Frost waited for the cable car to pass, and then he crossed into Union Square. He finished a foot-long hot dog as he walked. Ketchup, pickle relish, no onions. It drove his brother crazy that Frost ate so many hot dogs. Duane was a chef, and he didn’t appreciate Frost’s argument that street-vendor hot dogs were better than just about any other food in the world.

The sun beat down on his neck. Entering the plaza, he passed under the palm trees. The Macy’s building was across the square on his right. People swarmed the park, clustering around musicians, mimes, jugglers, and acrobats. Above the street music, he heard the chants and drums of protesters, and he could see hand-painted signs waving in the air. It was San Francisco. Someone was always protesting something.

He found the terraced steps leading down to Geary Street, and it took him a minute to spot Lucy Hagen among the hundred-or-so people eating lunch on the steps on the warm afternoon. She was small and alone, watching the world go by with a dreamy expression on her face. She wore a belted red dress with black stripes at the hem. Her knees were pressed together, and she wore red high heels. The dress showed off her pretty arms and legs. Her brown hair nestled on her shoulders.

He squeezed his way down the steps and slid to the ground beside her. He whistled a tune that had been stuck in his head all day.

“Hey, Lucy,” he said.

“Oh, hey, Frost.” She welcomed him with a smile.

“Sorry to interrupt your lunch break, but I had a few more questions for you.”

“That’s okay. I like the company.”

Her lunch consisted of a couscous salad with olives and artichoke hearts. She took dainty, uninterested bites with a plastic fork. He guessed that if he’d offered to buy her a hot dog, she would have jumped at the chance.

“You look great,” he said.

“Have to look good for the Macy’s customers, you know.” But he could tell she was pleased with the compliment.

Lucy always looked a little lost when he saw her. Some single women owned the city, and some looked overwhelmed by it. Her big, curious eyes followed the people around her. She was a watcher, not a doer. He had the feeling that she stared at other San Franciscans on the street and wondered how they could make it look so easy. The businessmen. The construction workers in bright yellow. The drag queens. Even the homeless wrapped in blankets.

She noticed him studying her face and went back to her lunch in embarrassment. Her mouth twitched into a frown. “Have they found Brynn’s body yet?”

“No.”

Lucy shivered. “That’s awful.”

“It is. I’m sorry.”

“I checked with her supervisor, by the way. Brynn missed a day of work this week. She didn’t show up. She didn’t call.”
