NB: набросок анализа
Leslie Poles Hartley, an English novelist and the son of a solicitor was educated at Oxford's College and for more than twenty years he was a fiction viewer for magazines. He wrote many novels and made a good contribution to English fiction. According to his novels films were casted. Hartley was a highly skilled narrator and we can see that in his literary work "W.S.".
The main character of the story - Walter Streeter - gets one after the other four postcards with messages from anonymous and starts thinking them over. At first he was glad that he didn't have to answer them as a writer should grudge time and energy for that. He even tore the first two postcards away. But later it became so important for him that he pondered over this and nothing else. He avoided making new acquaintances and had many difficulties with his work over new book. He tried to write but the words came haltingly, as though contending with an extra-strong barrier of self-criticism. The third postcard wasn't burnt, Walter kept it. And only here it struck him that the initials of the postcard sender and his were the same. An idea came to Walter that perhaps he was writing those letters to himself. There were many questions and no answers. From the fourth postcard Walter found out that the sender was coming nearer and is eager to meet Walter. We can feel sympathetic attitude of the author towards Walter. A wave of panic surged up in Walter. And we can guess here Walter Streeter was afraid of that meeting. He'd like to avoid it, because he understood from the last postcards that W.S. wasn't satisfied with his last literary work. W.S. was saying he almost lived in those novels but he didn't like them any more.
Who was that W.S.? Taking all the facts into consideration we can say there wasn't anyone except Walter. And he - Walter had a split personality. He couldn't find all the shortcomings of his novels...
