The moderate success of recent novels with Scriptural backgrounds and characters (Mary of Nazareth, for instance) has resulted in several that drew the long bow in the adaptation of fact. This, however, has little or no known fact to go on, but the author has succeeded in establishing a feeling of sincerity, of sound psychological backing, so that one feels ""This is the way it might have been. This is the way Joseph would have felt."" And it is quite charming, though slight both in substance and length. It could offend no one, in its traditional interpretation of the virgin birth. Limited market -- but in certain circles might have a good Christmas gift book sale.
