She taught in schools in both
Indianapolis and
Chicago. She wrote for the
Chicago Tribune as a
stunt girl reporter under the
pseudonym "Nora Marks" from 1888 to 1890, and later became publisher of the
Little Chronicle Publishing Company, Chicago; this published several of her own works, along with other educational books and the
Little Chronicle, an
illustrated newspaper intended for young children. While she wrote both fiction and non-fiction, the former mostly romances and the latter mostly educational books, she is best known for her 1912 novel
Greyfriars Bobby. This popular work recounted the famous story of
the eponymous dog; most of the modern versions of the story seem to stem from her form of the tale. Many details of the book, especially those regarding the dog's master are inaccurate; until recently it was assumed that she had no opportunity for original research of her setting. It seems likely that she worked from the basic story and embellished it from her own imagination. The story, however,
is lovingly detailed; the descriptions of the geography may be somewhat confused, but effort was clearly made to get names correct, and to get across the atmosphere of the city. Unusually for someone with no connection to the country, her portrayal of the local accent was convincing and strongly phrased; this suggests it is possible she picked up the story directly from Scottish immigrants to the Midwest. : ''"I wullna gang to the infairmary. It's juist for puir toon bodies that are aye ailin' an' deein'." Fright and resentment lent the silent old man an astonishing eloquence for the moment. "Ye wadna gang to the infairmary yer ainsel', an' tak' charity."'' The book is often considered a classic, especially for children, and has been reprinted several times; it was the basis for the films
Challenge to Lassie (
MGM, 1949) and
Greyfriars Bobby (
Disney, 1961), although both of these postdated her death. Both films starred
Donald Crisp. ==Personal life==
