Suddenly Corriston had the answer. It came to him in a lightning-swift flash of intuition, which carried with it complete credibility. It was more than a guess. Somehow he was sure; he knew. A full minute before he heard the dull rumble of the tractors as they came through the gate, and went to the window and stared down, he knew.

He had the answer and yet what he saw eclipsed what he knew. It was a little like watching a rocket take off, hearing the roar and seeing the flames through all of its burning time, and seeing at the same time the men on the proving ground moving swiftly about, and the space-helmeted men at the controls of the rocket itself, each grimly intent on one particular task.

Ramsey was returning into the Citadel with armed guards on both sides of him, and his daughter was walking with her head erect at his side. Five colony tractors had followed him into the Citadel and two more were just coming through the gate, moving ponderously on their caterpillar treads because each tractor weighed two tons even in the light gravity of Mars.

Corriston did an almost unbelievable thing then. Standing quietly by the window he raised his right hand and saluted Ramsey in silent tribute to the man's courage at the most threatening moment of his life.

What Ramsey had done in no way lessened his guilt. But Corriston would have just as readily repeated the salute in public, without caring what anyone might think. What Ramsey had done was as clear to him now as a series of moves on a chessboard laid out in advance, but hidden from the man who was to be outwitted and outplayed.

Ramsey had made use of a double to keep Henley occupied—no doubt with repeated, skillful evasions, a constant insistence that more proof be forthcoming, more details supplied. Perhaps a half-dozen conferences had taken place in all, extending over many hours. And while Henley was being encouraged to believe that Ramsey was being softened up and would accept all of his demands in the end, Ramsey had gone out into the desert alone, armed, furious, and determined to rescue his daughter if it cost him his life.

Or perhaps he hadn't gone alone. Perhaps he had taken a dozen armed guards with him. Somehow it didn't seem important, couldn't take away Ramsey's moment of victory. It was a moment of victory for Ramsey even though he hadn't played a major role for long, even though he had found his daughter already rescued and safe on his return. And Corriston had been the one to move out into the center of the board and deliver the coup de grace. He had kept a restless killer immobilized while the play was under way, and that was victory enough for any man.

Corriston suddenly realized that neither Ramsey nor the Colonists had any way of knowing that Henley was dead. They had probably joined forces outside the Citadel for the sole purpose of rescuing him from the deadliest kind of danger. And he wasn't helping them at all. In another minute they'd be trying to get to him with tear gas.

It didn't make any kind of sense, but when Corriston went down the wide central staircase he wasn't thinking about the colonists at all. He was wondering only how Helen Ramsey would look standing alone on a strange dark headland at midnight. Then the vision dissolved and another one took its place. She wasn't on a headland any more.

She was standing at the door of a small, white cottage and there were a couple of kids beside her: a boy of about Freddy's age, or maybe a little younger, and a little girl with golden curls, her hair like a crown.
