Prudence Eaton Seward

She trained as an engraver, then worked as a free-lance illustrator from 1951 to 1975.
Amongst many other books she illustrated: Rumer Godden: Candy Floss (Macmillan 1955); William Mayne: The Man from the North Pole (Hamilton, 1963) and On the Stepping Stones (Hamilton 1963).

Like many other free-lance illustrators, her work was often seen in the Radio Times, and it is here that we find the Saville connection. When the BBC repeated the radio serial of The Buckinghams at Ravenswyke, on the Northern Region in 1959 Malcolm Saville contributed a short article on the story and its setting to the Children's supplement. Hence we find, in the issue dated November 20th the article announcing the serial's first episode in Children's Hour on Saturday, and alongside the picture on the right. Oddly, she seems to have too many characters in the picture.

Juliet and Simon Buckingham and their friend Charles find the first clue to the mystery in an antique shop in Whitby.
