There was a sound from beyond the door that led to Calvin’s personal laboratories. It was the chiming sound of Lenny.
The robopsychologist broke off instantly, listening. She said, “Excuse me. I think Lenny is calling me.”
“Can it call you?” said Lanning.
“I said I’ve managed to teach it a few words.” She stepped toward the door, a little flustered. “If you will wait for me –”
They watched her leave and were silent for a moment. Then Lanning said, “Do you think there’s anything to what she says, Peter?”
“Just possibly, Alfred,” said Bogert. “Just possibly. Enough for US to bring the matter up at the directors’ meeting and see what they say. After all, the fat
is
in the fire. A robot has harmed a human being and knowledge of it is public. As Susan says, we might as well try to turn the matter to our advantage. Of course, I distrust her motives in all this.”
“How do you mean?”
“Even if all she has said is perfectly true, it is only rationalization as far as she is concerned. Her motive in all this is her desire to hold on to this robot. If we pressed her” (and the mathematician smiled at the incongruous literal meaning of the phrase) “she would say it was to continue learning techniques of teaching robots, but I think she has found another use for Lenny. A rather unique one that would fit only Susan of all women.”
“I don’t get your drift.” Bogert said, “Did you hear what the robot was calling?”
“Well, no, I didn’t quite –” began Lanning, when the door opened suddenly, and both men stopped talking at once.
Susan Calvin stepped in again, looking about uncertainly. “Have either of you seen – I’m positive I had it somewhere about – Oh, there it is.”
She ran to a corner of one bookcase and picked up an object of intricate metal webbery, dumbbell shaped and hollow, with variously shaped metal pieces inside each hollow, just too large to be able to fallout of the webbing.
As she picked it up, the metal pieces within moved and struck together, clicking pleasantly. It struck Lanning that the object was a kind of robotic version of a baby rattle.
As Susan Calvin opened the door again to pass through, Lenny’s voice chimed again from within. This time, Lanning heard it clearly as it spoke the words Susan Calvin had taught it.
In heavenly celeste-like sounds, it called out, “Mommie, I want you. I want you, Mommie.”
And the footsteps of Susan Calvin could be heard hurrying eagerly across the laboratory floor toward the only kind of baby she could ever have or love.

HILE
STEPPED
THROUGH
the inner lock door, and turned white as it closed behind him. The woman at the data station shivered as she felt his presence.
“I’m sorry, Sheila,” he said hastily. “Rob wanted to use the lock himself right away, and said I should defrost inside.”
“Why didn’t he come through first? Armor doesn’t have anything like your heat capacity.”
“He didn’t say.” ZH50 had stood still since entering, using his own power to warm up; the frost was already disappearing from his extremities. Sheila McEachern waited, knowing there was nothing to be gained by complaining to the robot, her irritation giving way to curiosity anyway as the lock cycled again. She could hope, but not be sure, that Robert Ling had not wanted to annoy just to gain her full attention.
The valve slid open to reveal a human figure, its armor’s gold background fogging briefly under a layer of white as the ship’s air touched it. The man unclamped his bulky helmet as its contrasting black started to show again, and flipped it back.
“Chile, you’re in the way. Why did you think I wanted you inside first? I was hoping to see the new display as soon –”
“I can answer that.” The woman snorted. “You didn’t tell him why, just sent him first. Otherwise he’d have taken the reason as an order and given me frostbite while he plugged into the console.”
“I would not have injured you, Sheila.”
“Of course not, Chile. But you wouldn’t have minded making me uncomfortable, with a real order on file.”
“And you’re still in my way,” Ling cut in impatiently. ZH50 crossed to the data console in a single floating step, uncovered its input jack, and inserted the plug now extending from the heel of his right hand. The woman controlled herself; his metal was still cold enough to feel from a few centimeters away, but at least the frost was gone. She aimed her annoyance more appropriately.
“Why all this rush for a new picture? Did you finally find something which isn’t too radiation-saturated to date?” She disapproved basically of sarcasm, but had more control over aim than fire power. Ling knew her well enough to ignore the second question.
“We caught another glimpse of Chile’s ghost.”
“We?”
