Title: The Sea Change
Subtitle: Doctor Overboard
Description: When Mairi Finlay's boss, the wealthy mill-owner Sir Oliver Bligh, offered her the chance of a cruise to the Caribbean on a luxury steamer, all expences paid, she was naturally delighted. But of course there was more to it than that. The whole purpose of the trip was that Mairi should keep a watchful eye on Sir Oliver's daughter Caroline, who was infatuated with the fortune-hunting Geoffrey Quinnel. It was alarming to discover, shortly after the cruise got under way, that Geoffrey had managed to get himself on board too - and by that time Mairi had problems of her own when she became attracted to the ship's doctor, David Rodney. What with one thing and another, it did not look as if Mairi would have much time for romance - especially as David showed little sign of returning her feelings!
