"Suppose we just say they knew I'd find a way to make Ramsey meet all of our demands." Henley smiled thinly. "The details they left to me." He paused an instant, then went on: "Right after Helen Ramsey disappeared, I did some hard thinking. It occurred to me that she might be wearing a mask too. So I watched all of the women in the quarantine cage and when one of them slipped out I followed her." "As simple as that!" "It wasn't simple. The girl's disappearance on the shuttle ship had me completely baffled at first. It wasn't until we reached the Station that the mask possibility occurred to me." "We talked about that once before, remember?" "You were lucky then, Corriston. I tried very hard to kill you, simply because I thought you knew more about Helen Ramsey's disappearance than you actually did. In that dark cargo compartment, with time running out on me, I couldn't think very clearly. Anything more you'd like to know?" "Yes. How many men did Ramsey succeed in substituting for the rightful officers? How many, beside the commander?" "Eight, including the commander. His real name was Henry Hervet. Five were executive officers, two were security guards. They're all dead now." Corriston's mouth went dry. "Including the one who sold out and helped you?" "Yes, Stockton was the first to die. He was dead before the others tried to board this ship. I made sure of that. He was too greedy for his own good." "You got back the money you gave him, I suppose." "Naturally. Money is of very little value to a dead man." Corriston had gone very pale. There was dread in his eyes when he asked: "And the real Commander Clement? What happened to him? Where is he now?" "Stockton told me that after a mask was made of his face he was imprisoned somewhere on the Station," Henley said. "Clement and seven others. Ramsey gave Hervet strict orders not to kill them. I don't know where Clement is now, but I can make a pretty good guess. He has probably been released and is in full command of the Station again." Henley stood very still for a moment, very straight and still, and Corriston could feel the gun nudging the small of his back again. "I may as well tell you now that I'm going to have to lock you in, Corriston," Henley said. "When I turn the key on this room your sole responsibility will be right here with the controls. You'll have to sleep and eat here, and I don't intend to bring you any fancy meals. You'll hear a knock on the door three times a day. You'll get a tray with some food on it. "You'll have to decide for yourself how much sleep you can afford to take. And remember this: I'll be keeping a careful check on every navigational move you make. Not a too accurate check, perhaps, but I'll know enough. If you throw the ship off course I'll find out about it, and I'll want to know why. Be ready with your answers and make sure they carry weight. Any more questions, Corriston?"
