Inspector Paco and his new bride board a luxury bus tour for a blissful honeymoon out West. But conspirators and bank robbers sour their adventures through Yellowstone, Zion National Park, and the Grand Canyon. Not a day dawns without a spine-chilling accident—on the Snake River; at Old Faithful; in a posh hotel. But are they accidents? The perils and pranks seem to target Ray Symington, a ruthless, womanizing corporate vice president, who is leading his top salesmen and their wives on this tour. Fearing for his life, Ray turns to Inspector Paco and Molly. They'd rather smooch than sleuth. But when they themselves—and other fellow travelers also become victims, they strat digging and uncover murderous schemes as spectacular as the Rockies and Lake Powell. They want to stop the attacks. But will they be too late?