“We. The lovebirds saw it too, so I’m not floating.”
“Did Chile?”
“Not this time, Sheila,” the robot answered for himself. “I was with Luis and Chispa near the Banjo, at Square Fifty-four. Robert and the Eiras were at Ninety-one.” The woman frowned.
“Then why the hurry to get Chile inside?” she asked. “He could have been here long before you, if you started at the same time from those areas.”
“I didn’t think of him until I was nearly back. Then I had an idea, and needed him to check it. Luis and Chispa found two more of those blocks a while ago. The Eiras and I heard them; you probably weren’t listening. Of course Chile hadn’t filed them with Dumbo yet.”
“I was listening. And your idea needs all their positions.”
“Right.” If Ling noticed the remaining sarcasm he ignored it. “Look. Whether we want to believe it or not, those cubes are artificial. Shape may be an intrinsic property of a natural crystal, but size isn’t. Even if they were life forms, they wouldn’t all match dimensions to four figures. It occurred to me that they might be sensors – detectors of some sort.”
“It occurred to Chispa days ago. You didn’t want to believe then that anyone else beat us to Miranda.”
“I know. I still don’t. There’s no way a group from Earth could have set up this expensive a trip in secret, and I can’t make myself believe the other explanation. We’ve been hoping for ETI too long. But I thought of a way of checking.” He smiled, with a distant look on his face as though he were contemplating the approach of Fame.
“And?”
“The things radiate – broadcast – infrared patterns, nonthermal ones, at unpredictable times.”
“I know.”
“Well, we’ve mapped way beyond the local horizon. If that IR output is being coordinated, there must be a central unit they can all reach. You could have Dumbo mark any points on the map which are in eyeball touch with
all
the cube positions at once. If we’re lucky, there’ll only be a few. If we’re very lucky –”
The woman was already keying at Dumbo, the central data unit.
“And if there aren’t any?” she asked dryly.
“Well, it won’t prove I’m wrong. It’ll just mean...” His voice trailed off as the display popped into view, and a grin split his freckled face. Sheila rolled her eyes zenithward; it
would
happen to Ling. As though he weren’t bubbly enough already.
Chile accompanied them, naturally. The display had indicated a projecting spur at the top of a cliff which Chispa Jengibre had called El Barco, from the shadow pattern the sun was casting along its face when she first saw it. It was in block ninety-two, a little over twenty kilometers from the
Dibrofiad.
The location was understandable enough by hindsight; there would be splendid line-of-sight coverage from there. However, a one-hundred-fifty meter fall on Miranda would be dangerous for a human being; even if no limbs were broken, damage to the armor needed against the airless heat sink and Uranian radiation was nearly certain. While
Dibrofiad’s
crew had gotten fairly used to two-plus percent normal gravity, this hadn’t made anyone a good walker; it was doubtful that anything ever would.
Chile, therefore, viewed a human trip to the cliff as a parent would his one-year-old toddling out on a diving board. The actual visit to the spur must be robot’s work, if it had to be done.
The walkers looked ridiculous, trunks leaning forward like a sprinter about to leave the block, but legs almost straight along the same line. Walking is essentially coordinated falling forward, and Miranda needs every advantage to provide much fall. Thrust came from lower leg muscles bending and straightening ankles to drive toes hooked into surface irregularities, since bending the knees very far made them hit the ground. Bumps and cracks were fortunately numerous, possibly due to the expansion of freezing water, though none of the crew had a clear idea how water could ever have been liquid this far from the sun. The “hikers” carried alpenstocks, but used a free finger more often than the stick to keep faces off the ground. Luis, Chispa’s husband, had remarked that walking could be called body-surfing if Miranda’s water were only melted. His wife insisted that the analogy was too strained, though it was she who had insisted on the robot’s name being spelled to look Spanish after the Gold team had won the throw for right to select the name itself.
Whatever one chose to call it, Sheila was as good at “walking” as Ling; everyone, regardless of specialty, shared the field exploration, which was the most time-consuming crew duty.
Chile would stay ahead of them, since he alone dared to leap. His memory held a detailed surface map for sixty or seventy kilometers around
Dibrofiad,
so he didn’t have to see his target; he could jump with enough spin control to be sure of landing on his feet; and being built to operate in the sixty Kelvin temperature range, he had no armor to worry about.
