In June 1917, Maugham was asked by Sir William Wiseman, an officer of the British Secret Intelligence Service (later named MI6), to undertake a special mission in Russia. It was part of an attempt to keep the Provisional Government in power and Russia in the war, by countering German pacifist propaganda. Two and a half months later, the Bolsheviks took control. Maugham subsequently said that if he had been able to get there six months earlier, he might have succeeded. Quiet and observant, Maugham had a good temperament for intelligence work; he believed that he had inherited from his lawyer father a gift for cool judgment and the ability to avoid being deceived by facile appearances.
