Drummond closed the door behind him, and stood for a moment in silence, looking round the hall. It was deserted, but he wanted to get the geography of the house firmly imprinted on his mind. Then a noise from the room he had just left made him frown sharply—his host was continuing the process of fortification—and he stepped across towards the drawing-room. Inside, as he hoped, he found the girl.

She rose the instant he came in, and stood by the mantelpiece with her hands locked.

“What was it?” she half whispered—“that awful noise at dinner?”

He looked at her gravely for a while, and then he shook his head. “Shall we leave it as a night-bird for the present?” he said quietly. Then he leaned towards her, and took her hands in his own. “Go to bed, little girl,” he ordered; “this is my show. And, may I say, I think you’re just wonderful. Thank God you saw my advertisement!”

Gently he released her hands, and walking to the door, held it open for her. “If by any chance you should hear things in the night—turn over and go to sleep again.”

“But what are you going to do?” she cried.

Hugh grinned. “I haven’t the remotest idea,” he answered. “Doubtless the Lord will provide.”

The instant the girl had left the room Hugh switched off the lights, and stepped across to the curtains which covered the long windows. He pulled them aside, letting them come together behind him; then, cautiously, he unbolted one side of the big centre window. The night was dark, and the moon was not due to rise for two or three hours, but he was too old a soldier to neglect any precautions. He wanted to see more of The Elms and its inhabitants; he did not want them to see more of him.

Silently he dodged across the lawn towards the big trees at the end, and leaning up against one of them, he proceeded to make a more detailed survey of his objective. It was the same type of house as the one he had just left, and the grounds seemed about the same size. A wire fence separated the two places, and in the darkness Hugh could just make out a small wicket-gate, closing a path which connected both houses. He tried it, and found to his satisfaction that it opened silently.

Passing through, he took cover behind some bushes from which he could command a better view of Mr. Lakington’s abode. Save for one room on the ground-floor the house was in darkness, and Hugh determined to have a look at that room. There was a chink in the curtains, through which the light was streaming out, which struck him as having possibilities.
