“Superficially, I grant it,” his brother acknowledged. “As a matter of scientific fact, I recognize the probability of your actually being a person utterly different from what you appear. Man becomes what he is according to the circumstances by which he is assailed. Now your life here, George, must be a singularly uneventful one.”

“Not during the last six months,” Lord Ashleigh remarked, with a sigh. “Even these last few days have been exciting enough. I must confess that they have left me with a queer sort of nervousness. I find myself listening intently sometimes,—conscious, as it were, of the influence or presence of some indefinite danger.”

“Very interesting,” the Professor murmured. “Spiritualism, as an exact science, has always interested me very much.”

Lady Ashleigh made a little grimace.

“Don’t encourage George,” she begged. “He is much too superstitious, as it is.”

There was a brief silence. The port had been placed upon the table and coffee served. The servants, according to the custom of the house, had departed. The great apartment was empty. Even Quest was impressed by some peculiar significance in the long-drawn-out silence. He looked around him uneasily. The frowning regard of that long line of painted warriors seemed somehow to be full of menace. There was something grim, too, in the sight of those empty suits of armour.

“I may be superstitious,” Lord Ashleigh said, “but there are times, especially just lately, when I seem to find a new and hateful quality in silence. What is it, I wonder? I ask you but I think I know. It is the conviction that there is some alien presence, something disturbing lurking close at hand.”

He suddenly rose to his feet, pushed his chair back and walked to the window, which opened level with the ground. He threw it up and listened. The others came over and joined him. There was nothing to be heard but the distant hooting of an owl, and farther away the barking of some farmhouse dog. Lord Ashleigh stood there with straining eyes, gazing out across the park.

“There was something here,” he muttered, “something which has gone. What’s that? Quest, your eyes are younger than mine. Can you see anything underneath that tree?”

Quest peered out into the grey darkness.
