Happy with her husband-to-be and beloved son, Isabel Dalhousie has feelings about parenthood that grow more tender daily. So when Jane, a visiting academic adopted and sent to Australia as a baby, asks for help in tracing her Scottish origins, she cannot refuse. However, habitually upright Isabel finds herself beset by temptation - for instance, to be suspicious of Professor Lettuce`s latest subterfuge, and of her niece Cat`s weakness for the wrong man. And when the search for Jane`s parents turns troubling, she can hardly prevent herself from interfering too forcefully in family secrets. As she steers a course between love and laissez-faire, our philosopher heroine succeeds in resisting all temptations but those which must be answered, and teases a solution from every problem.
