"Inspector Kurt Wallander returns this time to investigate a horrific crime in his Scandinavian homeland somehow linked to a troubled apartheid-era South Africa. When the tenacious sleuth's search for the truth behind the execution-style killing of a Swedish housewife uncovers a plot to assassinate Nelson Mandela, Wallander finds himself in a tangle with the South African secret service and a ruthless ex-KGB agent." --
