The Van Der Byl Diamond Company, willed by its founder to his son Benedict, turns out to be a bequest of hatred. For it is couched in such terms as to offer him the instrument of destruction of his bitterest rival. "Destroy Johnny" is the old man's implacable message. And so, consumed with envy for his own foster-brother, Benedict sets out in ruthless pursuit of this goal - and Johnny is plunged into a maelstrom of greed, vengeance, and murder.
The Diamond Hunters moves from Cape Town to London and back, from the sandstorms of the South African coastal deserts to the icy wastes of the South Atlantic.
