"Indeed," said Randolph, with increased interest. "What is it? The answer to that puzzle has always bothered me."
"They say that the spy was a woman of great beauty, and she found it impossible to escape from Richmond until an officer of ours, yielding to her claims, helped her through the lines. I'll wager that he took full pay for his trouble."
"His honour against hers," said some one.
Harley laughed coarsely.
Prescott became deathly white. He would have fought a duel then with Harley—on the instant. All the Puritan training given him by his mother and his own civilized instincts were swept away by a sudden overwhelming rush of passion.
His colour came back and none noticed its momentary loss, all eyes being on Harley. Prescott glanced at Mr. Sefton, but the Secretary remained calm, composed and smiling, listening to Harley with the same air of interested curiosity shown by the others. Prescott saw it all with a flash of intuition; the Secretary had given Harley a hint, just a vague generalization, within the confines of truth, but without any names—enough to make those concerned uneasy, but not enough to put the power in any hands save those of the Secretary. Harley himself confirmed this by continuing the subject, though somewhat uncertainly, as if he were no longer sure of his facts.
It occurred to Prescott that he might borrow this man's own weapons and fight him with the cold brain and craft that had proved so effective against himself, Robert Prescott. But when he turned to look at the Secretary he found Mr. Sefton looking at him. A glance that was a mingling of fire and steel passed between the two; it was also a look of understanding. Prescott knew and the Secretary saw that he knew. In the bosom of James Sefton respect rose high for the young man whom he had begun to hold rather cheap lately. His antagonist was entirely worthy of him.
Harley rambled on. He looked uncertainly now and then at Prescott, as if he believed him to be the traitorous officer and would provoke him into reply; but Prescott's face was a perfect mask, and his manner careless and indifferent. The suspicions of the others were not aroused, and Harley was not well enough informed to go further; but his look whenever it fell on Robert was full of hatred, and Prescott marked it well.
"What do you think of a fellow who would do such a thing?" asked Harley at last.
"I've a pretty good opinion of him," said Raymond quietly.
