After her aunt's death, Thea gladly gives up her dreary job in the suburbs to travel to the island of Biscany. She is sure she will be looked after there by handsome Bevil Royce, with whom she had had such as passionate love affair during his stay in London. But the pretty but penniless little typist had been merely a temporary whim of the worldly Bevil - and now he is engaged to the chic daughter of a wealthy and influential baronet. Then, through a strange act of fate, Thea finds herself under the protection of the new Governor of the Island. Charles Fettermore is a deeply embittered man who has his own reasons for wanting revenge on Bevil Royce. As she becomes the focus of a deadly rivalry between the two men, Thea realises that she will have to make a vital choice... She had been cruelly cheated by the man she loved - and now she would have her revenge.
