Ben MacIntyre (Agent Sonya)

Ben MacIntyre writes fantastic books about real life spies. Agent Sonya is another one. Ursula Kuczynski Burton was a spymaster, saboteur, bomb-maker and secret agent - who spent a large part of her career in rural Oxfordshire. Codenamed 'Agent Sonya', her story has never been told - until now.

From planning an assassination attempt on Hitler in Switzerland, to spying on the Japanese in Manchuria, to preventing nuclear war (or so she believed) by stealing the science of atomic weaponry from Britain to give to Moscow, Ursula conducted some of the most dangerous espionage operations of the twentieth century.

Simon Mayo, Matt Williams and all Books of the Year affiliates would like to make it very clear that Ben MacIntyre is not a spy and never has been a spy.
