Inspector Paco and Molly, the endearing sleuths who fell in love in Locks and Cream Cheese, board a Vermilion Tours luxury bus for a blissful honeymoon out West. But conspirators and bank robbers sour their adventures through Yellowstone, Zion National Park, and the Grand Canyon. Each day dawns with a spine-chilling accident- on the Snake River; at Old Faithful; in a posh hotel bed. But are they accidents? The perils and pranks seem to target Ray Symington, a ruthless, womanizing corporate vice president, who is leading his salesmen and their wives on this tour. Fearing for his life, he turns to Paco and Molly for help. They'd rather smooch than sleuth. But when they themselves also become targets, they start 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?
