not only the resentment of the people of the other race, but also that of the people belonging to his own race - his family for a start. The descriptions of the townships of Johannesburg, particularly that of Soweto, are breathtaking in their accuracy and poignancy.
