“Then, perhaps, if you will be so good, citizen, to invite him thither, I could explain to him his future position and our own.”

Heron muttered something between his fleshy lips, then he turned back towards the open door, solemnly spat twice on the threshold, and nodded his gaunt head once or twice in a manner which apparently was understood from within.

“No, sergeant, I don’t want you,” he said gruffly; “only the prisoner.”

A second or two later Sir Percy Blakeney stood in the doorway; his hands were behind his back, obviously hand-cuffed, but he held himself very erect, though it was clear that this caused him a mighty effort. As soon as he had crossed the threshold his quick glance had swept right round the room.

He saw Armand, and his eyes lit up almost imperceptibly.

Then he caught sight of Marguerite, and his pale face took on suddenly a more ashen hue.

Chauvelin was watching him with those keen, light-coloured eyes of his. Blakeney, conscious of this, made no movement, only his lips tightened, and the heavy lids fell over the hollow eyes, completely hiding their glance.

But what even the most astute, most deadly enemy could not see was that subtle message of understanding that passed at once between Marguerite and the man she loved; it was a magnetic current, intangible, invisible to all save to her and to him. She was prepared to see him, prepared to see in him all that she had feared; the weakness, the mental exhaustion, the submission to the inevitable. Therefore she had also schooled her glance to express to him all that she knew she would not be allowed to say—the reassurance that she had read his last letter, that she had obeyed it to the last word, save where Fate and her enemy had interfered with regard to herself.

With a slight, imperceptible movement—imperceptible to every one save to him, she had seemed to handle a piece of paper in her kerchief, then she had nodded slowly, with her eyes—steadfast, reassuring—fixed upon him, and his glance gave answer that he had understood.

But Chauvelin and Heron had seen nothing of this. They were satisfied that there had been no communication between the prisoner and his wife and friend.
