acted the master. If his instructions had been to keep Baley from learning any more than was absolutely necessary, a trump card had been left in Baley's hand.

The other was only R. Daneel Olivaw, after all. All that was necessary was to tell Gruer, or any Solarian, that Daneel was a robot and not a man.

And yet, on the other hand, Daneel's pseudo humanity could be of great use, too. A trump card need not be played at once. Sometimes it was more useful in the hand.

Wait and see, he thought, and followed Daneel out to breakfast.

Baley said, "Now how does one go about establishing trimensional contact?"

"It is done for us, Partner Elijah," said Daneel, and his finger sought out one of the contact patches that summoned robots.

A robot entered at once.

Where do they come from, Baley wondered. As one wandered aimlessly about the uninhabited maze that constituted the mansion, not one robot was ever visible. Did they scramble out of the way as humans approached? Did they send messages to one another and clear the path?

Yet whenever a call went out, one appeared without delay.

Baley stared at the robotic newcomer. It was sleek, but not glossy. Its surface had a muted, grayish finish, with a checkerboard pattern on the right shoulder as the only bit of color. Squares in white and yellow (silver and gold, really, from the metallic luster) were placed in what seemed an aimless pattern.

Daneel said, "Take us to the conversation room." The robot bowed and turned, but said nothing. Baley said, "Wait, boy. What's your name?"

The robot faced Baley. It spoke in clear tones and without hesitation. "I have no name, master. My serial number" - and a metal finger lifted and rested on the shoulder patch - "is ACX-z745."

Daneel and Baley followed into a large room, which Baley recognized as having held Gruer and his chair the day before.

Another robot was waiting for them with the eternal, patient nonboredom of the machine. The first bowed and left.

Baley compared shoulder patches of the two as the first bowed and started out. The pattern of silver and gold was different. The checkerboard was made up of a six-by-six square. The number of possible arrangements would be infinite then, or seventy billion. More than enough.

Baley said, "Apparently, there is one robot for everything. One to show us here. One to run the viewer."

Daneel said, "There is much robotic specialization in Solaria, Partner Elijah."

"With so many of them, I can understand why." Baley looked at the second robot. Except for the shoulder patch, and, presumably, for the invisible positronic patterns within its spongy platinum iridium brain it was the duplicate of the first. He said, "And your serial number?"

"ACC-112, master."

"I'll just call you boy. Now I want to speak to a Mrs. Gladia Delmarre, wife of the late Rikaine Delmarre - Daneel, is there an address, some way of pin-pointing her location?"

Daneel said gently, "I do not believe any further information is necessary. If I may question the robot - "

"Let me do that," Baley said. "All right, boy, do you know how the lady is to be reached?"

"Yes, master. I have knowledge of the connection pattern of all masters." This was said without pride. It was a mere fact, as though it were saying: I am made of metal, master.

Daneel interposed, "That is not surprising, Partner Elijah. There are less than ten thousand connections that need be fed into the memory circuits, and that is a small number."

Baley nodded. "Is there more than one Gladia Delmarre, by any chance? There might be that chance of confusion."

"Master?" After the question the robot remained blankly silent.

"I believe," said Daneel, "that this robot does not understand your question. It is my belief that duplicate names do not occur on Solaria. Names are registered at birth and no name may be adopted unless it is unoccupied at the time."

"All right," said Baley, "we learn something every minute. Now see here, boy, you tell me how to work whatever it is I am supposed to work; give me the connection pattern, or whatever you call it, and then step out."

There was a perceptible pause before the robot answered. It said, "Do you wish to make contact yourself, sir?"

"That's right."

Daneel touched Baley's sleeve gently. "One moment, Partner Elijah."

"Now what is it?"

"It is my belief that the robot could make the necessary contact with greater ease. It is his specialization."

Baley said grimly, "I'm sure he can do it better than I can. Doing it
