Meg and Cathie MacRae were identical twins, and as close as such twins usually are but in character they were quite different - and so, luckily were their tastes. Although they worked together in the same hospital, and met the same set of people, they had so far never managed to fall for the same man. So far... but now Sandy Carmichael was in the picture, and for the first time Meg and Cathie had a problem on their hands. Meg was the first to admit Sandy's attraction, so that when Cathie found herself feeling much the same way, she felt she had no right to poach on her sister's preserves. But both of them had left Sandy himself out of their calculations. He took them both out, and was one of the few people who could tell them apart, which presupposed a particular interest in one of them. Which one...?
