After leaving university, Cynthia had a variety of jobs in the commercial world, beginning as sales manager for the Coca-Cola Company in Edinburgh, and ending as pensions officer for the BBC in London.
In addition to writing, her interests are, horses, wine, architecture, the English countryside, and music: she plays in several amateur orchestras.
The plan was for the whole run of British history from the Middle Ages to the Second World War to be covered in twelve volumes (Harrod-Eagles' initial contract was for just four books).
Cynthia Harrod-Eagles admits the first novel in the Bill Slider series was written for relaxation and was never intended for publication.
However it received good reviews, being praised for its "nicely detailed prose" and "approachable characters" (Klett 1992:181) and as a "masterful debut" (Brainard 1992b:51).
