                                            Create a realistic portrait of a British novelist, Margaret Elinor Belsham, also known as Margaret Yorke, in a setting that reflects her profession as a crime fiction writer, perhaps with a subtle hint of mystery or suspense, sitting at a desk with papers and a pen, in a style that is reminiscent of a 20th-century literary figure, with a focus on capturing her personality and essence as a renowned author of works such as the Patrick Grant series and "No Medals for the Major", a recipient of the prestigious Crime Writers' Association Cartier Diamond Dagger award.
