David Bohlen, building a dam of wet soil at the end of his family's vegetable garden under the hot midafternoon Martian sun, saw the UN police 'copter settle down and land before the Steiners' house, and he knew instantly that something was going on.

A UN policeman in his blue uniform and shiny helmet stepped from the 'copter and walked up the path to the Steiners' front door, and when two of the little girls appeared the policeman greeted them. He then spoke to Mrs. Steiner and then he disappeared on inside, and the door shut after him.

David got to his feet and hurried from the garden, across the stretch of sand to the ditch; he leaped the ditch and crossed the patch of flat soil where Mrs. Steiner had tried unsuccessfully to raise pansies, and at the corner of the house he suddenly came upon one of the Steiner girls; she was standing inertly, picking apart a stalk of wur-weed, her face white. She looked as if she were going to be sick.

"Hey, what's wrong?" he asked her. "Why's the policeman talking to your mom?"

The Steiner girl glanced at him and then bolted off, leaving him.

I'll bet I know what it is, David thought. Mr. Steiner has been arrested because he did something illegal. He felt excited and he jumped up and down. I wonder what he did. Turning, he ran back the way he had come, hopped once more across the ditch of water, and at last threw open the door to his own house.

"Mom!" he shouted, running from room to room. "Hey, you know how you and Dad always are talking about Mr. Steiner being outside the law, I mean in his work? Well, you know what?"

His mother was nowhere to be found; she must have gone visiting, he realized. For instance, Mrs. Henessy who lived within walking distance north along the ditch; often his mom was gone most of the day visiting other ladies, drinking coffee with them and exchanging gossip. Well, they're really missing out, David declared to himself. He ran to the window and looked out, to be sure of not missing anything.

The policeman and Mrs. Steiner had gone outside, now, and both were walking slowly to the police 'copter. Mrs. Steiner held a big handkerchief to her face, and the policeman had hold of her shoulder, as if he was a relative or something. Fascinated, David watched the two of them get into the 'copter. The Steiner girls stood together in a small group, their faces peculiar. The policeman went over and spoke to them, and then he returned to the 'copter--and then he noticed David. He beckoned to him to come outdoors, and David, feeling fright, did so; he emerged from the house, blinking in the sunlight, and step by step approached the policeman with his shining helmet and his armband and the gun at his waist.

"What's your name, son?" the policeman asked, with an accent.

"David Bohlen." His knees shook.

"Is Mother or Father home, David?"

"No," he said, "just me."

"When your parents return, you tell them to keep watch on the Steiner children until Mrs. Steiner is back." The policeman started up the motor of the 'copter, and the blades began to turn. "You do that, David? Do you understand?"

"Yes, sir," David said, noticing that the policeman had on the blue stripe which meant he was Swedish. The boy knew all the identifying marks which the different UN units wore. He wondered how fast the police 'copter could go; it looked like a special fast job, and he wished he could ride in it: he was no longer frightened of the policeman and he wished they could talk more. But the policeman was leaving; the 'copter rose from the ground, and torrents of wind and sand blew around David, forcing him to turn away and put his arm across his face.

The four Steiner girls still stood gathered together, none of them speaking. One, the oldest, was crying; tears ran down her cheeks but she made no sound. The smallest, who was only three, smiled shyly at David.

"You want to help me with my dam?" David called to them. "You can come over; the policeman told me it was O.K."

After a moment the youngest Steiner girl came toward him, and then the others followed.

"What did your dad do?" David asked the oldest girl. She was twelve, older than he. "The policeman said you could say," he added.

There was no answer; the girl merely stared at him.

"If you tell me," David said, "I won't tell anyone. I promise to keep it a secret."

Sunbathing out on June Henessy's fenced, envined patio, sipping iced tea and drowsily conversing, Silvia Bohlen heard the radio from within the Henessy house give the late afternoon news.

Beside her, June raised herself up and said, "Say, isn't he the man who lives next door to you?"

"Shh," Silvia said, intently listening to the announcer. But there was no more, only the brief mention: Norbert Steiner, a dealer in health foods, had committed suicide on a downtown New Israel street by throwing himself in the path of a bus. It was the same Steiner, all right; it was their neighbor, she knew it at once.

