There was a swaying and a creaking all about them, the slow, steady rumble of caterpillar treads, and Drever had almost to shout to make himself heard. He stood directly opposite Corriston, supporting himself by a guard rail, and watching the desert through the weather-shield change color in the wake of the heavy vehicle's heaving, churning, torpedo-shaped rear-end. "Stone's been unconscious now for an hour," Drever said, dividing his gaze between Corriston, and the loosely strapped-in, sleeping girl at his side, both swaying with the swaying tractor. "We can't count on getting any more information out of him. I can't wake him up. Drugs would be dangerous. I don't think he'll live, but we can't deliberately kill him to get him to talk." "I know that," Corriston said. "But he's the only one who knows why Henley is staying so long at the Citadel. He should have been back hours ago. He left before you escaped from the ship. For all we know, he may be dead. Ramsey may have lost his head and had him shot, although that seems unlikely. Ramsey would go to any length to save his daughter. But we've no way of knowing whether he believed Henley's story or not. Anything could have happened. Henley may have attacked Ramsey." "I've a feeling that he's still at the Citadel," Corriston said. "I'll have to gamble on that--the one-in-five chance that for some reason the negotiations have been prolonged. He may be lying dead in the desert somewhere. He may have been attacked by lamprenes. As you say, anything could have happened. But when I make up my mind to do something I usually go through with it. It's just a matter of plain common sense. You don't toss aside a decision you've given a great deal of thought to just because the arguments against it are weighty, too." "I see. So you're still determined to walk right up to the gate and tell them you're Stone." "Why not? They've never laid eyes on Stone and they don't know me from Adam. I won't be wearing this uniform. I'll tell them that Henley's expecting me, that he left orders for me to join him if he failed to come back at a specified time. I'll watch the guard's face and change my story a little--if I have to--as I go along." "It's a _very_ long gamble. I hope you realize that." "It's either that or no gamble at all. And we've _got_ to gamble. We're holding at least two high cards and a joker. Henley has had the ground shot right out from under him. He's completely alone, and the only thing he has left to gamble with is his nearness to Ramsey, his ability to terrify Ramsey by making him believe that his daughter's life is still in danger. Ramsey has to be told that Helen has been freed, has to be warned in time, before he does anything foolish.
