the world of literature is very various. there are lots of different writers who create different kinds of books. my favourite style is a detective story. i like to read exciting stories about mystic crimes, clever detectives and artful criminals. so it`s not surprising that my favourite writer is agatha christie. her books are always very interesting. me favourite character is hercule poirot. he is very intelligent and keen that`s why he can solve any riddle. i think that agatha christie is the queen of crime as her language is simple and her crimes are not bloody but very intricate. i never can guess the murdere till i finish the book. some days ago i started to raed "death on the nile" and i enjoy this book very much. i advise you to read agatha christie too.
