Some 100 odd bridge problems make up a rather different type of bridge book, introduce and illustrate no particular system, and involve as well as a know ledge of the game - a definite deductive skill. The problems pose a key play or question and the solutions are frequently in story form- literary and historical characters engage in a colloquial dialogue to prove the point and enliven the lesson. Mr. Parson is a genial guide to the fine points of the game and is warmly introduced by John P. Marquand. A specialty.
