The two shadows remained with heads held close together for some little time. It was plain to be seen that the woman was doing the greater part of the talking; the man gestured now and then as though in protest.

"She is urging him to something which he does not fancy," thought the secret agent, his keen eyes not missing a movement. "And, as his denials constantly grow fainter, and her urging more insistent, I think she will finally have her way."

Fancifully the two silhouettes went through their parts within the lighted square as cast by the gaslight upon the lawn. The woman pleaded and demanded; the man resisted with wide gestures and violently shaken head.

But, as the secret agent had told himself, the woman proved herself the stronger in the end. Sharp, imperious, even threatening grew her manner; and the man's protests died, his head ceased to shake, until finally his gestures were inquiring only, as of one who consents and desires only to know the best way of going about the matter in hand.

At this stage the shadow of the woman became still for the first time since it had appeared. It were as though she were endeavoring to recall something, or devise a plan. Then with an impatient gesture she snatched at a hand-bag which hung upon her arm and seemed about to open it. But with a contemptuous sweep of the hand the man waved it aside.

Again the two began their mute debate. This time it was the man who took the initiative; she had failed when she came to the carrying out of what she desired; apparently she had no clear conception of the thing she wanted done, and he was reproaching her for it.

But in the midst of this she stopped him. Her hand darted out, and from the wall she drew something, the shadow of which was so fine that Ashton-Kirk could not, at first, even guess as to its nature. But the way it swung out at her touch finally gave him a clue.

"A folding gas fixture," said he, softly.

Once more the girl took the aggressive; she gestured sharply and indicated frequently a point upon her left, some distance along the hall, and apparently a little above her head. The silhouette of the man remained motionless; what he heard was evidently bearing in upon him; his whole attitude seemed to say: "Here at last is something worth consideration."

Then there was a pause; the woman also became still; it were as though the two were measuring each other's strength. At length the man stepped toward the gas fixture, the woman drew back, and as she did so her hands went to her face as though she would shut out something repellent. With a handkerchief, the man brushed away any possible dust from the gas-burner; then he reached toward where the valve should be, and the half twist of his hand indicated that he had turned on the gas.
