In spite of himself Berrington was touched. He had never regarded Sartoris as anything of an actor, and he seemed to be in deadly earnest now. Was it just possible that the man had it in him to do a kindly thing? If so it seemed a pity to thwart him. Berrington looked fairly and squarely into the eyes of the speaker, but they did not waver in the least. The expression of Sartoris's face was one of hopelessness, not free altogether from contempt.

"I can't say any more," he said. "Open the door by all means, and spoil everything. It is in your hands to do so and curse your own vulgar curiosity afterwards. Call me mad if you like, but I had planned to do a kind thing to-night."

"So that you may benefit from it in the end?" Berrington suggested.

"Well, put it that way if you like," Sartoris said with fine indifference. "But it does not matter. You can sit down again. The knocker has gone, evidently."

But the door sounded again. Sartoris turned aside with a sigh. Despite his suspicions, Berrington felt that his conscience was troubling him. He would never forgive himself if he prevented a kind action

being done to one who cruelly needed it. He rose and crossed the room.

"Let it be as you like," he said. "I will promise not to interfere. As soon as you have finished I should like to have a few words with you here. After that I shall feel free to depart."

Sartoris nodded, but the triumph that filled him found no expression on his face. Berrington was no better than a fool, after all; a few fair words had disarmed him. Sartoris would gain all he wanted and when that was done he would take good care that Berrington did not leave the house. The man was by no means at the end of his cunning resources yet. He moved his chair in the direction of the hall.

"You have made a very wise decision," he said. "And I thank you for having some confidence in me. Will you wait for me in the dining-room?"

Berrington intimated that he would go into the dining-room and smoke a cigar. He was free to depart now, but he was going to do nothing of the kind. Sartoris was likely to be engaged for some time, and meanwhile Berrington was able to make investigations. He was desirous of finding out the secret of the dining-room, the way in which things were changed there, and the like. Of course, it had all been done by human agency, and what one man can invent another can find out. There was not likely to be a more favourable opportunity.
