"You are not over confident of their loyalty," she said, with a sardonic little laugh.

He made no reply. Madame's searching gaze was fixed upon him; she would have given worlds to divine his thoughts. On the whole, she felt reassured that he knew nothing of the vital issues which centred round the powder factory to-night. She was pretty certain that Leroux would try to see her again to-day—he had probably not left the château, and was waiting his opportunity to have speech with her as soon as de Maurel had gone. Something would have to be devised, something thought of, to meet the unlooked-for eventuality of de Maurel's presence at the factory to-night. But for this Madame required solitude and a calm view of the new situation. For the moment she was supremely conscious of the desire to be alone. Ronnay's presence now jarred well nigh unbearably on her nerves; the calm way in which he regarded her and dictated his will to her, with a certainty that she would obey, irritated her past endurance.

She turned away from him, for she did not choose to let him see how maddened she was, how thoroughly shaken was her usual haughty placidity. She walked deliberately to the window and turned her back on him, her aristocratic fingers beating a devil's tattoo against the panes.

"I'd best go now," suggested de Maurel, after a while, in that same awkward manner of his which seemed only to have dropped from him when he was dealing with Leroux.

"You are in your own house, my good Ronnay," rejoined Madame coldly, and without turning to look at him; "you have a perfect right to come and go as you please."

"Then am I your obedient servant," he said placidly.

Madame, from where she stood, could feel that his whole attitude was one of complete detachment. Her wrath and her scorn had no more effect on him than Leroux' threats of a while ago. She knew instinctively that he bowed and took his leave in that clumsy manner which she abhorred. Then she heard him moving across the room, opening the door, and finally shutting it behind him.

Even then she did not turn round. She remained standing beside the window, gazing out into the distance—seeing nothing and yet still gazing—her mind fixed upon the one great, all-absorbing puzzle. What was to happen to-night? She never moved, while her ears caught the sound of that firm, dragging step as it slowly died away in the distance. Then, when even its echo had ceased to reverberate through the silent house, she caught at the heavy curtain beside her, for suddenly in her whole body there was a relaxing of the tension on her nerves, and for the first time in her life Madame de Mortain felt ready to swoon. But even when she was all alone she would have scorned an unnecessary exhibition of weakness. A few seconds sufficed her to regain her self-control. She turned away from the window at last and sat down beside the heavy desk whereat she had so often penned enthusiastic reports to the Royalist agents. She drew pen and ink closer to her and sat thinking for a while. She had a mind to send a letter to de Puisaye—a runner might be found quick and clever enough to deliver it into the hands of the Chouan leader in the Cerf-Volant woods and to bring back his answer before nightfall.

In any case, before she wrote Madame was bent on seeing Leroux again. Leroux alone, she thought, would be able to cope with the situation as it now presented itself. Leroux was a man of resource, as his correspondence with Madame over the wall of the exercising ground had proved. He was not greatly troubled with scruples, and though he was by nature a coward, his temper, when roused, was apt to be both defiant and ugly.

Moreover, he was wilful, and would know how to act without any very explicit instructions, which Madame, in the absence of the chiefs, was not prepared to give him.
