Zayon said stiffly, "That sounds reasonable, Devoure."

Devoure was still rubbing his eyes. "Take his gun then. Go over there and take it."

"Wait," said Bigman, "don't move yet. I want your word of honor that I won't be shot down or given to the robots. Devoure has to take me."

"My word of honor to you?" exploded Devoure.

"To me. But not from you. The word of one of the other two. They're wearing the uniform of the Sirian Service and I'll take their word. If I give them the needle gun, will they stand by and let you, Devoure, come and take me with your bare hands?"

"You have my word," said Zayon.

"And mine," added Yonge.

Devoure said, "What is this? I have no intention of touching the creature."

"Afraid?" asked Bigman softly. "Am I too big for you, Devoure? You've called me names. Do you want to put your muscles where your cowardly mouth is? Here's my needle gun, Servicemen."

He tossed the gun suddenly in Zayon's direction. Zayon reached out a hand and caught it neatly.

Bigman waited. Now for death?

But Zayon put the needle gun in his pocket.

Devoure called out, "Robots!" and Zayon called out with equal vigor, "Leave us, robots!"

Zayon said to Devoure, "He has our word. You'll have to take him into custody yourself."

"Or do I come after you?" Bigman called out in shrill mockery.

Devoure snarled wordlessly and strode hastily toward Bigman. The small Martian waited, slightly crouched, then took a small side step to avoid the arm reaching out for him and uncoiled like a tightly wound spring.

His fist struck the other's face with the dull impact of a mallet hitting a head of cabbage, and Devoure staggered back, stumbling into a sitting position. He stared at Bigman in stunned amazement. His right cheek had reddened and a trickle of blood made its slow way out of the corner of his mouth. He put his finger to it, drew it away, and looked at the blood with an almost comical disbelief.

Yonge said, "The Earthman is taller than he looks."

Bigman said, "I'm not an Earthman, I'm a Martian…… Stand up, Devoure. Or are you too soft?

Can't you do anything without robots to help you? Do they wipe your mouth when you're done eating?"

Devoure yelled hoarsely and jumped to his feet but did not rush Bigman. He circled him instead, breathing hard, watching out of inflamed eyes.

Bigman wheeled also, watching that panting body, soft with good living and robot help, watching the unskillful arms and clumsy legs. The Sirian, Bigman was sure, had never fought fist to fist before.

Bigman stepped in again, caught the other's arm with a sure and sudden motion, and twisted. With a howl Devoure flipped and fell prone.

Bigman stepped back. "What's the matter? I'm not a he; I'm just an it. What's your trouble?"

Devoure looked up at the two Servicemen with something deadly hi his eyes. He rose to his knees and groaned as he put a hand to his side where it had hit the ground.

The two Sirians did not make any move to help him. They watched stolidly as Bigman cut him down again and then again.

Finally Zayon stepped forward. "Martian, you will hurt him seriously if you continue. Our agreement was to let Devoure take you with his bare hands, and actually I think you have what you really wanted when you made the agreement. That's all. Surrender quietly to me now or I'll have to use the needle gun."

But Devoure, panting noisily, gasped, "Get away. Get away, Zayon, It's too late for that. Step back, I say."

He called out in a high-pitched yell, "Robots! Come here!"

Zayon said, "He'll surrender to me."

"No surrender," said Devoure, Ms swollen face twitching with physical pain and intense fury. "No sur render. Too late for that… You, robot, the closest

one-I don't care what your serial number is-you. Take it-take that thing." His voice rose to a scream as he pointed to Bigman. "Destroy it! Break it! Break each piece of it!"

Yonge shouted, "Devoure! Are you mad? A robot can't do a thing like that."

The robot remained standing. It did not move.

Devoure said, "You can't harm a human being, robot. I'm not asking you to do so. But this is not a human being."

The robot turned to look at Bigman.

Bigman shouted, "It won't believe that. You may consider me non-human, but a robot knows better."

Devoure said, "Look at it, robot. It talks and has a human shape, but so do you and you're no human. I can prove it's not human. Did you ever see a full-grown human so small? That proves it's not human. It's an animal and it is-it is harming me. You must destroy it."

"Run to Mamma Robot," yelled Bigman mockingly.

But the robot took the first step toward Bigman.

Yonge stepped forward and moved between the robot and Bigman. "I can't allow this, Devoure. A robot must not do such a thing, even if for no other reason than that the stress of potential involved will ruin it."

But Devoure said in a hoarse whisper, "I'm your superior. If you make one move to stop me, I'll have you out of the Service by tomorrow."

The habit of obedience was strong. Yonge fell back, but there was a look of intense distress and horror on his face.

The robot moved more quickly, and now Bigman fell back a cautious step. "I'm a human being," he said.

"It is not human," cried Devoure madly. "It is not human. Break every piece of it. Slowly."

A chill fell over Bigman and left his mouth dry. He had not counted on this. A quick death, yes, but this…

There was no room to retreat, and he was without the escape his needle gun afforded. There were other robots behind, and all were hearing the word that he was not human.

There was a smile on Devoure's puffed and bruised face. It must have hurt him, for one lip was split and he dabbed absently at it with his handkerchief, but his eyes were fixed on the robot moving toward Bigman and he seemed aware of nothing else.

The small Martian had only another six feet in which to retreat, and Devoure made no effort to hasten the approaching robot or to move up those in the rear.

Yonge said, "Devoure, for Sinus's sake, man, there is no need of this."

"No comments, Yonge," said Devoure tensely. "That humanoid has destroyed a robot and probably damaged others. We'll need checkups on every robot who has been affected by the sight of his use of violence. He deserves death."

Zayon put out a restraining hand toward Yonge, but the latter slapped it impatiently away. Yonge said, "Death? All right. Then ship him back to Sirius and have him tried and executed according to the processes of law. Or set up a trial here at the base and have him decently blasted. But this is no execution. Simply because he beat… "

Devoure cried in sudden fury, "That's enough! You have interfered once too often. You're under arrest. Zayon, take his blaster and toss it over to me."

He turned briefly, loath to take his eyes off Bigman for even a moment. "Do it, Zayon, or by all the devils of space I'll break you too."

With a bitter, wordless frown Zayon held out his hand to Yonge. Yonge hesitated, and his fingers curled about the butt of bis blaster, half drawing it in anger.

Zayon whispered urgently, "No, Yonge. Don't give him the excuse. He'll lift arrest when his madness is over. He'll have to."

Devoure called out, "I want that blaster."

Yonge ripped it out of its holster with a hand that trembled and thrust it butt-first at Zayon. The latter tossed it at Devoure's feet and Devoure picked it up.

Bigman, who had been maintaining an agonized silence as he watched futilely for a chance to dodge, to break away, now cried out, "Don't touch me, I'm a master," as the robot's monstrous hand closed over bis wrist.
