'"Radcliffe published five novels during her lifetime, which she always referred to as "romances"; a final novel, "Gaston de Blondeville" was published posthumously in 1826.At a time when the average amount earned by an author for a manuscript was £10, her publishers, G. G. and J. Robinson, bought the copyright for "The Mysteries of Udolpho" (1794) for £500, while Cadell and Davies paid £800 for "The Italian" (1797), making Radcliffe the highest-paid professional writer of the 1790s.
