“Correct,” Rydberg said. “It’s a relatively useless soft metal that is a by-product of our mining operations. Its one major virtue besides its use as a conductor is the fact that it doesn’t tarnish, making it ideal for human eating utensils. We made these things for David’s visit.”
Derec watched the serving spoon slip from Katherine’s grasp to clang loudly against her plate. And for just a second her face turned white.
“That’s what you told me my name was,” Derec said, finding the coincidence a little too close for his comfort.
She fixed him with unfocused eyes, then shrugged, looking normal again. “It’s a common enough name on Spacer worlds,” she said, returning her attention to her plate.
She picked up the spoon and went back to the job at hand. Derec looked up at the robots who stood beside the table and the small servo Type-I:5 robot waiting patiently near the door for the return of the utensils.
“Would you care to sit with us while we eat?” Derec asked, and felt Katherine kick him under the table.
“Delighted,” Euler said without hesitation, and the two robots sat at table attentively, apparently enjoying in their way the human familiarity.
Derec took the serving spoon and began filling his own plate. “I take it that David was the other human who came here?” he asked.
“That is correct,” Rydberg said.
“Then he came in a ship?” Derec pressed.
“No,” Euler said. “He simply walked into the city one day.”
“From where?”
“I don’t know.”
“Aaaahhh!” Katherine yelled, spitting out food and grabbing for the glass of water, drinking furiously. The robots swiveled their heads to watch, then exchanged glances. “Are you trying to feed us or kill us?” she demanded.
“Our programming would never allow us to kill you,” Rydberg said. “That would be quite impossible.”
Derec tentatively dipped his spoon into the porridge-like mixture, taking a small bite. Not sour, not sweet, it simply had a strange, alien taste accompanied by a slight noxious odor, one he was also uncomfortable with.
“This stuff stinks!” Katherine said loudly, the robots looking at her, then turning expectantly toward Derec.
“She’s right,” Derec replied. “What is this?”
“A perfect, nontoxic mixture of local plant matter, high in protein and balanced carbohydrates,” Rydberg said. “It’s good for you.”
“The other human ate this?” Derec asked.
“Quite enthusiastically,” Euler said.
“No wonder he’s dead,” Katherine muttered. “This is simply unacceptable. You’re going to have to find us something else, something that tastes good.”
Derec took another bite, this time holding his nose. Disassociating the smell from the food helped some, but not too much. The gruel left an unpleasant aftertaste. How could the other man have eaten it and not complained? Less made sense all the time.
“How long before you can get us something else?” Derec asked.
“Tomorrow?” Rydberg suggested. “Although they were proud of this in food services. Finding something of equal nutritional value will be difficult.”
“Forget nutritional value to a degree,” Derec said. “Study other human foods and see how well those can be duplicated exactly with the know-how you have here.” He looked at Katherine. “We should probably try and choke some of this down to keep our strength.”
She nodded grimly. “I’d already figured that,” she said, and looked at Rydberg. “Bring me lots of water.”
The robot hurried to comply, fetching a gold pitcher from the servo-cart and refilling her cup.
“When did he die, this David?” Derec asked, holding his nose and taking another bite.
“Seven days ago,” Rydberg said, sitting again and carefully positioning the pitcher within everyone’s easy reach on the table.
“Well, that rules us out as suspect then,” Derec said happily. “We didn’t arrive here until last night.”
“You’ll have to excuse me,” Rydberg said politely, “but Katherine has already exhibited a penchant for speaking less than honestly-”
“What’s that supposed to mean?” Katherine said angrily.
“No disrespect intended,” Rydberg said. “It is simply the case that your veracity must be in question in light of our conversations of this afternoon. At this point, we don’t know if we can trust anything either of you says.”
“We don’t even know where this place is,” Derec said.
“Then how did you get here?” Euler asked, swiveling his head to stare directly at Derec.
“I… ” Derec began, then stopped himself. He wasn’t ready to admit any knowledge of the Key. It was their only weapon, their only potential salvation; he couldn’t give it over so early in the game. “I don’t know.”
Rydberg stared for several seconds before saying, “To believe you means that you either materialized out of the ether or were somehow brought here totally without your knowledge or consent.”
Derec responded by taking the conversation away from the robot’s control. “You say this David also seemed to appear out of nowhere. Did you ever question him about his origins?”
“Yes,” Euler said simply.
“And you know nothing about his background,” Derec said, trying to keep his mind off the food by concentrating on the investigation. Across from him, Katherine was swallowing her food whole and washing it down with large gulps of water. “How was he dressed?”
“He was naked,” Euler said. “And he stayed naked.”
The two humans shared a look. Nudity was common and casual on many Spacer worlds, but the climate here would hardly recommend it. “When can we see the body?” Derec asked.
“That’s not possible,” Euler told her.
“Why?”
“I cannot tell you why.”
“Cannot or will not?” Derec asked, exasperated.
“Cannot and will not,” Euler replied.
“Then how do you expect us to investigate the cause of death?” Kate asked.
“If either or both of you are the murderers,” Euler said, “you already know the cause of death.”
“You’ve already decided our guilt,” Derec said, pointing. “That’s not fair or just.”
“There are no other possibilities,” Rydberg said.
“When the possible has been exhausted,” Derec replied, “it is time to examine the impossible. We are innocent, and you can’t prove that we aren’t. It only follows that the death was caused by something else.”
“Humans can murder,” Euler said, as thunder crashed loudly outside. “Humans can lie. You are the only humans here, and murder has been done.”
“We came out of nowhere,” Derec returned. “So did David. Others could also have come out of nowhere, others you haven’t discovered yet. Why, had we committed a murder, would we stay around for you to catch?”
The robots looked at one another again. “You raised logical questions that must be answered,” Euler said. “We certainly sanction your investigation.”
“How can we investigate without full access?”
“With all the other resources at your command,” Rydberg said, then stood. “Are you finished eating?”
“For now,” Derec said. “We’ll want real food tomorrow, though.”
“We will do our best,” Euler said, and he, also, stood. “Until then, you will stay here.”
“I thought I might go out,” Derec said.
“The rains will come. It’s too dangerous. For your own safety, you will stay here tonight. We have found that we cannot be certain if what you tell us is correct, so we’re leaving a robot at the door to make certain you stay in.”
“You don’t know that we’ve done anything wrong. You can’t treat us like prisoners,” Katherine said.
“And we shall not,” Rydberg said, moving toward the door; the servo whirred up to the table, its metal talons pulling the bowls and plates into its innards.
“There are many things we need to talk with you about,” Derec said.
“Tomorrow will be the time,” Euler said. “We will have a long interview at a prescribed time, where many issues will be discussed. Until then, we cannot fit it into our schedule. We are currently quite busy.” The robots turned to go.
“A couple of questions first,” Derec said, hurrying to put himself between the door and the robots. “You say we aren’t prisoners, yet you have locked us up. How long do we have to stay in this place?”
