He felt annoyed at himself again. It's the aliens, he thought, that are getting my nerves. I've pulled plenty of jobs as intricate as this without fretting this way. * * * * * He began another circuit around the building, and was at the rear when the voice said, almost at his shoulder, "Murdoch, Waverill wants you." His employer lay on his cot, looking drowsy. He scowled at Murdoch's footsteps. "Where you been? I want a drink." Murdoch involuntarily glanced around. "Will they let you have it, sir?" The voice came from the ceiling this time. "One ounce of hundred-proof liquor every four hours." "Is there any here?" Murdoch asked. "Tell us where to find it and we will get it from your ship." Murdoch told them where the ship's supply of beverages was stowed, and headed for the front of the building. The robot was already in the lobby. It allowed him to follow outside, but said, "Stand back from the barrier." Murdoch leaned against the building, trying not to show his eagerness. This was an unexpected break. He watched the ground level as the robot passed through the barrier. The dark line in the ground didn't change. The gravel stayed in place on both sides. Neither did the plants to the sides move. Evidently the barrier only opened at one spot to let things through. The robot had no trouble with the hatches, and came out quickly with a bottle in one hand. Murdoch worried again whether it had discovered that the ship's alarm was set. If so, it didn't say anything as it drew near. It handed Murdoch the bottle and disappeared into the building. After a few moments Murdoch followed. He found Waverill asleep, but at his footsteps the older man stirred. "Murdoch? Where's that drink?" "Right away, sir." Murdoch got ice from the alien's pantry, put it in a glass with a little water and poured in about a jigger of rye. He handed it to Waverill, then poured himself a straight shot. Rye wasn't his favorite, but it might ease his nerves a little. "Mm," said Waverill, "'S better." Murdoch couldn't see any marks on him. "Did they stick any needles into you, sir?" "I'm not paying you to be nosey." "Of course not, sir. I only wanted to know so I wouldn't touch you in a sore spot." "There are no sore spots," Waverill said. "I want to sleep a couple of hours, so go away. Then I'll want a steak and a baked potato." "Surely, sir." Murdoch went outside again and toured the grounds without seeing anything new. He went to the barrier and stared at the ship for a while. Then, to work off tension, he went into the gymnasium and took a workout. He had a shower, looked in on Waverill and found him still asleep, then went back to the library. The books and tapes were all Terran, with no clues about the aliens. The museum was no more helpful. It was a relief when he heard Waverill calling.