The greenish bulk of Uranus hung beyond Stegosaur, the same jagged ridge of carbon-darkened ice it had silhouetted ever since their arrival, changing visibly only in shape as the sun circled above it to produce phase. At the moment it was about eight hours from narrowest crescent, and a slight darkening of the green, showing through the deeper notches of Stego, showed that the fuzzy terminator of the gas giant would be in view shortly.
The party turned to put the planet to their left rear and the sun behind them, and set out. Neither of the other human couples could be seen, but Ling had reached them on the low-frequency sets to report that the Gold team was going out. Bronwen Eira, engineer and captain of
Dibrofiad,
had acknowledged.
Little was said even by Ling as they went; each person was coming to terms, in his or her own way, with the increasing certainty that they would be the first group to prove the reality of extraterrestrial intelligence. It was hard to believe, like the “yes” to a proposal. Sheila, accustomed to the rugged Miranda landscape as she was, found it now showing a strange, dreamlike aspect; Robert scarcely saw it at all through constantly changing visions of the futures the next hour or two might crystallize. His usual free-time occupation of talking his companion into sharing a name had been put aside, not entirely to her relief. Even the Green and Orange teams, the Jengibres and Eiras, though not going along, were having trouble concentrating on their work; all four had thought of dropping it and following the Golds, though none had so far suggested it aloud.
Travel was fast, in spite of its awkwardness. ZH50 spoke occasionally to guide his companions away from the deeper chasms, though one or the other of them would sometimes issue a startled gasp or exclamation when carried by a “step” over a drop deep enough to jar an Earth-trained nervous system but dismissed by the robot as safe. Their startlingly sharp shadows, that of each helmet surrounded by a Brocken halo visible only to its owner, pointed the way.
Dibrofiad
was quickly out of sight; even had Miranda been smooth, five kilometers would have put the ship below the horizon.
Finally Chile stopped them with a gesture. “We turn left here. A straight path toward the point marked by Dumbo would have brought us to the foot of Barco. Be careful; there is less than a kilometer to go. Be sure to aim no step beyond a spot you can see.”
The speed of the group slowed accordingly, until he stopped them again. “Tripod fashion from now on; use your sticks. No free fall.”
An unusually smooth horizon now faced them. Neither Rob nor Sheila could estimate its distance; none of the numerous wrinkles and shadows on the ground ahead offered any clue to size, and there was no reason to suppose the general surface was horizontal even if they had been able, in the feeble gravity, to be sure of vertical. They knew from the Dumbo display that there was a possibly lethal drop beyond the edge, but this could have been fifty meters away or five hundred.
“Where’s the spur?” Sheila asked.
“There.” Chile pointed. “Its tip has enough downslope to be invisible from where we stand, though if you jump straight up for a few meters you could distinguish
“Thanks, I’m not sure I could go straight up. I’ll take your word. What’s the actual distance?”
“We are just under one hundred fifty meters from the main line of the edge and from the base of the spur. I advise you not to get any closer, but if you want to see me all the way to the end, you will have to. Please go very slowly indeed, and do not pass me under any circumstances.”
Nearly erect now, using the alpenstocks, and never having more than one foot or stick off the ice at a time, the trio edged forward.
“I wish you would stay back,” Chile repeated when the distance had shrunk to fifty meters. “We have no data on the strength of this ice. We could be providing the heaviest load it has experienced since it formed. It would be much safer if I went forward alone and brought back whatever may be there.”
“No collecting yet, Chile,” Sheila replied. She made no comment on the danger the robot had implied, but was conscious of it. The cliff
might
even have an overhang. “Nothing gets moved from its original site until we make final decision about what’s coming home with us. We don’t want to spoil more than we can help for later researchers.”
The robot, who knew this perfectly well, made no reply; but both Sheila and Rob knew that First Law tension must be building up in him. They kept safely behind him as he approached the edge, the woman doing nothing to oppose her companion’s obvious intention to keep ahead of her, and stopped when they were close enough to see the far end of the projection.
