Question: The Lady and the Highwayman was based on a novel by which English author?

Neverwhere is the companion novelisation written by English author Neil Gaiman of the television serial "Neverwhere", by Gaiman and Lenny Henry.  The plot and characters are exactly the same as in the series, with the exception that the novel form allowed Gaiman to expand and elaborate on certain elements of the story and restore changes made in the televised version from his original plans.  Most notable is the appearance of the Floating Market at Harrods (in the novel) rather than under Battersea power station (the TV series).  This is because the management of Harrods changed their minds about proposed filming.  The novel was originally released by BBC Books in 1996, three episodes into the television series run.  It was accompanied by a spoken word CD and cassette release, also by the BBC.  The novel enjoyed great success, whereas its television roots did not receive as much international exposure as the novel.  In addition to being translated into various languages, it was also re-published as an 'Author's Preferred Text' version, (a combination of the international and original English version, with additional scenes re-inserted by Gaiman) alongside "American Gods" in 2006.  The original BBC Books version had a cover by longtime Gaiman collaborator Dave McKean, taken from the birds head rings, flaming fist and London Underground styled graphics created by McKean for the series, as well as a brief section by Gaiman on the making of the series. <SEP>  Her 723 novels were translated into 38 languages and she continues to be referenced in the "Guinness World Records" for the most novels published in a single year in 1976. Dame Mary Barbara Hamilton Cartland DBE CStJ (9 July 1901 – 21 May 2000) was an English author of romance novels, one of the best-selling authors as well as one of the most prolific and commercially successful worldwide of the twentieth century.  As Barbara Cartland she is known for her numerous romantic novels but she also wrote under her married name of Barbara McCorquodale and briefly under the pseudonym of Marcus Belfry.  She wrote more than 700 books, as well as plays, music, verse, drama, magazine articles and operetta, and was a prominent philanthropist.  She reportedly sold more than 750 million copies.  Other sources estimate her book sales at more than two billion copies.  She specialised in 19th-century Victorian era pure romance.  Her novels all featured portrait-style artwork, particularly the cover art, usually designed by Frances Marshall. <SEP> The Lady and the Highwayman is a 1989 United Kingdom romantic adventure TV movie based on Barbara Cartland's romance novel "Cupid Rides Pillion".  The working title of the film was "Dangerous Love". <SEP> Agnes Grey is the debut novel of English author Anne Brontë (writing under the pen name of Acton Bell), first published in December 1847, and republished in a second edition in 1850.  The novel follows Agnes Grey, a governess, as she works within families of the English gentry.  Scholarship and comments by Anne's sister Charlotte Brontë suggest the novel is largely based on Anne Brontë's own experiences as a governess for five years.  Like her sister Charlotte's novel "Jane Eyre", it addresses what the precarious position of governess entailed and how it affected a young woman.
