In the publishing business, as is well known, timing is all--almost. Thus, what now is merely a fairly good book would have been, a decade ago, a very brave and important one. Senator Potter (R., Michigan) was a member of the Government Operations Committee, better known as the ""McCarthy Committee,"" during the days which climaxed in the Army hearings and the Junior Senator from Wisconsin's trial and sel-execution By nationwide TV. Despite the fact that all this material has been reworked many times by now, there are several valuable and quite new insights offered here. Also, the author does not absolve himself or many of his colleagues of partial responsibility. And certainly he is right when he states that ""It was never only McCarthy. And, in the years since Joe died, the same abuses have gone on, many of them without ever being spot, lighted in the press."" However, in the all-essential matter of motivations for the fantastic Cohn and Schine routine, Potter is just as scanty with helpful suggestions as most of his predecessors. Then, too, his emotionalism is at times off-key; was this really ""the tragedy of a man who had plunged too boldly and alone into the dangerous Jungle""? Many would sooner agree that McCarthy was one of the nastier dangers in that jungle.
