From shipwreck on a desert island, to the cloistered and exotic intrigues of the harem of a Turkish pasha, and a stately and secretive house in Cornwall, Rosetta finds her fate irrevocably linked to the lives of two men. Lucas Lorimer is attractive, worldly and cynical while Simon Perivale is a wanted man, a suspect in a much publicized murder case. By chance, they are country neighbors, and while visiting the crippled Lucas, Rosetta has the opportunity to prove Simon's innocence.
