the icy water he shuddered, did an about-face and a minute later was in bed. Which couldn’t hold a candle to a ship’s bunk. His hand by itself groped around for the belts to buckle down the quilt, he gave a faint smile when he couldn’t find them; after all he was in a hotel, not threatened by any sudden loss of gravitation… That was his last thought. When he opened his eyes, he had no idea where he was. It was pitch black. “Tyndall!” he wanted to shout, and all at once—for no apparent reason—remembered how once Tyndall had burst terrified out of the cabin, in nothing but pajama bottoms, and desperately cried to the man on watch: “You! For God’s sake! Quick, tell me, what’s my name?!” The poor devil was plastered, he had been fretting over some imagined insult or other and drank an entire bottle of rum. In this roundabout way Pint’s mind returned to reality. He got up, turned on the light, went to take a shower, but then remembered about the water, so carefully let out first a small trickle—lukewarm; he sighed, because he yearned for a good hot bath, however after a minute or two, with the stream beating on his face and torso, he actually began to hum.
He was just putting on a clean shirt when the loudspeaker—he had no idea there was anything like that in the room—said in a deep bass:
“Attention! Attention! This is an important announcement. Will all men with military training please report immediately to Port Control, room 318, with Commodore-Engineer Achanian. We repeat. Attention, attention…” Pirx was so astonished, he stood there for a moment in only his socks and shirt. What was this? April fool? With military training? Maybe he was still asleep. But when he flung his arms to pull the shirt on all the way, he cracked his hand against the edge of the table, and his heart beat faster. No, no dream. Then what was it? An invasion? Martians taking over the Moon? What nonsense! In any case he had to go…
But something whispered to him while he jumped into his pants: “Yes, this had to happen, because
“I won’t find out anything now, I’m too late,” he thought, straightened his jacket and walked in. It was a small room, with three windows; behind them blazed an artificial lunar landscape, the unpleasant color of hot mercury. In the narrower part of the trapezoidal room stood two desks, the entire area in front of them being crammed with chairs, evidently brought in on short notice, since almost every chair was different. There were some fourteen-fifteen persons here, mostly middle-aged men, with a few kids who wore the stripes of navy cadets. Sitting apart was some elderly commodore—the rest of the chairs remained empty. Pirx took a seat next to one of the cadets, who immediately began telling him how six of them had flown in just the other day to start their apprenticeship “that side,” but they were given only a small machine, it was called a flea, and the thing barely took three, the rest had to wait their turn, then suddenly this business cropped up. Did Mr. Navigator happen to know…? But Mr. Navigator was in the dark himself. Judging by the faces of those seated, you could tell that they too were shocked by the announcement—they probably all came from the hotel. The cadet, it occurring to him that he ought to introduce himself, started going through a few gymnastics, nearly overturning his chair. Pirx grabbed it by the back, and then the door opened and in walked a short, dark-haired man slightly gray at the temples. He was clean- shaven, but his cheeks were blue with stubble, he had beetle brows and small, piercing eyes. Without a word he passed between the chairs, and behind the desk pulled down from a reel near the ceiling a map of “that side” on a scale of 1:1,000,000. The man rubbed his strong, fleshy nose with the back of his hand and said without preamble:
“Gentlemen, I am Achanian. I have been temporarily delegated by the joint heads of Luna 1 and Luna 2 for the purpose of neutralizing the Setaur.”
Among the listeners there was a faint stir, but Pirx still understood nothing—he didn’t even know what the Setaur was.
“Those of you who heard the radio are aware that here,” he pointed a ruler at the regions Hypatia and Alfraganus, “a swarm of meteors fell yesterday. We will not go into the effects of the impact of the others, but one—it may well have been the largest—shattered the protective shield over storage units B7 and R7. In the second of the two was located a consignment of Setaurs, received from Earth barely four days ago. In the bulletins it was reported that all of these met with destruction. That, gentlemen, is not the truth.”
The cadet sitting next to Pirx listened with red ears, even his mouth hung open, as if he didn’t want to miss a single word; meanwhile Achanian went on:
“Five of the robots were crushed beneath the falling roof, but the sixth survived. More precisely—it suffered damage. We think so for this reason, that as soon as it extricated itself from the ruins of the storage unit, it began to behave in a manner … to behave like a…”
Achanian couldn’t find the right word, so without finishing his sentence he continued:
“The storage units are situated near the siding of a narrow-gauge track five miles from the provisional landing field. Immediately after the disaster a rescue operation was initiated, and the first order of business was to check out all personnel, to see if anyone had been buried beneath the devastated buildings. This action lasted about an hour; in the meantime however it developed that from the concussion the central control buildings had lost their full seal, so the work dragged on till midnight. Around one o’clock it was discovered that the breakdown in the main grid supplying the entire construction site, as well as the interruption of telephone communication, had not been caused by the meteors. The cables had been cut—by laser beam.”
Pirx blinked. He had the irresistible feeling that he was participating in some sort of play, a masquerade. Such things didn’t happen. A laser! Sure! And why not throw in a Martian spy while you were at it? Yet this commodore- engineer hardly looked like the type who would get hotel guests up at the crack of dawn in order to play some stupid joke on them.
“The telephone lines were repaired first,” said Achanian. “But at that same time a small transporter of the emergency party, having reached the place where the cables were broken, lost radio contact with headquarters at Luna. After three in the morning we learned that this transporter had been attacked by laser and, as a result of several hits, now stood in flames. The driver and his assistant perished, but two of the crew—fortunately they were in suits, having gotten themselves ready to go out and repair the line—managed to jump free in time and hide in the desert, that is, the Mare Tranquillitatis, roughly here…” Achanian indicated with his ruler a point on the Sea of Tranquillity, some four hundred kilometers from the little crater of Arago. “Neither of them, as far as I know, saw the assailant. At a particular moment they simply felt a very strong thermal blast and the transporter caught fire. They jumped before the tanks of compressed gas went off; the lack of an atmosphere saved them, since only that portion of the fuel which was able to combine with the oxygen inside the transporter exploded. One of these people later died in as yet undetermined circumstances. The other succeeded in returning to the construction site, crossing a stretch of about one hundred and forty kilometers, but he ran and exhausted his suit’s air supply and went into anoxia—fortunately he was discovered and is presently in the hospital. Our knowledge of what happened is based entirely on his account and needs further verification.”
There was now a dead silence. Pirx too could see where all of this was leading, but he still didn’t believe it, he didn’t want to…
“No doubt you have guessed, gentlemen,” continued the dark-haired man in an even voice—his profile stood out black as coal against the blazing mercury landscapes of the Moon—“that the one who cut the telephone cables and high-tension line, and also attacked the transporter, is our sole surviving Setaur. This is a unit about which we know little, it was put into mass production only last month. Engineer Klarner, one of Setaur’s designers, was supposed to have come here with me, to give you gentlemen a full explanation not only of the capabilities of this model, but also of the measures that now must be taken with the object of neutralizing or destroying it…” The cadet next to Pirx gave a soft moan. It was a mean of pure excitement, that didn’t even make the pretense of sounding horrified. The young man was not aware of the navigator’s disapproving look. But then no one noticed or heard anything but the voice of the commodore-engineer.
“I’m no expert in intellectronics and therefore cannot tell you much about the Setaur. But among those
