White Heat — Pamela Kent

Karin was thoroughly enjoying her cruise to Australia aboard the Ariadne, which a considerate employer, and hosts of admirers. The only fly in the ointment was the austere and arrogant Kent Willoughby, who made no secret of the fact that he had little time for women in general and Karin in particular. Karin decided that the best thing was to try and ignore him - and she managed fairly successfully until, following a fire aboard the Ariadne, she was shipwrecked on a desert island in the middle of the Indian Ocean with no one for company but Kent's manservant - and Kent himself.
