As nearly as we could determine between the points, hither, thither and whither our mind was wandering, this is very little science and very little fiction by an author who has done a great deal under that umbrella of the sky. Reduced from some 416 pages to a few lines, it's about Johann Sebastian Bach Smith, a brilliant mind in an aged and shot body, who arranges to have his brain Transplanted into the nubile chassis of his secretary Eunice. A successful operation. Then followed by much about Johann and Eunice and Johann-Eunice-Us, with fallout on the legalistic problems which ensue; on Joe, Eunice's artist-husband; and on the marriage of the combined character to the brain's deputy-manager. . . . You could call it one of those surgical spare parts novels which immediately summons up the dreadful dual legacy of Christine-Christiaan Barnard.
