If it came from below or above, from the adjoining room or from

Outside in the road, Stuart knew not. But following hard upon the mysterious disturbance which had aroused him it seemed to pour ice into his veins, it added the complementary touch to his panic. For it was a kind of low wail—a ghostly minor wail in falling cadences—unlike any sound he had heard. It was so excessively horrible that it produced a curious effect.

Discovering from the dancing of the torch-ray that his hand was trembling, Stuart concluded that he had awakened from a nightmare and that this fiendish wailing was no more than an unusually delayed aftermath of the imaginary horrors which had bathed him in cold perspiration.

He walked resolutely to the door, threw it open and cast the beam of light on to the staircase. Softly he began to descend. Before the study door he paused. There was no sound. He threw open the door, directing the torch-ray into the room.

Cutting a white lane through the blackness, it shone fully upon his writing-table, which was a rather fine Jacobean piece having a sort of quaint bureau superstructure containing cabinets and drawers. He could detect nothing unusual in the appearance of the littered table. A tobacco jar stood there, a pipe resting in the lid. Papers and books were scattered untidily as he had left them, surrounding a tray full of pipe and cigarette ash. Then, suddenly, he saw something else.

One of the bureau drawers was half opened.

Stuart stood quite still, staring at the table. There was no sound in the room. He crossed slowly, moving the light from right to left. His papers had been overhauled methodically. The drawers had been replaced, but he felt assured that all had been examined. The light switch was immediately beside the outer door, and Stuart walked over to it and switched on both lamps. Turning, he surveyed the brilliantly illuminated room. Save for himself, it was empty. He looked out into the hallway again. There was no one there. No sound broke the stillness. But that consciousness of some near presence asserted itself persistently and uncannily.

"My nerves are out of order!" he muttered. "No one has touched my papers. I must have left the drawer open myself."

He switched off the light and walked across to the door. He had actually passed out intending to return to his room, when he became aware of a slight draught. He stopped.

Someone or something, evil and watchful, seemed to be very near again. Stuart turned and found himself gazing fearfully in the direction of the open study door. He became persuaded anew that someone was hiding there, and snatching up an ash stick which lay upon a chair in the hall he returned to the door. One step into the room he took and paused—palsied with a sudden fear which exceeded anything he had known.
