помогите пожалуйста! переведите текст на русский язык... Whatever Happened to Uncle Oscar?
----------" текст ниже "-------

At about ten - thirty, Aunt Agatha got a telephone call from the bank. " Where is your husband, Mrs Leighton?" asked the bank manager. Aunt Agatha was very much surprised. " Isn't he in the bank?" she asked. " No, he isn't. Wherever he is, he is not certainly in his offce," the bank manager answered. " Nobody has seen him yet. We are going to have a meeting in a quarter of an hour. But unfortunately we can't have it without your husband. He has all the papers." " I don't know what to say," Aunt Agatha tried to be polite. Well, that was it. No news from Uncle Oscar. Life went on. Elizabeth soon married and Julian got a good jod as an engineer. Aunt Agatha took a job in the office and enjoyed it. She saw her childrenat weekends. They seldom spoke about Uncle Oscar. They thought he was dead. I think only one person missed him —- me. We both had one hobby —- collecting stamps. I often thought of my uncle and tried to guess where he could be. Three years passed. And then one October afternoon a letter came. It arrived from Brazil. I was sure I knew no one in Brazil. I opened the envelope. There were some stamps inside. I counted them. There were about fifty stamps there, all Brazilian, nothing more. I turned the envelope over, but there was no return address. I took one of Uncle Oscar's albums of stamps from the shelf and opened it. I wanted to put the new stamps in it. Suddenly my eyes fell on several empty places in the book. The most expensive stamps were gone. Then I understood everything. I smiled. I knew now where Uncle Oscar was. I was sure he missed me, he missed our talks about stamps and collections and he discovered a way to tell me where he was. That was his secret and it will be his secret. I will tell nobody.
