About Mary Wesley
Mary Aline Siepmann CBE, known by the pen name Mary Wesley, was an English novelist. During her career, she was one of Britain's most successful novelists, selling three million copies of her books, including ten bestsellers in the last twenty years of her life. Since her first adult novel was published only in 1983, when she was 71, she may be regarded as a late bloomer. In 1970 Wesley was left impoverished by the death of Siepmann, and it was only then that she became an author, turning to writing as a way to restore her finances.
