Ashenden by William Somerset Maugham

When Ashenden went on deck and saw before him a low-lying coast and a white town he felt a pleasant flutter of excitement. It was early and the sun had not long risen, but the sea was glassy and the sky was blue; it was warm already and one knew that the day would be sweltering. Vladivostok. It really gave one the sensation of being at the end of the world. It was a long journey that Ashenden had made from New York to San Francisco, across the Pacific in a Japanese boat to Yokohama, then from Tsuruki in a Russian boat, he the only Englishman on board, up the Sea of Japan. From Vladivostok he was to take the Trans-Siberian to Petrograd. It was the most important mission that he had ever had and he was pleased with the sense of responsibility that it gave him.

He had no one to give him orders, unlimited funds (he carried in a belt next to his skin bills of exchange for a sum so enormous that he was staggered when he thought of them), and though he had been set to do something that was beyond human possibility he did not know this and was prepared to set about his task with confidence. He believed in his own astuteness. Though he had both esteem and admiration for the sensibility of the human race, he had little respect for their intelligence: man has always found it easier to sacrifice his life than to learn the multiplication table.
