The Last Call by George Wier
Summary: Bill Travis, an unmarried, unattached investment counselor rapidly approaching his fortieth birthday, conceives that he may not live the most exciting of lives, yet Julie Simmons, his first appointment that Monday, is deeply in trouble. She has taken a North Texas quarter horse racer and liquor baron named Archie Carpin–the last of a dynasty of criminals from the 1920’s–for a ride and cleaned him out of a neat two million bucks. And thus begins the adventure of Bill’s life.
Ensues a chase north across Texas to recover the money and shake the pursuit of a couple of rednecks with a penchant for rifles and rigged explosives. Yet, through all this action the compelling tale of yet another mystery—an 80-year old missing person’s case—begins to unravel.
