It was a virtual copy of the Soleri-class arcology atriums that had spouted like mushrooms on the Earth in the last four decades, with the exception that on Earth you built up, and on Luna you went down.

First dig a trench fifteen miles long and two miles deep. Vary the width of the trench, but never let it get narrower than one mile, nor broader than five. In some places make the base of the trench wider than the top, so the walls of rock loom outward. Now put a roof over it, fill it with air, and start boring tunnels into the sides. Turn those tunnels into apartments and shops and everything else humans need in a city. You end up with dizzying vistas, endless terraces that reach higher than the eye can see, a madness of light and motion and spaces too wide to echo.

Do all that, and you still wouldn't have the Mozartplatz. To approach that ridiculous level of grandeur there were still a lot of details to attend to. Build four mile-high skyscrapers to use as table legs to support the mid-air golf course. Crisscross the open space with bridges having no visible means of support, and encrusted with shops and homes that cling like barnacles. Suspend apartment buildings from silver balloons that rise half the day and descend the other half, reachable only by glider. Put in a fountain with more water than Niagara, and a ski slope on a huge spiral ramp. Dig a ten-mile lake in the middle, with a bustling port at each end for the luxury ships that ply back and forth, attach runways to balconies so residents can fly to their front door, stud the interior with zeppelin ports and railway stations and hanging gardens... and you still don't have Mozartplatz, but you're getting closer.

The upper, older parts of New Dresden, the parts she had grown up in, were spartan and claustrophobic. Long before her time Lunarians had begun to build larger when they could afford it.

The newer, lower parts of the city were studded with downscale versions of the Mozartplatz, open spaces half a mile wide and maybe fifty levels deep. This was just a logical extension.

She felt she ought to dislike it because it was so overdone, so fantastically huge, such a waste of space... and, oddly, so standardized. It was a taste of the culture of old Earth, where Paris looked just like Tokyo. She had been to the new Beethovenplatz at Clavius, and it looked just like this place. Six more arco-malls were being built in other Lunar cities.

And Bach liked it. She couldn't help herself. One day she'd like to live here.

She left her tube capsule in the bustling central station, went to a terminal and queried the location of the Great Northern. It was docked at the southern port, five miles away.

It was claimed that any form of non-animal transportation humans had ever used was available in the Mozartplatz. Bach didn't doubt it. She had tried most of them. But when she had a little time, as she did today, she liked to walk. She didn't have time to walk five miles, but compromised by walking to the trolley station a mile away.

Starting out on a brick walkway, she moved to cool marble, then over a glass bridge with lights flashing down inside. This took her to a boardwalk, then down to a beach where machines made fourfoot breakers, each carrying a new load of surfers. The sand was fine and hot between her toes.

Mozartplatz was a sensual delight for the feet. Few Lunarians ever wore shoes, and they could walk all day through old New Dresden and feel nothing but different types of carpeting and composition flooring.

The one thing Bach didn't like about the place was the weather. She thought it was needless, preposterous, and inconvenient. It began to rain and, as usual, caught her off guard. She hurried to a shelter where, for a tenthMark, she rented an umbrella, but it was too late for her paper uniform. As she stood in front of a blower, drying off, she wadded it up and threw it away, then hurried to catch the trolley, nude but for her creaking leather equipment belt and police cap. Even this stripped down, she was more dressed than a quarter of the people around her.

The conductor gave her a paper mat to put on the artificial leather seat. There were cut flowers in crystal vases attached to the sides of the car. Bach sat by an open window and leaned one arm outside in the cool breeze, watching the passing scenery. She craned her neck when the Graf Zeppelin muttered by overhead. They said it was an exact copy of the first world-girdling dirigible, and she had no reason to doubt it.

It was a great day to be traveling. If not for one thing, it would be perfect. Her mind kept coming back to Charlie and her mother.

She had forgotten just how big the Great Northern was. She stopped twice on her way down the long dock to board it, once to buy a lime sherbet ice cream cone, and again to purchase a skirt. As she fed coins into the clothing machine, she looked at the great metal wall of the ship. It was painted white, trimmed in gold. There were five smokestacks and six towering masts. Midships was the housing for the huge paddlewheel. Multi-colored pennants snapped in the breeze from the forest of rigging. It was quite a boat.

She finished her cone, punched in her size, then selected a simple above-the-knee skirt in a gaudy print of tropical fruit and palm trees. The machine hummed as it cut the paper to size, hemmed it and strengthened the waist with elastic, then rolled it out into her hand. She held it up against herself. It was good, but the equipment belt spoiled it.

There were lockers along the deck. She used yet another coin to rent one. In it went the belt and cap.

She took the pin out of her hair and shook it down around her shoulders, fussed with it for a moment, then decided it would have to do. She fastened the skirt with its single button, wearing it low on her hips, south-seas style. She walked a few steps, studying the effect. The skirt tended to leave one leg bare when she walked, which felt right.

"Look at you," she chided herself, under her breath. "You think you look all right to meet a worldsfamous, glamorous tube personality? Who you happen to despise?" She thought about reclaiming her belt, then decided that would be foolish. The fact was it was a glorious day, a beautiful ship, and she was feeling more alive than she had in months.

She climbed the gangplank and was met at the top by a man in an outlandish uniform. It was all white, covered everything but his face, and was festooned with gold braid and black buttons. It looked hideously uncomfortable, but he didn't seem to mind it. That was one of the odd things about Mozartplatz. In jobs at places like the Great Northern, people often worked in period costumes, though it meant wearing shoes or things even more grotesque. He made a small bow and tipped his hat, then offered her a hibiscus, which he helped her pin in her hair. She smiled at him. Bach was a sucker for that kind of treatment—and knew it—perhaps because she got so little of it.

"I'm meeting someone in the bar on the top deck."

"If madame would walk this way..." He gestured, then led her along the side rail toward the stern of the ship. The deck underfoot was gleaming, polished teak.

She was shown to a wicker table near the rail. The steward held the chair out for her, and took her order. She relaxed, looking up at the vast reaches of the arco-mall, feeling the bright sunlight washing over her body, smelling the salt water, hearing the lap of waves against wood pilings. The air was full of bright balloons, gliders, putt-putting nano-lights, and people in muscle-powered flight harnesses. Not too far away, a fish broke the surface. She grinned at it.

Her drink arrived, with sprigs of mint and several straws and a tiny parasol. It was good. She looked around. There were only a few people out here on the deck. One couple was dressed in full period costume, but the rest looked normal enough. She settled on one guy sitting alone across the deck. He had a good pair of shoulders on him. When she caught his eye, she made a hand signal that meant "I might be available." He ignored it, which annoyed her for a while, until he was joined by a tiny woman who couldn't have been five feet tall. She shrugged. No accounting for taste.
