Cynthia Harrod-Eagles was born in Shepherd's Bush in London. She was educated at Burlington School, a girls' charity school founded in 1699, and at the University of Edinburgh and University College London, where she studied English, history and philosophy.
She wrote her first novel while at university and in 1972 won the Young Writers' Award with THE WAITING GAME.
Afterwards she had a variety of jobs in the commercial world, beginning as sales manager for the Coca Cola Company in Edinburgh, and ending up as pensions officer for the BBC in London, while writing during the evenings and weekends.
The birth of the MORLAND DYNASTY series enabled her to become a full-time writer in 1979. The series was originally intended to comprise twelve volumes, but it has proved so popular that it has now been extended to thirty-five.
In 1993 she won the RNA Novel of the Year Award with EMILY, the third volume of her Kirov Saga, a trilogy set in nineteenth century Russia, and she also writes the internationally acclaimed BILL SLIDER MYSTERIES.
Cynthia Harrod-Eagles still lives in London, has a husband and three children, and apart from writing her passions are music (she plays in several amateur orchestras) horses, wine, architecture and the English countryside.
