As he stepped forward to the open window, Carter could feel the cool air of the inside of the car on his face; could smell the sweet smokiness of new leather and then, closer still, the scent of the woman’s perfume. She was leaning toward the passenger window, her body straining against her seat belt, sunglasses perched on top of her head. A white woman, of course. He’d known that even before he looked. The black Denali with its shining paint job and huge gleaming grille. The eastbound lane on San Felipe, connecting the Galleria with River Oaks, where the big houses were. The woman was young, though, younger than he would have thought for a car like that, thirty at the most, and wearing what looked like tennis clothes, a white skirt and top that matched, her skin moist and shining. Her arms were lean and strong and coppered by the sun. Straight hair, blond with streaks of a darker color, pulled back from the planes of her face, her delicate nose and well-cut cheekbones. No jewelry he could see except a ring, a diamond fat as a tooth. He knew he shouldn’t look any closer, but he couldn’t stop himself; he let his eyes skim through the back of the car. He saw a baby seat, empty, with brightly colored plush toys hanging over it and beside it a large shopping bag that was made of paper but looked like metal. The name of the store, Nordstrom, was written on the bag.

“Whatever you can give,” Carter muttered. “God bless you.”

Her purse, a fat leather satchel, was resting on her lap. She began tossing the contents out onto the seat: a tube of lipstick, an address book, a tiny, jewel-like phone. “I want to give you something,” she was saying. “Would a twenty be enough? Is that what people do? I don’t know.”

“God bless you now.” The light, Carter knew, was about to change. “Whatever you can do.”

She withdrew her wallet just as, behind them, they heard the first impatient honk. The woman turned her head quickly at the sound, then looked up at the traffic signal, now green. “Oh, damnit, damnit.” She was frantically riffling through the wallet, a huge thing the size of a book, with snaps and zippers and compartments crammed with slips of paper. “I don’t know,” she was saying, “I don’t know.”

More honking, and then, with a roar, the vehicle behind her, a red Mercedes, accelerated to jam itself across the middle lane, cutting off an SUV. The driver of the SUV slammed on his brakes and leaned on his horn.

“I’m sorry, I’m sorry,” the woman kept saying. She was looking at the wallet like it was a locked door she couldn’t find the key to open. “It’s all plastic in here, I thought I had a twenty, maybe it was a ten, oh goddamnit, goddamnit … ”
