In 1989, South Africa secretly built seven nuclear warheads. Six were dismantled under international observation. The seventh was never declared.
Thirty years later, in London, a retired cybersecurity expert David Hartley is content with green tea, Sunday lunch with his daughter and quiet retirement - until Emma, a Guardian journalist, hands him an encrypted file from his old life in Cape Town. The password is one only David would know. Inside is proof that the seventh warhead still exists. And someone wants the world to know.
A colleague is murdered on a London street. Emma's flat is ransacked. Within forty-eight hours, David and Emma are travelling on forged passports to a country David swore he had left behind. Hunted by an Ml6 agent with everything to lose and a former Armscor officer with everything to sell, they have less than a week to find the bomb before it disappears into the hands of the buyers, who will not hesitate to use it.
From the wine farms of Franschhoek to a hangar at OR Tambo airport, The Last Warhead is a propulsive espionage thriller about the secrets governments bury - and the price of digging them up.
