As a girl, she constantly experimented with writing. In 1849 she had her first novel published: Passages in the Life of Mrs. Margaret Maitland which dealt with the Scottish Free Church movement. It was followed by Caleb Field in 1851, the year in which she met the publisher William Blackwood in Edinburgh and was invited to contribute to the famous Blackwood's Magazine. The connection was to last for her whole lifetime, during which she contributed well over 100 articles, including, a critique of the character of Arthur Dimmesdale in Nathaniel Hawthorne's The Scarlet Letter.
