Makki," came Taat's calm, controlled voice from the loudspeaker, "was 1615 hours. He had just finished lunch and was going back to the control room when I came onto the centerdeck from the storage deck below. Robwood came up from below a couple of minutes later and we ate supper together. "Robwood and I usually play a round of cards after supper when we're on the same schedule, but he was busy and I was in the middle of an experiment in the lab I have set up on the storage deck. We went down to the storage deck together. He went on below to the airlock and I started the moving picture camera again on my experiment. "I didn't go up again until Lefler sounded the alarm.

It barely eluded him. All he could remember was that it was something about Makki. Both Taat and Robwood were up by 0400 hours. They brought their breakfasts to the control room, along with coffee for Lefler. It was a pleasant meal for the three of them. No one really seemed to care that one of the others was a murderer, Lefler thought. They talked and acted more like companions in crime—or like the murderer was none of them, but someone lurking somewhere else in the ship. He wished he did not feel impelled to find out, if he could, who killed Makki. But he knew that Taat would be trying to find out, too—if Taat hadn't done
