Dorothy Kathleen Broster (1877 - 1950) produced 15 popular historical novels between 1911 and 1947. The Yellow Poppy (1920) about the adventures of an aristocratic couple during the French Revolution, was later adapted by Broster and W. Edward Stirling for the London stage in 1922. She produced her bestseller Scottish historical novel, The Flight of the Heron, in 1925. Broster stated she had consulted eighty reference books before beginning the novel. She followed it up with two successful sequels, The Gleam in the North and The Dark Mile. She wrote several other historical novels, successful and much reprinted in their day, although this Jacobite trilogy (inspired by a five-week visit to friends in Scotland), featuring the dashing hero Ewen Cameron, remains the best known. The Flight of the Heron was adapted for BBC Radio twice, in 1944, starring Gordon Jackson as Ewen Cameron, and again in 1959, starring Bryden Murdoch as Cameron. Murdoch also starred in radio adaptations of the book's sequels, The Gleam in the North and The Dark Mile.
