Ashenden by William Somerset Maugham

When Ashenden found himself in his bedroom at the hotel and, for the first time for it seemed an age, alone he sat down and looked about him. He had not the energy to start immediately to unpack. How many of these hotel bedrooms had he known since the beginning of the war, grand or shabby, in one place and one land after another! It seemed to him that he had been living in his luggage for as long as he could remember. He was weary. He asked himself how he was going to set about the work that he had been sent to do. He felt lost in the immensity of Russia and very solitary. He had protested when he was chosen for this mission, it looked too large an order, but his protests were ignored. He was chosen not because those in authority thought him particularly suited for the job, but because there was no one to be found who was more suited. There was a knock at the door and Ashenden, pleased to make use of the few words of the language he knew, called out in Russian. The door was opened.

He sprang to his feet.
