“Aimée, if in this terrible fight for life I fall, and we do not meet again, I want you to promise me one thing. Will you, darling?”

“Of course, Edmond. What is it?”

“That you will never consent to marry that man, Arnaud Rigaux—our enemy?”

“I will never marry him, Edmond. I would rather die first?”

“You promise me that?” he asked eagerly.

“I promise you. Before I consent I would rather take my own life. I swear to you that I will never be the wife of Arnaud Rigaux.”

Bien! Remember always that he is our mutual enemy—yours and mine,” he said in a hard, determined tone. Then he again kissed her, reassured by her fervent promise.

As they stood beneath the lamplight, a sentry passed them, his bayonet gleaming beneath the fitful light. But they were both in ignorance that, away in the shadow of a doorway, a man who had just entered the square had withdrawn to watch the affectionate pair—out of curiosity perhaps.

Lovers are always interesting to the curious, yet this man who had hitherto walked very briskly, had suddenly stopped and withdrawn to the shadow, so suddenly indeed, that the heavy-footed sentry had not detected his light steps.

Had Edmond Valentin known that he was being spied upon, then woe-betide the watcher! The Belgians were again in occupation of the town, and any suspicious character was at once arrested as a German spy, of whom there were so many hundreds swarming all over the country.
