to record star positions in the log every eight hours, or just every twelve hours now?" "Twelve, I think. But the Earth transit's on right now, and until Terra swings across that half a degree of the sun's face, we'd better take readings on that every four hours, anyhow." "Well, that's just for a little more than two days," said Robwood. "Look, Lefler, I'm overdue on my sleeping time anyway, so how about letting me make my statement on ... on Makki first?" "Blast away," said Lefler. "The mike's yours. We'll leave the control room so you'll feel freer to talk." Lefler munched thoughtfully on a hot sandwich. Across the control room, in the astrogator's chair, Taat sucked at a bulb of coffee. "Nice of you to fix up this lunch, Taat," said Lefler. "I'm not tied strictly to the control room during my watch, you know. But little things like this relax the tension." "Yes, it's a peculiar situation, Lefler," said Taat in a tone that indicated he had been thinking about it. "Psychologically, I mean. Now if there were only the two of us, and Makki drifting out there dead, both of us would know who shot him. With three of us, it's different. "You and I are sitting here talking as though neither of us killed Makki. Maybe you hadn't thought of it, but that means that tacitly, for now, we're assuming Robwood killed him. But, for all I know, you did. And, if you didn't, for all you know, I did." "Until we find out, I have to suspect you both," said Lefler flatly. "I could say the same thing," murmured Taat. "But one of us may be lying." "Of course, Makki could have shot himself, as Robwood suggested," said Lefler. "If he had relaxed his grip on the heat-gun after pressing the trigger, it would have drifted up away from him. There were the gloves, you know." "Why wouldn't Makki want his fingerprints on the gun if he were committing suicide?" objected Taat. "I'll concede that Makki had strong sadistic tendencies, but my guess is that the murderer put those gloves on him just to raise the possibility of suicide." Taat finished his coffee and left the control room. Lefler washed down the last bit of his sandwich with his own coffee and called White Sands on the radio. When he received an acknowledgment
