In 1961, Nombeko Mayeki is born a poor black girl in Soweto. She leaves the slums and in a twist of fate – is run over but survives – this puts her into the employ of the engineer who ran her over, as a cleaner in South Africa's secret nuclear weapons facility. Here, her good head for mathematics leads her to cover for her drunken and incompetent employer. Two Mossad agents eventually murder her employer, but she outwits them and escapes to Sweden with a trio of female Chinese con artists, but due to a mix-up, Nombeko ends up in possession of a missing South African atom bomb. In Sweden, she settles into a condemned building living in a bizarre commune including a pair of identical twins (both named Holger), the youngest of which and his girlfriend are die-hard republicans determined to end the Swedish monarchy. Nombeko and her Swedish boyfriend (the older Holger) are determined to hand the bomb over to the Swedish Prime Minister, but no-one will believe them. Years later, after several attempts to hand over the bomb have failed in absurd circumstances (including the remaining Mossad agent finding and nearly killing them), Holger and his girlfriend kidnap the King and the Prime Minister of Sweden on the spur of the moment from a gala banquet with Chinese President Hu Jintao at the Royal Palace in Stockholm, and prepare to blow up the bomb (and everything within a 38-mile radius) in order to end the monarchy. Nombeko calms the situation down, saving the King's life, and her own.^[4]
