Among her works were
The Romance of the Pyrenees (1803),
The Forest of Montalbano (1810),
Adelaide; or, The Countercharm (1813), ''Rosabella, or A Mother's Marriage
(1817), The Hut and the Castle: a Romance
(1823), and Sir Ethelbert; or, the Dissolution of Monasteries
(1830). At least one, Santo Sebastiano
(1806), was published twice in penny instalments, as The Heiress of Montalvan, or First and Second Love
(1845–46) and as Santo Sebastiano, or The Heiress of Montalvan'' (1847–48). Cuthbertson has been described by present-day scholars as a "fairly conventional novelist" using "historically realised settings (often in continental Europe)" with "happy endings". Her upper-class characters appear virtuous, her lower-class ones comic or occasionally horrific. A recent anthologist puts her among "the best of the
Radcliffe imitators."
Romance of the Pyrenees was serialized in the ''Lady's Magazine
, starting in February 1804, but not in book form, "probably because the expected second sale did not warrant the cost." It took three years and "is the longest novel ever published in an eighteenth-century miscellany, with the single exception of Pamela''." The work was also translated into French, but attributed there to Radcliffe, ==Bibliography==
