Виктория Холт - The Black Opal

Abandoned as a baby, her exotic beauty prompted hushed whispers of gypsy blood. But lovely Carmel March remained shrouded in mystery….
When tragedy struck her adopted home of Commonwood House, little Carmel had been bundled off to Australia. Returning to England as a young woman, she became haunted by questions from her past, as well as the shocking revelation that she had been rushed from a murder scene those many years ago.
Yet she was convinced that the wrong man had been sentenced for the crime. Was the answer locked away in her childhood memory — or in the dark, secretive behavior of her old childhood friend, Lucian? And what fateful role did the opals — always present at crucial moments of her life — play? For only when she released the dark secrets imprisoned at Commonwood would she find the freedom to love.
