Tidal Wave — Jean S. MacLeod

"My father is missing and I'm her to do something about it."

But Nicholas Durham, her father's partner, seemed less than enthusiastic about Elizabeth's sudden arrival on the tropical island of Tamarind. In fact she got the distinct impression that the would have preferred her to stay in London and leave him to solve the mystery of Josh Conway's strange disappearance! Not that she cared what Nicholas thought about her: he might be successful, attractive and the most eligible bachelor around, but as far as Elizabeth was concerned the glamorous Lydia was entirely welcome to stake a claim to him!

Hero: Nicholas Durham
Heroine: Elizabeth Conway
