Working for Professor Sam Gervis was difficult enough, even if you hadn't fallen in love with him. But Polly had. Luckily she was realistic. Sam was engaged to the lovely Deirdre, and besides, he would never look twice at anyone as quiet and mousy as her. So Polly sensibly decided to get away and take up a new career nursing children. But she soon discovered that Sam wasn't a man to be escaped from easily.
