The fourth in a series (The Sooner Spy, 1990, etc.) about delightful one-eyed Mack--the zany, boyish, innocent Lieutenant Governor of Oklahoma--who in this novel goes through the mildest midlife crisis ever to be committed to paper. At the opening, our man Mack is refereeing a Turnpike Squabble precipitated by the promise of his boss, Governor Buffalo Joe, to two rich constituents that he would build a four-lane road in each constituent's county, and the state legislature's corresponding determination that no four-lane road at all will appear. Then, without warning, Joe's foremost adversary on the issue, the Speaker of the State House of Representatives, a man named Luther Wallace, simply vanishes from home and office. Kidnapped? Murdered? Mack is determined to find out. With aid from his pal C., director of the Oklahoma Bureau of Investigation, he does: Luther has run away. Dispatched by Luther's wife, Mack heads out to France, where he finds Luther and four other wacky country characters reliving their common heyday in the 50's as Marines. Meanwhile, Mack is also investigating an accident that has killed a Continental Trailways bus driver and 24 passengers on the Red River Bridge that separates Texas from Oklahoma; clues to that mystery and to Luther's weird behavior feed into one another, until the notion of middle age--including Mack's own--provides the key to both. Mack uses his accumulated wisdom to squelch all talk of turnpikes. The result is a slight but very pleasant read.
