To this reader this book for the middle teens deserves attention on two specific counts:- one, that it is something of a relief to have the background and the cast of characters representative of the upper level, socially and economically, presented--, and a way of life other than the native peasant life shown as integral to Hawaii; two, that a psychological issue of a family situation is made of paramount importance, though the emotional values are superficial. Kay's father came from a four generation line of white settlers, plantation owners, living a luxurious life even though they had periods when agriculture and cattle raising suffered depressions. This story is set in just such a period, though the acute reason stemmed back to a manager who was indulging in shady doings to recoup his racing losses. Key's mother was a semi-invalid, who played up her invalidism to keep tight possession of her daughters. But in the course of this story, the oldest daughter breaks away-into matrimony; the third daughter has a chance to go to the States to study under a famous singer; and Kay, whose story this is- finds that she has mixed feelings about going on with her hoped-for study of landscape architecture in Switzerland; Hawaii, and a possible boy-interest in the offing, afford certain opportunities not to be ignored. The mystery of the title plays its part in helping solve the family problems, and a sometimes fortuitious succession of incidents brings new light on the mother's psychological twists. Kay has some quirks of her own that begin to unwind as the story gets under way.
