George Long is a former Roman Catholic priest--one of the many who are leaving their Church and, if current publishing trends may be so interpreted, rushing into print. All I Could Never He is an explanation of the former phenomenon and an illustration of the latter. The book comprises, for the most part, a rather Victorian-flowery account of the life-pattern that has already become familiar: family background, entry into the seminary, life in the seminary, ordination, life in the parish cum beastly pastor, self-emancipation from a life the strictures of which the author (any author) no longer was able to bear. Mr. Long's style is unsuited to his story; his dialogue is artificial and unrelievedly dull for pages on end; his story deja-vu with a vengeance. Despite those shortcomings, the book may be recommended to readers of Modern Screen, who will be titillated by the author's account of latter-day intimacy with the famous as ""John"" (Huston), ""Marilyn"" (Monroe), ""Elizabeth"" (Taylor) and ""Shirley"" (MacLaine) trudge, undulate, flirt, or flit through the pages. Other possible audiences are: the scandal-seekers (who will be disappointed), the sincerely concerned (who will be relieved of several of their illusions), and the curious (who will be unsatisfied).
