A South African antiques dealer is murdered with a single bullet from an M-16 assault rifle. The contents of his safe are missing, and the only clues are a scrap of blank paper and the unusual weapon used: a gun that's generally the choice of mercenaries, not burglars. Now ex-cop Zed van Heerden has seven days to fill in the blanks in this dead man's past - a past that appears only to start in 1983.