"How dreadful," June said, sitting up and fastening the straps of her polka-dot cotton halter. "I only saw him a couple of times, but--"

"He was a dreadful little man," Silvia said. "I'm not surprised he did it." And yet she felt horrified. She could not believe it. She got to her feet, saying, "With four children-- he left her to take care of four children! Isn't that dreadful? What's going to happen to them? They're so helpless anyhow."

"I heard,"June said, "that he deals on the black market. Had you heard that? Maybe they were closing in on him."

Silvia said, "I better go right home and see if there's anything I can do for Mrs. Steiner. Maybe I can take the children for a while." Could it have been my fault? she asked herself. Could he have done it because I refused them that water, this morning? It could be, because he was there; he had not gone to work yet.

So maybe it is our fault, she thought. The way we treated them--which of us has ever been really nice to them and accepted them? But they are such dreadful whining people, always asking for help, begging and borrowing... who could respect them?

Going into the house she changed, in the bedroom, to her slacks and T-shirt. June Henessy followed along with her.

"Yes," June said, "you're right--we all have to pitch in and help where we can. I wonder if she'll stay on or if she'll go back to Earth. I'd go back--I'm practically ready to go back anyhow, it's so dull here."

Getting her purse and cigarettes, Silvia said goodbye to June and set out on the walk back down the ditch to her own home. Breathless, she arrived in time to see the police 'copter disappearing into the sky. That was them notifying her, she decided. In the backyard she found David with the four Steiner girls; they were busy playing.

"Did they take Mrs. Steiner with them?" she called to David.

The boy scrambled at once to his feet and came up to her excitedly. "Mom, she went along with him. I'm taking care of the girls."

That's what I was afraid of, Silvia thought. The four girls still sat at the dam, playing a slow-motion, apathetic game with the mud and water, none of them looking up or greeting her; they seemed inert, no doubt from the shock of learning about their father's death. Only the smallest one showed any signs of reviving, and she probably had not comprehended the news in the first place. Already, Silvia thought, that little man's death has reached out and touched others, and the coldness is spreading. She felt the chill in her own heart. And I did not even like him, she thought.

The sight of the four Steiner girls made her quake. Am I going to have to take on these pudding-y, plump, vapid, low-class children? she asked herself. The answering thought thrust its way up, tossing every other consideration aside: _I don't want to!_ She felt panic, because it was obvious that she had no choice; even now they were playing on her land, in her garden--she had them already.

Hopefully, the smallest girl asked, "Miz Bohlen, could we have some more water for our dam?"

Water, always wanting water, Silvia thought. Always leeching on us, as if it was a trait born into them. She ignored the child and said instead to her son, "Come into the house--I want to talk to you."

Together, they went indoors, where the girls could not overhear.

"David," she said, "their father is dead, it came over the radio. That's why the police came and took her. We'll have to help out for a while." She tried to smile, but it was impossible. "However much we may dislike the Steiners--"

David burst out--"I don't dislike them, Mom. How come he died? Did he have a heart attack? Was he set on by wild Bleekmen, could that be?"

"It doesn't matter how he happened to die; what we have to think of now is what we can do for those girls." Her mind was empty; she could think of nothing. All she knew was that she did not want to have the girls near her. "What should we do?" she asked David.

"Maybe fix them lunch. They told me they didn't have any; she was just about to fix it."

Silvia went out from the house and down the path. "I'm going to fix lunch, girls, for any of you who want it. Over at your house." She waited a moment and then started toward the Steiner house. When she looked back she saw that only the smallest child was following.

The oldest girl said in a tear-choked voice, "No, thank you."

"You'd better eat," Silvia said, but she was relieved. "Come along," she said to the little girl. "What's your name?"

"Betty," the little girl said shyly. "Could I have a egg sandwich? And cocoa?"

"We'll see what there is," Silvia said.

Later, while the child ate her egg sandwich and drank her cocoa, Silvia took the opportunity to explore the Steiner house. In the bedroom she came upon something which interested her: a picture of a small boy with dark, enormous, luminous eyes and curly hair; he looked, Silvia thought, like a despairing creature from some other world, some divine and yet dreadful place beyond their own.

Carrying the picture into the kitchen she asked little Betty who the boy was.

"That's my brother Manfred," Betty answered, her mouth full of egg and bread. Then she began to giggle. Between the giggles a few hesitant words emerged, and Silvia caught the fact that the girls were not supposed to mention their brother to anyone.
