情熱は嵐のあとで ; Caribbean Desire

From fictiondb: It was cold in the tropics.... And it seemed to get colder every time Conrad DeVere looked Emma Belle's way. The feeling was mutual. Emma thought Conrad was the most unlikable man she'd ever met. Conrad viewed Emma as a scheming gold digger--a woman who intended to use her position as researcher to Alistair Jackson to part the elderly millionaire from his money. Emma was prepared to live with Conrad's freezing contempt--he must never know the real reason she'd come to Tobago. But she wasn't prepared for the rush of jealousy that struck her when she learned of Conrad's engagement!
