"And that's blood, diluted-gorilla blood. It was found on Gnut's arms."
"Good Heaven!" Cliff managed to exclaim. "And there's no explanation?"
"Not even a theory. It's your big chance, wonder boy."
Cliff broke away from Gus, unable to maintain his act any longer. He couldn't decide what to do about his story. The press services would bid heavily for it-with all his pictures-but that would take further action out of his hands. In the back of his mind he wanted to stay in the wing again that night, but-well, he simply was afraid. He'd had a pretty stiff dose, and he wanted very much to remain alive.
He walked over and looked a long time at Gnut. No one would ever have guessed that he had moved, or that there had rested on his greenish metal face a look of sadness. Those weird eyes! Cliff wondered if they were really looking at him, as they seemed, recognizing him as the bold intruder of last night. Of what unknown stuff were they made-those materials placed in his eye sockets by one branch of the race of man which all the science of his own could not even serve to disfunction? What was Gnut thinking? What could be the thoughts of a robot-a mechanism of metal poured out of man's clay crucibles? Was he angry at him? Cliff thought not. Gnut had had him, at his mercy-and had walked away.
Dared he stay again?
Cliff thought perhaps he did.
He walked about the room, thinking it over. He felt sure Gnut would move again. A Mikton ray gun would protect him from another gorilla-or fifty of them. He did not yet have the real story. He had come back with two miserable architectural stills!
He might have known from the first that he would stay. At dusk that night, armed with his camera and a small Mikton gun, he lay once more under the table of supplies in the laboratory and heard the metal doors of the wing clang to for the night.
This time he would get the story-and the pictures.
If only no guard was posted inside!

Cliff listened hard for a long time for any sound which might tell him that a guard had been left, but the silence within the wing remained unbroken. He was thankful for that-but not quite completely. The gathering darkness and the realization that he was not irrevocably committed made the thought of a companion not altogether unpleasant.
About an hour after it reached maximum darkness he took off his shoes, tied them together and slung them around his neck, down his back, and stole quietly down the passageway to where it opened into the exhibition area. All seemed as it had been the preceding night. Gnut looked an ominous, indistinct shadow at the far end of the room, his glowing red eyes again seemingly right on the spot from which Cliff peeped out. As on the previous night, but even more carefully, Cliff went down on his stomach in the angle of the wall and slowly snaked across to the low platform on which stood the table. Once in its shelter, he fixed his shoes so that they straddled one shoulder, and brought his camera and gun holster around, ready on his breast. This time, he told himself, he would get pictures.
He settled down to wait, keeping Gnut, in full sight every minute. His vision reached maximum adjustment to the darkness. Eventually he began to feel lonely and a little afraid. Gnut's red-glowing eyes were getting on his nerves; he had to keep assuring himself that the robot would not harm him. He had little doubt but that he himself was being watched.
Hours slowly passed. From time to time he heard slight noises at the entrance, on the outside-a guard, perhaps, or maybe curious visitors.
At about nine o'clock he saw Gnut move. First his head alone; it turned so that the eyes burned stronger in the direction where Cliff lay. For a moment that was all; then the dark metal form stirred slightly and began moving forward-straight toward him. Cliff had thought he would not be afraid-much-but now his heart stood still. What would happen this time?
With amazing silence, Gnut drew nearer, until he towered an ominous shadow over the spot where Cliff lay. For a long time his red eyes burned down on the prone man. Cliff trembled all over; this was worse than the first time. Without having planned it, he found himself speaking to the creature.
"You would not hurt me," he pleaded. "I was only curious to see what's going on. It's my job. Can you understand me? I would not harm or bother you. I… I couldn't if I wanted to! Please!"
The robot never moved, and Cliff could not guess whether his words had been understood or even heard. When he felt he could not bear the suspense any longer, Gnut reached out and took something from a drawer of the table, or perhaps he put something back in; then he stepped back, turned, and retraced his steps. Cliff was safe! Again the robot had spared him!
Beginning then, Cliff lost much of his fear. He felt sure now that this Gnut would do him no harm. Twice he had had him in his power, and either time he had only looked and quietly moved away. Cliff could not imagine what Gnut had done in the drawer of the table. He watched with the greatest curiosity to see what would happen next.
As on the night before, the robot went straight to the end of the ship and made the peculiar sequence of sounds that opened the port, and when the ramp slid out he went inside. After that Cliff was alone in the darkness for a very long time, probably two hours. Not a sound came from the ship.
Cliff knew he should sneak up to the port and peep inside, but he could not quite bring himself to do it. With his gun he could handle another gorilla, but if Gnut caught him it might be the end. Momentarily he expected something fantastic to happen-he knew not what; maybe the mockingbird's sweet song again, maybe a gorilla, maybe-anything. What did at last happen once more caught him with complete surprise.
He heard a sudden muffled sound, then words-human words-every one familiar.
"Gentlemen," was the first, and then there was a very slight pause. "The Smithsonian Institution welcomes you to its new Interplanetary Wing and to the marvelous exhibits at this moment before you."
It was the recorded voice of Stillwell! But it was not coming through the speakers overhead, but, much muted, from within the ship.
After a slight pause it went on:
"All of you must… must-" Here it stammered and came to a stop. Cliff's hair bristled. That stammering was not in the lecture!
For just a moment there was silence; then came a scream, a hoarse man's scream, muffled, from somewhere within the heart of the ship; and it was followed by muted gasps and cries, as of a man in great fright or distress.
Every nerve tight, Cliff watched the port. He heard a thudding noise within the ship, then out the door flew the shadow of what was surely a human being. Gasping and half stumbling, he ran straight down the room in Cliff's direction. When twenty feet away, the great shadow of Gnut followed him out of the port.
Cliff watched, breathless. The man-it was Stillwell, he saw now-came straight for the table behind which Cliff himself lay, as if to get behind it, but when only a few feet away, his knees buckled and he fell to the floor. Suddenly Gnut was standing over him, but Stillwell did not seem to be aware of it. He appeared very ill, but kept making spasmodic futile efforts to creep on to the protection of the table.
Gnut did not move, so Cliff was emboldened to speak.
"What's the matter, Stillwell?" he asked. "Can I help? Don't be afraid. I'm Cliff Sutherland; you know, the picture man."
Without showing the least surprise at finding Cliff there, and clutching at his presence like a drowning man would a straw, Stillwell gasped out:
"Help me! Gnut… Gnut-" He seemed unable to go on.
"Gnut what?" asked Cliff. Very conscious of the fire-eyed robot looming above, and afraid even to move out to the man, Cliff added reassuringly: "Gnut won't hurt you. I'm sure he won't. He doesn't hurt me. What's the matter? What can I do?"
With a sudden accession of energy, Stillwell rose on his elbows.
