He looked for the assassin's weapon, did not see it. "I'm going to try to get onto that roof."

"Why? Shouldn't we get out of here?"

Another click. Civilians started screaming for the police. Outworlds civilians, anyway.

"Yeah, I guess. If he had anybody with him we would have heard from them by now." But where to go? he wondered. Not the hotel. Not with the number officially on. Not with the war rules proclaimed. And not to a safehouse. He did not yet know what Mouse had arranged. And he could not make the fallbacks to find out with Marya tagging along.

The death threat had alerted the professional in him. Had raised barriers that would wall off the whole universe till he had sorted the friends from enemies and noncombatants.

"We could go to my place," Marya suggested.

Memories of countless spy and detective dramas battled for Niven's attention. Was it all a setup? Three misses at fifty meters seemed unlikely for even a clumsy assassin. But he did not want to believe that Marya was involved. She was such a magnetic, animal woman...

Believe it or not, only a cretin would have ignored the possibility completely. Survival had become the stake on the board.

He dared not let her know he was suspicious. "All right." He looked around fearfully, having no trouble projecting shakiness and confusion. "But I've got to do a couple of things first."

Their eyes met. And he knew. He did not want it to be, but it was true. She was the enemy. Right now she was trying to find an excuse to stay close to him that would not arouse his suspicions.

She was not a good actress. Under stress she could not control the body language signals that betrayed her thoughts.

He felt betrayed and hurt, though he had known her just one day.

He had always needed to be wanted. Not for whom or what he was, but just as a human being.

Human. Was she even human? There was no sure way of telling without complicated tests. Geneticists were certain that humanity and the Sangaree shared a prehistoric ancestry.

She might even be the new Sangaree Resident. The last one had been a woman.

"Where do you stay?" he asked.

She chose not to push. She explained how he could get to her apartment.

"You don't have to do this," he told her, then cursed silently. By saying that, he had tacitly admitted being the sniper's target. But sometimes it was necessary to take chances. He could at least feed her belief in his lack of suspicion. "It might be dangerous."

"That's all right. I've never been involved in anything like this." Feigned excitement illuminated her face. "What have I gotten myself into, Gun?"

It was smoke screen time. "Sweetheart, I don't know. I really don't. This is the second time I've been jumped, but nobody bothered to tell me why last time either. They tried it right in the Marcos before. The day we got here. And we don't even know anybody here. But people have been following me all the time, and... If you're an Old Earther, you sense things like that."

"Maybe it's not you. Maybe it's your friend."

"John? I never thought of that. I guess it's possible. I don't really know anything about him. The Corporation sent him. Anyway, whatever's going on, I mean to find out."

He had yielded just enough distorted truth, he hoped, to leave her with doubts. A lot depended on whether or not the opposition had been able to evade Mouse's bug-scans.

"Will you be all right, Marya? Should I walk you home?"

"I'll manage."

"Probably be safer without me, anyway. See you in a while." He glanced at the dead man, then the streets. Not a soul was stirring.

It was odd how people sensed a gathering storm, then stayed inside where they would witness nothing and run no risks. Though this was a warehouse district, there should have been some traffic. Hell. Where were the security patrols? Where were the police cruisers?

He had seen the same thing happen on Old Earth, where the gangs went to their guns at the slightest provocation. Citizens and enforcers always kept a low profile till the stink of gunsmoke left the air.

Mouse was not at the first fallback, nor had he left a message. Niven did find a hastily scribbled message at the second. It told him that Marya was the new Sangaree Resident. And, as if in afterthought, Mouse went on to say that he was on the run from a dozen men who had gotten onto him after the incident at the warehouse.

Niven scratched a reply, explaining where he would be. The drop was large, so he left the notes he had taken at the Med Center.

Those had to be salvaged no matter what. Maybe by Chief Navy Recruiter for The Broken Wings. He was the Bureau Angel City station chief.

Niven began drifting, killing time in order to give Marya a chance to make a move that would illuminate the outfit's current thinking. After an hour he picked up a sticktight.

His shadow was a sleepy-faced thug pretending to be a derelict. A not-too-bright offworlder, Niven decided. Angel City was too young and thoroughly ordered to sustain even a one-man Bowery.

The man did not move in. They were hoping he would lead them to Mouse.

He observed his shadow's tradecraft more out of curiosity than concern. The man was a professional but unaccustomed to this kind of work. He was probably a shooter or runner grabbed simply because he was available. He could be shaken at leisure. Niven shifted him to the back burner of awareness.

He drifted toward Marya's apartment. His nerves settled. He decided what he was going to do.

He did not relax completely. They might catch Mouse. Then his life would be worthless. But while Mouse remained at large, he was sure, they would not harm him.

He shook the sticktight, found a public comm, woke the Angel City station chief, explained where the Med Center information was hidden. He used a word code the other side would need hours to unravel—assuming they were tapping at all.

He reached Marya's apartment as dawn began coloring the dome. The molecularly stacked plastic glimmered redly. As the sunlight changed its angle of incidence, the plastic would alternate between transparency and a progression up an iridescent spectrum.

He was tired but still alert, and exhilarated because he had handled himself well.

Marya responded to his knock instantly. "Where have you been? she demanded. "I've been worried sick." She peered over his shoulder, along the second floor hallway.

Checking for Mouse? For her backup?

"Somebody started following me around. I didn't know what to do, so I just walked around till he gave up. Or I lost him."

"Gun, I don't understand all this. Why?... "

"Honey, I don't know. And I've been thinking hard. All I can figure is maybe one of Ubichi's competitors thinks I'm after something besides that research data... " He paused, pretending to have been startled by a thought. "Hey! They never did tell me why they want the data. I just assumed... Maybe it's for a project that's stepping on somebody's toes."

Had he been what he claimed, the possibility would have been real. Ubichi maintained its own armed forces. The frontier corporations played rough.

Uncertainty filled Marya's eyes for a moment.

Bureau miscalculated, he thought. He could have convinced her had he looked like a social psychologist. His cover could be checked all the way back to his birth. The Bureau was thorough that way. Especially Beckhart's section.

But Niven looked like an Old Earth heavy. And that was the death of any other credential a man could present.

"Mom? What's going on?" A dark-haired girl of seven or eight stumbled into the room. She ground sleepy eyes with the backs of her fists. She was small for her age, a breastless miniature of her mother.

"Brandy, this is my friend Dr. Niven. I told you about him."

"Oh."
