From the author of The Domino Principle: a weightless, nifty, likable melodrama which begins when Sen. Chet Treptow dies in the crash (or explosion?) of a new H-14 jet called Air Force Three (along with his family) and is replaced by his straight-talking, college-professor brother Gabe. With no plans for reelection, Gabe starts making a maverick splash in the senate a la Mr. Smith Goes to Washington--despite warnings and hatchet-jobs from his new colleagues. But then his attention (already diffused by grief over the death of his kinfolk and ex-wife miseries) is grabbed by investigative reporter R. M. Kosta, a serious, intense, breezily virginal gal who's convinced that the H-14 crash was really sabotage. In fact, the government itself may be involved in a conspiracy of silence! And above all, Kosta wants to know what happened to the extra body in the crash, one Ralph Benedict--why was his corpse cremated post haste? So Gabe and Kosta are soon a sleuthing team, engaging in splendid badinage every step of the way; and what they uncover involves an ousted oil sheik, secret US harboring of Shah-like relatives, and big-money bank dealings reminiscent of the current billion-dollar crises with Iran. Plot-wise, then: a foolish, contrived chunk of fluff. But Kosta is a dandy heroine in the Frank Capra/Jean Arthur tradition--and if you can agree to take none of this one bit seriously, you'll have an airily pleasing time.
