Joseph McAleer in his book Passion's Fortune: The Story of Mills and Boon, describes Brett's work as so sexy for the era, that it often had to be "watered down".
Rosalind Brett's romances from the 1950s are historically significant for the Mills & Boon series, by her choice of locations.
Her stories take readers away from the British Isles, to East Africa: Rhodesia, Nyasaland, providing glimpses of Salisbury (present day Harare) and Bulawayo, the second city in what is now Zimbabwe.
The main characters are at work trying to build prosperous lives in what were British, French and Portuguese colonies.
Publishing in post World War II period, Brett writes at the crossroads of history when, colonial rule once paramount in parts of Africa, Asia and the Pacific, would come to be challenged.
