Weil's silly-looking riddle monster turns out to be none other than the Sphinx of Greek legend, though only those who know the story will identify the nameless prince who finally solves the riddle as Oedipus. The prince's anonymity is as it should be in a simple picture story, though one might ask for a note fore or aft identifying the story's source--Weil's audience is left to infer it from the Greek buildings and garb in her pictures. And one does long for a more imposing Sphinx. Nevertheless the story lends itself well to picture-book treatment, and Weil knows just how to tell it, verbally and visually, for this audience. The narrative value of the story and the clever ham acting of Weil's pictures make this a reliable crowd-pleaser and attention-holder.
