“Palpably a ruse to get me away from home.”

Harley dropped his cigarette into the ash tray beside the match, where, smouldering, it sent up a gray spiral into the air of the library. Whether because of his words or because of the presence of the man himself, the warning, intuitive finger had again touched Paul Harley. “You saw or heard nothing on your way across the square to suggest that any one having designs on your safety was watching you?”

“Nothing. I searched the shadows most particularly on my return journey, of course. For the thing cannot have been purposeless.”

“I quite agree with you,” said Paul Harley, quietly.

Between the promptings of that uncanny sixth sense of his and the working of the trained deductive reasoning powers, he was momentarily at a loss. Some fact, some episode, a memory, was clamouring for recognition, while the intuitive, subconscious voice whispered: “This man is in danger; protect him.” What was the meaning of it all? He felt that a clue lay somewhere outside the reach of his intelligence, and a sort of anger possessed him because of his impotence to grasp it.

Sir Charles was staring at him in that curiously pathetic way which he had observed at their earlier interview in Chancery Lane. “In any event,” said his host, “let us dine: for already I have kept you waiting.”

Harley merely bowed, and walking out of the library, entered the cosy dining room. A dreadful premonition had claimed him as his glance had met that of Sir Charles—a premonition that this man’s days were numbered. It was uncanny, unnerving; and whereas, at first, the atmosphere of Sir Charles Abingdon’s home had been laden with prosperous security, now from every side, and even penetrating to the warmly lighted dining room, came that chilling note of danger.

In crossing the lobby he had not failed to note that there were many Indian curios in the place which could not well have failed to attract the attention of a burglar. But that the person who had penetrated to the house was no common burglar he was now assured and he required no further evidence upon this point.

As he took his seat at the dining table he observed that Sir Charles’s collection had overflowed even into this room. In the warm shadows about him were pictures and ornaments, all of which came from, or had been inspired by, the Far East.

In this Oriental environment lay an inspiration. The terror which had come into Sir Charles’s life, the invisible menace which, swordlike, hung over him, surely belonged in its eerie quality to the land of temple bells, of silent, subtle peoples, to the secret land which has bred so many mysteries. Yes, he must look into the past, into the Indian life of Sir Charles Abingdon, for the birth of this thing which now had grown into a shadow almost tangible.
