The Island Mystery

Diana Rayner certainly had her hands full! Not only was she a successful and well-known young concert pianist, she was also the oldest of the four Rayner sisters. She had to plan their daily lives, sympathize with them in their joys and sorrows, discipline them when they became too unruly - in short, she had to be mother and father rolled into one. When her temperamental younger sister Christine is persuaded to spend a holiday away from the girls on a small island which had been left to her by the mysterious Robert Greystones, the whole family's life changes.
