Review title: The Eternal Triangle Again...with a Twist
Product review: Agatha Christie seems fascinated with the eternal love triangle plot (usually a husband, a wife, and a mistress); she uses it again and again in her books. Here we have a devoted couple; the husband is distracted by a grasping beauty, and murder ensues. Christie's handling of this theme is always sure-footed (possibly due to the breakup of her own first marriage due to a philandering husband); here she takes these commonplace elements and twists them to produce an end result that will lift the reader out of his chair. There are, perhaps, more exciting Christies, but this is quite satisfying and interesting. After all, the lady wrote a tremendous number of books and short stories; they can't all be her "best." See how many different variations on this theme Christie was capable of in "Five Little Pigs," "Death On the Nile," "Towards Zero," and "The Hollow," in which the triangle is more of a square, with four sides instead of three.
