At four o’clock one morning, he lay awake, as often, listening to the strokes of the hall clock, which none of them could ever hear without a thrill, and slowly in at his bedroom door floated a dim, ghostly shape.

There was not sufficient light for him to discern more than the outline of what seemed to be a tall, gaunt figure, with a shawl over its head. Nearer to him the thing came, and the old Professor felt himself grow cold with fear. He had often boasted of his desire to see the ghost, and of his scorn of fear in connection therewith. But now, that the spectre had really appeared to him, the old man trembled all over, and tried in vain to cry out.

His throat contracted, his tongue was powerless, and a sort of paralysis of terror held him in thrall.

The approaching figure seemed not to walk, but progressed by a strange gliding motion, and came within a foot or two of the bed, where the Professor lay, shivering with dread.

Still but a misty wraith, the awful thing leaned over the prostrate man and as the shawled head drew near, Professor Hardwick saw dimly the face of his visitor, and it was a skull!

The fearsome sight of hollow eye-sockets and grinning, fleshless jaws, gave a sudden strength to the frightened man, and he uttered a faint terrorized scream.

Slowly the spectre raised a long, white-draped arm, and Hardwick saw a small glass tumbler in front of his face. Only for an instant, and then the phantom faded away, and vanished into space.

Again the Professor called out, and hurrying footsteps were heard in the hall.

Mr. Tracy was away in Boston, and Rudolph Braye had gone to New York, so the only other man in the house was Landon, who came hastily to the Professor’s door in his dressing-gown and slippers.

“What is it,” he asked, “did you call? Are you ill?”
