Jan Oscar Sverre Lucien Henri Guillou was born in Sweden in January 1944. He made his name as a journalist and rose to fame when he exposed a secret intelligence organisation, was convicted of espionage and spent 10 months in prison, 5 of which were spent in solitary confinement. He is now a bestselling novelist and writes regularly for Sweden’s leading tabloid, commenting on current affaris.

'He has a remarkable grasp of the mindset of the period and always puts the emphasis where it would be for the people involved at hat time, rather than ours.
