His radio crackled to life on the outside channel, McDowell’s voice filling his helmet. “Jim? We may have a problem.”

Miller was halfway through his evening meal when the system in his hole chirped. He glanced at the sending code. The Blue Frog. It was a port bar catering to the constant extra million noncitizens of Ceres that advertised itself as a near-exact replica of a famous Earth bar in Mumbai, only with licensed prostitutes and legal drugs. Miller took another forkful of fungal beans and vat-grown rice and debated whether to accept connection.

Should have seen this one coming,he thought.

“What?” he asked.

A screen popped open. Hasini, the assistant manager, was a dark-skinned man with eyes the color of ice. The near smirk on his face was the result of nerve damage. Miller had done him a favor when Hasini had had the poor judgment to take pity on an unlicensed prostitute. Since then, security detective and portside barman had traded favors. The unofficial, gray economics of civilization.

“Your partner’s here again,” Hasini said over the pulse and wail of bhangra music. “I think he’s having a bad night. Should I keep serving him?”

“Yeah,” Miller said. “Keep him happy for… Give me twenty minutes.”

“He doesn’t want to be kept happy. He very much wants a reason to get unhappy.”

“Make it hard to find. I’ll be there.”

Hasini nodded, smirking his damaged smirk, and dropped the connection. Miller looked at his half-eaten meal, sighed, and shoved the remains into the recycling bin. He pulled on a clean shirt, then hesitated. The Blue Frog was always warmer than he liked, and he hated wearing a jacket. Instead, he put a compact plastic pistol in his ankle holster. Not as fast a draw, but if it got that far, he was screwed anyway.

Ceres at night was indistinguishable from Ceres in the daytime. There had been a move, back when the station first opened, to dim and brighten the lights through the traditional human twenty-four-hour cycle, mimicking the spin of Earth. The affectation had lasted four months before the council killed it.

On duty, Miller would have taken an electric cart down the wide tunnels and down to the port levels. He was tempted even though he was off duty, but a deep-seated superstition stopped him. If he took the cart, he was going as a cop, and the tubes ran just fine. Miller walked to the nearest station, checked the status, and sat on the low stone bench. A man about Miller’s age and a girl no more than three came in a minute later and sat across from him. The girl’s talk was as fast and meaningless as a leaking seal, and her father responded with grunts and nods at more or less appropriate moments.

Miller and the new man nodded to each other. The girl tugged at her father’s sleeve, demanding his attention. Miller looked at her-dark eyes, pale hair, smooth skin. She was already too tall to be mistaken for an Earth child, her limbs longer and thinner. Her skin had the pink flush of Belter babies, which came with the pharmaceutical cocktail that assured that their muscles and bones would grow strong. Miller saw the father notice his attention. Miller smiled and nodded toward the kid.

“How old?” he asked.

“Two and a half,” the father said.

“Good age.”

The father shrugged, but he smiled.

“Kids?” he asked.

“No,” Miller said. “But I’ve a got a divorce about that old.”

They chuckled together as if it was funny. In his imagination, Candace crossed her arms and looked away. The soft oil-and-ozone-scented breeze announced the tube’s arrival. Miller let father and child go first, then chose a different compartment.

The tube cars were round, built to fit into the evacuated passages. There were no windows. The only view would have been stone humming by three centimeters from the car. Instead, broad screens advertised entertainment feeds or commented on inner planet political scandals or offered the chance to gamble away a week’s pay at casinos so wonderful that your life would seem richer for the experience. Miller let the bright, empty colors dance and ignored their content. Mentally, he was holding up his problem, turning it one way and then the other, not even looking for an answer.

It was a simple mental exercise. Look at the facts without judgment: Havelock was an Earther. Havelock was in a portside bar again and looking for a fight. Havelock was his partner. Statement after statement, fact after fact, facet after facet. He didn’t try to put them in order or make some kind of narrative out of them; that would all come later. Now it was enough to wash the day’s cases out of his head and get ready for the immediate situation. By the time the tube reached his station, he felt centered. Like he was walking on his whole foot, was how he’d described it, back when he had anyone to describe it to.

The Blue Frog was crowded, the barn-heat of bodies adding to the fake-Mumbai temperature and artificial air pollution. Lights glittered and flashed in seizure-inducing display. Tables curved and undulated, the backlight making them seem darker than merely black. Music moved through the air with a physical presence, each beat a little concussion. Hasini, standing in a clot of steroid-enhanced bouncers and underdressed serving girls, caught Miller’s eyes and nodded toward the back. Miller didn’t acknowledge anything; he just turned and made his way through the crowd.

Port bars were always volatile. Miller was careful not to bump into anyone if he could help it. When he had to choose, he’d run into Belters before inner planet types, women before men. His face was a constant mild apology.

Havelock was sitting alone, with one thick hand wrapping a fluted glass. When Miller sat down beside him, Havelock turned toward him, ready to take offense, nostrils flared and eyes wide. Then the surprise registered. Then something like sullen shame.

“Miller,” he said. In the tunnels outside, he would have been shouting. Here, it was barely enough to carry as far as Miller’s chair. “What’re you doing here?”

“Nothing much to do at the hole,” Miller said. “Thought I’d come pick a fight.”

“Good night for it,” Havelock said.

It was true. Even in the bars that catered to inner planet types, the mix was rarely better than one Earther or Martian in ten. Squinting out at the crowd, Miller saw that the short, stocky men and women were nearer a third.

“Ship come in?” he asked.

“Yeah.”

“EMCN?” he asked. The Earth-Mars Coalition Navy often passed through Ceres on its way to Saturn, Jupiter, and the stations of the Belt, but Miller hadn’t been paying enough attention to the relative position of the planets to know where the orbits all stood. Havelock shook his head.

“Corporate security rotating out of Eros,” he said. “Protogen, I think.” A serving girl appeared at Miller’s side, tattoos gliding over her skin, her teeth glowing in the black light. Miller took the drink she offered him, though he hadn’t ordered. Soda water.

“You know,” Miller said, leaning close enough to Havelock that even his normal conversational voice would reach the man, “it doesn’t matter how many of their asses you kick. Shaddid’s still not going to like you.”

Havelock snapped to stare at Miller, the anger in his eyes barely covering the shame and hurt.

“It’s true,” Miller said.

Havelock rose lurching to his feet and headed for the door. He was trying to stomp, but in the Ceres spin gravity and his inebriated state, he misjudged. It looked like he was hopping. Miller, glass in hand, slid through the crowd in Havelock’s wake, calming with a smile and a shrug the affronted faces that his partner left behind him.

The common tunnels down near the port had a layer of grime and grease to them that air scrubbers and astringent cleaners could never quite master. Havelock walked out, shoulders hunched, mouth tight, rage radiating from him like heat. But the doors of the Blue Frog closed behind them, the seal cutting off the music like someone hitting mute. The worst of the danger had passed.
