searched through the cooler sitting between them on the seat. âAnyone feel like a sandwich? By some stroke of luck, we seem to have four sandwiches hereâthey all appear to be ham and cheese on dark bread with lettuce and pickles and stuff. In addition, thereâs cheese, piles of fruit, and things to drink. Coke?â he asked, passing out the wrapped sandwiches. âHere. And in the paper bag at your feet is the worldâs most enormous bag of cheezy things. Really, Harriet. I begin to doubt your taste and refinement. Also four boxes of crackers.â
âI was hungry,â she said. âSo I bought lots. Is it still cold?â
âVery,â said John. âAn extremely efficient cooler you have. Have a sandwich.â He unwrapped one and gave half to her.
âGorgeous. Hang on a minute, though, theyâre speeding up again, and the road is getting worse. I hope you kids donât get carsick.â
A muffled chorus from behind declared their immunity from such childish ailments.
And indeed, the van, admirable though it was for transporting large amounts of photographic equipment, was not designed for high-speed chases over bad roads, and at the moment it was rocking and bouncing like a small boat on a choppy sea. Suddenly, in a terrific crash of sound, the bus made a rapid right turn and disappeared from sight.
There was a worried exclamation from behind.
âIâm sorry,â said John, turning toward the backseat to hear better. âI didnât quite catch what you were saying.â
âWe said that heâs turned the wrong way.â Caroline was speaking softly, as if she were afraid to voice her concerns out loud. âOur regular driver never goes this way.â
âAnd he isnât the regular driver?â asked John.
âNo. The regular driverâs Bert, and Lesleyâs the regular guide on this kind of tour. Lesley does historic sites and Susie does desert flora and fauna. Thatâs plants and animals,â added Caroline politely, in case their traveling companions didnât have a scientific bent. âSomeone at Dallas said that Lesley was sick today, but Bert never gets sick. He always drives. Heâs nice. We really like Bert.â
Her brother nodded.
âI hope he isnât lost,â said Caroline. Her voice was carefully neutral. âI hope he drives past our road.â
âDonât be stupid, Carâof course heâll go past our road. Heâs just been heading around the city a different way.â Underneath his bravura tone Harriet heard the panic of a small child lost and far from home.
âOkayâwhat if we donât drive past your road?â interrupted Harriet. âLetâs consider the possibilities. What do we know? Two things. The bus driver is new, and the bus is leaving the cityâor has left the cityâvia a route unfamiliar to you. In these situations one begins, always, with the worst-case scenario. The new driver is just taking what he thinks is the best and most rapid route to Taos. Letâs say it doesnât intersect with your road. When we get to Taos, we call your parents, who will be very pleased to know youâre okay. Then we whisk you down to the hotel.â
âDo you work for the CIA?â asked Stuart. âYou sound a little like a CIA operative.â
âStuart asks everyone that,â said Caroline. âOur dad says he has a friend who works for the NSA, but he wonât tell us who it is, in case we drive him crazy.
âOr her. We love spy stories,â added Caroline.
Harriet shook her head. âIâm a photographer. Not nearly as exciting, is it?â
âA news photographer?â
âNo. I only photograph buildings. But I have a good friend whoâs a news photographer. Sheâs had pictures on the covers of
Time
and
Newsweek
,â she added. âDo you read magazines?â
âOf course we do,â said
