Except the last one. She had been standing right in front of the eisenstadt, looking almost directly into the lens. “When I think of that poor thing, all alone,” she had said, and by the time she turned around she had her public face back on, but for a minute there, looking at what she thought was a briefcase and remembering, there she was, the person I had tried all morning to get a picture of.

I took it into the living room and sat down and looked at it awhile.

“So you knew this Katherine Powell in Colorado,” Ramirez said, breaking in without preamble, and the highwire slid silently forward and began to print out the lifeline. “I always suspected you of having some deep dark secret in your past. Is she the reason you moved to Phoenix?”

I was watching the highwire advance the paper. Katherine Powell, 4628 Dutchman Drive, Apache Junction. Forty miles away.

“Holy Mother, you were really cradle-robbing. According to my calculations, she was seventeen when you lived there.”

Sixteen.

“Are you the owner of the dog?” the vet had asked her, his face slackening into pity when he saw how young she was.

“No,” she said. “I’m the one who hit him.”

“My God,” he said. “How old are you?”

“Sixteen,” she said, and her face was wide open. “I just got my license.”

“Aren’t you even going to tell me what she has to do with this Winnebago thing?” Ramirez said.

“I moved down here to get away from the snow,” I said, and cut out without saying goodbye.

The lifeline was still rolling silently forward. Hacker at Hewlett-Packard. Fired in ninety-nine, probably during the unionization. Divorced. Two kids. She had moved to Arizona five years after I did. Management programmer for Toshiba. Arizona driver’s license.

I went back to the developer and looked at the picture of Mrs. Ambler. I had said dogs never came through. That wasn’t true. Taco wasn’t in the blurry snapshots Mrs. Ambler had been so anxious to show me, in the stories she had been so anxious to tell. But she was in this picture, reflected in the pain and love and loss on Mrs. Ambler’s face. I could see her plain as day, perched on the arm of the driver’s seat, barking impatiently when the light turned green.
