The roadworkers didn’t have the new exit signs up yet, and I missed the exit for Apache Junction and had to go halfway to Superior, trapped in my narrow, cement-sided lane, till I hit a change-lanes and could get turned around.

Katie’s address was in Superstition Estates, a development pushed up as close to the base of Superstition Mountain as it could get. I thought about what I would say to Katie when I got there. I had said maybe ten sentences altogether to her, most of them shouted directions, in the two hours we had been together. In the jeep on the way to the vet’s I had talked to Aberfan, and after we got there, sitting in the waiting room, we hadn’t talked at all.

It occurred to me that I might not recognize her. I didn’t really remember what she looked like—only the sunburned nose and that terrible openness, and now, fifteen years later, it seemed unlikely that she would have either of them. The Arizona sun would have taken care of the first, and she had gotten married and divorced, been fired, had who knows what else happen to her in fifteen years to close her face. In which case, there had been no-point in my driving all the way out here. But Mrs. Ambler had had an almost impenetrable public face, and you could still catch her off-guard. If you got her talking about the dogs. If she didn’t know she was being photographed.

Katie’s house was an old-style passive solar, with fat black panels on the roof. It looked presentable, but not compulsively neat. There wasn’t any grass—tankers won’t waste their credits coming this far out, and Apache Junction isn’t big enough to match the bribes and incentives of Phoenix or Tempe—but the front yard was laid out with alternating patches of black lava chips and prickly pear. The side yard had a parched-looking palo verde tree, and there was a cat tied to it. A little girl was playing under the tree with toy cars.
