Ienjoy reading books very much and most of all i like the book of sherlock holmes stories by arthur conan doyle. the main characters of the stories are a brilliant detective sherlock holmes, who can solve the most complicated cases, and his loyal friend doctor john watson. sherlock holmes always pays attention to every detail and can expose the craftiest criminals. my favourite story is entitled “a scandal in bohemia”. in this story the king of bohemia visited sherlock holmes under an assumed name. he told sherlock that some years ago he had had an affair with an opera singer irene adler. the king was going to get married to a scandinavian princess and he was afraid that irene, who had compromising letters and photographs, could send them to his fiancée’s family. so he wanted sherlock to get them for him. finally, using disguise, holmes got into irene’s house and figured out where the photographs were hidden. but when he wanted to get them, the photographs were not in place. there was a letter from irene and her photograph. she unveiled his plans, but she promised not to use the photographs and letters against the king. so the famous detective was beaten by the clever woman.
