Namibia in January. In the affluent Ludwigsdorf district of Windhoek, the children are taking an evening dip in the pool when the man who waters the lemon trees is shot.
Nineteen years after the murder of SWAPO attorney Anton Lubowski, there’s a new series of assassinations. The victims are all members of the South African secret police. The young detective Clemencia Garises is suddenly confronted with the bitter battles from the final days of apartheid, something she previously only knew about from stories. Her job is to find the killer and protect the racist perpetrators of past crimes. But her adversary, the killer, is playing a game of cat and mouse. He carries out assassinations in a neighborhood full of luxury villas, gains access to a South African prison, smuggles an AK-47 across the border and waits patiently beneath an acacia tree in the middle of the Kalahari desert for his next victim. He’s fatally ill, he’s alone, and he keeps on killing. Clemencia quickly realizes that this is an avenging angel exacting a toll for past crimes. But who is the killer? And why did he wait two decades to take his revenge?
