Caves of Steel - Isaac Asimov [44]
Fastolfe shook his head. “Please, Mr. Baley, you are being unreasonable. Really, you have the most astonishing notions. Suppose now, just quietly suppose, that R. Daneel is really R. Daneel. Suppose he is actually a robot. Wouldn’t it follow that the corpse Commissioner Enderby saw was really Dr. Sarton? It would be scarcely reasonable to believe that the corpse were still another robot. Commissioner Enderby witnessed R. Daneel under construction and can vouch for the fact that only one existed.”
“If it comes to that,” said Baley, stubbornly, “the Commissioner is not a robotics expert. You might have had a dozen such robots.”
“Stick to the point, Mr. Baley. What if R. Daneel is really R. Daneel? Would not the entire structure of your reasoning fall to the ground? Would you have any further basis for your belief in this completely melodramatic and implausible interstellar plot you have constructed?”
“If he is a robot! I say he is human.”
“Yet you haven’t really investigated the problem, Mr. Baley,” said Fastolfe. “To differentiate a robot, even a very humanoid robot, from a human being, it isn’t necessary to make elaborately shaky deductions from little things he says and does. For instance, have you tried sticking a pin into R. Daneel?”
“What?” Baley’s mouth fell open.
“It’s a simple experiment. There are others perhaps not quite so simple. His skin and hair look real, but have you tried looking at them under adequate magnification. Then again, he seems to breathe, particularly when he is using air to talk, but have you noticed that his breathing is irregular, that minutes may go by during which he has no breath at all. You might even have trapped some of his expired air and measured the carbon dioxide content. You might have tried to draw a sample of blood. You might have tried to detect a pulse in his wrist, or a heartbeat under his shirt. Do you see what I mean, Mr. Baley?”
“That’s just talk,” said Baley, uneasily. “I’m not going to be bluffed. I might have tried any of those things, but do you suppose this alleged robot would have let me bring a hypodermic to him, or a stethoscope or a microscope?”
“Of course. I see your point,” said Fastolfe. He looked at R. Daneel and gestured slightly.
R. Daneel touched the cuff of his right shirt sleeve and the diamagnetic seam fell apart the entire length of his arm. A smooth, sinewy, and apparently entirely human limb lay exposed. Its short, bronze hairs, both in quantity and distribution, were exactly what one would expect of a human being.
Baley said, “So?”
R. Daneel pinched the ball of his right middle finger with the thumb and forefinger of his left hand. Exactly what the details of the manipulation that followed were, Baley could not see.
But, just as the fabric of the sleeve had fallen in two when the diagmagnetic field of its seam had been interrupted, so now the arm itself fell in two.
There, under a thin layer of fleshlike material, was the dull blue gray of stainless steel rods, cords, and joints.
“Would you care to examine Daneel’s workings more closely, Mr. Baley?” asked Dr. Fastolfe politely.
Baley could scarcely hear the remark for the buzzing in his ears and for the sudden jarring of the Commissioner’s high-pitched and hysterical laughter.

ELUCIDATION BY A SPACER
The minutes passed and the buzzing grew louder and drowned out the laughter. The dome and all it contained wavered and Baley’s time sense wavered, too.
At last, he found himself sitting in an unchanged position but with a definite feeling of lost time. The Commissioner was gone; the trimensic receiver was milky and opaque; and R. Daneel sat at his side, pinching up the skin of Baley’s bared upper arm. Baley could see, just beneath the skin, the small thin darkness of a hyposliver. It vanished as he watched, soaking
