Supersonic agents, Harrigan and Hoeffler, take the trail from San Francisco to Taos to Mexico for the why of possible Russian reactivation in abducting a top scientist. Pulling fast art dodges, faster footwork on those they are tracking, using newer than new devices, the pair collects -- and corrects -- the information needed, breaks up the Russian core, and keeps the scientist for home use only. Giddy and gaudy.
