“Have you ever used one of these stairways?”

Instead of replying, the driver directed a faint smile toward his rearview mirror, a smile that could be read any number of ways.

“It’s strictly up to you,” he said, tapping lightly on the steering wheel in time to the music. “If you just want to sit here and relax and enjoy the music, I’m fine with that. We might as well resign ourselves to the fact that we’re not going anywhere soon. All I’m saying is that there are emergency measures you can take if you have urgent business.”

Aomame frowned and glanced at her watch. She looked up and studied the surrounding cars. On the right was a black Mitsubishi Pajero wagon with a thin layer of white dust. A bored-looking young man in the front passenger seat was smoking a cigarette with his window open. He had long hair, a tanned face, and wore a dark red windbreaker. The car’s luggage compartment was filled with a number of worn surfboards. In front of him was a gray Saab 900, its dark-tinted windows closed tight, preventing any glimpse of who might be inside. The body was so immaculately polished, you could probably see your face in it.

The car ahead was a red Suzuki Alto with a Nerima Ward license plate and a dented bumper. A young mother sat gripping the wheel. Her small child was standing on the seat next to her, moving back and forth to dispel its boredom. The mother’s annoyance showed on her face as she cautioned the child to keep still. Aomame could see her mouth moving. The scene was unchanged from ten minutes earlier. In those ten minutes, the car had probably advanced less than ten yards.

Aomame thought hard, arranging everything in order of priority. She needed hardly any time to reach a conclusion. As if to coincide with this, the final movement of the Janáček was just beginning.
