He saw the tall form of Bevill turning away from the door of "Le Prince d'Orange," and understood that the man, who had in his hearing denounced the other as a spy, had been to see if the latter had entered the inn. He saw, too, by looking up the one long street that led from the _place_, that the denouncer paused for a moment and then went swiftly along it. Seeing this, he understood, and himself followed swiftly, while now and again putting his hand in his breast as though to make sure of what was hidden there. "He is gone that way," he muttered, "and the other knows it. So, too, do I know it now. Between us we shall run the fox to ground." Thus they went on: the first man invisible to the last, but the second kept well in view by that last; then suddenly the latter paused. He paused, with a muttered imprecation; paused while withdrawing himself into the deep, dark stoop of an old house. "He has missed him! Missed him! He is coming back. The spy has escaped. Ah! ah! the chance is gone. If he has missed him how shall I ever find him?" A moment later this watcher started, while giving utterance to some sound that was, now, neither imprecation nor exclamation, but, in truth, a gasp. A gasp full of astonishment, nevertheless; a gasp that surprise seemed to have choked back into his throat. For he who was coming back was not the tall, handsomely apparelled young man who had started forth in pursuit of him whom he had denounced as a renegade spy; but, instead, another. An older man, one who held a dark cloak across his features from which some wisp of a grey beard projected; one who, as he came swiftly towards that stoop where the man was hidden, looked back and back, and back again, and glinted a pair of dark eyes up and down the street as though in mortal fear. "He's mine," the watcher whispered to himself. "He's mine. He will spy no more." As he so spoke, the man who was returning drew near the stoop, his footsteps fell outside it. He was before it! * * * * * * "How did I miss him? What twist or turn did the vagabond take whereby to avoid me?" Bevill pondered the next morning, as now the soft, roseate hue of the sun suffused the skies that, half an hour before, had been daffodil and, before that, lit by the moon. For it was four o'clock now, and the daylight had dawned on one of the last remaining days of May. Four o'clock! And Bevill Bracton, after he had re-entered his room, disheartened at having missed Sparmann, had sat from midnight until now on a chair at a table by the window, while sternly refraining from lying down for fear that, thereby, he might fall asleep and so be trapped by some of the French soldiery whom the spy would possibly have put on his track. He had asked himself the above question a dozen, a score, a hundred times during these hours. He had muttered again and again, "How did I miss him? How lose sight of him?" yet was always unable to find an answer to the question.
