“No,” Holden replied. “You aren’t coming along. You stay here with Amos and Alex. Give us”—he looked at his terminal—“three hours to go look and come back. If we aren’t here—”

“We leave you to the gangsters and the three of us get jobs on Tycho and live happily ever after,” Naomi said.

“Yeah,” Holden said with a grin. “Don’t be a hero.”

“Wouldn’t even consider it, sir.”

  Holden crouched in the shadows outside the maintenance hatch and watched as Ceres mobsters dressed in police riot gear led the citizens of Eros away in small groups. The PA system continued to declare the possibility of radiological danger and exhorted the citizens and guests of Eros to cooperate fully with emergency personnel. Holden had selected a group to follow and was getting ready to move when Miller placed a hand on his shoulder.

“Wait,” Miller said. “I want to make a call.”

He quickly dialed up a number on his hand terminal, and after a few moments, a flat gray Network Not Availablemessage appeared.

“Phone is down?” Holden asked.

“That’s the first thing I’d do, too,” Miller replied.

“I see,” Holden said even though he really didn’t.

“Well, I guess it’s just you and me,” Miller said, then took the magazine out of his gun and began reloading it with cartridges he pulled out of his coat pocket.

Even though he’d had enough of gunfights to last him the rest of his life, Holden took out his gun and checked the magazine as well. He’d replaced it after the shoot-out in the hotel, and it was full. He racked it and put it back in the waistband of his pants. Miller, he noticed, kept his out, holding it close to his thigh, where his coat mostly covered it.

It wasn’t difficult following the groups up through the station toward the inner sections where the radiation shelters were. As long as they kept moving in the same direction as the crowds, no one gave them a second look. Holden made a mental note of the many corridor intersections where men in riot gear stood guard. It would be much tougher coming back down.

When the group they were following eventually stopped outside a large metal door marked with the ancient radiation symbol, Holden and Miller slipped off to the side and hid behind a large planter filled with ferns and a couple of stunted trees. Holden watched the fake riot cops order everyone into the shelter and then seal the door behind them with the swipe of a card. All but one of them left, the remaining one standing guard outside the door.

Miller whispered, “Let’s ask him to let us in.”

“Follow my lead,” Holden replied, then stood up and began walking toward the guard.

“Hey, shithead, you supposed to be in a shelter or in the casino, so get the fuck back to your group,” the guard said, his hand on the butt of his gun.

Holden held up his hands placatingly, smiled, and kept walking. “Hey, I lost my group. Got mixed up somehow. I’m not from here, you know,” he said.

The guard pointed down the corridor with the stun baton in his left hand.

“Go that way till you hit the ramps down,” he said.

Miller seemed to appear out of nowhere in the dimly lit corridor, his gun already out and pointed at the guard’s head. He thumbed off the safety with an audible click.

“How about we just join the group already inside?” he said. “Open it up.”

The guard looked at Miller out of the corners of his eyes, not turning his head at all. His hands went up, and he dropped the baton.

“You don’t want to do that, man,” the fake cop said.

“I kind of think he does,” Holden said. “You should do what he says. He’s not a very nice person.”

Miller pushed the barrel of his gun against the guard’s head and said, “You know what we used to call a ‘no-brainer’ back at the station house? It’s when a shot to the head actually blows the entire brain out of someone’s skull. It usually happens when a gun is pressed to the victim’s head right about here. The gas’s got nowhere to go. Pops the brain right out through the exit wound.”

“They said not to open these up once they’d been sealed, man,” the guard said, speaking so fast he ran all the words together. “They were pretty serious about that.”

“This is the last time I ask,” Miller said. “Next time I just use the card I took off your body.”

Holden turned the guard around to face the door and pulled the handgun out of the man’s belt holster. He hoped all Miller’s threats were just threats. He suspected they weren’t.

“Just open the door, and we’ll let you go, I promise,” Holden said to the guard.

The guard nodded and moved up to the door, then slid his card through it and punched in a number on the keypad. The heavy blast door slid open. Beyond it, the room was even darker than the corridor outside. A few emergency LEDs glowed a sullen red. In the faint illumination, Holden could see dozensc hundredsof bodies scattered across the floor, unmoving.

“Are they dead?” Holden asked.

“I don’t know nothing about—” the guard said, but Miller cut him off.

“You go in first,” Miller said, and pushed the guard forward.

“Hold on,” Holden said. “I don’t think it’s a good idea to just charge in here.”

Three things happened at once. The guard took four steps forward and then collapsed on the floor. Miller sneezed once, loudly, and then started to sway drunkenly. And both Holden’s and Miller’s hand terminals began an angry electric buzzing.

Miller staggered back and said, “The doorc ”

Holden hit the button and the door slid shut again.

“Gas,” Miller said, then coughed. “There’s gas in there.”

While the ex-cop leaned against the corridor wall and coughed, Holden took out his terminal to shut off the buzzing. But the alarm flashing on its screen wasn’t an air-contamination alert. It was the venerable three wedge shapes pointing inward. Radiation. As he watched, the symbol, which should have been white, shifted through an angry orange color to dark red.

Miller was looking at his too, his expression unreadable.

“We’ve been dosed,” Holden said.

“I’ve never actually seen the detector activate,” Miller said, his voice rough and faint after his coughing fit. “What does it mean when the thing is red?”

“It means we’ll be bleeding from our rectums in about six hours,” Holden said. “We have to get to the ship. It’ll have the meds we need.”

“What,” Miller said, “the fuckc is going on?”

Holden grabbed Miller by the arm and led him back down the corridor toward the ramps. Holden’s skin felt warm and itchy. He didn’t know if it was radiation burn or psychosomatic. With the amount of radiation he’d just taken, it was a good thing he had sperm tucked away in Montana and on Europa.

Thinking that made his balls itch.

“They nuke the station,” Holden said. “Hell, maybe they just pretendto nuke it. Then they drag everyone down here and toss them into radiation shelters that are only radioactive on the inside. Gas them to keep them quiet.”

“There are easier ways to kill people,” Miller said, his breathing coming in ragged gasps as they ran down the corridor.

“So it has to be more than that,” Holden said. “The bug, right? The one that killed that girl. Itc fed on radiation.”

“Incubators,” Miller said, nodding in agreement.

They arrived at one of the ramps to the lower levels, but a group of citizens led by two fake riot cops were coming up. Holden grabbed Miller and pulled him to one side, where they could hide in the shadow of a closed noodle shop.

“So they infected them, right?” Holden said in a whisper, waiting for the group to pass. “Maybe fake radiation meds with the bug in it. Maybe that brown goo just spread around on the floor. Then whatever was in the girl, Julie—”

He stopped when Miller walked away from him straight at the group that had just come up the ramp.
